For example, the present specification discloses a problem in which the part described as "can be" is replaced with "is a problem" in the present specification. The issues are described as independent, and the intention is to acquire the rights to solve each issue independently by divisional application, amendment, etc. Even if the subject matter is implicitly grasped from the description in the specification, the applicant intends to make a part of the structure described in the specification amended or to be claimed in the divisional application. It also discloses a structure that solves problems that combine these independent problems, and has the intention to acquire rights.

The object of the present invention can be achieved, for example, by the following forms (1) to (23).

(1) A display device for displaying an image, a housing provided with an opening for viewing the image on the first direction side in a shaded internal space, and an image display unit arranged in the internal space. It is preferable that the display device includes a dimming member arranged on the first direction side of the image display unit at a distance from the image display unit.

By doing so, it is possible to prevent outside light from entering the internal space of the housing, and it is also possible to prevent the image light from the image display unit from directly reaching the eyes of the viewer. Therefore, it is possible to prevent the image recognized in the internal space of the housing from being difficult to see due to the combination of the image light from the image display unit and the external light, and a display device capable of obtaining high visibility of the displayed image. Can be provided.

(2) The dimming member may be arranged between the opening and the image display.

In this way, a space area is formed inside the housing on the side where the image is viewed rather than the dimming member, so that the space area can be used for a predetermined purpose.

(3) The surface of the dimming member on the first direction side may be inclined with respect to the display surface of the image display unit.

By doing so, when the viewer looks at the image display unit through the dimming member, it is possible to reduce the reflection of the viewer's face on the dimming member.

(4) The image display unit may display, as an image recognized as a three-dimensional image, a first image recognized that at least a part thereof exists on the opening side of the dimming member.

In this way, the viewer can obtain a feeling of being able to touch an image that can be recognized as a three-dimensional image.

(5) The image display unit displays the first image and a second image that is opposite to the first image and the first direction side or the first direction side as an image recognized as a three-dimensional image. It is preferable to selectively display any one of a plurality of images including the second image recognized to exist on the directional side.

In this way, any one of a plurality of images including the first image and the second image having different positions recognized as having an image recognized as a three-dimensional image by the viewer is selectively displayed. Therefore, it is possible to change the three-dimensional effect given to the viewer.

(6) Further having an audio output unit provided in the housing, the audio output unit is in the first direction of the first surface of the housing facing the internal space with respect to the dimming member. It is preferable that the lamp is provided on the side and at a position where the distance from the dimming member is smaller than the distance from the opening.

In this way, the sound output by the sound output unit may be reflected by the dimming member and transmitted to the viewer, so that the image itself displayed on the image display unit, for example, can be transmitted to the viewer. You can make it feel like you are hearing the sound. Further, since the audio output unit is arranged at a position where it is difficult for the viewer to see, the design of the display device can be improved.

(7) The upper end of the opening is provided further above the upper end of the display surface of the image display, and the upper surface of the internal space is from the upper end of the opening to the upper end of the display surface. It is better to incline downward toward the part.

(8) The image display unit may include a light source and a display body that modulates the light from the light source to display an image.

In the image display unit that modulates the light from the light source and displays the image, the light from the light source leaks out and the position of the light source is recognized by the viewer, so that the image emerges in the internal space. There is a risk that the floating feeling will be impaired. The presence of the dimming member makes it difficult for the light leaked from the light source to be visually recognized, so that a higher floating feeling of the image can be given.

(9) It is preferable that the upper end portion of the opening projectes toward the first direction side with respect to the lower end portion of the opening.

In this way, it is possible to prevent the light from above the display device from being reflected by the dimming member, thereby reducing the visibility of the image on the image display unit.

(10) The housing has a cover portion on the upper surface of the housing and has a storage space between the cover portion and the upper surface of the inner peripheral surface of the housing, and controls the display device. The unit may be arranged in the accommodation space.

In this way, maintenance of the control unit related to the display device can be performed by removing the cover unit provided on the upper surface of the housing. Therefore, the maintainability of the display device can be improved.

It is preferable to wire so as to pass through the gap area secured between and.

In this way, the power supply unit can be arranged at a position that is inconspicuous, and the position of the center of gravity of the display device can be lowered, which makes it easier to stabilize the posture. Further, the connection cord connecting the power supply unit and the control unit can be wired so as not to be seen by a visual eye.

(12) The cover portion is attached to the main body portion of the housing at a plurality of mounting positions, and the cover portion and the main body portion are the first of the plurality of mounting positions on the first direction side. At the mounting position 1, the first fixture is used to connect the housing at a position inside the outer peripheral wall of the housing, and the first mounting position of the display device is opposite to the first mounting position. At the second mounting position on the two-way side, it is preferable that the housing is joined from the outside of the outer peripheral wall of the housing by using a second fixture.

In this way, at the second mounting position, which is difficult for the eyes to see, the cover portion and the main body portion can be connected from the outside of the outer peripheral wall of the housing by using the second fixture that can be attached and detached from the outside of the outer peripheral wall. At the first mounting position, which is easily visible to the visual eye, the cover portion and the main body portion are coupled by using the first fixture in a place where it is difficult for the visual visual to see. The design of the device can be improved.

(13) Among the housings, the display device may further include an operation unit provided in a lower portion of the housing on the first direction side of the opening.

By doing so, when the viewer operates the operation unit, for example, the hand of the viewer does not overlap with the display image of the image display unit, and the viewer can operate the operation unit while looking at the display image of the image display unit. Can be operated. Therefore, it becomes easier for the visual operator to operate the operation unit, and the operability of the display device can be improved.

(14) It is preferable that the plurality of the dimming members are detachably provided.

(16) The motion detecting means is a behavior detecting sensor capable of detecting the behavior of an object, and the behavior detecting sensor may be arranged so as to detect a gesture performed in the internal space of the housing. ..

In this way, the behavior detection sensor can detect the gesture of the viewer, for example, in the internal space of the housing. Therefore, it is possible to suppress a decrease in the sensitivity of the behavior detection sensor as compared with the case where the behavior detection sensor is arranged on the outer peripheral surface of the housing.

(17) The behavior detection sensor may be arranged on the upper surface of the inner peripheral surface of the housing.

In this way, since the behavior detection sensor is provided on the inner peripheral surface of the housing where it is more difficult for light from the outside to enter, it is possible to suppress a decrease in the sensitivity of the behavior detection sensor.

(18) The behavior detection sensor is provided in the direction in which the light is emitted by emitting light and receiving the reflected light to detect the gesture, and the emitted light is received by the behavior detection sensor. It is preferable that the display device further includes a member for suppressing the above.

By doing so, it becomes difficult to receive the reflected light from the portion of the housing existing in the light emitting direction of the behavior detection sensor, so that the decrease in the sensitivity of the behavior detection sensor can be further suppressed.

(19) An odor sensor that detects an odor, a display output operation that displays an image of the character performing a movement according to the detection result of the odor sensor on the image display unit, and a sound corresponding to the detection result of the odor sensor. It is preferable to further include an operation control means for executing at least one of the sound output operation output as the sound emitted by the character displayed on the image display unit.

In this way, it is possible to reproduce the communication regarding the odor between the character displayed on the image display unit of the display device and the user. For example, when an odor is detected by an odor sensor, it is controlled so that a voice output operation in which the character emits a voice such as "smell something" or a video display output operation in which the character sniffs the odor is performed. obtain. Therefore, more diverse communication can be achieved between the character and the user.

(20) The display output operation is an operation of displaying an image of the character performing a movement according to the type of the detected odor on the image display unit, and the voice output operation is an operation of displaying the movement according to the type of the detected odor on the image display unit. It is preferable that the operation is to output the corresponding voice as the voice emitted by the character.

In this way, it is possible to reproduce the communication regarding the type of odor between the character displayed on the image display unit and the user. For example, when the odor of cigarettes is detected, a display output operation for displaying an image of a character performing a smoke-desired movement or a voice output operation for uttering words that care about the user's health can be executed. Further, when the odor of a fragrance such as aroma oil is detected, a voice output operation for asking a question about the fragrance can be executed. By performing such control, the range of communication between the character displayed on the image display unit and the user can be widened, and the user's attachment to the character can be increased.

(21) A voice detecting means capable of detecting voice and a detecting means capable of detecting the presence of a person in the detection target area are further provided, and the voice detecting means detects the presence of a person in the detection target area. And, it is preferable to enable voice recognition for performing a dialogue with the character displayed on the image display unit.

In this way, when interacting with the user and the character displayed on the image display unit, for example, the user does not need to utter a trigger word for enabling voice recognition, and communication can be performed more naturally. ..

[Outline configuration of display device]
FIG. 1 is a perspective view showing a display device 1 according to an example of the present invention. FIG. 2A is a front view showing a display device 1 according to an example of the present invention, and FIG. 2B is a rear view showing a display device 1 according to an example of the present invention. FIG. 3A is a right side view showing the display device 1 according to an example of the present invention, and FIG. 3B is a left side view showing the display device 1 according to an example of the present invention. FIG. 4A is a plan view showing a display device 1 according to an example of the present invention, and FIG. 4B is a bottom view showing a display device 1 according to an example of the present invention. FIG. 5 is an exploded perspective view showing a display device 1 according to an example of the present invention. FIG. 6 is a cross-sectional view taken along the line AA of FIG. 2A. Hereinafter, a schematic configuration of the display device 1 according to an example of the present invention will be described with reference to FIGS. 1 to 6.

In each drawing and the like, the left-right direction of the display device 1 is the X direction, and the direction from the left side to the right side of the display device 1 is the + X direction (positive direction in the X direction). Further, the front-rear direction (depth direction) of the display device 1 is the Y direction, and the direction from the front side (front side) to the back side (rear side) of the display device 1 is the + Y direction (positive direction in the Y direction). .. Further, the vertical direction of the display device 1 is the Z direction, and the direction from the lower surface side to the upper surface side of the display device 1 is the + Z direction (positive direction in the Z direction).

The display device 1 is used for various purposes. For example, the display device 1 may be used for commercial purposes (for example, for attracting customers, for advertising), for entertainment (for entertaining people), toys, and the like. For example, in the case of commercial or entertainment use, the display device 1 may be installed in a public place such as a store or other commercial facility. The display device 1 is used to attract customers by displaying an image in which a specific character introduces or promotes a product or service at a venue such as an exhibition of a product or service, and to entertain visitors. It is good. Alternatively, the display device 1 may be installed in various amusement facilities or the like and used to entertain visitors to the amusement facilities. In the case of a toy, the display device 1 is installed at the user's home or the like. Further, when a three-dimensional image is displayed on the display device 1 as described later, it may be used to entertain the viewer by allowing the viewer to experience the stereoscopic view of the display object. The viewer is, for example, a user who uses the display device 1.

As shown in FIG. 5, the display device 1 includes a housing 10, an image display unit 20 capable of displaying an image of an object to be displayed, and a dimming member 30.

The housing 10 is a box-shaped member that forms the outer shape of the display device 1. The housing 10 has a ratio of length (maximum length) in the width direction (also referred to as the left-right direction), the height direction (also referred to as the up-down direction), and the depth direction (also referred to as the front-rear direction) to be approximately 1: 1. It is 1. However, this length ratio is an example and may differ at least in part. The housing 10 has an R-shaped corner. For example, when the display device 1 is viewed from the front side, the four corners of the housing 10 are each rounded. The housing 10 may be large enough to accommodate an image display unit 20 of a predetermined size (for example, 17-inch size) inside the housing 10.

The housing 10 has an opening 5 on the front side (-Y side in each drawing) of the display device 1. The front side of the display device 1 corresponds to the side on which the viewer sees the image displayed by the display device 1. The opening 5 is formed on the front side of the display device 1 in the internal space of the housing 10. For example, as shown in FIG. 2A, the opening 5 is formed in a rectangular shape when viewed from the front side of the display device 1. The housing 10 has an internal space 100. The internal space 100 is a space in which an image is displayed in the space inside the housing 10. A portion of the internal space 100 other than the opening 5 is surrounded by a light-shielding member (see FIG. 6). External light does not enter the internal space 100 through the members constituting the housing 10. Therefore, the housing 10 may be entirely formed of a material that blocks external light, but the outer surface or the surface facing the internal space 100 may be covered with a material that blocks light. good. In FIG. 6, the internal space 100 is indicated by a alternate long and short dash line, and the two spatial regions 101 and 102 in which the internal space 100 is divided by the dimming member 30 are indicated by the alternate long and short dash line. The space area 101 is a space on the back side of the dimming member 30. The space region 101 has a larger dimension in the height direction toward the back side, and the dimension becomes smaller as it moves toward the front side. The space area 102 is a space on the front side of the dimming member 30. The space region 102 has a smaller dimension in the height direction toward the back side, and the dimension becomes larger as it moves toward the front side. In this embodiment, the opening 5 is specified by a planar region that connects the space region 101 to the external space. Therefore, the opening 5 may be read as an opening surface. The internal space 100 has a certain area in the depth direction (front-back direction) of the housing 10, and the housing 10 has a length in the depth direction toward the upper end as shown in the YZ cross section of FIG. Is longer than the bottom edge. The internal space 100 may be recognized by the viewer as, for example, a living room space of a character to be stereoscopically displayed.

For example, the housing 10 is made of a resin member or the like, and its surface (for example, at least one of an outer peripheral surface and an inner peripheral surface) is coated with a dark color (for example, black) rubber. .. As a result, light is prevented from entering the internal space 100 of the housing 10 from a portion other than the opening 5. It is not essential that the internal space 100 is surrounded by the light-shielding member in all the portions other than the opening 5, and the internal space 100 may be surrounded by the light-shielding member so as to be darkened to some extent. .. The housing 10 may be made of a material other than the resin material, for example, metal or other material. Further, the color of the outer surface of the housing 10 is not limited, but may be, for example, white or black that brings out a sense of quality or simplicity. The surface of the housing 10 may be processed so as to give a texture by a matte process.

Further, as shown in FIG. 5, the housing 10 includes a main body portion 11, a top cover portion 12, an arrangement portion 13 of the dimming member 30, a bottom cover portion 14, and a back cover portion 15. ing. Each member 12 to 15 is attached to the main body portion 11 by a fixing tool such as a screw, except for a part (described later) of the upper surface cover portion 12.

Next, the image display unit 20 will be described. The image display unit 20 is a display unit having a light source. Examples of the image display unit 20 include a liquid crystal display. In this case, the image display unit 20 includes a backlight which is an example of a light source and a display body 28 (see FIG. 5) in which a liquid crystal element which is an example of a display element is two-dimensionally arranged. The light source is, for example, a white light source. The liquid crystal element modulates the light from the backlight on a pixel-by-pixel basis. The liquid crystal element has, for example, a configuration in which liquid crystal molecules are sandwiched between a pixel electrode provided for each pixel and a common electrode common to a plurality of pixels. The image display unit 20 displays a color (multicolor) image based on the three primary colors of red (R), green (G), and blue (B). The image display unit 20 displays an image so as to be recognized as a three-dimensional image in this embodiment. The image display unit 20 is a 17-inch liquid crystal display in this embodiment.

The image display unit 20 is preferably configured to be capable of displaying a three-dimensional image of a display object, and is preferably a display capable of stereoscopic display with the naked eye. Further, it is more preferable that the image display unit 20 is configured so that the three-dimensional image and the two-dimensional image can be switched. The image display unit 20 may display an image of a display object such as a specific character (for example, a person or an animal). For example, it is preferable that the humanoid character 1000 is displayed and controlled in the image display unit 20 so as to be stereoscopically viewed by a viewer as shown in FIG. The character 1000 is a character imitating a historical person here, but may be a female character, an animal (for example, a cat) character, or another character. Not limited to this, various images can be displayed on the image display unit 20. Further, in the following, a character that is stereoscopically displayed (an example of a displayed object) is also referred to as a "3D character" or the like. A 3D character is an example of a 3D object.

As described above, the display device 1 may be a device capable of reproducing the stereoscopic display by the naked eye. Such a display device 1 is also referred to as, for example, a "naked-eye stereoscopic display device".

