[0020] In another example of the present invention, the rod is installed between the ceiling and floor of a predetermined building, or between the upper beam and lower beam of a predetermined building. [Effects of the Invention]

[0021] The display unit according to the present invention automatically moves up and down along the axial direction of the rod, thereby automatically moving the front panel up and down, and automatically changing the vertical position of the front panel according to the user's preference. The display unit automatically rotates clockwise and counterclockwise around the center of the rear area at a predetermined location on the rod, thereby changing the front panel between a vertically long state (longitudinal) and a horizontally long state (lateral) and automatically changing the front panel between vertical and horizontal orientations according to the user's preference. The display unit automatically revolves clockwise and counterclockwise around the rod, thereby automatically moving the front panel to a position where the user can see it, regardless of the user's position, and making the front panel visible to the user. The display unit can automatically move the front panel to a position that is most convenient for the user, regardless of the user's position, and can position the front panel in a state that is most convenient for the user.

[0022] The display unit is provided with a microphone for collecting the voices of an unspecified number of users, stores an identification voice waveform for identifying the voice of an authorized user using the display unit, collects the voices of an unspecified number of users using the microphone, compares the user voice waveform of the collected voices of the unspecified number of users with the stored identification voice waveform, and if the compared user voice waveform matches the identification voice waveform, determines that the user who made the voice is an authorized user and activates the display unit.The display unit activates the display unit only if the user who made the voice is an authorized user, and does not activate if the user who made the voice is not an authorized user, thereby preventing use of the display unit by anyone other than an authorized user and allowing only authorized users to use the display unit.

[0023] If the compared user voice waveform and the identified voice waveform do not match, the user who made the voice is determined to be an unauthorized user and operation of the display unit is stopped; if the compared user voice waveform and the identified voice waveform match, the user who made the voice is determined to be a legitimate user and operation of the display unit is continued.The display unit continues operation only if the user who made the voice is a legitimate user, and stops operation if it is determined that the user who made the voice is an unauthorized user, so that the display unit cannot be continuously used by unauthorized users and can be continuously used only by legitimate users, thereby preventing unauthorized use of the display unit and protecting the personal information and privacy of legitimate users.

[0024] The display unit is provided with a camera for photographing an object facing the front panel, stores a specific face image of a legitimate user who uses the display unit, photographs face images of an unspecified number of users using the camera, compares the photographed face image with the stored specific face image, and if the compared face image matches the specific face image, determines that the user of the face image is the legitimate user and activates the display unit; the display unit activates only when the user who photographed the face image is the legitimate user, and does not activate when the user who photographed the face image is not the legitimate user, thereby preventing use of the display unit by anyone other than the legitimate user and allowing only the legitimate user to use the display unit.

[0025] If the compared face image does not match the specific face image, the display unit determines that the user of the face image is an unauthorized user and stops operation of the display unit, and if the compared face image matches the specific face image, the display unit determines that the user of the face image is a valid user and continues operation of the display unit.The display unit continues operation only if the user who photographed the face image is a valid user, and stops operation if it is determined that the user who photographed the face image is an unauthorized user, so that the display unit will not continue to be used by unauthorized users and can be continuously used only by valid users, making it possible to prevent unauthorized use of the display unit and to protect the personal information and privacy of valid users.

[0026] When the voice of the authorized user is collected using a microphone, the display unit automatically moves up and down along the axial direction of the rod so that the front panel faces the direction of the authorized user's voice, and the display unit automatically revolves (rotates) clockwise and counterclockwise around the rod so that the front panel faces the direction of the authorized user's voice.When the authorized user simply speaks, the display unit starts operating and the front panel faces the direction of the authorized user's voice, so the front panel automatically moves to a position that is easiest for the authorized user to see, regardless of the authorized user's position, and the display unit itself can create a state that is easiest for the user to see on the front panel.

[0027] When a first message encouraging the authorized user to move up and down or up and down is collected using a microphone, the display unit is automatically moved up and down along the axial direction of the rod in accordance with the first message, and when a second message encouraging the authorized user to rotate (turn) in a clockwise or counterclockwise direction is collected using a microphone, the display unit is automatically rotated in a clockwise or counterclockwise direction at a specified location on the rod in accordance with the second message, and when a third message encouraging the authorized user to revolve (turn) in a clockwise or counterclockwise direction is collected using a microphone, A display unit including an operation stopping means that automatically revolves (rotates) the display unit clockwise or counterclockwise around the rod in accordance with the third message, and that, when a fourth message from the authorized user urging the display unit to stop operating is collected using a microphone, stops the operation of the display unit in accordance with the fourth message.The display unit can move the display unit up or down, or clockwise or counterclockwise, or clockwise or counterclockwise simply by the authorized user speaking, automatically moving the front panel to the most easily viewable position without any effort on the part of the authorized user, and making the front panel most easily viewable.Since the display unit can stop operation of the display unit in accordance with the authorized user's fourth message, it can stop operation of the display unit at the most easily viewable position for the authorized user, making the front panel most easily viewable for the authorized user.

