[0012] Hereinafter, an embodiment of the present invention will be described in detail with reference to the drawings.

[0013] (First embodiment) Fig. 1 is a block diagram showing an example of the configuration of an information display device 1 according to a first embodiment. The information display device 1 shown in Fig. 1 includes a positional relationship estimation unit 11, a screen layout determination unit 12, and a screen display unit 13. Note that the screen display unit 13 may be provided outside the information display device 1.

[0014] The positional relationship estimation unit 11 receives and acquires the user's positional information, and estimates the user's positional relationship with respect to the screen display unit 13 (hereinafter simply referred to as "positional relationship"). Then, the positional relationship estimation unit 11 outputs the positional relationship information indicating the estimated positional relationship to the screen layout determination unit 12. The user's positional information is acquired using a microphone, an environmental camera, Bluetooth (registered trademark), UWB (Ultra Wide Band), or the like that functions in cooperation with the information presentation device 1, and is transmitted to the positional relationship estimation unit 11.

[0015] The screen layout determination unit 12 dynamically determines the screen layout of the information to be presented in accordance with the positional relationship estimated by the positional relationship estimation unit 11. Then, the screen layout determination unit 12 generates display information based on the determined screen layout and outputs it to the screen display unit 13.

[0016] The screen display unit 13 is a display that displays the display information input from the screen layout determination unit 12. The screen display unit 13 is, for example, a liquid crystal display or an organic EL (Electro-Luminescence) display. The display may be a transmissive display.

[0017] In FIG. 2A and FIG. 2B, the information display device 1 estimates the positional relationship of three users U1, U2, and U3, determines a screen layout based on the estimated positional relationship, and outputs information based on the determined screen layout to the transparent display D (screen display unit 13). In FIG. 2A, user U3 is talking with users U1 and U2 who are side by side across the transparent display D. At this time, normal characters are presented on the screen used by user U3 from the user U3's perspective, and inverted characters are presented on the screen used by users U1 and U2. In FIG. 2B, users U2 and U3 who are side by side are talking with user U1 across the transparent display D. At this time, normal characters are presented on the screen used by users U2 and U3 from the user U2 and U3's perspective, and inverted characters are presented on the screen used by user U1.

[0018] FIG. 3 is a diagram for explaining dynamic change of the screen layout according to the positional relationship during conversation. The positional relationship during conversation includes a form in which the respondent and the conversation partner face each other with one transparent display D between them and view the screen (hereinafter referred to as form A) and a form in which the respondent and the conversation partner view the same screen of one transparent display D side by side (hereinafter referred to as form B) according to the characteristics of the conversation. According to these positional relationships, in form A shown on the left of FIG. 3, a screen layout is presented in which normal characters are presented on the screen of the respondent and inverted characters are presented on the screen of the conversation partner. On the other hand, in form B shown on the right of FIG. 3, a screen layout is presented in which normal characters are presented on the screens of the respondent and the conversation partner. Here, when the positional relationship during the conversation between the respondent and the conversation partner changes, the screen layout is dynamically changed according to the positional relationship. In form B, the viewing direction of the respondent and the conversation partner is the same, making it easy to have a conversation by referring to objects.

[0019] For example, it is possible to start face-to-face interaction with a foreign tourist using mode A, using translation, and then, midway through the conversation, continue the conversation using mode B, using nearby information boards.

[0020] FIG. 4 is a flowchart showing an example of an information display method executed by the information display device 1.

[0021] In step S101, upon receiving user position information, the positional relationship estimation unit 11 estimates the positional relationship.

[0022] In step S102, screen layout determination section 12 determines the screen layout of information to be presented based on the positional relationship estimated by positional relationship estimation section 11.

[0023] In step S 103 , the screen display unit 13 displays information based on the screen layout determined by the screen layout determination unit 12 .

[0024] In step S104, if it is determined that the conversation is continuing, steps S101 to S103 are repeatedly executed, and if the positional relationship during this time changes from form A to form B, or from form B to form A, the screen layout for displaying information is changed accordingly, as shown in Fig. 3. If it is determined that the conversation has ended, the information display is terminated.

[0025] According to the information presentation device 1 of this embodiment, it is possible to dynamically change the screen layout according to the positional relationship, and information can be used in a screen layout that corresponds to the characteristics of the conversation, such as the number of participants and the direction in which the information is viewed, without complicated operations.