The autostereoscopic display may be reproduced by using, for example, a lenticular lens type image display unit 20. For example, the display surface 29 of the image display unit 20 is provided with a lenticular lens in which a plurality of semi-cylindrical lenses are arranged, and the image display unit 20 is a plurality of image sequences interlaced with respect to a three-dimensional image. Displays a group of image strings (also called lenticular images, etc.) composed of combinations. Then, when the viewer looks at the image sequence group from an appropriate position through the lenticular lens, the three-dimensional image appears three-dimensionally due to the optical illusion caused by the parallax of both eyes.

As shown in FIG. 6 and the like, the image display unit 20 is arranged in the internal space 100 of the housing 10 so that the image can be visually recognized from the opening 5 provided on the front side of the display device 1. For example, the image display unit 20 is arranged along the back surface (inner wall surface) of the inner peripheral surface of the housing 10. In this embodiment, as shown in FIG. 6, the back surface of the inner peripheral surface of the housing 10 is provided substantially perpendicular to the bottom surface of the housing 10, and the image display unit 20 is also provided on the housing 10. It is provided approximately perpendicular to the bottom surface.

Next, the dimming member 30 will be described. The dimming member 30 is an optical member that reduces external light entering the internal space 100 through the opening 5. The dimming member 30 is a plate-shaped (including a panel-shaped) or film-shaped member. Further, the dimming member 30 can reduce the amount of light from the image display unit 20 (for example, the light from the backlight of the image display unit 20). The dimming member 30 is provided to maintain the internal space 100 in a dark state. The reason will be described later. Further, the dimming member 30 suppresses the occurrence of reflection reflected on the dimming member 30 by the viewer who is viewing the image through the opening 5, and the internal parts of the internal space 100 can be visually recognized. It also contributes to making it difficult. The dimming member 30 may be a member called a smoke panel, a smoke film, or the like. Since the dimming member 30 transmits at least the image light from the image display unit 20 to the front side, it can be said to be an optically transparent member. Examples of the dimming member 30 include a dark-colored panel member having a predetermined light transmittance (for example, about 6%). The dimming member 30 is not limited to this, and may be, for example, a dark-colored film having a predetermined light transmittance attached to a colorless and transparent panel member. The dimming member 30 is a dark-colored member such as black, but may be bluish or other colors.

The dimming member 30 is arranged in the internal space 100 of the housing 10 on the front side of the image display unit 20 at a distance from the image display unit 20. In this embodiment, it is arranged between the opening 5 and the image display unit 20 so as to have a space area 101 (FIG. 6) between the image display unit 20 and the image display unit 20.

As described above, since the housing 10 has the light-shielded internal space 100, it is possible to prevent outside light from entering the internal space 100 of the housing 10, and for example, the front side of the image display unit 20. In addition, since the dimming member 30 is arranged at a distance from the image display unit 20, it is possible to prevent the image light from the image display unit 20 from directly reaching the eyes of the viewer. Therefore, it is possible to prevent the image recognized in the internal space 100 of the housing 10 from being difficult to see due to the combination of the image light from the image display unit 20 and the external light, and it is possible to obtain high visibility of the displayed image. The display device 1 can be provided.

Further, since the dimming member 30 is arranged between the opening 5 and the image display unit 20, a space area (for example, a space area 102 (for example, a space area 102) is provided on the front side of the dimming member 30 inside the housing 10. Since (see FIG. 6)) is formed, the space area can be used for a predetermined purpose.

Here, if there is no dimming member 30, and the viewer directly looks at the image display unit 20 itself on which the three-dimensional image of the display object is displayed, the light from the light source leaks out and the position of the light source. Is recognized by the viewer, so that the viewer can recognize that "the display object is reflected in the image display unit 20". As a result, it may not be possible to sufficiently obtain a floating feeling as if the image of the display object is floating in the internal space 100.

On the other hand, when the dimming member 30 is provided as described above, the amount of image light emitted from the peripheral region of the display object in the image display unit 20 is suppressed by the dimming member 30, and the image display unit 20 visually suppresses the amount of light. It becomes difficult for a person to see the surrounding area. As a result, the visual eye does not feel that the display object is reflected on the image display unit 20, and a floating feeling of the display object can be obtained. Therefore, it is possible to improve the visibility of the display image of the display object.

Further, for example, when the viewer sees the image display unit 20 itself on which the three-dimensional image of the display target is displayed as it is, the display target is displayed even though the display target is three-dimensionally viewed by the viewer. Blurred images may appear around objects. In such a case, the viewer may find it difficult to see the three-dimensional image of the display object.

On the other hand, when the dimming member 30 is provided as described above, the amount of light emitted from the image display unit 20 is reduced by the dimming member 30 and blurring around the display object. The image light of the image is reduced by the dimming member 30. As a result, it becomes difficult for the viewer to see the blurred image, and it becomes easy to recognize the display object as a three-dimensional image. Further, since the dimming member 30 is provided, it becomes difficult to visually recognize the parts existing in the internal space 100, so that it is unlikely that the viewer will be excited by being able to visually recognize such parts.

[Detailed configuration of each element]
Next, the detailed configuration of each element 10, 20, and 30 will be described.

The front surface of the dimming member 30 is inclined with respect to the vertical direction. In this embodiment, as shown in FIG. 6, the dimming member 30 is located on the opening 5 side (front side of the display device 1) from the upper end 31 to the lower end 32, for example, the bottom surface of the housing 10. It is provided so as to be inclined at a predetermined angle (for example, an angle of about 50 degrees). For example, as shown in FIG. 5, the upper surface of the arrangement portion 13 of the dimming member 30 is inclined at a predetermined angle with respect to the bottom surface of the housing 10, and the upper surface of the arrangement portion 13 has a dimming member. 30 is arranged.

In this way, the optical path of the reflected light of the light incident on the dimming member 30 exists in a direction different from that of the visual eye (or face) side. Therefore, when the viewer sees the image display unit 20 through the dimming member 30, it is possible to prevent the face of the viewer from being reflected on the dimming member 30 due to reflection. If such an object can be achieved, the inclination angle and the inclination direction of the dimming member 30 can be variously deformed. Therefore, it is possible to provide a display device 1 having higher visibility.

Further, inside the housing 10, a space area 102 (see FIG. 6) in which a viewer's hand can be placed can be provided on the opening 5 side of the dimming member 30.

Then, in the image display unit 20, at least a part of the display object (for example, a part of the body of a specific character) that is stereoscopically viewed by the viewer is displayed and controlled so as to exist at the arrangement position of the dimming member 30. It is good. In this way, the viewer touches the space region 102 on the opening 5 side of the dimming member 30, so that the display object emerges in the space region 102 and appears three-dimensionally (for example,). , Humanoid character 1000 (see FIG. 13), etc. An example of the first image) can be obtained. Therefore, for example, it is possible to provide a display device having excellent entertainment properties.

Further, by providing the space area 102 as described above, it is possible to increase the degree of freedom in the arrangement position of the gesture sensor 63 and the like, which will be described later.

As shown in FIGS. 2A and 6, the housing 10 further includes a speaker 62 (an example of an audio output unit). The speaker 62 is located on the surface of the housing 10 facing the internal space 100 on the front side of the dimming member 30 and at a position where the distance to the dimming member 30 is smaller than the distance to the opening 5. It will be provided. In this embodiment, the speaker 62 is the upper surface 85 of the internal space 100 of the housing 10, and is a dimming member from the intermediate position 201 between the upper end 21 of the dimming member 30 and the upper end 51 of the opening 5. It is provided on the 30 side (the back side of the housing 10).

In this way, the sound output by the speaker 62 may be reflected by the dimming member 30 and transmitted to the viewer, so that the display target displayed on the image display unit 20, for example, is displayed to the viewer. It can make the object (for example, a specific character) feel as if the sound is being heard from itself. This effect is particularly effective when the display is controlled so that at least a part of the display object (for example, a part of the body of a specific character) that is stereoscopically viewed by the viewer is present at the arrangement position of the dimming member 30. It is valid. Further, since the speaker 62 is arranged at a position where it is difficult for the viewer to see, the design of the display device 1 can be improved.

Further, as shown in FIG. 6, the upper end portion 51 of the opening 5 is provided above the upper end portion 21 of the image display unit 20 (specifically, the display surface 29), and is provided inside the housing 10. The upper surface 85 of the space 100 is provided so as to be inclined downward (in the −Z direction in FIG. 6) from the upper end 51 of the opening 5 toward the upper end 21. In this way, the image displayed on the image display unit 20 can be visually recognized while looking down from a position higher than the upper end portion 21 of the image display unit 20. Therefore, it is possible to make it easier for the viewer to visually recognize the image in a natural posture. For example, the display device 1 is placed on a desk. On the front side (front side) of the display device 1, there is a visual person standing or sitting on a chair. It is assumed that the position of the eyes of the viewer is higher than the upper surface of the display device 1. Therefore, the visual operator visually recognizes the display device 1 by looking down at an angle θ. The angle θ is the angle between the horizontal direction and the line-of-sight direction of the viewer. The angle θ is assumed to be, for example, 15 degrees, but it varies depending on the usage status of the display device 1. Based on the assumption of such an angle θ, the inclination angle of the upper surface 85 is determined so that the viewer can visually recognize the entire display surface of the image display unit 20 or the entire display area of the image to be visually recognized by the viewer. good. Further, it is possible to secure a relatively wide space area 110 for the control unit, which will be described later.

Further, as shown in FIG. 6, the upper end portion 51 of the opening 5 of the housing 10 is provided so as to project toward the front side (an example of the first direction side) from the lower end portion 52 of the opening 5. This protruding part is also called an eaves. By doing so, it is possible to suppress that the light from above the display device 1 is reflected by the dimming member 30 and the visibility of the image on the image display unit 20 is lowered.

As shown in FIGS. 1 and 6, an oblique portion 84 is provided on the opening 5 side (front side) in the lower portion of the housing 10. The side portion 53 of the opening 5 (see FIG. 3) is provided so as to be inclined at a predetermined angle from the upper end portion 51 of the opening portion 5 toward the vicinity of the upper portion 88 of the oblique portion 84. For example, the side portion 53 of the opening 5 is provided so as to be inclined so as to be substantially perpendicular to the dimming member 30.

Further, as shown in FIG. 6, the upper portion 88 of the skew portion 84 is provided above the lower end portion 22 of the image display portion 20, and the lower surface 86 of the internal space 100 of the housing 10 is the said. It is provided so as to be inclined downward from the upper portion 88 of the oblique portion 84 toward the lower end portion 22 of the image display unit 20.

Here, with respect to the stereoscopic display with the naked eye, the larger the so-called 3D feeling (three-dimensional effect), the smaller the display object to be stereoscopically viewed by the viewer. By inclining the lower surface 86 of the internal space 100 as described above, even when the 3D feeling is increased, the lower part of the display object (for example, the foot of a specific character) to be displayed stereoscopically is displayed. It can be displayed near the upper portion 88 of the skew portion 84.

Further, as shown in FIG. 1, the display device 1 includes an operation unit 40 that receives an operation on the display device 1. For example, in the display device 1, an operation unit 41 for performing voice input (also referred to as instructing the start of voice recognition) and a display setting for a three-dimensional image (for example, a setting value for parallax) are changed. Two operation units 40 with the operation unit 42 are provided.

These operation units 40 (41, 42) are provided in the lower portion of the housing 10 on the front side (an example of the first direction side) of the housing 10 with respect to the opening 5. In detail, as shown in FIG. 1, these operation units 40 (41, 42) are arranged in the oblique portion 84 provided on the opening 5 side in the lower portion of the housing 10. By doing so, when the viewer operates the operation unit 40, for example, the hand of the viewer does not overlap with the display image of the image display unit 20, and the viewer sees the display image of the image display unit 20. While operating the operation unit 40. Therefore, since it becomes easier for the visual operator to operate the operation unit 40, the operability of the display device 1 can be improved. Further, since the operation unit 40 is provided in the oblique portion 84, the visual operator can easily find the operation unit 40.

Next, various sensors provided in the display device 1 will be described.

The display device 1 further includes two motion detection units (an example of motion detection means capable of detecting the motion of the viewer) of the microphone 61 and the gesture sensor 63 (see FIG. 6). It is not essential that both of these two members 61 and 63 are provided in the display device 1, and only one of the microphone 61 and the gesture sensor 63 is used as the motion detecting means in the display device 1. It may be provided in.

The microphone 61 is configured as a voice detecting means capable of detecting the voice of a visual person such as a user (for example, a voice input operation). The microphone 61 is arranged, for example, in the oblique portion 84 described above (see FIG. 1). For the voice input using the microphone 61, for example, the general control unit 73 (described later) executes voice recognition processing, and for example, the voice recognition result indicated by text data or the like is acquired. The voice recognition process may be executed by a voice recognition device separately provided in the display device 1, or may be executed by an external server or the like different from the display device 1.

The gesture sensor 63 (an example of an object detection sensor) is configured to be able to detect the behavior of an object. Examples of the gesture sensor 63 include an infrared sensor and the like. The gesture sensor 63 has a light (for example, infrared light) emitting portion and a light receiving portion. The light emitted (also referred to as irradiation) from the exit portion of the gesture sensor 63 hits the detection object, is reflected, and is received by the light receiving portion. Then, the gesture sensor 63 detects the behavior of the object to be detected based on the light (reflected light) received by the light receiving unit. For example, when the same behavior as the specific behavior registered in advance in the gesture sensor 63 is detected, it is determined by the visual operator that the specific behavior has been performed.

For example, the gesture sensor 63 has a function (also referred to as a Wave detection function) that can detect whether or not the behavior is a predetermined behavior according to the movement of the hand. Then, for example, when the visual operator performs a waving motion (“bye bye”) or a stroking motion (“nadenade”) within the detection range of the gesture sensor 63, the gesture sensor 63 detects the wave motion and “bye bye” or It is advisable to judge it as "nadenade".

The gesture sensor 63 has a position of a detection object in the approaching / separating direction to the gesture sensor 63 (for example, the Z direction in FIG. 2A) and a plane having the approaching / separating direction as a normal (for example, FIG. 2 (for example)). In A), it is preferable that the position of the object to be detected on the XY plane) can be detected. For example, the plane may have four quadrants with the light receiving portion of the gesture sensor 63 as the origin. At this time, the X-axis may be set parallel to the left-right side of the front surface of the housing 10.

As shown in FIG. 2A, the gesture sensor 63 is installed at a substantially central position on the inner peripheral surface of the housing 10 in the left-right direction (X direction in FIG. 2A).

Further, as shown in FIG. 6, the gesture sensor 63 (specifically, the detection surface of the gesture sensor 63) is arranged on the inner peripheral surface of the housing 10 toward the inner side of the housing 10. The detection direction of the gesture sensor 63 is directed toward the inside of the housing 10. In this way, for example, the gesture of the viewer is detected in the internal space 100 of the housing 10, and in the present embodiment, the space area 102. Therefore, it is possible to suppress a decrease in the sensitivity of the gesture sensor 63 as compared with the case where the gesture sensor 63 is arranged on the outer peripheral surface of the housing 10.

Further, when the gesture sensor 63 is arranged on the outer peripheral surface of the housing 10, for example, the gesture sensor 63 may detect the behavior of the object to be detected even if a person passes around the display device 1. On the other hand, when the gesture sensor 63 is arranged on the inner peripheral surface of the housing 10 toward the inward side of the housing 10, such erroneous detection can be prevented.

In particular, as shown in FIG. 6, the gesture sensor 63 may be arranged on the upper surface 85 of the inner peripheral surface of the housing 10 toward the lower surface 86. In this way, the gesture sensor 63 is provided on the inner peripheral surface of the housing 10 where light from the outside does not easily enter. Therefore, the decrease in sensitivity of the gesture sensor 63 can be further suppressed as compared with the case where the gesture sensor 63 is provided on a surface other than the upper surface 85.

Further, the gesture sensor 63 is located on the upper surface 85 of the inner peripheral surface of the housing 10 at a position facing the boundary position 202 (see FIG. 6) between the upper portion 88 of the oblique portion 84 and the lower end portion 32 of the dimming member 30. It should be arranged. Then, it is preferable that the display is controlled so that the foot portion of the specific character is three-dimensionally displayed on the surface of the dimming member 30. In this way, it is possible to obtain a sensation that the viewer can touch the entire (whole body) of the specific character that appears three-dimensionally on the surface of the dimming member 30. The display control as described above may be reproduced, for example, by changing the parallax setting value in the 3D application related to the three-dimensional display.