[0028] A display system is provided with a speaker that produces a predetermined sound, receives the dialogue voice of at least one interlocutor who is conversing with an authorized user via a display unit from another server used by the interlocutor via a predetermined network, outputs the received dialogue voice using the speaker, collects the dialogue voice of the authorized user who is conversing with the interlocutor via a microphone, and transmits the collected dialogue voice to the other server used by the interlocutor via the network.The display system transmits the voice data of the authorized user collected by the microphone to the other server of the interlocutor via the network, and receives the voice data of the interlocutor from the other server via the network, thereby obtaining and outputting (displaying) various voice information of the interlocutor from the other server and providing various voice information of the authorized user to the other server, thereby realizing a dialogue between the authorized user and the interlocutor and enabling the exchange of information useful to both parties.

[0029] The display unit uses a variety of requests from the legitimate user from the past to the present and information on a number of interlocutors who can meet those requests as training data, estimates through learning which interlocutors can meet the legitimate user's specific requests, estimates at least one interlocutor who can meet the legitimate user's specific requests by collecting audio via a microphone, accesses other servers used by the estimated interlocutor via a network, and uses a microphone and speaker to realize a dialogue between the legitimate user and the estimated interlocutor.The display unit estimates the interlocutor who is most suitable to meet the legitimate user's requests and realizes a dialogue with that interlocutor, so that the legitimate user can obtain optimal and useful information from the interlocutor, thereby improving the legitimate user's quality of life, such as food, clothing, and shelter.

[0030] The display unit receives a user image of a user who has become available for conversation via a network from another server used by the user during the conversation, outputs the received user image on the front panel, and transmits a user image of the authorized user taken using a camera via the network to another server used by the user during the conversation.The display unit transmits the user image of the authorized user taken using a camera to the other server used by the user during the conversation via the network during the conversation and receives the user image of the user from the other server via the network, thereby enabling bidirectional transmission and reception of user images of the authorized user and the user and the user image of the user to and from the other server, and can obtain and output (display) the user image of the user from the other server and provide the user image of the authorized user to the other server.The display unit allows both parties to see each other's appearances during the conversation and can exchange accurate information while checking their status.

[0031] The display unit uses a variety of requests from the legitimate user from the past to the present and a variety of website information corresponding to those requests as training data, and estimates through learning which websites correspond to the legitimate user's specific requests. It estimates at least one website corresponding to the legitimate user's specific requests, which are collected using a microphone. When a specific website is designated from the estimated websites, it receives the designated website from another server via the network and outputs that website to the front panel. The display unit outputs (displays) a variety of websites corresponding to the legitimate user's requests on the front panel, and when a specific website is designated from those websites, it outputs (displays) that website on the front panel. Therefore, the website desired by the user can be output (displayed) on the front panel using only voice, and the legitimate user can obtain various information that is useful to them by confirming the desired website requested by voice.

[0032] The display unit translates the dialogue speech spoken by the authorized user and the dialogue speech of the interlocutor received from another server via the network into a specified language, transmits the translated voice of the authorized user via the network to another server used by the interlocutor, and outputs the translated voice of the interlocutor using a speaker.Since the display unit translates the dialogue speech of the authorized user and the dialogue speech of the interlocutor into a specified language and outputs the translated voice of the interlocutor using a speaker, it is possible to communicate through dialogue with interlocutors (foreigners) from various countries who speak different languages, and it is possible to convey various useful information to interlocutors in other countries and obtain various useful information from interlocutors in other countries.

[0033] In a display unit in which a rod is installed between the ceiling and floor of a specified building, or between the upper and lower beams of a specified building, the rod extends from the floor surface to the ceiling surface by installing the rod between the ceiling and floor or between the upper and lower beams, and the display unit can be moved up and down from near the floor surface to near the ceiling surface, and the front panel can be positioned in a state that is most easily visible to the user regardless of the height at which the user's line of sight is.

Furthermore, the third intersecting corner 31c where the second end edge 13 and the first side edge 14 intersect extends radially outward from the third imaginary intersecting periphery 31c connecting the second outer peripheral edge 20b of the second extension member 18b and the third outer peripheral edge 20c of the third extension member 18c, and the fourth intersecting corner 31d where the second end edge 13 and the second side edge 15 intersect extends radially outward from the fourth imaginary intersecting periphery 30d connecting the second outer peripheral edge 20b of the second extension member 18b and the fourth outer peripheral edge 20d of the fourth extension member 18d.

