For this, the user interaction type image display system of the present embodiment includes a rear screen portion formed to be able to maintain a standing state through the first supporting means 120, (100).

The projector 510 is disposed behind the rear screen unit 100 and is installed to project the projected image on the rear surface of the rear screen unit 100 through the reflecting unit 220. As the reflecting means 220, it is preferable to use a known regular reflection mirror so that image distortion does not occur when the projected image is reflected.

Further, the rear screen unit 100 is provided with audio output means 520 provided to enable audio output synchronized with the image projected on the rear screen unit 100. As the sound output means 520, a known speaker can be applied.

In addition, sensing means (300, 400 or 600) provided to detect a user-related state with respect to a predetermined sensing region on the front side of the rear screen unit 100 are provided.

And computing means for receiving the sensing information of the sensing means (300, 400 or 600) and controlling the image of the person to be projected by the projector (510) based on the sensed information and controlling the sound output 500 are provided. The computing means 500 is electrically connected to the sensing means 300, 400 or 600 via a known control communication line, connected to the projector 510 through a known video output signal line, , A system DB, a system memory, an interface, and the like.

The computing means 500 of the present embodiment includes a sensing information processing module 502 for receiving sensing information of the sensing means 300, 400 or 600 and converting the sensed information into information data for control processing, An image control module 504 for controlling an image projected through the projector 510 (for example, image selection, position, image effect, size adjustment, etc.), and audio output means 520 based on preset control logic A sound output control module 506 for controlling the sound output through the sound output control module 506 (e.g., voice selection, size adjustment, sound effect, etc.), and a management module 508 for performing a setting operation function of the overall system, And a communication module 510 for enabling remote control in cooperation with the means. In addition, an image DB 512 for storing various images (for example, a moving image) file projected through the projector 510 and an audio DB 514 for storing various audio files synchronized with the image are provided.

In the present embodiment, the ultrasonic sensor 400, the depth camera 300, and the image camera 600 may be used as the sensing means 300, 400 or 600, and detailed descriptions will be given later for each sensor.

In addition, at least one video camera 600 installed toward the front side of the rear screen unit 100 may be further provided, and a detailed description of the video camera 600 will be described later.

The user interaction type image display system of this embodiment can be configured as follows from a mechanical viewpoint.

A base portion 200 having a predetermined area is provided. The base portion 200 may be formed of, for example, a metal or synthetic resin sheet, and may be configured to be mounted on the bottom surface of the installation site of the present system. If the rear screen unit 100 can maintain the upright state of the rear screen unit 100 through the first supporting unit 120, the base unit 200 may be deformed into various shapes other than rectangular plate shapes as shown in FIG. 1 or FIG. It is possible.

The rear screen unit 100 is formed of a plate-shaped screen having a real person size and is fixed to the upper front side of the base unit 200 through the first supporting means 120 to maintain an upright state. Here, the actual person size is not necessarily limited to the actual size of the user or the person in the image, but refers to a size implemented with the same or similar size and eye level as the actual person when viewed from the user's point of view.

The first supporting means 120 functions as a support for maintaining the rear screen unit 100 in a substantially upright state on the floor of the installation space and is not particularly limited in its shape, And may be provided at the lower portion of the rear surface of the plate-shaped screen having the actual person size. The first supporting means 120 is not only provided on the upper front side of the base 200 as described above but also formed in the form of an independent support on the floor of the installation space or in a form fixed to a wall surface or a ceiling . From the same viewpoint, the second supporting means 210 and the third supporting means 302, 402 and 602, which will be described later, are not necessarily provided on the base portion 200. However, when the first, second, and third support means are provided on the base portion, they are advantageous over individual installation because they provide a compact installation structure as a whole.

The rear screen is a known screen which is used to project an image to be provided to the user on the opposite side of the user (rear side of the screen) and to be seen through the front side of the screen where the user is located. The rear screen unit 100 may be provided on the rear surface of the acrylic resin panel 110 having the light transmitting property so that the projected image can be clearly seen on the front side, And may be constructed by attaching a coating material 111 thereto.

The projector 510 is installed on the upper part of the base part 200 and is provided on the upper rear side of the base part 200 so as to face the rear screen part 100, And is configured to project an image toward the reflecting means 220.

The second supporting means 210 functions as a support for supporting the base unit 200 to keep the reflecting means 220 at the image projection position, and the shape thereof is not particularly limited.