Further, on the inner peripheral surface of the housing 10, the region 202 existing in the emission direction of the light emitted by the gesture sensor 63, for example, the region 202 facing the arrangement position of the gesture sensor 63, is the light emitted from the gesture sensor 63 (for example). , Infrared light) may be provided with a member that prevents the gesture sensor 63 from receiving light. By doing so, the amount of light received by the gesture sensor 63 for the light reflected in or around the region 202 is reduced, so that the decrease in sensitivity of the gesture sensor 63 can be further suppressed. Examples of the "member that suppresses light reception by the gesture sensor 63" include a light absorbing member that can absorb the light from the gesture sensor 63, a member that diffusely reflects the light from the gesture sensor 63, and the like. Examples of the "absorbent member" include black paper, a rubber-coated member, and a member made of an infrared absorbing material (infrared antireflection sheet, etc.).

In the display device 1, a predetermined process according to the detection result by the motion detection means (for example, the microphone 61 and the gesture sensor 63) as described above is executed as the motion of the specific character displayed on the image display unit 20. It is good. Such control may be executed, for example, by the control unit 70 described later.

In this way, when the movement of the visual person is detected, the specific character operates according to the detection result, so that the communication between the visual person and the specific character can be reproduced. Such a function of reproducing communication between a visual person and a specific character, or a function of reproducing pseudo communication between a visual person and a specific character is referred to as a "communication function". Therefore, for example, it is possible to provide a highly entertaining display device 1.

For example, when the visual person utters "bye bye", the microphone 61 detects the visual person's voice "bye bye", and the control unit 70 determines the action of a specific character based on the voice recognition result "bye bye". In the display device 1, a specific phrase and an operation corresponding to the specific phrase are associated and registered in advance in a data table or the like. Then, the control unit 70 executes the process corresponding to the determined operation. For example, at least one of a voice output process for outputting the voice of "bye bye" from the speaker 62 and a display output process for displaying and outputting a video in which a specific character is waving to the image display unit 20 is executed. Will be done. In this way, the viewer feels that the specific character displayed on the image display unit 20 has responded to the voice uttered by himself / herself. Therefore, for example, it is possible to provide a highly entertaining display device 1.

Further, for example, when the visual person puts his / her hand in the internal space 100 and waves his / her hand, the gesture sensor 63 detects the visual person's gesture "bye bye", and the control unit 70 detects the gesture detection result "bye bye". Determines the behavior of a particular character. In the display device 1, a specific operation and an operation corresponding to the specific operation are associated and registered in advance in a data table or the like. Then, the control unit 70 executes the process corresponding to the determined operation. For example, similarly to the above, a voice output process for outputting the voice of "bye bye" from the speaker 62 and a display output process for displaying and outputting a video of a specific character waving to the image display unit 20. At least one of them is executed. In this way, the viewer feels that the specific character displayed on the image display unit 20 has responded to the gesture he / she has made. Therefore, for example, it is possible to provide a highly entertaining display device 1.

Further, the display device 1 further includes a motion sensor 64 (see FIG. 6) capable of detecting the presence of a person within a predetermined range (for example, also referred to as a detection target space) with the display device 1 as a reference. .. Examples of the motion sensor 64 include a Doppler sensor (for example, a microwave Doppler sensor) that can detect the presence of an object based on the speed of a moving object and the presence or absence of a Doppler signal.

The motion sensor 64 is arranged near the upper end 51 of the opening 5 toward the front side of the display device 1, and the detection target area of the motion sensor 64 is provided on the front side of the display device 1. .. By doing so, it is possible to more reliably detect that a person is on the front side of the display device 1.

Specifically, the motion sensors 64 are arranged on the front side (front side) in the arrangement area 110 (see FIG. 7) described later at intervals so as not to come into contact with the outer peripheral wall 80 on the front side of the housing 10. ing.

In the display device 1, the display image of the image display unit 20 is controlled to be switched to a three-dimensional image on condition that the motion sensor 64 detects that a person has approached within the predetermined range. It should be done. In other cases, the two-dimensional image may be displayed, or the display image of the image display unit 20 may be hidden. In this way, for example, while a person is in a position where the display object (for example, a specific character) of the image display unit 20 cannot be viewed stereoscopically, the three-dimensional image is not displayed on the image display unit 20 and is displayed. When a person approaches within a range in which an object can be viewed stereoscopically, a three-dimensional image is displayed on the image display unit 20. Therefore, it is possible to prevent a peripheral person from losing interest in the display device 1 due to viewing the display object from a position where the display object cannot be viewed stereoscopically.

[Structure related to the layout space of the control unit]
The display device 1 has a control unit 70. For example, the display device 1 controls the power supply control unit 71 that controls the power supply of the display device 1, the display control unit 72 that controls the display image displayed on the image display unit 20, the control units 71, 72, and the like. It has a plurality of control units 70 including a control unit 73 and the like (see FIG. 7). Note that FIG. 7 is a perspective view illustrating the display device 1 in a state where the upper surface cover portion 12 is removed. In this embodiment, each of the plurality of control units 70 may be mounted on different boards, but two or more control units 70 may be mounted on a single board. Along with this, the arrangement position of each control unit 70 may be changed as appropriate.

As shown in FIG. 5, the housing 10 has an upper surface cover portion 12. Further, as shown in FIG. 6, the housing 10 has a space area 110 between the upper surface cover portion 12 and the upper surface 85 of the inner peripheral surfaces of the housing 10. Then, the control unit 70 is arranged in the space area 110. In this way, maintenance of the control unit 70 that controls the display device 1 can be performed by removing the upper surface cover unit 12 provided on the upper surface of the housing 10. Therefore, the maintainability of the display device 1 can be improved. The space area 110 is also referred to as an accommodation space for accommodating the control unit 70 and the like.

While the control unit 70 is provided on the upper surface portion of the housing 10, the power supply unit 90 of the display device 1 is provided on the lower surface portion 14 of the housing 10 (see FIG. 4B).

The connection cord 91 (see FIG. 7) that connects the power supply unit 90 and the control unit 70 (specifically, the power supply control unit 71) is the outer peripheral wall 80 of the housing 10 (for example, the left wall of the housing 10). ) And the internal space 100, the wiring is made so as to pass through the gap region 89 secured. In this way, the power supply unit 90 can be arranged in an inconspicuous position, and the connection cord 91 for connecting the power supply unit 90 and the control unit 70 can be connected from the outside and the internal space 100 side (opening 5 side). Wiring can be done so that it is not visible to the viewer. Therefore, the design of the display device 1 can be improved. Further, since the power supply unit 90 exists below the internal space 100, the power supply unit 90 can be arranged at a position that is inconspicuous and the position of the center of gravity of the display device 1 can be lowered, so that the posture can be easily stabilized. Can be done.

Further, a ventilation hole 99 (see FIG. 4B) is provided on the bottom surface of the display device 1. The ventilation hole 99 communicates with the space below the internal space. Further, this space is spatially communicated with the space area 110 above the internal space 100 via the gap area 89 in which the connection cord 91 is wired. Therefore, even when the space region 110 is blocked by the upper surface cover portion 12, the heat generated in the space region 100 can be released to the outside through the ventilation holes 99. A vent for releasing the heat generated in the space area 110 to the outside may be provided in the upper surface cover portion 12, and a heat sink or other member for absorbing or radiating heat may be provided in the space area 110 or another place. May be done.

Further, the upper surface cover portion 12 is attached to the main body portion 11 of the housing 10 at a plurality of attachment positions (for example, nine attachment positions 211 to 219). For example, the upper surface cover portion 12 has two mounting positions 211 and 212 on the front side (front side) of the housing 10, and two mounting positions 213 and 214 on the right side of the housing 10. It is attached to the main body 11 of the housing 10 at two mounting positions 215 and 216 on the left side of the housing 10 and at three mounting positions 217 to 219 on the rear side (rear side) of the housing 10.

For example, as shown in FIGS. 7 and 8, at the mounting positions 211 and 212 (an example of the first mounting position) on the front side of the display device 1 among the plurality of mounting positions 211 to 219, the upper surface cover portion 12 And the main body 11 of the housing 10 are connected to each other by using the first fixture at a position inside the outer peripheral wall 80 of the housing 10. Examples of the "first fixture" include a fitting member 95 and a receiving member 96 in which the fitting member 95 is detachably configured. Note that FIG. 8 is a diagram showing the back surface of the upper surface cover portion 12. For example, the fitting member 95 is formed in a convex shape, and the receiving member 96 is formed so that the convex fitting member 95 can be inserted freely.

On the other hand, among the plurality of mounting positions 211 to 219, at the mounting positions 217 to 219 on the back side of the display device 1 (an example of the second mounting position) (see FIG. 7), the main body 11 and the top cover of the housing 10 The portion 12 is connected to the portion 12 at a position outside the outer peripheral wall 80 of the housing 10 by using a second fixture. As the "second fixture", for example, a screw 98 (see FIG. 8) is exemplified.

In this way, at the second mounting position (for example, mounting positions 217 to 219), which is difficult for the eyes to see, the outer peripheral wall 80 of the housing 10 is used by using the second fixing tool (for example, screw 98). The upper surface cover portion 12 and the main body portion 11 are connected from the outside of the above. On the other hand, in the first mounting position (for example, mounting positions 211 and 212) that is easily visible to the visual eye, the first fixture (for example, the fitting member 95 and the receiving member) is located in a place that is difficult for the visual visual to see. 96) is used to connect the upper surface cover portion 12 and the main body portion 11. Therefore, the design of the display device 1 can be improved.

Further, the first fixture (for example, the fitting member 95 and the receiving member 96) can be attached and detached more easily than the second fixture (for example, the screw 98), and the display device can be used by using the first fixture. The maintainability of 1 can be improved. Further, in all the mounting positions 211 to 219, the upper surface cover portion 12 and the main body portion 11 are not connected by using the first fixture, but in a part of the plurality of mounting positions 211 to 219. , The upper surface cover portion 12 and the main body portion 11 are connected by using the second fixture. Therefore, it is possible to prevent the upper surface cover portion 12 from being removed by a third party while improving the maintainability of the display device 1.

In the display device 1 according to the present embodiment, among the plurality of mounting positions 211 to 219, regarding the mounting positions 213 to 216 on the side side of the housing 10, the upper surface is the same as the mounting positions 211 and 212 on the front side. The cover portion 12 and the main body portion 11 of the housing 10 are connected by using the first fixture. However, the present invention is not limited to this, and with respect to the mounting positions 213 to 216 on the side side of the housing 10, the upper surface cover portion 12 and the main body portion 11 of the housing 10 are the same as the mounting positions 217 to 219 on the back side. It may be joined using the fixture of 2.

[Detailed configuration of control unit]
FIG. 9 is a control block diagram of the control unit 70 included in the display device 1 according to the embodiment. As described above, the control unit 70 has a general control unit 73. The integrated control unit 73 is a controller having a CPU 701 that functions as an arithmetic processing device that executes arithmetic processing and the like, and a memory and the like that include a RAM 703 used as a work area and a ROM 702 that stores a control program and the like. Various programs are stored in the ROM 702, and the overall control unit 73 reproduces various functions by executing these programs. For example, a voice recognition application (an application having a voice recognition engine function) for reproducing a dialogue between a user and a character is stored in the ROM 702, and the integrated control unit 73 has various sensors 61, 63, 64. , 65, etc., or by executing the voice recognition application based on an input signal from the GPS receiver 60, etc., the dialogue between the user and the character is reproduced. Further, the integrated control unit 73 (an example of the operation control means) is a display control circuit 704 (for example, a display control unit 72 or the like) that controls an image or the like displayed on the image display unit 20, and a sound output from the speaker 62. It has a voice control circuit 705 that controls the above. Further, the integrated control unit 73 may be connected to other devices (for example, an external voice recognition server (also referred to as a voice recognition engine) (not shown), an external dialogue server (also referred to as a dialogue engine) not shown), and the like. It has a communication control circuit 706 that controls the communication of the above. Further, the integrated control unit 73 controls the power supply state of the display device 1 based on the input signal from the power supply control unit 71 that controls the power supply of the display device 1.

[Characters displayed on the display device]
Here, before explaining the control contents by the integrated control unit 73 of the control unit 70, the characters that can be displayed by the image display unit 20 of the display device 1 will be described with reference to FIGS. 10 to 12.

FIG. 10 is a diagram for explaining the outline of the display device 1 according to the embodiment, and in detail, is a diagram showing a state in which the 3D character 1100 is displayed on the display device 1. The 3D character 1100 is a female character. The display device 1 (specifically, the overall control unit 73) further displays a stage image 2100, which means a stage, under the 3D character 1100. The stage image 2100 shows the magic circle here. A viewer who sees this display can get the impression that the 3D character 1100 is standing on the stage. The colors of the 3D character 1100 and the stage image 2100 are not particularly limited. For example, the skin of the 3D character 1100 is flesh-colored. The hair color and upper body outfit of the 3D character 1100 are relatively pale bluish (eg, light blue), and the ornaments on the knees are darker bluish (eg, blue), skirts and shoes. Is white. The stage image 2100 is a relatively dark blue color (for example, dark light blue). In addition, in FIG. 10 and FIG. 11 described below, a view is shown in which the inside of the housing 10 is viewed from slightly above the front of the display device 1.

FIG. 11 is a diagram for explaining the outline of the display device 1 according to the embodiment, and in detail, is a diagram showing a state in which the 3D character 1200 is displayed on the display device 1. The 3D character 1200 is a cat character. In the case shown in FIG. 11B, the display device 1 displays the stage image 2200, which means a stage, under the 3D character 1200 and the 3D character 1200. In the stage image 2200, here, the character string "Yupiteru" and the character string indicating "Juno" (referred to as "Juno"), which is the name of the 3D character 1200, alternate along the outer circumference of the circular stage. It is written in. The colors of the 3D character 1200 and the stage image 2200 are not particularly limited.

Here, the 3D character 1200 and the stage image 2200 will be described more specifically with reference to FIG. The 3D character 1200 is roughly divided into a character body 1210 and a collar 1220. The character body 1210 is the cat character itself. The character body 1210 includes parts of the body shown in white, such as the glabellar, around the nose and mouth, the abdomen, and the anterior part of the foot. Of the body parts of the character body 1210, the parts shown in light gray are relatively light brownish colors (eg, ocher), for example, the parts above and beside the eyes in the face. This corresponds to the upper part of the torso and the part of the foot other than the front side. Of the body parts of the character body 1210, the parts shown in darker gray are darker brownish colors (for example, brown), and are shown by, for example, thin lines on the face, head, torso, and legs. The striped part corresponds to this. The collar 1220 means a collar displayed at the position of the neck of the character body 1210. The collar 1220 is a reddish color (eg, red). A tag 1221 is attached to the collar 1220 below the face of the character body 1210. The tag 1221 is circular and has a predetermined sign. The sign is a sign in which "●" (a circle filled in the inside) is arranged below the "V" -shaped symbol, and each is marked in a reddish color (for example, red). .. The sign displayed on the tag 1221 may function as a trademark indicating the source of the display device 1. The stage image 2200 is a brownish color as a whole, the circle and the character string are a relatively dark brownish color (for example, brown), and the image imitating the smoke inside the circle is a lighter brownish color (for example, brown). It is ocher).

In FIGS. 10 to 12, the backgrounds of the 3D characters 1100 and 1200 are shown in black, but the background is not limited to pure black, and may be a relatively dark background (for example, black or other dark color). good.

The characters shown in FIGS. 10 to 12 are examples. When the display device 1 displays a humanoid character, the display device 1 is not limited to a female character, and may display a male character (for example, a character 1000 (see FIG. 13)). The display device 1 is a real person (for example, a family member), a real person in the past (for example, a historical person), or a fictitious person character (for example, a character appearing in a work of fiction such as a cartoon or an animation). Etc.) may be displayed. When displaying a non-human animal character, the display device 1 is not limited to a cat character, but is an animal character such as a dog or a hamster that can be bred in a general household, or another animal character such as a horse or a cow. In addition, any of the fictitious animal characters (for example, characters appearing in cartoons, animations, and other fiction works) may be displayed. Further, the display device 1 may display another character having the collar 1220.