[0051] The display unit 10 has first to fourth outer peripheral edges 20a to 20d and first to fourth imaginary intersecting edges 30a to 30d, which form arcs, of the first to fourth extension members 18a to 18d (first to fourth extension portions) that are shaped like an ellipse that is long in the width direction, which surround the front panel 16, and the first to fourth intersecting corner portions 31a to 31d extend radially outward beyond the first to fourth imaginary intersecting edges 30a to 30d that are shaped like an ellipse, so that the first to fourth extension members 18a to 18d give the rectangular front panel 16 decorative or functional beauty that is a combination of a rectangle and an ellipse (circle). The display unit 10 has an excellent aesthetic appearance (aesthetics) with decorative beauty or functional beauty formed by a combination of a rectangle and an oval (circle), and the front panel 16 is well-looking, so that a user who sees the front panel 16 can feel a sense of beauty, and can stimulate the user's desire to try using the display unit 10 (willingness to use), as well as stimulate the user's desire to purchase.

[0052] The rod 11 is installed between a ceiling 32 (ceiling slab) and a floor 33 (floor slab) of a predetermined building (a building made of reinforced concrete, steel reinforced concrete, steel, wood, or the like). The rod 11 may also be installed between an upper beam and a lower beam of a predetermined building (a building made of reinforced concrete, steel reinforced concrete, steel, wood, or the like). The rod 11 is formed from an axial member 34 (axial rod) that extends straight in the vertical direction, and a movable member 35 that is attached to the outer periphery of the axial member 34. The axial member 34 and the movable member 35 are made from metal such as aluminum, steel, alloy, or reinforced plastic.

[0053] In the rod 11, the lower end of the shaft member 34 is connected to the floor 33 (floor slab) by a predetermined connecting means (connecting metal fittings such as bolts, V-bolts, U-bolts, etc.), and the upper end of the shaft member 35 is connected to the ceiling 32 (ceiling slab) by a predetermined connecting means. The shaft member 34 is connected to the ceiling 32 (ceiling slab) and the floor 33 (floor slab) so as to be rotatable in both clockwise and counterclockwise directions. The display unit 10 has a center of its back area 17 connected (installed) to the movable member 35 of the rod 11 (support) by a predetermined connecting means (connecting metal fittings such as connecting bolts, angle members, connecting plates, etc.).

[0055] The shaft member 34 (including the movable member 35) rotates clockwise and counterclockwise by the drive of a first motor installed at the lower end thereof. As the shaft member 34 (including the movable member 35) rotates clockwise and counterclockwise, the display unit 10 (including the first to fourth extension members 18a to 18d) connected to the movable member 35 of the rod 11 (support) automatically revolves (rotates) around the shaft member 34 (rod 11) in the clockwise and counterclockwise directions indicated by arrow C (see FIG. 6).

[0056] The movable member 35 is driven by a linear motor installed on the shaft member 34 to move up and down along the shaft member 34. As the movable member 35 moves up and down and up and down, the display unit 10 (including the first to fourth extension members 18a to 18d) connected to the movable member 35 of the rod 11 (support) automatically moves up and down along the axial direction of the shaft member 34 (rod 11) in the upward and downward directions indicated by arrow A1 and the downward and upward directions indicated by arrow A2 (see FIG. 5). Driven by a second motor installed on the outer circumferential surface of the movable member 35, the display unit 10 (including the first to fourth extension members 18a to 18d) automatically rotates (turns) around the center of the rear area 17 at a predetermined position on the shaft member 34 (rod 11) in the clockwise and counterclockwise directions indicated by arrow D (see FIG. 7).

[0057] The controller (control device) built into the display unit 10 (display system) is a Web application server 37 (virtual server) that is virtualized (formed) in a cloud 36 (cloud computing) on ​​the Internet. The Web application server 37 (controller) is a virtual server that has a virtual CPU or virtual MPU (central processing unit), a virtual main memory, and a virtual cache memory (memory), and runs on an independent operating system (virtual OS), and a large-capacity storage area is generated (formed).

[0064] The authorized user's identification voice waveform (identification voice waveform data) is collected by the microphone 25 of the display unit 10 and stored in a mass storage area of ​​the Web application server 37 through a predetermined registration procedure. The authorized user's specific face image (specific face image data) is captured by the digital camera 24 (camera) of the display unit 10 and stored in a mass storage area of ​​the Web application server 37 through a predetermined registration procedure.

