(Interactive interactive system and terminal device)
FIG. 1 is a logical configuration diagram showing an entire interactive interactive system that enables line-of-sight matching between interlocutors in remote locations. This system realizes a two-way dialogue between a conversation person 3A (first conversation person) at point A (first place) and a conversation person 3B (second conversation person) at point B (second place). System. This system is a system that establishes an intimate relationship of trust even among interlocutors in remote locations and realizes intimate communication. For example, the system can be used as a counseling system or a service providing system for home learning. In that case, at least service providers such as teachers, doctors, and psychologists are assumed as interlocutors, but trust formation is the foundation in general communication and can be widely applied. Therefore, this system has various functions and configurations so that these service providers can provide information necessary for providing the service and an ideal environment.

  Specifically, at point A, (a) a chair 4A (having a height adjustment mechanism 40A) on which a conversation person 3A (for example, a counselor) sits, (b) a table 2A toward which the conversation person 3A is directed, and (c) transmission A terminal device 20A having a mechanism for matching the line of sight between the interlocutors via the means 27 is installed, and the interlocutor 3A is isolated by the partition 22A. On the other hand, at point B, (a) a chair 4B (having a height adjustment mechanism 40B) on which a conversation person 3B (for example, a client who receives counseling) sits, (b) a table 2B to which the conversation person 3B faces, (c) A terminal device 20B having a mechanism for matching the line of sight between the interlocutors via the transmission means 27 is installed, and the interlocutor 3B is isolated by the partition 22B. Here, in order to enable transmission and reception of image information and audio information between the terminal device 20A at the point A and the terminal device 20B at the point B, the transmission unit 27 is configured to use an optical fiber transmission line 31 (main transmission line) and a satellite A communication transmission path 32 (backup transmission path) and the like are included. The transmission means 27 may be either wired or wireless. The transmission means includes a network such as a telephone line network that has already been laid, and further includes an electronic bulletin board system (BBS: Bulletin Board System) provided with various databases.

  At point A, the above-described chair 4A functions to define the position of the interlocutor 3A. The chair 4A is preferably fixed in order to keep the distance from the display unit (display device) 21A of the terminal device 20A constant. However, even if the chair 4A is not fixed, the distance between the chair 4A and the display unit 21A can be kept constant by installing the table 2A on the conversation person 3A and the display unit 21A. (It has been confirmed that the presence of the table 2A is a reference for the psychological distance of the interlocutor 3A). The configuration of the terminal device 20B at the point B where the other party's dialogue person 3B (for example, a person who receives counseling, etc.) is also the same.

  At the point A, the terminal device 20A is arranged on the table 2A, which displays (1) the video of the conversation person 3B based on the image information transmitted from the terminal device 20B at the point B via the transmission means 27. The display unit 21A provided with the monitor 1A, (2) the main body unit 6A for holding the CCD camera (imaging unit) 5A in a predetermined position, and (3) the transmission means 27 from the terminal device 20B at the point B. A voice output unit 23A (speaker) for outputting the voice of the conversation person 3B based on the voice information transmitted through the terminal, and (4) collecting the voice of the conversation person 3A as voice information, and a terminal at the point B A voice input unit 24A (microphone) for transmission toward the apparatus 20B is provided.

The terminal device 20B at the point B is also configured in the same manner as the terminal device 20A at the point A described above. Specifically, the imaging device 600B (camera device) including the display unit 21B, the CCD camera 5B, and the main body unit 6B. ), An audio output unit 23B, an audio input unit 24B, a character graphic input unit 25B, and a video processing device 26B. Here, the CCD camera 5B may be housed in the main body 6B. In this case, the main body 6B also functions as a camera housing.

  Further, the configuration of the camera devices 600A and 600B in the terminal devices 20A and 20B at the points A and B will be described. For convenience of explanation, when referring to components common to the terminal devices 20A and 20B at the points A and B, the characters A and B for distinguishing the points are omitted as in the camera device 600, for example. To explain. Further, unless otherwise explained, it is assumed that the terminal device 20A at the point A is described as a general rule, and the overlapping description of the terminal device 20B at the point B having a common configuration is omitted.

  The camera device 600 includes a CCD camera 5 (5A) that is an imaging unit, and a main body unit 6 (which may be a camera housing including the CCD camera 5) for installing the CCD camera 5 at a predetermined position in a supported state. . The monitor 1 (1A) is placed on the table 2 (2A), and the conversation person 3 (3A) uses the height adjusting mechanism 40 (40A) placed at a distance L (m) from the monitor 1. Sitting in the provided chair 4 (4A). This distance L (LA) is set to 0.5 m or more and 5 m or less, for example. A CCD camera 5 having a width of about 38 mm or less and a length of about 85 mm or less is provided between the conversation person 3 and the monitor 1 to be photographed. Further, the CCD camera 5 is installed so that its imaging direction is directed to the conversation person 3 to be photographed. The video of the conversation person 3 captured by the CCD camera 5 is transmitted as image information to the other conversation person side (transmitted to the terminal device 20B at the point B via the transmission means 27). Depending on the interlocutor, the interval between the display unit 21 and the interlocutor may be slightly shifted. Therefore, in order to cope with such a situation, it is preferable to select a CCD camera 5 having a deep focal depth.