The display device 1 (specifically, the integrated control unit 73) moves a part of the character's body or outputs a voice imitating the character's utterance based on the communication function. The communication function is a function that reproduces the communication between the viewer and the character, or a function that reproduces a pseudo communication. In the communication function, the character moves in response to the behavior of the viewer (for example, utterance or body movement). For example, the 3D character 1100 performs actions that reproduce the actions normally performed by humans, such as moving the entire body such as dancing and changing facial expressions (for example, expressing emotions of emotions). For example, the 3D character 1200 makes movements that reproduce the movements normally performed by animals (for example, yawning, moving the tail, walking, etc.). Further, the display device 1 outputs, for example, a singing voice as if the 3D character 1100 is singing in accordance with the operation of the 3D character 1100, or outputs a voice related to a dialogue with a visual viewer. The display device 1 outputs, for example, a voice meaning a cat's bark or a voice related to a dialogue with a visual person in accordance with the operation of the 3D character 1200. Such video and audio output is not limited to the communication function, and may be performed by various functions of the display device 1.

The dialogue with the user in the communication function is reproduced, for example, by the voice recognition application stored in the ROM 702 of the general control unit 73, and the external voice recognition server and the dialogue server described above. For example, when the operation unit 40 is pressed by the user, the overall control unit 73 activates the voice recognition application. This enables voice recognition for dialogue with the character. Then, the voice emitted by the user (also referred to as user voice) is transmitted from the communication control circuit 706 of the general control unit 73 to the voice recognition server, and the voice recognition server executes voice recognition processing for the user voice to perform voice. The recognition result is output. For each character string that can be input, the voice (also referred to as character voice) emitted by the character (for example, 3D character 1100) displayed on the image display unit 20 is registered in advance in the dialogue server in association with each other. Then, the voice recognition result by the voice recognition server (for example, the voice recognition result indicated by the character string) is input to the dialogue server, and the character voice corresponding to the voice recognition result is transmitted from the dialogue server to the display device 1. .. Then, the overall control unit 73 outputs the character voice received from the dialogue server from the speaker 61 of the display device 1. In this way, the response processing to the voice by the user is executed, and the dialogue between the user and the character is reproduced.

<Communication function related to 3D character 1100>
In the following, various controls for reproducing the communication between the 3D character 1100 and the user will be described in order with reference to FIGS. 14 to 20.

<1. Communication function related to odor>
For example, an odor sensor 65 (see FIG. 9) for detecting an odor is provided in the display device 1, and the general control unit 73 outputs a voice corresponding to the detection result by the odor sensor 65 as a character voice of the 3D character 1100. It is good to execute the output operation. The odor sensor 65 may, for example, output a signal that changes according to the intensity of a certain odor, or output a signal that changes according to a component (odor component) contained in the odor. The odor sensor 65 outputs, for example, a signal that changes according to the type of odor. The odor sensor 65 is configured to be able to detect the concentration of a specific odor component (tar, ammonia, alcohol, carbon dioxide, etc.) by using, for example, a deodorizing filter or the like. In this way, the overall control unit 73 can reproduce the communication regarding the odor between the character and the user displayed on the image display unit 20 of the display device 1, and the communication between the character and the user can be reproduced. It is possible to reproduce various communications. The odor sensor 65 may be provided on the outer peripheral surface of the display device 1, for example, on the oblique portion 84 of the housing 10 of the display device 1.

For example, the integrated control unit 73 may execute a voice output operation that outputs a voice corresponding to the type of the detected odor as the character voice of the 3D character 1100. A single sensor capable of identifying a plurality of types of odor components may be configured as an odor sensor, and a plurality of sensors capable of identifying different types of odor components may be configured as an odor sensor. good.

FIG. 14A is a flowchart for reproducing communication related to odor, and FIG. 14B is a diagram showing a voice management table (also referred to as a voice management table) related to odor. The voice management table is stored in, for example, the integrated control unit 73 of the display device 1 or the dialogue server. As shown in FIG. 14 (B), the voice management table mainly contains the odor component for each type of odor component (also referred to as odor substance) that can be detected by the odor sensor 65. The type and the sound (referred to as character sound) emitted by the 3D character 1100 are registered in advance. For example, in the voice management table, the odor of tobacco, which mainly contains tar, is registered in association with tar, and as the character voice when the odor of tobacco is detected, "Tobacco smoking is not good. Words that care about the user's health such as "" are registered.

Then, first, in step S11, the overall control unit 73 determines whether or not the odor component has been detected. For example, when the concentration of the odor component detected by the odor sensor 65 exceeds a predetermined threshold value (reference value) for a specific odor, the general control unit 73 determines that the odor component has been detected. In step S12, the overall control unit 73 determines the type of odor registered in association with the detected odor component in the voice management table. For example, when tar having a concentration exceeding a predetermined threshold value is detected, it is determined that tobacco odor has been detected. Then, the integrated control unit 73 outputs the character voice according to the type of the detected odor from the speaker 62. For example, when it is determined that a cigarette odor is detected, the overall control unit 73 outputs a voice of words that care about the user's health (here, "It is not good to smoke too much") as a character voice. Perform output operations. Other examples include the following. For example, when the concentration of a specific main component contained in a fragrance such as aroma oil or a meal exceeds a predetermined reference value, the general control unit 73 determines that an odor such as a fragrance or a meal has been detected, and is the source of the odor. Outputs the voice asking a question about as a character voice. In addition, when alcohol exceeding a predetermined reference value is detected, the overall control unit 73 determines that an alcohol odor has been detected, and "drinks" or "I've been drinking again, please do not hesitate." Etc. are output as the character voice of the 3D character 1100. Further, when a halitosis component exceeding a predetermined reference value (for example, hydrogen sulfide, methyl mercaptan, dimethyl sulfide, etc.) is detected, the overall control unit 73 determines that the halitosis has been detected and "slightly smells. , "Are you brushing your teeth?" Or "Please be careful of alveolar pyorrhea" is output as the character voice of the 3D character 1100. In addition, when an odor component contained in gas fuel such as tertiary butyl mercaptan, dimethyl sulfide, or tetrahydrothiophene is detected, the general control unit 73 determines that the odor of gas fuel has been detected, and says, "It smells like gas. The sound such as "!" Is output as the character sound of the 3D character 1100.

In this way, the overall control unit 73 may execute control to output the voice corresponding to the type of the detected odor as the character voice of the 3D character 1100. By performing such control, the range of communication between the character displayed on the image display unit 20 and the user can be widened, and the user's attachment to the character can be increased.

The display device 1 is not limited to specifying the voice to be output based on the voice management table. The display device 1 may specify the voice to be output according to a scenario in which the utterance content of the character changes based on the content of the past dialogue (history of dialogue), for example. This scenario may define a branching scenario in which data specifying the voice output by the character is managed in a tree structure.

Here, the voice output operation of the voice according to the detection result by the odor sensor 65 is illustrated, but the present invention is not limited to this, and the character performs the movement according to the detection result by the odor sensor 65 in the integrated control unit 73. A display output operation for displaying an image on the image display unit 20 may be executed. For example, similarly to the voice management table, a display management table (not shown) is provided in advance, and the overall control unit 73 displays an image in which the 3D character 1100 moves according to the type of detected odor. It is advisable to execute the display output operation to be displayed in. The display management table may be, for example, a table in which data defining the 3D character 1100 is registered in association with the odor component and the type of odor. The data that defines the 3D character 1100 may be data that indicates an image of the 3D character 1100 to be displayed, or data that defines the content of the movement of the 3D character 1100. For example, when some odor component is detected, the overall control unit 73 may display an image of the 3D character 1100 performing the odor-sniffing movement on the image display unit 20. Further, when the integrated control unit 73 determines that, for example, the odor of tobacco is detected, it is preferable that the image display unit 20 displays an image of the 3D character 1100 performing a smoke-desired movement. At this time, the overall control unit 73 may display an image imitating smoke on the image display unit 20. Further, the overall control unit 73 may execute both the audio output operation and the display output operation as described above. For example, when some odor component is detected by the odor sensor 65, the general control unit 73 displays an image of the 3D character 1100 performing the odor-sniffing movement on the image display unit 20, such as "smell something". The sound may be output from the speaker 62 as the character sound of the 3D character 1100.

Further, the integrated control unit 73 may control the reaction of the 3D character 1100 so as to change according to the concentration (also referred to as the detection intensity) of the odor component detected by the odor sensor 65. For example, the integrated control unit 73 performs images of a plurality of movements provided in stages according to the concentration of the odor component (for example, "grimacing (making an unpleasant expression)", "sweating cold", etc. Either "pale" or "faint") may be selectively displayed.

The display device 1 is, for example, a smoke sensor for detecting smoke, a camera image (for example, an image taken by the photographing unit 227), or an image of a thermo camera as a method for distinguishing between a cigarette odor and an odor (odor) other than the tobacco odor. In combination with another sensor or the like, it may be possible to detect that the user is smoking.

When the general control unit 73 detects that the user is smoking, the image imitating smoke (smoke appears as mokumoku) is superimposed on the 3D character 1100 (in front of the 3D character 1100). An image that reproduces) may be displayed. At this time, the overall control unit 73 may project the face of the 3D character 1100 forward to raise the face, and make the facial expression look unpleasant. The integrated control unit 73 may display a display in which the degree to which the 3D character 1100 dislikes is changed according to the degree of intimacy between the user and the 3D character 1100. The integrated control unit 73 makes the 3D character 1100 look like, for example, if the intimacy is equal to or higher than a predetermined value, it will be forgiven because it is loved, and if it is less than the predetermined value, the 3D character 1100 has an unpleasant facial expression. And so on. The integrated control unit 73 may specify the intimacy according to, for example, the usage record of the display device 1 by the user (for example, the past usage time and the past dialogue content). The algorithm for identifying intimacy is not limited to this.

<2. Communication function based on user's location information>
Further, for example, it is preferable that the display device 1 has a GPS (Global Positioning System) receiver 60 (see FIG. 9), and the following control is executed based on the user's position information. Here, it is assumed that the display device 1 is a portable type. Then, for example, the integrated control unit 73 acquires the position information of the display device 1 possessed (portable) by the user as the user's own position information based on the signal from the GPS receiver 60, and the acquired position information. It is advisable to execute the following control based on.

For example, it is preferable to control so that the voice corresponding to the stay frequency (also referred to as the visit frequency) in which the user stays at the place specified based on the user's position information is output as the character voice. FIG. 15 is a flowchart for reproducing communication regarding the frequency of stay.

For example, in step S21, the overall control unit 73 determines whether or not the user's position information has been received from the GPS receiver 60. When the user's position information is received, in step S22, the overall control unit 73 has a stay frequency of the user staying at a place specified based on the user's position information being equal to or higher than a predetermined value (for example, "2"). Judge whether or not. The frequency of stay is the number of times the user stays at one place in a predetermined period (for example, one day or one week). For example, the integrated control unit 73 searches and identifies the user's place of stay using a network or the like based on the position information (for example, the user's current position information) acquired from the GPS receiver 60. Then, the integrated control unit 73 calculates the stay frequency of the user based on the number of stays of the user at the specified place, and determines whether or not the stay frequency of the user is equal to or higher than a predetermined value. For example, when the user's stay frequency is equal to or higher than a predetermined value, in step S23, the overall control unit 73 controls so that a predetermined character voice registered in advance regarding the user's stay frequency is output from the speaker 62. For example, when the user goes to the same place twice on the same day, the overall control unit 73 determines that the frequency of stay of the user is equal to or higher than a predetermined value, and character voice such as "Oh, I went there a while ago". Is output.

Further, the overall control unit 73 may control to output the voice corresponding to the location specified based on the acquired position information as the character voice of the 3D character 1100. FIG. 16A is a flowchart for reproducing communication regarding the place of stay, and FIG. 16B is a diagram showing a voice management table of character voices regarding the place of stay.

For example, in step S31, the overall control unit 73 determines whether or not the user's position information has been received from the GPS receiver 60. When the user's position information is received, in step S32, the overall control unit 73 searches for and identifies the user's place of stay using a network or the like based on the user's position information. Then, in step S33, the overall control unit 73 outputs the character voice corresponding to the specified location from the speaker 62 based on the voice management table of FIG. 16 (B). For example, when the user goes to the supermarket, the general control unit 73 makes a character voice such as "What do you want to make for today's supper?", Or when the user goes to the hospital, "Is it okay? Are you feeling well?" Output character voice such as. In addition, the integrated control unit 73 outputs a character voice such as "I played a lot" when the user goes to the amusement park, for example.

Further, the overall control unit 73 outputs the voice according to the number of stays (also referred to as the number of visits, etc.) that the user stays at the specified location based on the acquired position information as the character voice of the 3D character 1100. It is good to control. FIG. 17A is a flowchart for reproducing communication regarding the number of stays, and FIG. 17B is a diagram showing a voice management table of character voices regarding the number of stays.

Since steps S41 and S42 in FIG. 17A are the same as steps S31 and S32 in FIG. 16A, description thereof will be omitted. In step S43, the overall control unit 73 acquires the number of times the user stays at the place specified in step S42. Then, in step S44, the integrated control unit 73 outputs the character voice according to the number of stays of the user from the speaker 62 based on the voice management table of FIG. 17 (B). The integrated control unit 73 outputs, for example, a character voice such as "I enjoyed the game" when the user goes to a certain game center for the first time. Then, when the user goes to the certain game center again, the overall control unit 73 outputs a character voice such as "I wanted to go again". Further, when the user goes to the certain game center a predetermined number of times or more (for example, 10 times or more), the integrated control unit 73 outputs a character voice such as "I will play the game again".

Further, the overall control unit 73 may control to output the voice according to the staying time of the user at the specified place based on the acquired position information as the character voice of the 3D character 1100. FIG. 18A is a flowchart for reproducing the communication regarding the staying time, and FIG. 18B is a diagram showing a voice management table of the character voice regarding the staying time.

Since steps S51 and S52 in FIG. 18A are the same as steps S31 and S32 in FIG. 16A, description thereof will be omitted. In step S53, the overall control unit 73 acquires the user's staying time at the place specified in step S52. Then, in step S54, the overall control unit 73 outputs the character voice according to the staying time of the user from the speaker 62 based on the voice management table of FIG. 18 (B). For example, when the user stays at the convenience store for less than 5 minutes, the overall control unit 73 outputs a character voice such as "It was early. I'm glad I waited." Further, when the user stays at the convenience store for 5 minutes or more and less than 10 minutes (5 to 10 minutes), the overall control unit 73 outputs a character voice such as "what did you buy?". Further, when the user's staying time at the convenience store exceeds 10 minutes, the overall control unit 73 outputs a character voice such as "It was late. I was worried."

The integrated control unit 73 may perform the above control based on the user's position information acquired by using the GPS receiver 60 or the like. In this way, the user can obtain the feeling that the character has shown a reaction according to his / her own action, and the user's attachment to the character is increased.

In the above, the portable display device 1 is illustrated, but for example, it may be a stationary display device 1. For example, the integrated control unit 73 (specifically, the communication control circuit 706) communicates with the user's smartphone (smartphone equipped with a GPS receiver) or the like, and the location information of the user who is out (smartphone possessed by the user). (Position information of) is acquired. Then, when the user communicates with the 3D character 1100 after returning home or the like, the overall control unit 73 may control so that the above-mentioned operation is executed. The character voice and the content of the movement at this time may be changed as appropriate.

<3. Communication functions related to user behavior patterns>
Further, when it is determined that the user's behavior pattern matches the predetermined behavior pattern, it is preferable to control so that the voice corresponding to the predetermined behavior pattern is output as the character voice of the 3D character 1100. FIG. 19A is a flowchart for reproducing communication related to an action pattern, and FIG. 19B is a diagram showing a voice management table of character voices related to an action pattern.