[0026] Second Embodiment Next, an example of acquiring user position information using voice will be described as a second embodiment. FIG. 5 is a block diagram showing a configuration example of an information display device 2 according to the second embodiment. The information display device 2 shown in FIG. 5 includes a positional relationship estimation unit 11, a screen layout determination unit 12, a screen display unit 13, a voice acquisition unit 14, a speaker / position estimation unit 15, and a positional relationship DB 16. The information display device 2 is different from the information display device 1 according to the first embodiment in that it further includes the voice acquisition unit 14, the speaker / position estimation unit 15, and the positional relationship DB 16. The same configurations as those of the first embodiment are denoted by the same reference numbers as those of the first embodiment, and descriptions thereof will be omitted as appropriate.

[0027] The voice acquiring unit 14 is a microphone that acquires the user's voice, etc. The voice acquiring unit 14 outputs voice information indicating the acquired voice to the speaker / position estimating unit 15.

[0028] The positional relationship DB 16 stores the user's location and the location of the voice capture unit 14 in association with each other.

[0029] The speaker / position estimation unit 15 estimates the position of a speaker (a user who has spoken at a certain point in time) based on the voice acquired by the voice acquisition unit 14. For example, if the voice acquisition unit 14 is a directional microphone or a microphone array, the speaker / position estimation unit 15 can estimate the position of the speaker based on the volume of the voice. Then, the speaker / position estimation unit 15 outputs position information indicating the estimated speaking position to the positional relationship estimation unit 11, and updates the speaker position information stored in the positional relationship DB 16.

[0030] When the speaker / position estimation unit 15 finishes processing, the positional relationship estimation unit 11 refers to the positional relationship DB 16 and estimates the positional relationship between speakers participating in the conversation. For example, if there are two speakers, A and B, it is estimated that speakers A and B are standing on the same side of the display, with speaker A on the right and speaker B on the left. As another example, it is estimated that speakers A and B are standing on different sides of the display and facing each other. Then, the positional relationship estimation unit 11 outputs positional relationship information indicating the estimated positional relationship to the screen layout determination unit 12.

[0031] FIG. 6 is a flowchart showing an example of an information display method executed by the information display device 2 according to the second embodiment.

[0032] Before the information display device 2 executes the information display method, the user's position and the microphone position are associated with each other and stored in the positional relationship DB 16 as advance preparation.

[0033] In step S201, the voice acquisition unit 14 of the information display device 2 acquires a spoken voice.

[0034] In step S 202 , the speaker / position estimation unit 15 estimates the speaker and its position based on the acquired voice data, and updates the speaker and its position information stored in the positional relationship DB 16 .

[0035] In step S203, the positional relationship estimation unit 11 estimates the positional relationship of speakers participating in the conversation based on the information stored in the positional relationship DB 16.

[0036] In step S204, the screen layout determination unit 12 determines the screen layout of the information to be presented based on the positional relationship estimated by the positional relationship estimation unit 11.

[0037] In step S 205 , the screen display unit 13 displays information based on the screen layout determined by the screen layout determination unit 12 .

[0038] In step S206, if it is determined that the conversation is continuing, steps S201 to S205 are repeatedly executed, and if the positional relationship of the speaker changes during this time from form A to form B, or from form B to form A, the screen layout for displaying information is changed accordingly, as shown in Fig. 3. If it is determined that the conversation has ended, the information display is terminated.

[0039] According to the information display device 2 according to this embodiment, it is possible to obtain the user's position information by a simple method.

[0040] (Third embodiment) Next, an example of acquiring user position information using an image will be described as a third embodiment. FIG. 7 is a block diagram showing a configuration example of an information display device 3 according to a third embodiment. The information display device 3 shown in FIG. 7 includes a positional relationship estimation unit 11, a screen layout determination unit 12, a screen display unit 13, a speaker / position estimation unit 15, a positional relationship DB 16, an image acquisition unit 17, and a face authentication DB 18. The information display device 3 is different from the information display device 2 according to the second embodiment in that it includes an image acquisition unit 17 instead of the voice acquisition unit 14, and further includes a face authentication DB 18. The same configurations as those of the second embodiment are denoted by the same reference numbers as those of the second embodiment, and the description thereof will be omitted as appropriate.

[0041] The image acquisition unit 17 is a camera or the like that acquires image information of a user. The image acquisition unit 17 outputs the acquired image information showing the face of the speaker to be used for face recognition and face authentication to the speaker / position estimation unit 15.

[0042] Here, face authentication refers to an authentication method that identifies an individual based on the positions of characteristic points such as the eyes, nose, and mouth on the face, and the position and size of the face area. On the other hand, face recognition identifies that the person is a person, but does not identify the individual. In other words, face authentication based on the information registered in the face authentication DB 18 makes it possible to distinguish between a customer and a waiter.