[0065] An example of the procedure for activating (ON) the display unit 10 is as follows: When a user of the display unit 10 moves near the display unit 10 (within a range of 50 to 500 cm from the display unit 10) and positions themselves in front of the front panel 16, the human presence sensor 26 detects the user and transmits a human detection signal to the controller. Furthermore, if the light detection sensor 27 does not detect any light around the display unit 10, it transmits a light non-detection signal to the controller. The controller (Web application server 37 or physical server) that receives the human detection signal from the human presence sensor 26 and the light non-detection signal from the light detection sensor 27 activates (ON) the LED light 28 to illuminate the area in front of the front panel 16 (light activation means) and also outputs (displays) a voice pronunciation message on the front panel 16 of the display unit 10. When the light detection sensor 27 detects light around the display unit 10 and sends a light detection signal to the controller, the controller (Web application server 37 or physical server) outputs (displays) an audio pronunciation message on the front panel 16 of the display unit 10 without activating the LED light 28.

[0066] When a user makes a predetermined sound (voice) (for example, turning on a switch or activating a screen) in accordance with the voice pronunciation message, the voice (voice) made by the user is collected by microphone 25, and the user's voice (voice data) is transmitted from microphone 25 to the controller (voice collection means). The controller (Web application server 37 or physical server) compares the user voice waveform of the voice (voice data) of a user (an unspecified number of users) collected using microphone 25 (collected by the voice collection means) with the identified voice waveform of the voice (voice data) of a legitimate user stored by the voice waveform storage means (voice waveform comparison means).

[0067] If the user voice waveform compared by the voice waveform comparison means matches the identified voice waveform, the controller (Web application server 37 or physical server) determines that the user who uttered the voice (voice) is a valid user and activates the display unit 10 (activation means). If the user voice waveform compared by the voice waveform comparison means does not match the identified voice waveform, the controller (Web application server 37 or physical server) determines that the user who uttered the voice (voice) is an unauthorized user and does not activate the display unit 10.

[0068] The display unit 10 is activated only when the user who has uttered the voice (speech) is a legitimate user, and the display unit 10 is not activated when the user who has uttered the voice is not a legitimate user, so that the use of the display unit 10 by anyone other than a legitimate user can be prevented, and only the legitimate user can use the display unit 10.

[0069] Another example of a procedure for activating (ON) the display unit 10 is as follows: When a user of the display unit 10 moves near the display unit 10 (within a range of 50 to 500 cm from the display unit 10) and positions themselves in front of the front panel 16, the human presence sensor 26 detects the user and transmits a human detection signal to the controller. Furthermore, if the light detection sensor 27 does not detect light around the display unit 10, it transmits a light non-detection signal to the controller. The controller (Web application server 37 or physical server) that receives the human detection signal from the human presence sensor 26 and the light non-detection signal from the light detection sensor 27 activates (ON) the LED light 28 to illuminate the area in front of the front panel 16 (light activation means) and outputs (displays) a face image capture message on the front panel 16 of the display unit 10. When the light detection sensor 27 detects light around the display unit 10 and sends a light detection signal to the controller, the controller (Web application server 37 or physical server) outputs (displays) a face image capture message on the front panel 16 of the display unit 10 without activating the LED lighting 28.

[0070] The facial image of the user is captured by the digital camera 24 (camera) in accordance with a predetermined capturing procedure output (displayed) on the front panel 16, and the facial image (facial image data) of the user (an unspecified number of users) is sent from the camera 24 to the controller (facial image capturing means). The controller (Web application server 37 or physical server) compares the facial image (facial image data) of the user (an unspecified number of users) captured using the camera 24 (captured by the facial image capturing means) with the specific facial image (specific facial image data) stored by the specific facial image storage means (facial image comparison means).

[0071] If the face image (face image data) compared by the face image comparison means matches the specific face image (specific face image data), the controller (Web application server 37 or physical server) determines that the user of the face image is a valid user and starts up the display unit 10 (start-up means). If the face image (face image data) compared by the face image comparison means does not match the specific face image (specific face image data), the controller (Web application server 37 or physical server) determines that the user of the face image is an unauthorized user and does not start up the display unit 10.

[0072] The display unit 10 is activated only when the user whose face image is taken is a legitimate user, and is not activated when the user whose face image is taken is not a legitimate user, so that the use of the display unit 10 by anyone other than a legitimate user can be prevented, and only the legitimate user can use the display unit 10.