For example, in the overall control unit 73, the day of the week (for example, Monday to Friday) when the user goes to work, the time of work (for example, 8:30), and the specific route used at the time of work are set as the "behavior pattern at work". It is registered in advance by a user or the like. Then, for example, when the user's position information is received from the GPS receiver 60 (step S61), the overall control unit 73 determines whether the user's action pattern matches the predetermined action pattern based on the user's position information. It is determined whether or not (step S62). For example, when the user passes a specific route at 8:30 on Tuesday, the overall control unit 73 determines that the user's behavior pattern matches the "commuting behavior pattern". Then, in step S63, the overall control unit 73 uses the voice management table of FIG. 19 (B) to associate with the “behavior pattern at work” and the registered voice (for example, “Please do your best at work”. ") Is output from the speaker 62 as the character voice of the 3D character 1100. In this way, the character shows a reaction according to the user's behavior, so that the user's attachment to the character can be increased. It is not essential that a predetermined behavior pattern (for example, a behavior pattern at the time of commuting) is registered in advance by the user. For example, the integrated control unit 73 has a learning function to learn the behavior pattern of the user. By doing so, a predetermined behavior pattern may be registered.

<4. Communication function for detecting suspicious persons>
Further, when it is determined that the person detected in the detection target space is a suspicious person, a predetermined operation may be executed. Then, when the user of the display device 1 is detected after the predetermined operation is executed, the voice related to the detection of the suspicious person may be output as the character voice of the 3D character 1100. FIG. 20 is a flowchart for reproducing the operation related to the detection of a suspicious person.

For example, in the display device 1, a photographing unit (for example, a camera) (not shown) for photographing a viewer (user or the like) is provided on the front side of the display device 1, and the photographing unit (specifically, the photographing unit) is provided. The sensor) may be used as a detection means for detecting the presence of a person in the detection target space. Examples of the “detection target space” include an angle of view range (photographable range) of a photographing unit in a space in which the display device 1 is placed (for example, the user's home). The photographing unit includes, for example, a lens and an image pickup device (for example, a CCD or CMOS), and captures a multicolored image. The lens of the photographing unit is provided at a position where the viewer (particularly the face) can be photographed. For example, the lens of the photographing unit is provided near the center of the upper end portion 51 in the width direction of the display device 1. The photographing unit outputs, for example, an image signal of each color component of R, G, and B to the control unit 70. The integrated control unit 73 processes this image signal to generate a captured image.

The overall control unit 73 monitors the detection target space using the photographing unit (step S71). Then, when the presence of a person is detected in the detection target space, the integrated control unit 73 performs user authentication such as face recognition in step S72, and the detected person is the registered user of the display device 1 in step S73. Judge whether or not. When the integrated control unit 73 determines that the person photographed by the photographing unit is a registered user of the display device 1, for example, the integrated control unit 73 determines that the person is not a suspicious person. On the other hand, when it is determined that the person photographed by the photographing unit is an unregistered user, in step S74, the overall control unit 73 determines that the person is a suspicious person and executes a predetermined operation. Examples of the "predetermined operation" include an operation of starting recording by the photographing unit, an operation of issuing an alarm at a relatively loud volume, an operation of notifying a pre-registered security company, and the like. Alternatively, the "predetermined action" may be an action in which the 3D character 1100 speaks to a suspicious person (for example, "who !? Say the secret word!"). Then, when there is no reply from the person determined to be a suspicious person, or when the password is incorrect, the above-mentioned recording start operation or the like may be executed. When the password is incorrect, the overall control unit 73 outputs a voice such as "No !? Say it again" as the character voice of the 3D character 1100, and when it is determined that the password is incorrect again. , The above recording start operation and the like may be executed. By doing so, for example, a suspicious person can be withdrawn from the detection target space, and crime prevention in the detection target space can be enhanced.

Then, when the user of the display device 1 is detected after the execution of the predetermined operation, the integrated control unit 73 may output the voice related to the detection of the suspicious person as the character voice of the 3D character 1100. Examples of the "voice related to the detection of a suspicious person" include "I was scared". In this way, the user's attachment to the character displayed on the image display unit 20 can be increased.

Further, when the detection target space is monitored by using the display device 1, the following operations may be performed, not limited to the detection of a suspicious person.

For example, the display device 1 may be arranged in the reception space of the company to display the 3D character 1100 as a so-called receptionist. Specifically, when a microwave Doppler sensor (an example of detection means) detects the approach of a person in the detection target space (for example, reception space), the overall control unit 73 says, "Welcome. Which department do you use? It is advisable to output a voice such as "?" As the character voice of the 3D character 1100. Then, the overall control unit 73 may control to make a call to the desired department of the visitor based on the response from the detected person (visitor).

<5. Communication function related to the startup time of display device 1>
Further, the overall control unit 73 communicates with the 3D character 1100 in terms of wording in the character voice according to the activation time (for example, cumulative activation time) of the display device 1 from a predetermined time point (for example, the first activation time). It is good to control so that the contents of are changed. For example, as described below, the overall control unit 73 may control the 3D character 1100 to speak in familiar language to the user as the activation time of the display device 1 becomes longer.

For example, for the various character voices described above, three patterns of character voices, such as honorific tone, language tone that has a friendship with the user, and language tone that has a lover relationship with the user, are registered in the voice management table in advance. It should be done. Then, for example, when the activation time of the display device 1 from a predetermined time point is less than 100 hours, the general control unit 73 selects the honorific character voice among the three patterns of character voices registered in the voice management table. Output. When the activation time is 100 hours or more and less than 1000 hours, the overall control unit 73 has a character with a tone that seems to have a friendship with the user among the three patterns of character voices registered in the voice management table. Output audio. Further, when the activation time exceeds 1000 hours, the overall control unit 73 outputs a character voice having a tone that seems to have a lover relationship with the user among the three patterns of character voices registered in the voice management table.

In this way, the user can feel that the relationship (for example, intimacy) with the character has changed due to the change in the wording of the character with respect to the user himself / herself.

The integrated control unit 73 may be controlled so as to reduce the intimacy of the 3D character 1100 with respect to the user depending on the elapsed time from the previous activation. For example, even if the cumulative start-up time of the display device 1 exceeds 100 hours, when one week has passed since the previous start-up, the overall control unit 73 is not in the same tone as the user. The honorific character voice may be output. In this way, the user comes into contact with the character with as little space as possible in order to maintain intimacy with the character displayed on the image display unit 20, further increasing the attachment to the character. be able to.

Further, the overall control unit 73 outputs a greeting voice such as "Nice to meet you" as a character voice at the time of the first start-up, and a predetermined period (for example, a well-separated period such as one month) has elapsed from the first start-up time. At this point, it is advisable to output a voice indicating an anniversary (for example, "It's been a month since we met") as a character voice. In this way, the attachment to the 3D character 1100 can be further increased.

<6. Communication function by linking with other devices>
Further, for example, in the stationary display device 1, the following operations may be executed in cooperation with other devices. For example, when a user visits a place where a device capable of communicating with the display device 1 (hereinafter referred to as another device) is installed, a control unit (CPU or the like) of the other device moves as described below. , The user may be identified, and information suitable for the user (for example, gourmet information or event information) may be automatically guided. For example, a face image of a user who uses a system for linking a display device with another device and a display device (for example, an IP address) owned by the user are associated with each other and registered in advance in an external server or the like. When a person is detected by a sensor provided in the photographing unit provided in the other device, for example, the control unit of the other device includes the face image of the person detected in the photographed image and the user registered in the external server. The user of the display device 1 is identified by comparing with the face image of. Then, the control unit of the other device identifies the display device 1 (for example, the IP address of the display device 1) registered in association with the user on the external server, and the user of the display device 1 is detected. Information indicating that the fact is transmitted to the display device 1. "Information suitable for the user" (for example, gourmet information and event information) is registered in advance in the integrated control unit 73 of the display device 1, and the integrated control unit 73 responds to signal reception from the other device. Then, the registered "information suitable for the user" is transmitted to the other device. Then, the control unit of the other device outputs (for example, voice output) "information suitable for the user" received from the display device 1. In addition, when guiding "information suitable for the user", the other device may display the 3D character 1100 on its display screen. Further, it is preferable that the information or the like guided to the user is transmitted from the other device to the display device 1 and stored as user information in the integrated control unit 73 of the display device 1. Then, for example, when the display device 1 is installed at the user's home, when the user's return home is detected, the overall control unit 73 makes a voice such as "You went to **, how was it?" It is preferable to output it as the character voice of the 3D character 1100. In this way, the user's attachment to the character displayed on the image display unit 20 can be increased.

<7. About other communication functions ＞
Further, the following control may be performed based on the detection results by various sensors.

For example, a wind detecting means (for example, a wind sensor) capable of detecting wind (for example, wind speed) is provided near the lower end portion 52 of the opening 5 of the display device 1, and is as follows based on the detection result by the wind sensor. Control may be performed. The wind may be artificially generated by, for example, the wind generated by moving a part of the body such as waving toward the display device 1 or the wind generated by blowing breath (breath). It is good to say. For example, when a wind with a wind speed equal to or higher than a predetermined value is detected by the wind sensor, the general control unit 73 determines the hair (for example, hair) or clothes (for example, hair) of the character (for example, 3D character 1100) displayed on the image display unit 20. For example, it is preferable to display and output an image in which the skirt) is fluttering. Further, for example, when an image of a lit candle is displayed on the image display unit 20, when the wind is detected by the wind sensor, the overall control unit 73 may switch to an image in which the candle is extinguished. .. Further, when the detected wind is stronger than the predetermined threshold value (the wind speed is larger than the predetermined threshold value), the clothes of the 3D character 1100 flutter more, and the control unit 73 determines the detected wind intensity (for example, , Wind speed), it is good to switch the image.

Further, for example, an object detecting means (for example, an ultrasonic sensor) capable of detecting the presence / absence (presence / absence) of an object and the distance to the object is inside the housing 10 on the inner peripheral surface of the housing 10 of the display device 1. It may be installed facing the side, and the following control may be performed based on the detection result by the ultrasonic sensor. For example, when the general control unit 73 determines that the 3D character 1100 that is stereoscopically displayed in the housing 10 is touched by the viewer's hand based on the detection result by the ultrasonic sensor, the 3D character 1100 determines that the 3D character 1100 is touching. It is advisable to display and output an image showing the reaction. Further, the overall control unit 73 may display and control the 3D character 1100 so as to show a different reaction depending on the part touched by the viewer. The part touched by the observer in the 3D character 1100 may be, for example, a part of the body exemplified by the head, chest, abdomen, buttocks, legs, or the like. Further, the portion of the 3D character 1100 that is touched by the observer may be the clothes (for example, clothes, skirt) or decoration (for example, accessories) of the 3D character 1100.

Further, for example, an earthquake detection means (for example, a seismic sensor) capable of detecting an earthquake and measuring a seismic intensity is provided in the display device 1, and when the general control unit 73 detects an earthquake by the seismic sensor, an earthquake occurs. You should issue an alarm.

Further, for example, a weather sensor capable of measuring the weather may be provided in the display device 1, and the integrated control unit 73 may notify a change in the weather, a weather forecast, or the like based on the measurement result by the weather sensor. The weather sensor may include, for example, a barometric pressure sensor, a temperature sensor, and a humidity sensor, and may be configured to be capable of measuring the weather based on the detection results of each sensor.

Further, the integrated control unit 73 changes the facial expression and movement (also referred to as motion) of the character displayed on the image display unit 20 according to the temperature and / or the humidity detected by the temperature sensor. It is good to display the image.

Further, the integrated control unit 73 receives the facial expression and movement of the character displayed on the image display unit 20 according to the detection result (for example, the distance between the display device 1 and the viewer) by a human sensor such as a microwave Doppler sensor. It is good to display an image in which is changing.

In addition, the integrated control unit 73 may use the humidity sensor to determine whether or not the user has blown. Further, the integrated control unit 73 may also use the temperature sensor to determine the type of breath blown by the user. It is preferable that these sensors are provided near the lower end portion 52 of the opening portion 5 of the display device 1, for example.

Here, there are two types of breaths blown by the user, for example, a breath blown with "fu" and a breath blown with "har". In general, when a cold breath is blown, the person blows quickly with "fu". Therefore, the breath blown with "fu" is referred to as "cold breath" here. In general, when a warm breath is blown, the breath is slowly blown with "har", so here, the breath blown with "har" is referred to as "warm breath".

Regarding these two types of breath, the inventor of the present application obtained the following findings through experiments and the like. Specifically, first, regarding humidity, when a temperature / humidity sensor (for example, a sensor in which a temperature sensor and a humidity sensor are integrated) is separated from the temperature / humidity sensor by a predetermined degree, a breath is blown toward the temperature / humidity sensor. Immediately after that, the measurement result was obtained that the humidity rises sharply from the steady state. After that, the humidity increased monotonically while breathing, and when the breathing was stopped, it took several tens of seconds to return to the original steady state. Similar measurement results were obtained when a breath was blown toward the temperature / humidity sensor under the same conditions. On the other hand, regarding the temperature, it is measured that when you blow "Fu", the temperature drops slightly from the steady state or becomes almost flat, and when you blow "Har", the temperature rises. Results were obtained. The breath that the user blows on the display device 1 is an example of the wind that hits the display device 1.

In consideration of such knowledge and the like, for example, in the display device 1 provided with the humidity sensor, when the humidity sensor detects that the humidity has risen sharply from the steady state, the integrated control unit 73 causes the viewer. It is good to judge (also called a decision) that the breath was blown by. Further, when the monotonous increase in humidity is no longer detected after that, the overall control unit 73 may determine that the blowing of breath has been stopped. Alternatively, when a predetermined time (for example, the time normally required for exhaling (for example, about 3 seconds)) elapses after the sudden rise in humidity is detected, the integrated control unit 73 detects the humidity at that time. Regardless of the result, it is good to judge that the breathing has stopped.

Further, when the humidity sensor detects a sudden rise in humidity and the temperature sensor detects that the temperature has risen from the steady state (for example, at almost the same timing), the integrated control unit 73 tells the viewer. It is advisable to judge that the type of breath blown by is "warm breath". On the contrary, when the humidity sensor detects a sudden rise in humidity and the temperature sensor detects that the temperature has not changed from the steady state or has fallen from the steady state, the integrated control unit 73 , It is advisable to judge that the type of breath blown by the viewer is "cold breath".

Then, the overall control unit 73 may output the video or sound corresponding to the detection of the blowing of breath as the movement of the character displayed on the image display unit 20 or the character sound. Further, the overall control unit 73 may output a video or sound according to the type of breath blown as a character movement or character sound displayed on the image display unit 20. For example, when the type of breath blown by the viewer is "cold breath", the overall control unit 73 displays and outputs an image of the character's clothes fluttering, and the type of breath blown by the viewer is "". In the case of "warm breath", it is advisable to display and output an image in which the character moves to avoid breathing.

In addition, the inventor of the present application has also obtained the following findings using various gas sensors. Specifically, when a breath is blown toward the gas sensor at a predetermined position (for example, about 10 cm) away from the gas sensor, the output value of the gas sensor drops immediately after that, and immediately after the breath is finished. The measurement result was obtained that the output value of the gas sensor started to increase. On the contrary, the measurement result shows that when a breath is blown toward the gas sensor, the output value of the gas sensor rises immediately after that, and when the breath is finished, the output value of the gas sensor starts to fall immediately after that. was gotten. Further, for example, when the wind sent from the blower (for example, a fan) hits the gas sensor, the output value of the gas sensor decreases, and when the wind from the fan does not hit the gas sensor, the output value of the gas sensor increases. Was done.

In consideration of such knowledge, the integrated control unit 73, for example, in the display device 1 provided with the gas sensor, when the output value of the gas sensor suddenly drops from the steady state, the type of breath blown by the visual operator. Should be judged to be "cold breath". On the contrary, when the output value of the gas sensor rises sharply from the steady state, the overall control unit 73 may determine that the type of breath blown by the visual operator is "warm breath".

It is also possible to use a wind sensor to detect breath. According to the wind sensor, the inventor of the present application may be able to catch a relatively weak wind as high as a piece of paper, peaks as soon as the wind sensor is blown, and has good responsiveness when the wind starts to blow. It was confirmed. However, if you keep breathing, it will fall off the peak immediately. A strong wind like a fluffy breath may cool the heater and take some time to recover.

In relation to the configuration in which breath is detected using a wind sensor, the following configuration may be used.