[0043] The face recognition DB 18 registers in advance face recognition information required for identifying the person who answers the phone as a specific individual through face recognition.

[0044] The speaker / position estimation unit 15 performs face recognition based on the image information acquired by the image acquisition unit 17, and estimates the user's position information. Then, the speaker / position estimation unit 15 outputs the estimated user's position information to the positional relationship estimation unit 11. The speaker / position estimation unit 15 also updates the user's position information stored in the positional relationship DB 16.

[0045] Furthermore, the speaker / position estimation unit 15 performs face recognition based on the face recognition information registered in the face recognition DB 18 and the image information acquired by the image acquisition unit 17, and estimates the positions of the person who serves the person and other users by distinguishing between them. The person who serves the person is, for example, a customer service staff member, and the other users are, for example, people with whom the person serves the person.

[0046] The positional relationship estimation unit 11, when the processing by the speaker / position estimation unit 15 ends, estimates the positional relationship by referring to the positional relationship DB 16, and outputs the estimated positional relationship to the screen layout determination unit 12. In the above-mentioned second embodiment, since face recognition is not used, the use position of the person who answers the phone and the position of the microphone are linked and stored in the positional relationship DB 16 as advance preparation, but since face recognition is used in the third embodiment, it is not necessary to determine the position of the person who answers the phone in advance.

[0047] The information display device 3 according to the third embodiment may further include the above-mentioned voice acquisition unit 14 in addition to the image acquisition unit 17. The voice acquisition unit 14 outputs voice information indicating the acquired voice to the speaker / position estimation unit 15. This enables the speaker / position estimation unit 15 to estimate the speaking position based on the voice acquired by the voice acquisition unit 14.

[0048] FIG. 8 is a flowchart showing an example of an information display method executed by the information display device 3 according to the third embodiment.

[0049] Before the information display device 3 executes the information display method, information on the person in charge of identifying the person in charge as a specific individual by face recognition is registered in the face recognition DB 18 as a preliminary preparation.

[0050] In step S301, the image acquisition unit 17 of the information display device 3 acquires image information of the face of a speaker for executing face authentication and face recognition.

[0051] In step S302, the speaker / position estimation unit 15 executes face authentication and face recognition to estimate the speaker and its position, and updates the speaker position information stored in the positional relationship DB 16.

[0052] In step S303, the positional relationship estimation unit 11 estimates the positional relationship of speakers participating in the conversation based on the information stored in the positional relationship DB 16.

[0053] In step S304, screen layout determination section 12 determines the screen layout of information to be presented based on the positional relationship estimated by positional relationship estimation section 11.

[0054] In step S 305 , the screen display unit 13 displays information based on the screen layout determined by the screen layout determination unit 12 .

[0055] In step S306, if it is determined that the conversation is continuing, steps S301 to S305 are repeatedly executed, and if the positional relationship during this time changes from form A to form B, or from form B to form A, the screen layout for displaying information is changed accordingly, as shown in Fig. 3. If it is determined that the conversation has ended, the information display is terminated.

[0056] According to the information display device 3 of this embodiment, the user's location information can be acquired by a simple method. In addition, since the respondent and other users can be distinguished, it is possible to present different information to the respondent and other users. In addition, when the image acquisition unit 17 is combined with the voice acquisition unit 14, the user's location information can be acquired with higher accuracy.

[0057] (Fourth embodiment) 9A and 9B are block diagrams showing a configuration example of an information display device 4 according to a fourth embodiment. The information display device 4 according to the fourth embodiment is an information display device having a screen display unit that is not only flat but also has a display that can be viewed from any position in 360 degrees. For this reason, the reference numeral 13' is used for the screen display unit of the information display device 4 instead of 13. FIG. 9A is different from FIG. 5, which is a block diagram of the information display device 2 according to the second embodiment, in that it has a screen display unit 13'. FIG. 9B is different from FIG. 7, which is a block diagram of the information display device 3 according to the third embodiment, in that it has a screen display unit 13'.

[0058] As shown in Fig. 10A, when using a display D that can be viewed from any position in 360 degrees, information is output in normal characters when users U1, U2, and U3 look at the screen from their respective positions. Fig. 10B is a bird's-eye view of Fig. 10A from above.

[0059] According to the information display device 4 of this embodiment, the degree of freedom in the viewing direction can be increased, and for example, it becomes possible to display an aerial image.