[0073] After starting up the display unit 10, if the controller (Web application server 37 or physical server) collects (picks up) the voice of the authorized user using the microphone 25, it operates (moves) the display unit 10 so that the front panel 16 faces the direction of the authorized user's voice. As an example, if the controller (Web application server 37 or physical server) collects the voice of the authorized user from above the front panel 16, it automatically (automatically) moves the display unit 10 up and down along the axial direction of the rod 11 (first up and down movement means), and if the controller (Web application server 37 or physical server) collects the voice of the authorized user from below the front panel 16, it automatically (automatically) moves the display unit 10 up and down along the axial direction of the rod 11 (first up and down movement means).

[0074] As another example, when the controller (Web application server 37 or physical server) collects the voice of an authorized user from the right side of the front panel 16, it automatically (automatically) revolves (rotates) the display unit 10 in a clockwise direction around the rod 11 (first revolution means), and when the controller collects the voice of an authorized user from the left side of the front panel 16, it automatically (automatically) revolves (rotates) the display unit 10 in a counterclockwise direction around the rod 11 (first revolution means).

[0075] As another example, when the controller (Web application server 37 or physical server) collects the voice of an authorized user from above the front panel 16 to the right of the front panel 16, it automatically (automatically) moves the display unit 10 up and down along the axial direction of the rod 11, and also automatically (automatically) revolves (rotates) the display unit 10 clockwise around the rod 11 (first up and down movement means, first revolution means).Furthermore, when the controller collects the voice of an authorized user from below the front panel 16 to the left of the front panel 16, it automatically (automatically) moves the display unit 10 up and down along the axial direction of the rod 11, and also automatically (automatically) revolves (rotates) the display unit 10 counterclockwise around the rod 11 (first up and down movement means, first revolution means).

[0076] The display unit 10 starts to operate (move) when the authorized user simply speaks, and the front panel 16 moves in the direction of the authorized user's voice, so that the front panel 16 automatically moves to a position where the authorized user can see it most easily, regardless of the authorized user's position, and the display unit 10 itself can create a state where the user of the front panel 16 can see it most easily.

[0077] Furthermore, after starting up the display unit 10, the controller (Web application server 37 or physical server) continuously or periodically captures a facial image of the authorized user with the digital camera 24, and operates (moves) the display unit 10 so that the captured image of the authorized user faces (faces) the front panel 16. As one example, if the authorized user moves above the front panel 16 while using the display unit 10, the controller (Web application server 37 or physical server) automatically (automatically) moves the display unit 10 up and down along the axial direction of the rod 11 to track the movement (third up and down movement means), and if the authorized user moves below the front panel 16 while using the display unit 10, the controller automatically (automatically) moves the display unit 10 down and up along the axial direction of the rod 11 to track the movement (third up and down movement means).

[0078] As another example, if an authorized user moves to the right of the front panel 16 while using the display unit 10, the controller (Web application server 37 or physical server) automatically (automatically) revolves (rotates) the display unit 10 clockwise around the rod 11 to track the movement (third revolution means), and if an authorized user moves to the left of the front panel 16 while using the display unit 10, the controller automatically (automatically) revolves (rotates) the display unit 10 counterclockwise around the rod 11 to track the movement (third revolution means).

[0079] As another example, if an authorized user moves above the front panel 16 to the right of the front panel 16 while using the display unit 10, the controller (Web application server 37 or physical server) automatically (automatically) moves the display unit 10 up and down along the axial direction of the rod 11 to track the movement, and automatically (automatically) revolves (rotates) the display unit 10 clockwise around the rod 11 (third up and down movement means, third revolution means). Also, if an authorized user moves below the front panel 16 to the left of the front panel 16 while using the display unit 10, the controller automatically (automatically) moves the display unit 10 up and down along the axial direction of the rod 11 to track the movement, and automatically (automatically) revolves (rotates) the display unit 10 counterclockwise around the rod 11 (third up and down movement means, third revolution means).

[0080] When an authorized user moves up and down or left and right relative to the front panel 16 while using the display unit 10, the display unit 10 automatically moves up and down or revolves (rotates) to follow the movement, so that even if the authorized user changes position, the front panel automatically moves to a position that is most easily viewable for the authorized user, and the display unit 10 itself can create a state that is most easily viewable for the user of the front panel.

[0081] After starting up the display unit 10, the authorized user can freely move (operate) the front panel 16 of the display unit 10 without touching it. As an example of the authorized user automatically moving the front panel 16, the authorized user may emit a first message (up-and-down movement message) near the display unit 10, encouraging the user to move the display unit 10 upward or downward. When the first message (up-and-down movement message) emitted by the authorized user encouraging the user to move the display unit 10 upward or downward using (via) the microphone 25 is collected (picked up), the controller (Web application server 37 or physical server) automatically moves the display unit 10 upward or downward along the axial direction of the rod 11 in accordance with the first message (second up-and-down movement means).