When the integrated control unit 73 continuously detects a predetermined air volume by the wind sensor, it is preferable to perform processing in a direction other than the state in which breath is being blown. The process in the direction in which the breath is not blown is, for example, the process of determining that the breath is not blown. In this case, the integrated control unit 73 processes the direction in which the wind is being blown when the time from the start to the end of the wind detection by the wind sensor is within the time during which the breath can be blown. It is good to do.

In this case, the wind sensor may be a sensor that detects the wind by electrically measuring the heat taken away by receiving the wind. In this sensor, the wind received by the sensor corresponds to the amount of air blown by the sensor. This sensor is set so that when the wind received by the sensor lasts for a time corresponding to the time when the breath is blown, it drops to a value less than the actual air volume during the duration, and the wind received by the sensor. However, when the air volume is smaller than the air volume blown by the breath, it is preferable that the setting is made so that this dip is unlikely to occur.

In the display device 1, as the wind sensor, a flow path for inflowing wind having a common breath inflow path may be provided for a plurality of wind sensors. The flow path may be configured so that wind enters different wind sensors at a predetermined ratio other than 1: 1. The overall control unit 73 may determine the size and time of breathing based on the ratio and the difference in the characteristics of the plurality of wind sensors. The display device 1 includes a plurality of wind sensors having different timings of dropping to a value smaller than the actual air volume during the duration, and the overall control unit 73 blows a large amount of breath based on the outputs of the plurality of wind sensors. It is good to judge the time and time. The display device 1 may include at least a wind sensor other than a gas sensor and a cas sensor as the plurality of wind sensors.

Further, it is preferable to use a gas sensor for detecting a predetermined gas as the wind sensor. As the wind sensor, a gas sensor for detecting a predetermined gas, which is provided with a heater, may be used. In this case, the gas sensor provided with the heater outputs in the direction in which the amount of gas detected increases when the degree of breath blowing is relatively small (as a result of detecting the gas contained in the breath), while the breath When the degree of spraying is relatively large (by cooling the heater with the wind of breath), it is preferable to use a gas having a characteristic of outputting in a direction in which the detected amount of gas becomes small.

When the general control unit 73 determines that breath is being blown, when the strength is relatively large (for example, when the air volume is equal to or higher than the threshold value), an animation for moving clothes, hair, etc. of the 3D character 1100 is performed. On the other hand, when the strength is relatively small, it is preferable to display an animation different from the animation of moving the clothes, hair, etc. of the 3D character 1100.

By the way, when a gas sensor is used for breath detection, the gas sensor outputs the above output value in response to a component (for example, carbon dioxide) contained in human breath. The reason why the output value of the gas sensor is different between the case where the breath "Fu" is blown and the case where the breath "Har" is blown is that when the breath "Fu" is blown, it is sprayed. The speed of the breath is high and it is easy to diffuse to the surroundings immediately after colliding with the gas sensor, while when the breath "Har" is blown, the speed of the blown breath is low and even after colliding with the gas sensor. It is thought that the components of breath tend to stay in the field.

Further, the integrated control unit 73 may also use, for example, the humidity detection result by the humidity sensor to determine whether the detected wind is due to the blow of breath by the visual eye or due to the blower. .. For example, in the display device 1, when the humidity sensor detects that the output value of the gas sensor suddenly drops from the steady state and the humidity rises sharply from the steady state, the integrated control unit 73 breathes by the user. It is good to judge that was sprayed. On the other hand, when the output value of the gas sensor drops sharply from the steady state but the humidity remains in the steady state, the overall control unit 73 may determine that the wind is being sent by the blower. Further, the integrated control unit 73 may also use the temperature detection result of the temperature sensor to determine the type of breath when it is determined that the user has blown. Further, when the output value of the gas sensor is repeatedly increased and decreased within a relatively short fixed period, the overall control unit 73 may determine that the wind of the swinging fan is hitting.

The wind sensor, humidity sensor, temperature sensor, temperature / humidity sensor, and gas sensor used for detecting the wind are examples of the wind detecting means. The display device 1 may have a barometric pressure sensor as a sensor for detecting wind. This is because changes in atmospheric pressure can occur depending on the generation of wind and its strength.

Various controls as described above can be executed. The above control is not limited to the 3D character 1100, and may be performed for a communication function related to another character (for example, the 3D character 1200).

[Display example of 3D image, etc.]
In the display device 1 having the above configuration, the following display may be performed on a three-dimensional image (particularly, a three-dimensional image displaying a 3D character). The following display may be executed as an example of the above-mentioned "communication function", for example. The following display may be reproduced, for example, by the integrated control unit 73 executing the 3D application in the ROM 702.

For example, although not shown, the overall control unit 73 may change the perspective of the character (also referred to as a perspective image) when a part of the character's body is moving. In this way, the character can be given a sense of dynamism.

For example, although not shown, when the character gets angry due to the conversation between the character and the viewer and the character punches out, the general control unit 73 moves the character's hand to the front side of the camera in the 3D application. It is advisable to control the camera position so that the image can be seen, and to change the perspective to a state in which the perspective is emphasized more than the normal state, at least during the punching period. Then, the overall control unit 73 may control the perspective to return to the normal state when the punching of the character is completed.

In addition, when adjusting the distance between the left and right cameras (for example, the distance setting value in a 3D application) so that the 3D character appears to protrude in front of the dimming member 30 in autostereoscopic viewing, if the degree of protrusion is increased, There is a problem that the 3D character appears to be extended in the front-back direction. In consideration of such a problem, it is preferable that the overall control unit 73 performs image processing so as to crush the front-back direction of the 3D character as the pop-out condition is increased (for example, as the distance between the left and right cameras is widened). In particular, it is preferable that the crushing amount is provided according to the degree of popping out, and the crushing amount increases as the 3D character pops out to the front side.

Further, although not shown, it is preferable that the overall control unit 73 displays the 3D character so that various parts of the body (for example, the chest in the case of a female character) sway. In this case, in order to further emphasize the stereoscopic effect of the 3D character, for example, it is preferable to display an image in which the 3D character faces diagonally forward instead of the front.

Further, when the overall control unit 73 sets various parameters (degree of camera separation, orientation, distance to the display object, etc.) in the 3D application to appropriate values according to the character displayed on the image display unit 20. good. In addition to the automatic setting by the integrated control unit 73, a physical slider capable of adjusting various parameters in the above 3D application is provided in the housing 10, and the viewer or the like can adjust various parameters while looking at the 3D character. May be made easy.

Further, although not shown, it is preferable that the overall control unit 73 displays a predetermined object (for example, a plate or the like) so as to be drawn at the same position as the dimming member 30. By doing so, it is possible to inform the visual viewer of the existence of the dimming member 30 by an image, and when the visual viewer puts his / her hand in the space region 102 (FIG. 6), the visual eye's hand It is possible to suppress the collision with the dimming member 30. It is more preferable that the display device 1 is provided with a function of calibrating various parameters so that the predetermined object and the dimming member 30 are at the same position.

In addition, an image in which the 3D character protrudes to the front side (opening 5 side) of the dimming member 30 and a state in which the 3D character protrudes only to the rear side (image display unit 20 side) of the dimming member 30. It is advisable to provide a video of the above in advance so that different actions can be performed in each state. For example, although not shown, when the general control unit 73 displays an image in which the 3D character jumps out to the front side on the image display unit 20, the 3D character asks for a handshake, and is positive to the viewer. It is preferable to display the image of the 3D character performing the action of touching the 3D character on the image display unit 20. In the opposite case, it is preferable to display an image that does not perform such an operation. Further, for example, the overall control unit 73 may display an image of the slide on the surface of the dimming member 30 arranged at an angle, and draw an image in which the character slides on the slide (front side).

Further, the overall control unit 73 selectively displays any one of a plurality of images including the first image and the second image described below as an image recognized as a three-dimensional image on the image display unit 20. It may be. The first image is an image that can be stereoscopically viewed by a viewer so that at least a part of the 3D character 1000 is on the front side (opening 5 side) of the dimming member 30 (3D character 1000 in FIG. 21 (B)). See). The second image may be an image that is recognized to exist on the front side or the back side of the first image. For example, in the image display unit 20, the viewer so that the 3D character 1000 (an example of a “display object stereoscopically viewed by the viewer”) is located behind the dimming member 30 (on the image display unit 20 side). The second image (see FIG. 21 (A)) that can be viewed stereoscopically by the image and the portion above the foot of the 3D character 1000 are visually observed so as to be on the front side (opening 5 side) of the dimming member 30. It is preferable that the first image (see FIG. 21B) that can be viewed stereoscopically is switched and displayed by a person. The first image may be an image that can be viewed stereoscopically by a viewer so that the entire portion of the 3D character 1000 is located in front of the dimming member 30. In this way, any one of a plurality of images including the first image and the second image having different positions recognized as having an image recognized as a three-dimensional image by the viewer is selectively displayed. Therefore, it is possible to change the three-dimensional effect given to the viewer. As a result, for example, the viewer can be more entertained. The image itself of the 3D character 1000 is displayed on the display surface of the image display unit 20, and in FIG. 13, the 3D character that is stereoscopically viewed by the viewer (also expressed as popping out from the image display unit 20). 1000 is shown.

For example, from the image (see FIG. 21 (A)) in which the 3D character 1000 protrudes only to the rear side of the dimming member 30, the general control unit 73 can see the 3D character 1000 (all or a part of the 3D character 1000). It is preferable to switch the display image of the image display unit 20 by transitioning to an image (see FIG. 21B) in a state of protruding to the front side of the dimming member 30. The position where the three-dimensional image is recognized may be switchable by an operation of the operation unit 40 by a viewer or another operation. The viewer may operate so that the image is displayed at a position where the three-dimensional image can be seen three-dimensionally. Moreover, the switchable position of the three-dimensional image may be three or more types. This is because whether or not a three-dimensional image looks three-dimensional depends on individual differences.

Further, when the display is shifted between the first image and the second image, the overall control unit 73 causes the 3D character 1000 to move from the rear side to the front side of the dimming member 30 (or the dimming member 30). An image (video) of a moving process that gradually moves (from the front side to the rear side) may be displayed.

At the time of such an image transition, the integrated control unit 73 may display, for example, an image on the image display unit 20 in which the 3D character performs an action indicating the existence of the dimming member 30. For example, when a 3D character hits the dimming member 30 from the rear side position of the dimming member 30, an image with a hole is placed at the same position as the dimming member 30, and the 3D character pops out from the hole and is in front of the dimming member 30. It is good to display an image that moves to the side.

[Specific example of the image displayed on the display device 1]
Next, a specific example of the image displayed on the display device 1 will be described with reference to FIGS. 22 to 36. 22 to 36 are diagrams showing an example of a character (a video including the 3D character 1200 described with reference to FIGS. 11 and 12) displayed on the display device 1 according to the present embodiment. Each of the images shown in FIGS. 22 to 36 is an image displayed on the display device 1 and visible to the visual eye through the opening 5. Although the stage image 2200 is displayed in FIGS. 22 to 36, the 3D character 1200 may be displayed without displaying the stage image 2200.

The display device 1 (specifically, the integrated control unit 73) regularly or randomly displays the images of the 3D character 1200 shown in FIGS. 22 to 28 during the period of waiting for the movement of the viewer based on the communication function. Switch and display. The display device 1 (specifically, the integrated control unit 73) changes the display of the 3D character 1200 based on the communication function. For example, as shown in FIG. 22 (A), the 3D character 1200 is displayed in a standing posture facing the front side (the side for viewing the image) of the display device 1. The display device 1 may use this posture as a basic posture and display a period during which communication based on the communication function is not performed. For example, as shown in FIG. 22 (B), the 3D character 1200 behaves like licking its own forefoot. For example, as shown in FIGS. 22 (C) and 23 (A), the 3D character 1200 behaves as if looking at its left and right alternately. For example, as shown in FIG. 23 (B), the 3D character 1200 operates toward the ground. For example, as shown in FIG. 23C, the 3D character 1200 behaves as if it were sitting and stretching. For example, as shown in FIG. 24 (A), the 3D character 1200 behaves as if looking into the ground. Further, for example, as shown in FIGS. 24 (B) and 24 (C), the 3D character 1200 walks to the front side. For example, as shown in FIG. 25 (A), the 3D character 1200 behaves as if looking into its own abdomen. For example, as shown in FIG. 25 (B), the 3D character 1200 has an action of tilting its head. For example, as shown in FIG. 25 (C), the 3D character 1200 makes an action of rubbing its own eyes. For example, as shown in FIG. 26 (A), the 3D character 1200 yawns. For example, as shown in FIG. 26 (B), the 3D character 1200 performs an action of licking its own forefoot while sitting. For example, as shown in FIG. 26C, the 3D character 1200 behaves as if looking to the left front of itself. For example, as shown in FIG. 27 (A), the 3D character 1200 behaves as if looking forward to the right of itself. As shown in FIG. 27 (B), the 3D character 1200 operates to stretch. For example, as shown in FIG. 27 (C), the 3D character 1200 behaves as if looking into the ground. For example, as shown in FIG. 28 (A), the 3D character 1200 faces diagonally forward to the right of the display device 1, and then faces the front as shown in FIG. 28 (B). As shown in FIG. 28 (C), the 3D character 1200 performs an action of licking its own forefoot.

29 to 36 are examples of the display of the 3D character 1200 performed by the display device 1 (specifically, the integrated control unit 73) based on the communication function during the dialogue processing. The character strings shown in FIGS. 29 to 36 are character strings that can be recognized by voice recognition and are displayed above the 3D character 1200. FIG. 29A is displayed when the display device 1 recognizes the visual utterance of "Come on", and the voice is output in response to this. 29 (B) to 30 (B) are displayed when the display device 1 recognizes the visual utterance of "sitting", and the voice is output in response to this. FIG. 30C is displayed when the display device 1 recognizes a visual utterance of "I wonder if I am hungry", and a voice is output in response to this. FIG. 31A is displayed when the display device 1 recognizes a visual utterance of "around", and a voice is output in response to this. 31 (B) and 31 (C) are displayed when the display device 1 recognizes the visual utterance of "It's snack time", and the voice is output in response to this. FIG. 32A is displayed when the display device 1 recognizes a visual utterance of "hand", and a voice is output in response to this. 32 (B) to 33 (B) are displayed when the display device 1 recognizes the visual utterance of "it's cute", and the voice is output in response to this. FIG. 33C is displayed when the display device 1 recognizes the visual utterance of "hello", and the voice is output in response to this. FIG. 34A is displayed when the display device 1 recognizes the visual utterance of "eating rice", and the voice is output in response to this. FIGS. 34 (B) and 34 (C) are displayed when the display device 1 recognizes a visual utterance of "a girl", and a voice is output in response to this. FIG. 35A is displayed when the display device 1 recognizes the visual utterance of "wait", and the voice is output in response to this. FIG. 35B is displayed when the display device 1 recognizes the visual utterance of "good boy", and the voice is output in response to this. 35 (C) and 36 are displayed when the display device 1 recognizes the visual utterance of "Yuno", and the voice is output in response to this.

<More detailed explanation of 3D character 1200>
The 3D character 1200 described with reference to FIGS. 22 to 36 will be described in more detail. In the following description, the description in which the display device 1 is the processing subject may be the processing performed by the control unit 70 (more specifically, the overall control unit 73). It is particularly preferable that the 3D character 1200 is drawn in about 3 life forms. It was found that the sense of depth was particularly emphasized in this way. The display device 1 is a 3D character so that the head occupies a height of about one-third, the torso one-third, and the legs one-third in the vertical direction when viewed from the side surface side (horizontal side). It is good to draw 1200. The display device 1 may draw the 3D character 1200 so that the head occupies about one-third and the body occupies two-thirds in the left-right direction when viewed from the side surface side except for the tail.

The display device 1 has a function of drawing a mutual displacement between a state in which the tail cannot be seen and a state in which the tail can be seen in a state where the face is in front, and a state in which the tail cannot be seen during the time when the tail is visible. It should be shorter than the time of. The tail will be drawn on the back side of the head, but sometimes you can see the tail and you can feel a big three-dimensional effect, and you can always feel the three-dimensional effect so that your eyes and head get tired. Can be prevented. In particular, the display device 1 may perform such drawing processing in the standby state for voice recognition. The display device 1 may have a function of drawing so that the tail appears from the top portion of the head when the tail is displaced so as to be visible. In this way, the eyes of the face usually have the eyes of the viewer, and the tail suddenly pops out from the upper center of the eyes to the upper part of the head, which can give surprise and fun.

