Below, the form for implementing the present invention is explained in detail with reference to the drawings.

First Embodiment
Fig. 1 is a block diagram showing an example of a 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.

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"). The positional relationship estimation unit 11 then outputs 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), etc. that function in conjunction with the information presentation device 1, and is transmitted to the positional relationship estimation unit 11.

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.

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.

2A and 2B, the information presentation 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 having a conversation 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, and inverted characters are presented on the screen used by users U1 and U2, as seen from user U3. In FIG. 2B, users U2 and U3, who are side by side, are having a conversation with user U1, across the transparent display D. At this time, normal characters are presented on the screen used by users U2 and U3, and inverted characters are presented on the screen used by user U1, as seen from users U2 and U3.

Figure 3 is a diagram for explaining dynamic changes in 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 across one transparent display D 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 these positional relationships, in form A shown on the left of Figure 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 Figure 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 between the respondent and the conversation partner changes during the conversation, 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 referring to objects.

For example, it is possible to start a face-to-face conversation 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.

Figure 4 is a flowchart showing an example of an information presentation method executed by the information presentation device 1.

In step S101, when the user's location information is received, the location relationship estimation unit 11 estimates the location relationship.

In step S102, 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.

In step S103, the screen display unit 13 displays information based on the screen layout determined by the screen layout determination unit 12.

In step S104, if it is determined that the conversation is continuing, steps S101 to S103 are repeatedly executed, and as shown in FIG. 3, if the positional relationship 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. If it is determined that the conversation has ended, the information display is terminated.

According to the information presentation device 1 of this embodiment, it is possible to dynamically change the screen layout depending on 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.

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 given the same reference numbers as those of the first embodiment, and the description thereof will be omitted as appropriate.

The voice acquisition unit 14 is a microphone or the like that acquires the user's speech. The voice acquisition unit 14 outputs voice information indicating the acquired speech to the speaker/position estimation unit 15.

The location relationship DB16 stores the respondent's usage location in association with the location of the voice acquisition unit 14.

The speaker/position estimation unit 15 estimates the position of the speaker (the user who spoke 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. The speaker/position estimation unit 15 then 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.

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. The positional relationship estimation unit 11 then outputs positional relationship information indicating the estimated positional relationship to the screen layout determination unit 12.

Figure 6 is a flowchart showing an example of an information presentation method performed by the information presentation device 2 relating to the second embodiment.

Before the information presentation device 2 executes the information presentation method, as a preliminary step, the user's position and the microphone position are linked and stored in the positional relationship DB 16.

In step S201, the voice acquisition unit 14 of the information presentation device 2 acquires the spoken voice.

In step S202, 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.

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

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.

In step S205, the screen display unit 13 displays information based on the screen layout determined by the screen layout determination unit 12.

In step S206, if it is determined that the conversation is continuing, steps S201 to S205 are repeatedly executed, and as shown in Fig. 3, 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. If it is determined that the conversation has ended, the information display is terminated.

According to the information presentation device 2 of this embodiment, the user's location information can be obtained in a simple manner.

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 the 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 given the same reference numbers as those of the second embodiment, and descriptions thereof will be omitted as appropriate.

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

Here, facial recognition refers to an authentication method that distinguishes individuals based on the positions of facial features such as the eyes, nose, and mouth, and the position and size of the facial area. On the other hand, facial recognition distinguishes that a person is a person, but does not distinguish individuals. In other words, by performing facial recognition using the information registered in the facial recognition DB18, it is possible to distinguish between a customer and a waiter.

The facial recognition DB18 pre-registers the facial recognition information required to identify the person in question as a specific individual through facial recognition.

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. The speaker/position estimation unit 15 then 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.

In addition, 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 is speaking to the person and other users by distinguishing between them. The person who is speaking to the person is, for example, a customer service staff member, and the other users are, for example, the person who is speaking to the person who is speaking to the person.

The positional relationship estimation unit 11, upon the completion of processing by the speaker/position estimation unit 15, 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 embodiment 2, 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 embodiment 3, it is not necessary to determine the position of the person who answers the phone in advance.

The information presentation 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.

Figure 8 is a flowchart showing an example of an information presentation method performed by the information presentation device 3 relating to the third embodiment.

Before the information presentation device 3 executes the information presentation method, as a preliminary preparation, information on the respondent required to identify the respondent as a specific individual through facial recognition is registered in the facial recognition DB 18.

In step S301, the image acquisition unit 17 of the information presentation device 3 acquires image information of the speaker's face to perform facial authentication and facial recognition.

In step S302, the speaker/position estimation unit 15 performs face authentication and face recognition to estimate the speaker and its position, and updates the speaker's position information stored in the positional relationship DB 16.

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

In step S304, 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.

In step S305, the screen display unit 13 displays information based on the screen layout determined by the screen layout determination unit 12.

In step S306, if it is determined that the conversation is continuing, steps S301 to S305 are repeatedly executed, and as shown in FIG. 3, if the positional relationship 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. If it is determined that the conversation has ended, the information display is terminated.

According to the information presentation device 3 of this embodiment, the user's location information can be obtained by a simple method. In addition, since it is possible to distinguish between the person in charge and other users, it is possible to present different information to the person in charge and other users. Furthermore, when the image acquisition unit 17 is combined with the voice acquisition unit 14, the user's location information can be obtained with higher accuracy.