[0082] When the front panel 16 of the display unit 10 moves up or down to the desired position, the authorized user issues a fourth message (stop message) urging the user to stop the up and down movement (operation) of the display unit 10. When the fourth message (stop message) urging the user to stop the up and down movement (operation) of the display unit 10 issued by the authorized user is collected (picked up) using (via) the microphone 25, the controller (Web application server 37 or physical server) stops the up and down movement (operation) of the display unit 10 in accordance with the fourth message (operation stop means).

[0083] Another example of an authorized user automatically moving the front panel 16 is when the authorized user issues a second message (rotation message) near the display unit 10, encouraging the display unit 10 to rotate clockwise or counterclockwise. When the second message (rotation message) issued by the authorized user encouraging the display unit 10 to rotate clockwise or counterclockwise is collected (picked up) using (via) the microphone 25, the controller (Web application server 37 or physical server) automatically rotates the display unit 10 clockwise or counterclockwise at a predetermined location on the rod 11 in accordance with the second message (second rotation means).

[0084] When the front panel 16 of the display unit 10 rotates to the desired position, the authorized user issues a fourth message (stop message) urging the display unit 10 to stop rotating (operating). When the fourth message (stop message) urging the display unit 10 to stop rotating (operating) issued by the authorized user is collected (picked up) using (via) the microphone 25, the controller (Web application server 37 or physical server) stops the rotation (operation) of the display unit 10 in accordance with the fourth message (operation stopping means).

[0085] Another example of an authorized user automatically moving the front panel 16 is when the authorized user emits a third message (revolution message) near the display unit 10, urging the display unit 10 to rotate clockwise or counterclockwise. When the third message (revolution message) emitted by the authorized user urging the display unit 10 to rotate clockwise or counterclockwise is collected (picked up) using (via) the microphone 25, the controller (Web application server 37 or physical server) automatically revolves the display unit 10 clockwise or counterclockwise along the direction of rotation of the rod 11 in accordance with the third message (second revolution means).

[0086] When the front panel 16 of the display unit 10 has revolved to the desired position, the authorized user issues a fourth message (stop message) urging the display unit 10 to stop revolving (operating). When the fourth message (stop message) urging the display unit 10 to stop revolving (operating) issued by the authorized user is collected (picked up) using (via) the microphone 25, the controller (Web application server 37 or physical server) stops the revolving (operating) of the display unit 10 in accordance with the fourth message (operation stopping means).

[0087] The display unit 10 can be moved up or down, or clockwise or counterclockwise, or right or left, simply by the authorized user speaking (speaking), and the authorized user can automatically move the front panel 16 to the most easily viewable position without having to touch the display unit 10, thereby putting the front panel 16 in the most easily viewable state. The display unit 10 can stop its operation (movement) in accordance with the authorized user's fourth message, so that the operation of the display unit 10 can be stopped at the most easily viewable position for the authorized user, and the authorized user can put the front panel 16 in the most easily viewable state.

[0088] The display unit 10 automatically rotates in a clockwise or counterclockwise direction in response to a second message (rotation message) that prompts the authorized user to rotate in a clockwise or counterclockwise direction, so that the front panel 16 can be changed to either a vertically long state or a horizontally long state simply by the voice of the authorized user, and the front panel 16 can be automatically changed to either a vertically long state or a horizontally long state in response to the voice of the authorized user.

[0089] The controller (Web application server 37 or physical server) continuously or periodically collects the voice (speech) uttered by the user using microphone 25 while display unit 10 is in operation (voice collection means).The controller (Web application server 37 or physical server) compares the user voice waveform of the user voice (voice data) collected while display unit 10 is in operation with the identified voice waveform of the voice (voice data) of the authorized user stored by voice waveform storage means (voice waveform comparison means).

[0090] If the user's voice waveform compared by the voice waveform comparison means does not match the identified voice waveform, the controller (Web application server 37 or physical server) determines that the user who uttered the voice (voice) is an unauthorized user and stops the operation of the operating display unit 10 (operation stopping means).If the user's voice waveform compared by the voice waveform comparison means matches the identified voice waveform, the controller (Web application server 37 or physical server) determines that the user who uttered the voice (voice) is a legitimate user and continues the operation of the display unit 10 (operation continuing means).

[0091] The display unit 10 continues to operate only if the user who made the sound (voice) is a legitimate user, and stops operation of the display unit 10 if it is determined that the user who made the sound (voice) is an unauthorized user, so that the display unit 10 cannot be continuously used by unauthorized users and can be continuously used only by authorized users, thereby preventing unauthorized use of the display unit 10 and protecting the personal information and privacy of authorized users.