[0060] Fifth embodiment FIG. 11 is a block diagram showing a configuration example of an information display device 5 according to a fifth embodiment. The information display device 5 shown in FIG. 11 includes a positional relationship estimation unit 11, a screen layout determination unit 12, a screen display unit 13a, a voice acquisition unit 14, a speaker / position estimation unit 15, a positional relationship DB 16, a screen output distribution unit 19, and a screen position DB 20. The information display device 5 is different from the information display device 2 according to the second embodiment in that the information display device 5 further includes the screen output distribution unit 19 and the screen position DB 20. The same components as those in the second embodiment are denoted by the same reference numerals as those in the second embodiment, and the description thereof will be omitted as appropriate. The information display device 5 is connected to one or more screen display units 13b to 13n.

[0061] The screen position DB 20 stores position information of each of the multiple screen display units 13a to 13n.

[0062] The screen layout determination unit 12 determines the screen layout of each of the screen display units 13a to 13n based on the positional relationship estimated by the positional relationship estimation unit 11 and the positional information stored in the screen position DB 20. Then, the screen layout determination unit 12 outputs to the screen output allocation unit 19 display information based on the screen layout of each of the screen display units 13a to 13n.

[0063] 12, when users U1, U2, and U3 are participating in a conversation, the screen layout determination unit 12 generates display information to be presented to user U1 on the transparent display D1, and generates display information to be presented to users U2 and U3 on the transparent display D2, based on the positional relationship between users U1, U2, and U3 and the positions of transparent displays D1 and D2. In the example shown in Fig. 12, as seen from user U2, normal characters are presented on the screen used by user U2, and inverted characters are presented on the screen used by users U1 and U3.

[0064] The screen output distribution unit 19 distributes and transfers the display information input from the screen layout determination unit 12 to the multiple screen display units 13a to 13n.

[0065] The information display device 5 according to the fifth embodiment may present information in cooperation with a plurality of devices. That is, the information display device 5 may present information on a display of a device owned by a conversation partner and provided outside the information display device 5 in cooperation with the device. In this case, the screen display units 13b to 13n in FIG. 11 refer to displays in a plurality of devices. The devices include mobile information terminals such as smartphones and tablets. In this case, the screen output distribution unit 19 transfers display information to the device by short-distance wireless communication such as Bluetooth and UWB.

[0066] The information presentation device 5 according to the fifth embodiment may further include the above-mentioned image acquisition unit 17 and face authentication DB 18 in addition to the voice acquisition unit 14. The image acquisition unit 17 outputs the acquired image information indicating the face of the speaker used for face recognition and face authentication to the speaker / position estimation unit 15. This enables the speaker / position estimation unit 15 to execute face authentication and face recognition based on the image acquired by the image acquisition unit 17, and estimate the position information of the user.

[0067] FIG. 13 is a flowchart showing an example of an information display method executed by the information display device 5 according to the fifth embodiment.

[0068] Before starting the execution of the information presentation method, the positions of each screen are stored in the screen position DB 20 as a preliminary preparation.

[0069] In step S401, the voice acquisition unit 14 of the information display device 5 acquires a spoken voice.

[0070] In step S 402 , the speaker / position estimation unit 15 estimates the speaker and his / her position, and updates the speaker and his / her position information stored in the positional relationship DB 16 .

[0071] In step S403, the positional relationship estimation unit 11 estimates the positional relationship of speakers participating in the conversation based on the information stored in the positional relationship DB 16.

[0072] In step S 404 , screen layout determination section 12 determines the screen layout of the information to be presented based on the positional relationship estimated by positional relationship estimation section 11 and the positional information of each screen stored in screen position DB 20 .

[0073] In step S405, the screen output distribution unit 19 requests each of the screen display units 13a to 13n to determine the display contents and display output based on the screen layout passed from the screen layout determination unit 12.

[0074] In step S406, the screen display units 13a to 13n output information based on the determined screen layout to the screen.

[0075] In step S407, if it is determined that the conversation is continuing, steps S401 to S406 are repeatedly executed, and if the position of the speaker changes during this time from form A to form B, or from form B to form A, the screen layout for displaying information is changed accordingly, as shown in Fig. 3. If it is determined that the conversation has ended, the information display is terminated.

[0076] The positional relationship estimation unit 11, the screen layout determination unit 12, the speaker / position estimation unit 15, and the screen output allocation unit 19 in the above-mentioned information presentation devices 1, 2, 3, 4, and 5 constitute a part of a control and arithmetic circuit (controller).