The display device 1 may be provided with a flat portion in front view on the top of the head of the 3D character 1200, and in particular, the head portion between the left and right ears may be drawn flat in front view. In this way, a three-dimensional tail suddenly appears above the head from the top of a flat head with a weak three-dimensional effect, which can give more surprise and fun. Further, the display device 1 may draw so that the tail appears from above, and then move the portion near the tip of the tail. In this way, the viewpoint can be concentrated on the tail portion on the back side of the face, and a more three-dimensional effect can be felt. Similarly, the display device 1 may draw so that the tails appear from the left and right sides of the body. When the tail appears from the left and right, the display device 1 may shorten the length and / or the time at which the tail appears as compared with the case where the tail appears from overhead. When the display device 1 is made to appear from the left and right, it is preferable to perform drawing in which the display device 1 is made to appear flickering. The display device 1 may draw a drawing that moves the line of sight to the back side from time to time, and can give a more three-dimensional effect. The display device 1 may draw the tail appearing from above the head while recognizing the voice, while the tail appears from either the left or right direction when outputting the voice from the cat. The display device 1 may be provided with a portion of the tail having a drawing mode different from that of other portions at predetermined intervals in the length direction. For example, a pattern having a predetermined width may be formed on the cylindrical surface of the tail at regular intervals in an annular or arc shape. In this way, the inventors have found that the movement of the tail feels more dynamic in three-dimensional space.

The display device 1 performs drawing that changes the current posture to the same posture when there is a change in the state during voice recognition from the state during voice recognition so that the posture is the same during voice recognition. It is good. The display device 1 may utter "Talking Nya" before the start of voice recognition. The display device 1 may be provided with a function of detecting the movement of the visual eye (for example, a sensor or a switch), and may have a function of uttering "what?" When the movement of the visual visual is detected. Both functions should be executed continuously in the form of "What?" And "Talking Nya", and then processed so that they enter the voice recognition state.

The display device 1 is provided with information on words and phrases with complimented contents such as "cute" as words and phrases for voice recognition, and when the words and phrases with complimented contents are recognized, it is preferable to change the posture of the body. It is even better to move the position of the cat itself, such as walking further. In this way, the viewer will be able to take complimenting behaviors and behaviors in order to see the changes in the cat's posture and movements, and the excellent effects of therapy such as improvement of behaviors and behaviors can be obtained.

The display device 1 is provided with a speech recognition phrase corresponding to feeding rice, and when the phrase is recognized, it is preferable to perform drawing in which the tail is swung faster than in other cases. In this way, it is possible to give the viewer a feeling that the cat is actually alive.

In the display device 1, the outer shell of the cat's eyes may be substantially circular, and the black eye portion may be drawn as a vertically long elliptical shape. In the display device 1, the black eye portion may be drawn with a gradation of light and shade in the vertical direction, and the black eye portion may be drawn in a brighter color as it goes downward. The display device 1 may be provided with a black portion at the center of the black eye rather than the periphery of a generally circular or elliptical shape. The display device 1 may draw by providing a crescent-shaped or half-moon-shaped white region along the outer edge of the black eye on the outer portion of the face above the black eye portion. On the other hand, the display device 1 may draw by providing a circular white region at a position near the center of the face below the black eye. The display device 1 may continue to draw the white area even if the position of the 3D character 1200 changes (change in posture, etc.) or the position of the camera or light changes. Usually, highlights are often added by calculation as reflections of lights and the like. However, by doing this, it is possible to emphasize the individuality of the cat in the most visible part of the voice recognition when talking, and impress as a unique cat in a short time while performing voice recognition. be able to.

The display device 1 takes a state in which the face is facing the front and a state in which the face is facing downward. When the face is facing the front, the outer shell of the eye is drawn in a substantially circular shape, while the face is downward. It is advisable to draw the eyes in a horizontally long oval shape when facing.

The display device 1 takes a state in which the upper end of the face is above the upper end of the torso and a state in which the upper end of the face is below the upper end of the torso. The outer shell is drawn in a generally circular shape, while the eyes are drawn in a horizontally long oval shape when the upper end of the face is below the upper end of the torso. The display device 1 has a function of drawing a state in which the mouth is opened and yawning, and it is preferable to draw with the eyes closed at the time of drawing.

The display device 1 may prepare a plurality of patterns of standby motions for the 3D character 1200, and repeat the process of selecting and drawing one pattern from these patterns. The standby motions include licking the legs, stroking the face with hands, licking the buttocks, facing the front, looking left and right, licking the ground, stretching, yawning, and so on. There is a walking motion and so on.

The display device 1 may draw the ears so that the ears move behind the movement of the face. For example, it is advisable to draw the ears so that they remain in position for a while even when the face starts to move. The display device 1 may have a function of simultaneously performing a motion of swinging the tail left and right when performing a licking motion.
The display device 1 may have a body pattern that is asymmetrical when the 3D character 1200 is viewed from the front. In this way, it becomes easier to remember as a unique cat, and it becomes easier to distinguish whether the right side is visible or the left side is visible. This is especially useful when setting up a scene in which the entire image of the 3D character 1200 cannot be seen. In particular, the pattern may be a calico cat pattern, and particularly a tabby cat pattern. The inventors have found that this makes it particularly easy to grasp the three-dimensional effect. In particular, the overhead pattern may be provided in the front-rear direction, while the body pattern may be provided in the vertical direction, and the directions of the patterns may be different. In this way, it becomes easier to recognize that the position of the camera or the cat has changed, regardless of the direction in which the camera or cat is moved.

The display device 1 may have a function of emitting a cry of "Nya", and the cry of "Nya" may be provided with a plurality of intonations, and different motions may be associated with each of the calls. The intonation should include an interrogative intonation, and the motion should include a motion of tilting the head.

<Communication function related to 3D character 1200>
The communication function related to the 3D character 1200 is supplemented. By doing the following, it is possible to provide the viewer with a higher quality communication function with the 3D character 1200. Here, the outline of the behavior of the person to be tamed and the behavior story with the 3D character 1200 will be described. In this embodiment, a photographing unit for photographing a viewer is provided on the front side of the display device 1.

(1) First step: Stage until tame Normally, cats such as stray cats run away just by looking at a person, or there are various types of cats that run away when a person approaches. At that time, the behavior of the cat seems to escape while looking back at the person's appearance many times. Here, when the control unit 70 recognizes the presence of the viewer based on the captured image captured by the photographing unit and the intensity of the microwave measured by the motion sensor 64 exceeds the threshold value, the 3D character Display an image in which the 1200 operates as if it escapes. This is because it is considered that a person has approached the cat. The reason why the photographing unit recognizes the viewer is to show the viewer the scene where the 3D character 1200 escapes. That is, the 3D character 1200 does not escape unless the viewer approaches the display device 1 from the front side.

Next, it is thought that a person calls out to the cat, such as "squat (drop the eye position)" or "come, come". At that time, some cats stop and watch. However, when a person approaches, the cat runs away. This is repeated several times. It is thought that cats are not accustomed to the behavior of such people. Therefore, the control unit 70 has a microwave intensity measured by the motion sensor 64 that is below a certain threshold while the 3D character 1200 is displaying the escaped image, and the 3D character, for example, "come". When the word indicating that the 1200 is called is recognized by voice, an image in which the 3D character 1200 stops is displayed. Here, the condition that the intensity of the microwave is equal to or less than the threshold value is because it is assumed that a human being stops.

Next, it is conceivable that a person feeds a stopped cat. However, when a person approaches a cat, the cat runs away, so it is thought that there is no choice but to put food in a place where the cat often comes. Therefore, the display device 1 has a function of displaying an image in which food is placed in the image display space. For example, when the control unit 70 receives a predetermined operation (for example, an operation of the operation unit 41 or the operation unit 42), or when the gesture sensor 63 detects a predetermined gesture instructing the bait to be placed. Assuming that the food has been placed, the image showing the food is displayed in the image. In this way, the viewer will, for example, place food daily. At this time, the control unit 70 may display the 3D character 1200 as if it were watching the situation from a distance. The control unit 70 uses the motion sensor 64 to display an image of the 3D character 1200 eating food when the presence of the viewer is not recognized and the viewer is not photographed by the photographing unit. Here, the situation where a cat does not eat food in front of a person is reproduced. From the point of view of the viewer, the food is empty before you know it. The control unit 70 counts the number of times the visual eye is fed and stores this. Although this state continues for a while, the control unit 70 may display the distance between the viewer, the 3D character 1200, and the person (the distance felt by the viewer) gradually depending on the number of times the food is fed. For example, the control unit 70 may start feeding and display the 3D character 1200 in a larger size with the number of times of feeding to reproduce that the distance has been shortened (that is, a little accustomed). Further, when the number of feedings increases and reaches a predetermined threshold value, it is assumed that the cat has become accustomed to it, and even if the viewer is looking at the character, that is, the control unit 70 uses the motion sensor 64. Even when the presence of the viewer is recognized and the viewer is photographed by the photographing unit, the image of the 3D character 1200 eating food is displayed. Only then can the viewer see the 3D character 1200 eating food.

However, it is not uncommon for people to not know when a cat will eat. Therefore, the control unit 70 determines a time zone in which the 3D character 1200 eats food (instead of this, it may be a time of a temporary point), and displays an image of eating food in the 3D character 1200 in that time zone. You may let me. This is to remind the viewer that he seems to eat food during this time. When the control unit 70 detects that the viewer tries to touch the 3D character 1200, the control unit 70 causes the 3D character 1200 to output a voice of the predetermined utterance content "Shah" or "Shah Shah", and the 3D character 1200 escapes. Display the image. When the viewer touches the 3D character 1200, the intensity of the microwave detected by the motion sensor 64 exceeds the threshold value when the 3D character 1200 is eating food, or the third It is preferable that the sensor 2331 is identified by detecting a predetermined gesture.

Although such a situation continues for a while, it is preferable that the control unit 70 gradually shortens the distance at which the viewer's hand can be brought close to the 3D character 1200. When approaching a predetermined distance, the control unit 70 may display an image of grooming and relaxing movements in public, assuming that the 3D character 1200 has become accustomed to the viewer. Specifically, the control unit 70 raises the threshold value for the intensity of the microwave, or raises the threshold value for the distance from the display device 1 when the gesture is performed. In this way, the control unit 70 lowers the detection sensitivity, slows down the reaction of the 3D character 1200 to the movement of the viewer, and prevents the utterance of "shah" or "shah shah".

Cats are always vigilant, but they add actions such as grooming, lying down, sharpening their claws, and wiping their faces. As cats become more and more accustomed to people and their hands, they become able to touch them with their hands. Therefore, the control unit 70 may not reflect the detection result of the microwave by the motion sensor 64 in the operation of the 3D character 1200. The control unit 70 may make the first sensor 2331 function as a motion sensor to display an image that makes the 3D character 1200 feel comfortable when it is stroked according to the detection results of gestures in the up / down / left / right and front / back directions of the viewer. The control unit 70 may further recognize the voice of the viewer with the microphone 61 and display an image in which the 3D character 1200 reacts to the voice. For example, the control unit 70 may make a cry of "nya" as the utterance content regardless of what kind of words are recognized.

The control unit 70 may further display an image in which the 3D character 1200 begs for food as time passes. The control unit 70 determines the time zone (for example, morning, noon, and evening) when the photographing unit recognizes the presence of the viewer and the motion sensor 64 detects the presence of the viewer. It is advisable to make a cry of "meow meow" and display an image of the action of rubbing the face. Further, the control unit 70 may reproduce how the 3D character 1200 remembers its own name when the viewer calls out to the 3D character 1200. For example, the control unit 70 may respond only to the word "Yuno" and make a cry of "Nya", or may respond to the voices of "Yuno" and "It's bait" and spoil it. It's a good idea to display a video that encourages you to take action or rubs happily.

(2) Second step: The stage of memorizing the language (Japanese) When the control unit 70 recognizes the visual voice of "Yuno" at a certain time, the control unit 70 makes a voice indicating a response of "what?" Output. From here, the 3D character 1200 will learn the words. The control unit 70 counts the number of times of being called, takes a cumulative average / day, and calculates a value calculated by the cumulative average of the number of times of feeding / day × the cumulative average of the number of times of being called × a random coefficient ( The response is based on the following (referred to as "cumulative average value"). This voice is a predetermined voice such as "Good morning", "Hello", "Good evening", "How are you?", "Do you want food?" The control unit 70 stops responding (that is, reproduces that the 3D character 1200 has forgotten a word) or increases the number of responding words according to the cumulative average value. For example, the control unit 70 may reduce the number of responding words as the cumulative average value is smaller, and increase the number of responding words as the cumulative average value is larger. The cumulative average value is calculated based on the number of times the display device 1 has been called from the start of use to the present time, but the number of times the call has been made from the time when the display device 1 has been called back to the present time by a predetermined period in the past. It may be calculated based on. The predetermined period may be fixedly determined, such as one month, or if the display device 1 has not been used for a certain period of time, it may be a period after that period when the use is started. Since the cumulative average value can change significantly at the beginning of the use of the display device 1, for example, if the viewer does not speak even once a day, the 3D character 1200 may stop responding. However, as the number of calls increases, the cumulative average value does not change significantly. In this way, it is possible to reproduce how the 3D character 1200 takes time to forget the words. The random coefficient used to calculate the cumulative average value is a value for reproducing the whims of a cat, and may be called a whimsical coefficient. The random coefficient is the 3D character 1200 and visual observation, such as giving / not feeding when the character 1200 asks for food, and taking actions such as calling out or touching when the 3D character 1200 is sleeping. It is good to change it according to the behavior of the person.

When the cumulative average value exceeds a certain threshold value, the control unit 70 may further talk to the viewer from the 3D character 1200 or respond to a question regarding predetermined information such as weather and news. Of course, if the number of times the viewer feeds is reduced, the cumulative average value is reduced, so that the control unit 70 reduces the types of this response or stops responding. In other words, if the viewer's feeding method is sloppy, or if he / she does not speak properly, the function of the 3D character 1200 to respond will not be maintained, or even if it is maintained, it will not respond due to "capriciousness". In some cases, as described above, it is possible to provide the viewer with a higher quality communication function with the 3D character 1200.

Further, the following may be performed.

For example, in a lenticular display, the image may not be seen three-dimensionally even if the eye position is moved to the right or left by a few centimeters from the position where the image looks three-dimensional. In this case, the viewer may give up as "the image cannot be seen three-dimensionally". In consideration of this point, the control unit 70 is instructed, for example, based on the detection result of the motion sensor 64, "when I look like two people, try moving another 3 cm to the right". It may be controlled to. In this way, it is possible to prevent people from getting bored because they do not look three-dimensional. The instruction may be output by voice from the speaker 62, for example. Further, the timing of issuing the instruction may be the timing at which the motion sensor 64 recognizes that the state in which there is no person in the vicinity of the display device 1 has changed to the state in which there is a person. Further, the timing of issuing the instruction may be the timing at which an unregistered person is recognized, and may be a regular timing.

Further, for example, when the display device 1 can execute physical calculations related to the movements of each of a plurality of parts of the character, when the specific parts (for example, the chest) of the character are relatively small, the movements of the specific parts are related. It is good to prevent physics operations from being executed.

Further, it is preferable that the motion is added to the character's body, but the motion is not added to the character's clothes, and the clothes are controlled to be moved by a physical calculation according to the movement of the character's body. In this way, the amount of calculation in the physical calculation can be reduced.

Further, for example, the control unit 70 may display an object on the image display unit 20 to indicate whether or not voice recognition is in progress. For example, it is preferable that the image display unit 20 controls the display so that the image imitating the lamp lights up only during voice recognition. The object is displayed, for example, inconspicuously (with relatively inconspicuous brightness, color, shape, size, etc.) at the edge of the display area of the image display unit 20 on the back side of the specific character. It is good.