[0092] The controller (Web application server 37 or physical server) continuously or periodically captures a facial image of the user using the digital camera 24 while the display unit 10 is in operation (facial image capturing means). The controller (Web application server 37 or physical server) compares the facial image of the user (facial image data) captured while the display unit 10 is in operation with the specific facial image (specific facial image data) stored by the specific facial image storage means (facial image comparison means).

[0093] If the face image (face image data) of the user compared by the face image comparison means does not match the specific face image (specific face image data), the controller (Web application server 37 or physical server) determines that the user of the face image is an unauthorized user and stops the operation of the operating display unit 10 (operation stopping means).If the face image (face image data) of the user compared by the face image comparison means matches the specific face image (specific face image data), the controller (Web application server 37 or physical server) determines that the user of the face image is a valid user and continues the operation of the display unit 10 (operation continuing means).

[0094] The display unit 10 continues to operate only if the user whose face image has been taken is a legitimate user, and stops operating if it is determined that the user whose face image has been taken is an unauthorized user, so that the display unit 10 cannot be continuously used by unauthorized users and can be continuously used only by authorized users, thereby preventing unauthorized use of the display unit 10 and protecting the personal information and privacy of authorized users.

[0095] After the LED lighting 28 is activated, if the user moves away from the front of the front panel 16 and the motion sensor 26 no longer detects the user (person), the motion sensor 26 sends a non-human detection signal to the controller. The controller (Web application server 37 or physical server) receiving the non-human detection signal from the motion sensor 26 stops (turns off) the activated LED lighting 28 (lighting-off means). Alternatively, after the LED lighting 28 is activated, if the area around the display unit 10 becomes bright, for example, due to natural light, and the light detection sensor 27 detects light around the display unit 10, the light detection sensor 27 sends a light detection signal to the controller. The controller (Web application server 37 or physical server) receiving the light detection signal from the light detection sensor 27 stops (turns off) the activated LED lighting 28 (lighting-off means). Furthermore, when the operation of the operating display unit 10 is stopped by the operation stopping means, the activated LED lighting 28 is stopped (turned off) (lighting-off means).

[0096] FIG. 8 is a diagram showing an example of a menu screen output on the front panel 16 of the display unit 10, and FIG. 9 is a diagram showing an example of a website introduction information screen output on the front panel 16 of the display unit 10. FIG. 10 is a diagram showing an example of an online medical consultation screen output on the front panel 16 of the display unit 10. One example of the use of the display unit 10 is an interaction function in which an authorized user has a two-way conversation with an interlocutor via the display unit 10. This interaction function will be explained using an example in which the interlocutor is a doctor and an online medical consultation is conducted with the doctor. Note that the interlocutor includes any interlocutor with whom the authorized user can have a conversation, and the interaction includes all types of conversations that take place between multiple interlocutors.

[0097] When the display unit 10 starts up, a standby screen (not shown) is output (displayed) on its front panel 16. On the standby screen, a terrestrial digital broadcasting icon, a BS digital broadcasting icon, a CS digital broadcasting icon, a game icon, a display system icon, and an OFF button are output (displayed). When the OFF button is tapped (clicked), a message indicating OFF is pronounced, or the OFF button on the remote control is pressed, the display unit 10 turns off and stops (the same applies to the OFF button below).

[0098] By tapping (clicking) a terrestrial digital broadcasting icon, a BS digital broadcasting icon, or a CS digital broadcasting icon, or by uttering a message indicating the broadcasting icon and selecting the broadcasting icon using the remote control, various broadcasts can be viewed on the display unit 10. By tapping (clicking) a game icon, or by uttering a message indicating the game icon, or by selecting the game icon using the remote control, various games can be played on the display unit 10. A series of operations on the display unit 10 (such as changing the broadcasting channel, adjusting the volume, playing, and recording) can be performed by voice or using a remote control (not shown).

[0099] When an authorized user uses the display unit 10, they tap the display system icon on the standby screen, pronounce a message indicating the display system icon, or select the display system icon using the remote control. When the display system icon is tapped, pronounced (sound collected by the sound collection means), or selected, the menu screen shown in Fig. 8 is output (displayed) on the front panel 16 of the display unit 10. A request icon 8a, a website introduction icon 8b, and an OFF button 8c are output (displayed) on the menu screen of Fig. 8.