  Next, a specific installation position of the CCD camera 5 will be described with reference to FIG.

  First, the main body 6 (or camera housing) of the camera device 600 is installed on the display unit 21 for displaying the transmitted image of the other conversation person. The switch 210 includes a power switch for turning on / off the monitor 1. The CCD camera 5 is arranged by the main body 6 at a predetermined position in front of the monitor screen 8 on which the transmitted image 9 of the other conversation person 3B is displayed. The monitor screen 8 can be sufficiently used if it is about 4 inches.

  Specifically, the CCD camera 5 is disposed at a position w (cm) ahead of the monitor screen 8 and in the vicinity of the head 9 a of the conversation person image 9 displayed on the monitor screen 8. The central axis of the CCD camera 5 is located at a position h (cm) above the eye position of the conversation person image 9 indicated by a dotted line.

  Thus, since the CCD camera 5 is located in the vicinity of the head above the eye position of the dialogue person image 9 displayed on the screen 8 of the monitor 1, there is no special trouble in the interactive dialogue. For example, the CCD camera 5 is provided at h = about 3 to 4 (cm) above the eye position (position indicated by a dotted line in the figure) of the conversation person image 9 displayed on the screen 8. In the case of a system configuration in which the distance L between them is set to 70 to 80 (cm), the parallax angle can be sufficiently lower than the parallax angle 3 ° which is the detection limit. In other words, if the opponent's eyes (the eyes of the image of the other conversation person 3B displayed on the monitor screen 8) can be clearly seen when the line of sight matches, even if the camera 5 is provided near the head, interactive conversation is possible. It has been confirmed that there is almost no hindrance. If the size of the screen 8 is, for example, about 5 to 17 (inch), it has been confirmed that a good interactive dialogue can be realized. Note that the size of the screen 8 may be larger.

  Further, the parallax angle will be described with reference to FIG. In this specification, the parallax angle refers to the line of sight of the conversation person 3 to be photographed directed to the conversation person image 9 displayed on the monitor screen 8 and the CCD camera 5 as shown in FIG. 3. The angle θ formed by the line of sight of the talker 3 is said. In other words, it means a deviation angle of the installation position of the CCD camera 5 with respect to the line of sight of the conversation person 3. The line-of-sight coincidence here means that the unnaturalness is less than the allowable limit due to the installation position of the CCD camera 5 as reported in Non-Patent Document 1. Quantitatively, as the parallax angle, the horizontal direction is 4.5 ° or less (with respect to the center A of the eye of the conversation person image 9), and the upward direction is 12 ° (with respect to the image center A). The head portion 9b side of the image 9) and the downward direction of 8 ° (the body side of the image 9 with respect to the image center A) are within the line-of-sight matching range. Of course, this parallax angle should be small, and the detection limit is 3 ° or less in the horizontal and vertical directions. Therefore, the area where the CCD camera 5 can be installed is the conical area shown in FIG. In addition, this conical area | region is the center point A of the conversation person image 9 displayed on the eye 30 of the conversation person 3 and the monitor screen 8 (in this embodiment, the center of both eyes of the conversation person image 9 of this conversation person image 9). The line-of-sight matching region 9b on the monitor screen 8 when the predetermined distance L (m) is away from the line of sight 31 of the conversation person 3 connecting the line 3 defined with the center point A) and the eyes of the conversation person 3 30 positions.

  In addition, when the size of the conversation person image 9 displayed on the monitor screen 8 is small, the CCD camera 5 and the conversation person image 9 do not necessarily overlap each other. Rather, the head of the conversation person 9 is hidden behind the CCD camera 5 and is difficult to see. As described above, the line-of-sight condition is that the eyes of the CCD camera 5 and the interlocutor image 9 exist in a region with a parallax angle of 3 °. H). Accordingly, within this range, the line-of-sight matching state is maintained even if the CCD camera 5 and the head of the conversation person image 9 are shifted. For example, adjusting the image display position on the monitor screen 8 or adjusting the support portion of the CCD camera 5 to change the position of the CCD camera 5 itself can be used to shift the conversation person image 9 and the CCD camera 5. Is done.

(Camera fixing jig)
The camera fixing jig according to the present invention can be applied to a camera device prepared for capturing a conversation person image in a terminal device connected via a predetermined transmission means. The present invention can be applied to a bidirectional interactive system that realizes local dialogue. FIG. 5 is an assembly process diagram for explaining the structure of an embodiment of the camera fixing jig according to the present invention.