The sensing means 300, 400 or 600 may be installed on the upper portion of the base portion 200 and may be disposed on the rear portion of the rear screen portion 100 to face the predetermined sensing region on the front side of the rear screen portion 100, Is installed through the third support means (302, 402 or 602) at the side portion position. The third supporting means 302, 402 or 602 functions as a support for supporting the sensing means 300, 400 or 600 at a predetermined height and position, and the shape thereof is not particularly limited.

The voice output means 520 and the computing means 500 may be installed on the upper portion of the base portion 200 and the location and structure of the voice output means 520 and the computing means 500 are not necessarily limited as long as the voice output can be effectively transmitted.

The rear screen unit 100 is preferably formed to have an actual person size in an upright state so that the actual person size in an upright state is included. In the case of the present embodiment, the rear screen unit 100 is preferably formed with an actual person size in an upright state, (Preferably the front side surface) of the rear screen portion 100, and the region corresponding to the upper body of the portrait image is formed in a shape And is implemented using an image projected from the projector 510.

The reason for adopting this configuration is that users tend to take an interest mainly in the face or hand motion of another person in conversation with another person, so that the upper body region of the person who can make various changes realizes real image through the projection image, It is not necessary to provide the projected image necessarily.

In this case, since the projector 510 needs to project only the area corresponding to the upper body of the actual person-size image through the reflecting unit 220, the projector 510 may be shorter than the case of projecting the whole body of the person- It is possible to secure only the projection distance, thereby minimizing the space for installing the reflecting means 220 (e.g., the distance between the projector and the reflecting means, or the distance between the reflecting means and the rear screen portion), and the overall display system becomes compact There is an advantage that it can be.

Meanwhile, the computing means 500 may calculate at least one of an operation, a size, a position, and a direction of a person image projected from the projector 510 based on sensing information of the sensing means 300, 400 or 600 Control is performed.

At least one ultrasonic sensor 400 installed to face the front of the rear screen unit 100 may be used as the sensing means for sensing the presence or absence of a user in the sensing area of the sensor. can do.

At this time, the computing means 500 is configured to control the image projected from the projector 510 based on the presence information of the user sensed by the ultrasonic sensor 400.

For example, when it is detected that the user does not exist in the sensing area of the sensor, the computing means 500 outputs the image and voice in the normal standby state. If the sensing device 500 detects that the user has entered the sensing area of the sensor A conversation image or a gesture image of a person optimized for the greeting for responding to the user and the advertisement or the promotional message to be transmitted is outputted.

As another example, the sensing means may be at least one depth camera 300 installed toward the front side of the rear screen unit 100. As the depth camera used in this embodiment, a known Kinect depth camera can be used. The Kinect depth camera is a camera that analyzes and acquires distance information of a three-dimensional scene from continuously illuminated infrared light. For example, commercial products such as PrimeSense have been commercially available. For example, in a commercial product, a product with a depth resolution of 640 * 480, 30 fps, and an effective distance of 3.5 meters can sense the depth or position of the object with relatively high precision.

The depth camera 300 may sense at least one of the presence of the user and the position of the user in the sensing area. The computing means 500 performs control on the image projected from the projector 510 based on at least one of information on the presence of the user sensed by the depth camera 300 and position information of the user .

When the computing means 500 controls the image projected from the projector 510 based on the presence information of the user sensed by the depth camera 300, Control similar to control can be achieved.

In the case where the computing means 500 controls the image projected by the projector 510 based on the position information of the user sensed by the depth camera 300, more various image control is possible.

In this case, the computing means 500 may be configured to recognize which of a plurality of positional regions the user's position corresponds to, and distinguish the corresponding one of the plurality of positional regions, And stores the matching image.

Accordingly, it is possible to determine in real time which location area of the plurality of location areas the user's location information detected by the depth camera 300 corresponds to, and to provide a matching image for each area stored in the corresponding location area to the projector 510 Respectively. This will be described in more detail with reference to the drawings.

FIG. 3A is a schematic plan view for explaining a concept of setting an area according to a location direction among a user's location area in a user interaction type image display system according to an exemplary embodiment of the present invention.

The predetermined plurality of position areas A, B, C, and D are divided according to the positional direction of the user around the rear screen unit 100 as shown in FIG. 3A, And a plurality of images captured at the same time in each photographing direction corresponding to the position direction.