Further, for example, the control unit 70 displays the words (sentences) recognized by the voice recognition on the viewer's viewpoint side (front side) of the object of the specific character for a predetermined time after the voice recognition. It is preferable to hide the display after the lapse of the predetermined time (see FIGS. 29 to 35). Then, it is preferable that the character is controlled to speak after the phrase (speech recognition result) is hidden.

Further, when a three-dimensional image in which a character exists is displayed on the stage, the control unit 70 displays a character having a relatively small depth direction (for example, a humanoid character) in the center of the stage. On the other hand, a character having a relatively large depth direction (for example, a cat character) should be displayed in the center of the stage. Further, for example, when a humanoid character is displayed, it is preferable to control the display so as to emphasize the length of the stage itself to give a sense of depth.

Further, when the control unit 70 displays the image of the character at a position other than the center of the stage (for example, the position on the front side), when the image of the character rotating is displayed, the stage also rotates in the same manner as the character. It is good to display the image.

Also, an image of displaying a stage with a shape that is relatively distant in the depth direction and moving the character along the outer edge of the stage inside such a stage (for example, a cat character along the outer edge of a circular stage). (Video of walking) should be displayed.

Also, when making the character walk, it is better not to draw the stage etc. (including the road etc.), but to draw an image in which the character steps on the spot and hardly moves the overall position of the character. .. Then, when the character performs an action other than the walking action, it is preferable that the stage or the like is drawn at the feet of the character.

[Modification example]
Although an example of the embodiment of the present invention has been described above, the present invention is not limited to the above embodiment, and various modifications can be made. For example, the following modification may be implemented.

(1) For example, in the display device 1 according to the above embodiment, it is preferable that a plurality of (for example, two) dimming members 30 are detachably provided. In this way, the brightness and floating feeling of the image displayed on the image display unit 20 can be adjusted without providing a separate adjusting member.

(2) Further, in the display device 1 according to the above embodiment and each modification, in addition to the dimming member 30 (see FIG. 6) inclined with respect to the bottom surface of the housing 10, the bottom surface of the housing 10 Further, a dimming member arranged vertically with respect to the subject may be further provided.

(3) Further, in the above embodiment, the gesture sensor 63 (an example of the behavior detection sensor) is arranged on the inner peripheral surface of the housing 10 toward the inner side of the housing 10 (see FIG. 6). However, it is not limited to this. For example, the gesture sensor 63 (specifically, the detection surface of the gesture sensor 63) may be arranged obliquely forward and downward at the upper part of the opening 5. In this way, even when the gesture by the visual operator is performed outside the opening 5, the gesture can be detected.

(4) Further, for example, in the display device 1 according to the above-described embodiment and each modification, a transmissive display whose transmittance (or transparency) can be adjusted may be further provided. The transmissive display may be provided, for example, in the internal space 100 of the housing 10 on the front side (front side) of the dimming member 30. In particular, it is preferable that the transmissive display is tilted in the same manner as the dimming member 30.

Alternatively, instead of the transmissive display, a film whose transmittance (or transmissivity) can be adjusted may be provided. In this way, it is possible to produce an effect in which the stereoscopically displayed character gradually begins to appear.

(5) Further, in the display device 1 according to the above-described embodiment and each modification, a panel (so-called face-fitting panel) into which the face of the viewer can be fitted is further provided in the vicinity of the opening 5. You may. The panel may be installed at a position where it can be viewed stereoscopically with the naked eye. Alternatively, a picture may be drawn on the housing 10 side of the panel so that the viewer's face is photographed with his / her face fitted in the panel. Then, it is preferable that the captured image is uploaded to the SNS (Social Networking Service) as "you when looking at me".

(6) Also, a naked-eye stereoscopic image that outputs an instruction to close one eye and move the head left and right to a position where the image can be clearly seen (also called clear), and to close one eye and open both eyes at the position where the image can be clearly seen. It is preferable to use a visual display device. Furthermore, if the image looks double when both eyes are opened at a position where one eye is closed and the image can be clearly seen, close one eye again and move to the left or right to clearly see the image. It is preferable to use an autostereoscopic display device that outputs an instruction to open both eyes.

(7) Further, it is preferable that the system includes a printed matter printed with words and phrases that can be recognized by voice by the display device 1 together with the display device 1 according to the above embodiment and each modification. Further, it is preferable to use a system in which a printed matter printed with words and phrases that can be voice-recognized by the display device 1 can be installed in the vicinity of the display device 1 together with the display device 1.

(8) Further, a display device 1 having a built-in voice recognition device and having voice directivity in a specific direction (for example, the front direction) is provided, and the same display device is arranged in the direction opposite to the specific direction. It is good to have a system characterized by this. For example, it is preferable that the two display devices 1 are arranged so that the openings 5 of the two display devices 1 are opposite to each other. In this way, for example, in one display device 1 (specifically, the microphone 61 of the display device 1), the voice of a person using the other display device 1 or the speaker 62 of the other display device 1 can be heard. It is possible to avoid inputting the output voice.

(9) The display method of the image display unit 20 may be a lenticular lens method, a paralux barrier method, or other autostereoscopic method, or a display method that can be recognized as a three-dimensional image using eyeglasses. The housing of the display device 1 may have a rectangular parallelepiped shape, a cubic shape, a cylindrical shape, another polyhedral shape, a spherical shape, or another shape. Further, the shape, structure, dimensions, colors, patterns, arrangements, and the like of each component of the display device 1 described above are merely examples. Further, a part of the components included in the display device 1 described above may be omitted, or another component may be added. The display device 1 may be a stationary display device, but it may also be a portable type, a head-worn type, a spectacles type, or the like that can be worn on the head of a viewer. In such a case, as the dimming member, a common (single) dimming member is arranged on the optical path of the image light of the image viewed by the left eye of the viewer and the image light of the image viewed by the right eye. good. The opening 5 does not have to be square when viewed from the front side, and may be formed in a circular shape or other shape. The image display unit 20 may be an image display unit that uses an organic EL, a digital mirror device, or other display element as the display element. Even if the image display unit 20 is a display device having a light source other than the backlight, if there is a possibility that light leakage from the light source can be visually recognized, floating that can be given to the viewer due to the presence of the dimming member. The feeling can be improved.

(10) The display device 1 may have one or a plurality of image display units other than the image display unit 20. For example, as the second image display unit, a display unit arranged so that the display surface faces upward (for example, vertically upward) may be provided on the entire or a part of the floor of the internal space 100. The second image display unit is, for example, a liquid crystal display, but may be a display unit of another type. The control unit 70 may control the display of one or more image display units other than the image display unit 20. In this case, the stage image may be displayed on the second image display unit, and the 3D character may be displayed on the image display unit 20. In this way, it is possible to produce an effect using an image on the floor of the internal space 100. Further, instead of the second image display unit, the floor may be produced by using a light emitting body (for example, a light emitting diode), a light guide member, and a light shielding member. In this case, a light guide member is arranged on the floor of the internal space 100, and a light shielding member corresponding to a predetermined pattern (for example, a magic circle) is arranged on the light guide member. When the light of the light emitting body is incident on the light guide member, the light is emitted upward from the region of the upper surface of the light guide member where the light shielding member is not arranged, and the visual eye can see this.

(11) In the above embodiment, voice recognition for interacting with the character displayed on the image display unit 20 is enabled in response to the pressing operation of the operation unit 41, but the present invention is not limited to this. For example, when the presence of a person is detected in the detection target area of a motion sensor (an example of a detection means) such as an all-around microwave Doppler sensor, the integrated control unit 73 may enable the voice recognition. good. In this way, when the user interacts with the character displayed on the image display unit 20, for example, it is not necessary to perform an operation for enabling voice recognition or to utter a trigger word, and the user communicates more naturally. Can be reproduced.

At this time, for example, it is preferable that both the voice recognition by the voice recognition application in the display device 1 and the voice recognition by the voice recognition server are enabled. However, as described below, the activation of voice recognition in the voice recognition application in the display device 1 and the activation of voice recognition in the voice recognition server may be executed step by step. For example, when the presence of a person is detected in the detection target area of the human sensor or the like, voice recognition by the voice recognition application in the display device 1 is enabled, and then the voice is spoken or greeted by the visual operator. When detected by the recognition application, speech recognition on the speech recognition server may be enabled.

When the display device 1 is provided with a photographing unit (an example of detection means) such as a camera, a detection target space is provided on the front side (opening 5 side) of the display device 1, and the integrated control unit 73 displays. When the presence of a person is detected on the front side of the device 1, voice recognition may be enabled. In this way, it is possible to enable voice recognition after more reliably determining that the viewer is trying to speak to the character displayed on the image display unit 20.

Further, it is preferable that the overall control unit 73 is configured to enable the voice recognition on condition that the user authentication is successful after the person is detected in the detection target area. The user authentication authentication method may be, for example, an authentication method (face authentication, vocal cord authentication, etc.) that does not require manual operation by the user. In this way, for example, when user authentication is performed for a person other than the registered user registered in the display device 1 and the user authentication fails, voice recognition is not enabled and the image display unit 20 displays the image. Cannot interact with the character being played. Conversely, the character displayed on the image display unit 20 does not respond to a person other than the registered user. As a result, the user's attachment to the character can be increased.

Further, when the voice of the wording other than the wording registered in advance is detected in the display device 1 or the dialogue server mounted on the external server, the voice recognition may not be enabled.

In addition, an odor sensor may be used as a means for enabling voice recognition. For example, the odor of the registered user of the display device 1 may be registered in the display device 1 in advance, and when the odor of the registered user is detected by the odor sensor, voice recognition may be enabled.

Further, even if voice recognition is enabled in this way, for example, the voice of the character (for example, 3D character 1100) displayed on the image display unit 20 is not immediately output, but the voice from the user. If there is no hook, the voice of the character should not be output. For example, the integrated control unit 73 does not immediately output the character voice of "Welcome back" in response to the voice recognition being enabled, but the user with "I'm home" with the voice recognition enabled. It is advisable to output the character voice of "Welcome back" on condition that the voice is detected. Further, for example, in a dialogue system, it is preferable that a branching scenario for reproducing the following dialogue between the viewer and the character (for example, 3D character 1100) is created. For example, on weekdays
User: I'm home Character: Welcome back ~
User: Atchi Character: If the dialogue is reproduced as if you were tired in the hot weather, and if it is a holiday,
User: I'm home Character: Ah, return User: Atchi Character: I didn't complain because I went out all the way in the hot weather User: It's work Work character: I'm sorry if it's true, branching scenario so that the dialogue like thank you for your hard work is reproduced Should have been created.

Further, a branching scenario may be created according to the detection result by the odor sensor. for example,
User: The rice was delicious. Character: "Well, smell it. Kunkun. It smells good!" Or "Hmm !? Isn't it salty? Be careful with your body!"
The dialogue such as may be reproduced.

As another example, when an odor is detected by an odor sensor,
Character: Kunkun, huh? What is this smell?
User: Aroma-fired Character: Oh, you may want to recreate the dialogue that you thought you would relax. If the visual response to the odor type question is not registered in the branch scenario, it is preferable that a voice such as "Wow, that's right!" Is uniformly output as a character voice.

(12) Further, the integrated control unit 73 constantly records, for example, the voice of the latest predetermined time (for example, about 15 seconds), and when the voice of the trigger word for enabling voice recognition is detected, The voice recognition may be enabled. For example, the voice recognition application of the display device 1 may be activated at all times (or in response to a pressing operation of the operation unit 41, etc.), and voice recognition by the voice recognition server may be enabled by detecting a trigger word. At this time, the integrated control unit 73 (specifically, the communication control circuit 706) receives the detected voice (for example, from the detection start time to the detection end time) detected by the microphone 61 (an example of the voice detection means). It is preferable to transmit the voice data of the voice obtained by excluding the voice of the trigger word from the detected voice) to the voice recognition server. For example, suppose that a user voice saying "I'm going to Tokyo tomorrow, but tell me the weather" was detected. Here, the trigger word is "Reitan," which is the nickname of the 3D character 1100. In this case, the general control unit 73 removes the trigger word voice "Reitan" from the detection voice "I'm going to Tokyo tomorrow but tell me the weather" and the voice "I'm going to Tokyo tomorrow but tell me the weather". To the voice recognition server.

Here, for example, if the above-mentioned detection voice "I'm going to Tokyo tomorrow, but tell me the weather" is sent to the voice recognition server as it is, "Rei-tan" is included in the voice recognition result. As a result, the character voice corresponding to the voice recognition result may not be accurately extracted in the dialogue server, and the dialogue with the user may not be engaged. On the other hand, according to the above, even if the trigger word is uttered in the middle of one sentence, the voice data of the voice excluding the trigger word is transmitted to the voice recognition server. Therefore, it is possible to prevent the dialogue with the user from being disengaged due to the voice recognition being performed with the trigger word included in the middle of the sentence.

(13) Further, in reproducing the dialogue between the user and the character displayed on the image display unit 20 in cooperation with the voice recognition server, the following operations are executed according to the configuration of the voice recognition server. May be good.

For example, when the voice recognition server is configured to start the voice recognition process after the reception of the voice data file is completed, the general control unit 73 has the voice detected by the microphone 61 before and after the trigger word. It is advisable to individually send each voice data file of voice to the voice recognition server. For example, among the detected voices from the detection start time to the detection end time, the voice data file of the user voice (also referred to as the user voice of the first half) detected before the voice of the trigger word is the voice of the trigger word. It is preferable that the voice data file of the user voice (also referred to as the user voice in the latter half) detected later is transmitted to the voice recognition server prior to the voice data file.

In this way, the voice recognition server starts the voice recognition process for the user voice in the first half without waiting for the completion of receiving the voice data file of the user voice in the second half. Therefore, the voice recognition process can be performed more efficiently as compared with the case where the voice data file of the voice in which the user voice of the first half portion and the user voice of the second half portion are combined is transmitted to the voice recognition server. As a result, the display device 1 can receive the character voice from the dialogue server earlier, and can shorten the waiting time of the user until the user's voice is responded to.

Further, for example, when the voice recognition server is configured to stream-reproduce the voice data from the display device 1 and execute the voice recognition process in real time, the voice data of the first half is transmitted to the voice recognition server in real time. At that time, it is preferable that the reproduction speed T1 of the user voice in the first half portion is controlled to be faster than the standard reproduction speed T0 (T1> T0). For example, the overall control unit 73 changes the setting so that the user voice of the first half portion is reproduced 25% faster than the standard reproduction speed T0 on the voice recognition server, and transmits the voice data of the first half portion. In this way, in the voice recognition server, the voice recognition process for the user voice in the first half can be completed earlier than in the case where the user voice in the first half is played back at the standard playback speed T0. The voice recognition process for the user voice in the latter half can be started earlier. As a result, the display device 1 can receive the character voice from the dialogue server earlier, and can shorten the waiting time of the user until the user's voice is responded to.

Further, when the voice data of the user voice in the latter half is transmitted to the voice recognition server in real time, the voice reproduction speed T2 in the latter half is faster than the standard playback speed T0 and is higher than the user voice playback speed T1 in the first half. It is also preferable that the speed is controlled so as to be slow (that is, the relationship of T0 <T2 <T1 is satisfied). For example, the overall control unit 73 changes the setting so that the user voice of the latter half portion is reproduced 10% faster than the standard reproduction speed T0 on the voice recognition server, and transmits the voice data of the latter half portion. In this way, both the user voice of the first half portion and the user voice of the second half portion are stream-reproduced faster than the standard reproduction speed T0, and the voice recognition process is executed in the voice recognition server. As a result, the waiting time of the user until the response to the user's voice can be further shortened. On the other hand, the user voice of the latter half portion is reproduced at a speed faster than the standard reproduction speed T0, but slower than the reproduction speed T1 of the user voice of the first half portion. Therefore, it is possible to suppress a decrease in voice recognition accuracy in the voice recognition system. Therefore, the waiting time of the user can be further shortened while suppressing the deterioration of the voice recognition accuracy.

When the voice recognition process is executed in real time by playing a stream of voice data in the voice recognition server, for example, the user voice detected by the microphone 61 is transmitted to the voice recognition server in real time, but the trigger word is used. It is preferable to control so that the voice recognition by the voice recognition server is not started until the voice is detected.