  As shown in FIG. 5, the camera fixing jig 10 includes a holding unit 100 that holds the camera housing 6 including the CCD camera 5, and a fixing unit that is directly or indirectly installed on the housing surface of the display device 21. 200, and a deformable connecting portion 300 that connects the holding portion 100 and the fixing portion 200. With such a configuration, the camera fixing jig 10 holds the camera housing 6 (main body) including the CCD camera 5 (imaging unit) for capturing an image of an object located in front of the monitor screen 8. Thus, the CCD camera 5 can be freely installed at a predetermined position in front of the monitor screen 8 of the display device 21 or at a position off the monitor screen 8.

  Specifically, the fixing unit 200 has a structure for being directly or indirectly fixed to any surface of the housing of the display device 21 surrounding the monitor screen 8. As this fixing structure, for example, as shown in FIG. 8A, a hook-and-loop fastener (registered trademark: Magic cloth, Velcro) 210 may be attached to the installation surface of the fixing unit 200. Further, as shown in FIG. 8B, the fixing portion 200 may be configured to have a gap 220 by being configured in a U shape. In this case, the camera fixing jig 10 as a whole is held by sandwiching a fixing plate 230 installed in advance in the casing of the display device 21 with a gap 220.

  The holding part 100 includes a first plate 110 having a through hole 112 for fixing one end of the connecting part 300 and a guide hole 111, and a second plate 120 slidable along the longitudinal direction of the first plate. With. One end of the connecting part 300 and the first plate 110 are fixed by a fixing screw 530 through the through hole 112. Further, the fixing plate 510 is screwed to the fastener 520 through the through hole 121 of the second plate 120 and the guide groove 111 of the first plate 110, so that the second plate 120 is attached to the first plate 110. Further, since the fixing screw 510 penetrating the second plate 120 is movable along the guide hole 111 of the first plate 110, the fixing position of the fixing screw 510 is shifted to move the second plate 120 to the first plate 120. It becomes possible to slide along the longitudinal direction of the plate 110.

  In such a holding unit 100, the second plate 120 that directly holds the camera housing 6 is formed by bending one metal plate (see FIG. 6A) at the position of the broken line in FIG. ), A structure having a portion having an urging function is obtained. In the second plate 120, 122 a and 122 b are guide pieces, and when the second plate 120 slides with respect to the first plate 110, the longitudinal direction of the second plate 120 and the longitudinal direction of the first plate 110. It is provided to prevent the direction from shifting. The holding pieces 124 a and 124 b protect the side surface of the camera housing 6 when the holding unit 100 holds the camera housing 6. The front end portions 125 a and 125 b of the holding pieces 124 a and 124 b are bent so as to face the front surface of the camera housing 6 when the holding portion 100 holds the camera housing 6. Further, the second plate 120 is provided with a spring piece 123 as an urging means for pressing the front surface of the camera housing 6 against the tip portions 125a and 125b by pressing the back surface of the camera housing 6. Yes. As described above, the holding structure for fixing the camera housing 6 to the holding unit 100 is configured by the tip portions 125 a and 125 b and the spring pieces 123 in the holding unit 100. In addition, as an elastic pressurizing material which replaces the spring piece 123, a felt, a rubber piece, etc. may be used, for example. This is because the camera casing 6 itself is lightweight and can be easily fixed without damaging the camera casing 6 by using a frictional force.

  The connecting portion 300 has a plurality of joint portions formed by a ball joint having one end fixed to the fixing portion 200 and the other end fixed to the holding portion 100. Specifically, as shown in FIG. 8C, the connecting portion 300 includes a ball joint member 303 having both ends or one end processed into a spherical shape, and a connecting portion in which an end sphere of the ball joint member 303 is accommodated. The member 301 is configured. In particular, a notch 302 is provided at one end of the connecting member 301. Normally, when there is no notch 302, the movable angle of the ball joint member 303 with respect to the connecting portion 301 is limited to θ1, but by providing this notch 302, the movable angle of the ball joint member 303 is θ2 (> θ1). ). As a result, the degree of deformation of the connecting portion 300 can be further improved.

A deformable connecting portion 300 having one end fixed to the fixing portion 200 can be positioned in front of the monitor screen 8 together with the camera housing 6 holding the holding portion 100 fixed to the other end.

  On the other hand, FIG. 9B shows a state in which the camera fixing jig 10 is attached to a thin display such as a notebook personal computer as a display device. Also in this case, the fixing part 200 of the camera fixing jig 10 is installed on the rear surface of the thin display housing via a hook-and-loop fastener. However, if the camera fixing jig 10 is to be installed on such a thin display, the connecting portion 300 is required to have a greater degree of deformation than the attachment shown in FIG. There is a limit to the degree of deformation. Therefore, in order to install the holding unit 100 that holds the camera housing 6 in front of the monitor screen 8 of the thin display, the holding unit 100 holds the camera housing 6 with respect to the first plate 110. By sliding the two plates 120, the CCD camera 5 included in the camera housing 6 is installed in front of the monitor 8 in cooperation with the connecting portion 300.