For example, when a plurality of position areas A, B, C, and D are previously set as shown in FIG. 3A, the computing means 500 includes a plurality of position areas A, B, C, and D And a matching image for each region to be projected by the projector 510 may be stored and provided for each of the plurality of position areas A, B, C, and D. For example, the matching image may be an image of a person who appears in the image and simultaneously images the advertisement or the announcement of the advertisement in the directions of the areas A, B, C, and D.

In such a configuration, for example, when the user is located outside the sensing area and views the image of the rear screen portion while walking in the direction of D -> C -> B -> A, Is continuously matched. As a result, the effect of continuously matching the line of sight of the video person and the line of sight of the user can be obtained, thereby providing a more realistic and dynamic image.

FIG. 3B is a schematic plan view for explaining a concept of setting an area according to a location distance among a user's location area in a user interaction type image display system according to an exemplary embodiment of the present invention.

The predetermined plurality of position areas (a, b, c, and d) are divided according to the positional distance of the user around the rear screen unit 100 as shown in FIG. 3B, At a distance corresponding to the position distance.

For example, when a plurality of location areas a, b, c, and d are set as shown in FIG. 3B, the computing means 500 may store a plurality of location areas a, b, c, and d And a matching image for each region to be projected by the projector 510 can be stored and provided for each of the plurality of position areas a, b, c, and d. For example, the matching image may be an image of a person who appears in the image and simultaneously images the advertisement or the announcement of the advertisement in the positions of the areas a, b, c, and d.

In such a configuration, for example, when the user is located outside the sensing area and views the image of the rear screen portion while walking in the direction d -> c -> b -> a, not only the actual position of the user, As a result, the distance between the video person and the user can be more real and dynamic, and the video can be provided dynamically.

Meanwhile, as another example of controlling the image according to the position distance of the user, the computing means 500 is configured to recognize and recognize which position area of the plurality of position areas the user's position corresponds to, The position areas a, b, c, and d of the rear screen unit 100 are divided according to the position distance of the user around the rear screen unit 100, ) Or zoom-in or zoom-out processing to project the image.

In such a case, a person who appears in the image can obtain a realistic and dynamic image in a form similar to that of the above-described embodiment without simultaneously photographing the image guiding the advertisement or the promotional message at the positions of the respective regions a, b, c, It has the advantage that it can provide.

It is needless to say that the control of the image according to the position direction or the distance as described above is not necessarily performed independently, and the control considering the position direction and the distance may be performed at the same time.

In another embodiment, the computing unit 500 may further include at least one image camera 600 installed toward the front side of the rear screen unit 100, And further control the image projected by the projector 510 based on the face information of the user included in the captured image.

For this purpose, the computing means 500 is configured to be able to determine at least one of the gender or age of the user based on the face of the user included in the photographed image, The matching image for each gender or age to be projected is stored in the memory 510.

In addition, the computing means 500 may further include a sex or age matching image on the basis of the sex or age information of the user determined based on the face of the user included in the photographed image of the image camera 600, Respectively.

The matching image for sex or age is provided in such a manner that a male or female is classified to match a facial expression or a gesture of a character image or a variety of facial expressions or gestures that are advantageous for delivery of an advertisement or a promotion message for each age group are matched . In the case of the audio output provided in synchronism with the image, it is also possible to differentiate between male and female, apply different expressions or expressions of use, and apply different uses such as the use of synonyms for each age group. Various known techniques can be applied to the face recognition, the sex, and the age determination of the user, and a detailed description thereof will be omitted.

Meanwhile, the control of the image through the ultrasonic sensor, the depth camera, and the image camera is not necessarily performed independently, and it is also possible to control the sensing information of the ultrasonic sensor, the depth camera, and the image camera at the same time.

The frame member is preferably formed to have a width of about 3 cm, for example.

When light emitted from the light emitting means 1100 is illuminated in the above-described state, the light emitted from the front panel 150 'and the rear mirror panel 160 is reflected by the front panel 150' An image of the phosphor is infinitely reflected, and a depth feeling much larger than the width of the actual frame member 1200 can be felt. Reference numeral 1102a denotes a virtual image of a light emitter realized through infinite reflection between the front panel 150 'and the rear mirror panel 160. [

Meanwhile, the light emitting unit 1100 may be provided at a position other than the edge of the mirror reflector 1000. For example, a separate inner support member having the same width as the edge member may be provided along the outline of the lower body of the person and attached to the inner support member. In this case, since the light emitting means is provided along the outline of the lower body of the person on the inner side of the light emitting means on the edge side of the mirror reflector 1000, the depth feeling can be expressed more effectively.