[0100] To obtain the interlocutor information of the doctor (interlocutor) desired by the authorized user (multiple interlocutor information that can respond to the request), the authorized user taps the request icon 8a, speaks a message indicating the request, or confirms (selects) the request icon 8a using the remote control. When the request icon 8a is tapped, the request is spoken, or the request icon 8a is confirmed (selected), a request input screen is output (displayed) on the front panel 16 of the display unit 10, although this is not shown. The request input screen outputs (displays) a request input area for entering the request (keywords), a request confirmation button, a clear button, and an OFF button. When the clear button is tapped (clicked), the request (data) entered in the input area is cleared, and the data is entered again (the same applies to the clear button below).

[0101] After inputting the desired request into the request input area, the authorized user taps the request confirmation button, or speaks a message indicating the desired request. The request message (specific request) spoken by the user is collected using (via) the microphone 25 (specific request collection means), and the request data (keywords) is sent to the controller (Web application server 37 or physical server). The desired request is assumed to be "online medical consultation" or "remote diagnosis."

[0102] When the request determination button is tapped or the request data is sent, the controller (Web application server 37 or physical server) uses the various requests from the legitimate user from the past to the present and the information on multiple interlocutors who can respond to those requests as training data, and estimates through learning multiple doctors (at least one interlocutor) who can respond to the specific requests of the legitimate user that have been input or the specific requests of the legitimate user that have been collected by the specific request collection means (interlocutor estimation means).

[0103] The interlocutor estimation means uses a trained model that has been trained to estimate multiple interlocutors corresponding to multiple various requests of a legitimate user. The trained model is generated using a known artificial intelligence algorithm (machine learning algorithm) such as a neural network. The trained model is created by linking multiple various requests of a legitimate user with an adaptability score that indicates the degree of adaptability of the interlocutor to respond to the multiple various requests.

[0104] The adaptability score uses, for example, a ten-level numerical parameter ranging from 0 to 10. For example, if the adaptability of a person is judged to be high based on the person's responses and reactions to requests, a high numerical parameter is set for that person, if the adaptability of a person is judged to be medium based on the person's responses and reactions to requests, a medium numerical parameter is set for that person, and if the adaptability of a person is judged to be low based on the person's responses and reactions to requests, a low numerical parameter is set for that person. The person estimation means selects (estimates) a doctor (person) with an adaptability score of a high numerical parameter for the requests.

[0105] The controller (Web application server 37 or physical server) uses an interlocutor estimation means to estimate multiple doctors (at least one interlocutor) who can respond to the specific requests input by the legitimate user or the specific requests collected by the specific request collection means, and while accessing other servers used by (connected to) the estimated doctors (interlocutors) via the Internet (network), receives the websites (home pages) of those doctors from other servers using the Internet (network), and outputs (displays) introduction information for various multiple websites received from the other servers on the front panel 16 (interlocutor website introduction information output means).

[0130] After entering a specific request in the website request input area, the authorized user taps the website request confirmation button, or speaks a message indicating the specific request. The request message (specific request) spoken by the user is collected using (via) the microphone 25 (specific request collection means), and the request data (keywords) is sent to the controller (Web application server 37 or physical server). The request is assumed to be "bag shopping" or "bag shopping."

[0131] When the request determination button is tapped or the request data is sent, the controller (Web application server 37 or physical server) uses the various requests from the legitimate user from the past to the present and the various website information corresponding to those requests as training data, and estimates through learning the specific requests of the legitimate user that have been input or the specific requests of the legitimate user that have been collected by the specific request collection means (website estimation means).

[0132] The website estimation means uses a trained model that has been trained to estimate multiple websites that correspond to multiple various requests of legitimate users. The trained model is generated using a known artificial intelligence algorithm (machine learning algorithm) such as a neural network. The trained model is created by linking multiple various requests of legitimate users with an adaptability score that indicates the degree of adaptability of a website that corresponds to each of the multiple various requests.

[0133] The adaptability score uses, for example, a numerical parameter on a 10-point scale from 0 to 10. For example, if a website contains many keywords related to the desired items, a high numerical parameter is set for that website, if a website contains a medium amount of keywords related to the desired items, a medium numerical parameter is set for that website, and if a website does not contain many keywords related to the desired items, a low numerical parameter is set for that website. The website estimation means selects (estimates) websites with adaptability scores of high numerical parameters for the desired items.

[0134] The controller (Web application server 37 or physical server) uses a website estimation means to estimate a website (at least one website) that corresponds to the specific requests of the legitimate user that have been input or the specific requests collected by the specific request collection means, and while accessing other servers that manage the estimated websites via the Internet (network), receives these websites (home pages) from other servers using the Internet (network), and outputs (displays) the various websites received from the other servers on the front panel 16 (website information output means).
