Hereinafter, embodiments for carrying out the present invention will be described in detail with reference to the drawings.

(First embodiment)
FIG. 1 is a block diagram showing a configuration example of an information presentation device 1 according to the first embodiment. The information presentation 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 presentation 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"). Then, positional relationship estimation section 11 outputs positional relationship information indicating the estimated positional relationship to screen layout determination section 12 . The positional information of the user is acquired using a microphone, an environmental camera, Bluetooth (registered trademark), UWB (Ultra Wide Band), etc., which function in cooperation with the information presentation device 1, and is transmitted to the positional relationship estimation unit 11. .

The screen layout determining unit 12 dynamically determines the screen layout of information to be presented according to the positional relationship estimated by the positional relationship estimating unit 11. The screen layout determination unit 12 then generates display information based on the determined screen layout, and outputs the display information 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 relationships among the three users U1, U2, and U3, determines a screen layout based on the estimated positional relationships, and displays information based on the determined screen layout. is output to the transmissive display D (screen display unit 13). In FIG. 2A, the user U3 is having a conversation with the users U1 and U2 who are side by side with the transmissive display D interposed therebetween. At this time, as seen from the user U3, normal characters are presented on the screen used by the user U3, and reversed characters are presented on the screens used by the users U1 and U2. In FIG. 2B, user U2 and U user U3 who are side by side are having a conversation with user U1 with transmissive display D interposed therebetween. At this time, as seen from the user U2 and the user U3, normal characters are presented on the screens used by the users U2 and U3, and reversed characters are presented on the screen used by the user U1.

　Fig. 3 is a diagram explaining the dynamic change of the screen layout according to the positional relationship during the dialogue. Depending on the characteristics of the conversation, there are two types of positional relationships during conversation: one in which the respondent and the conversation partner face each other across a single transmissive display D and view the screen (hereinafter referred to as mode A); A mode (hereinafter referred to as mode B) in which the other party views the same screen of one transmissive display D from a side-by-side position is also included. According to these positional relationships, in form A shown on the left side of FIG. 3, a screen layout is presented in which normal characters are presented on the screen of the attendant and reversed characters are presented on the screen of the conversation partner. On the other hand, in mode B shown on the right side of FIG. 3, a screen layout for presenting normal characters is presented on the screens of the attendant and the conversation partner. Here, when the positional relationship between the respondent and the conversation partner changes, the screen layout is dynamically changed according to the positional relationship. In mode B, the viewing directions of the respondent and the conversation partner are the same, so it is easy to have a conversation with reference to an object.

For example, it is possible to start a face-to-face correspondence with a foreign tourist in Form A using translation, and from the middle of the conversation, use a nearby guide board in Form B to have a conversation.

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

In step S101, upon receiving the user's position information, the positional relationship estimation unit 11 estimates the positional relationship.

In step S102, the screen layout determining unit 12 determines the screen layout of information to be presented based on the positional relationship estimated by the positional relationship estimating 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 ongoing, the steps from step S101 to step S103 are repeatedly executed, and as shown in FIG. When the mode is changed from the mode A to the mode A, the screen layout for displaying information is changed accordingly. When it is determined that the conversation has ended, the information display ends.

According to the information presentation device 1 according to the present embodiment, it is possible to dynamically change the screen layout according to the positional relationship. Information can be used with the corresponding screen layout.

(Second embodiment)

The positional relationship DB 16 associates and stores the use position of the respondent and the position 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/location estimation unit 15 can estimate the location of the speaker based on the loudness of the voice. Then, the speaker/position estimation unit 15 outputs position information indicating the estimated speech position to the positional relationship estimation unit 11 and updates the speaker position information stored in the positional relationship DB 16 .

The positional relationship estimation unit 11 refers to the positional relationship DB 16 and estimates the positional relationship between the speakers participating in the conversation, triggered by the end of the processing in the speaker/position estimation unit 15 . For example, if there are two speakers A and B, we assume that they are standing on the same side of the display, with speaker A on the right and speaker B on the left. . As another example, assume that speakers A and B are facing different sides of the display. Then, positional relationship estimating section 11 outputs positional relationship information indicating the estimated positional relationship to screen layout determining section 12 .

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

Before the information presentation device 2 executes the information presentation method, as a preparation, it associates the usage position of the respondent with the position of the microphone and stores them in the positional relationship DB 16 .

Here, face authentication refers to an authentication method that identifies an individual based on the positions of feature points such as the eyes, nose, and mouth of the face, as well as the position and size of the face area. On the other hand, face recognition identifies people, but does not identify individuals. That is, if face authentication is performed using the information registered in the face authentication DB 18, it is possible to distinguish between the attendant and the customer.

The face authentication DB 18 pre-registers the face authentication information required to identify the respondent as a specific individual by face authentication.

The speaker/position estimation unit 15 executes face recognition based on the image information acquired by the image acquisition unit 17 to estimate the user's position information. Then, the speaker/position estimation unit 15 outputs the estimated position information of the user to the positional relationship estimation unit 11 . In addition, the speaker/position estimation unit 15 updates the position information of the user stored in the positional relationship DB 16 .

In addition, the speaker/position estimation unit 15 performs face authentication based on the face authentication information registered in the face authentication DB 18 and the image information acquired by the image acquisition unit 17, are estimated separately. The respondent is, for example, a customer service staff, and the other user is, for example, a conversation partner of the respondent.

The positional relationship estimating unit 11 refers to the positional relationship DB 16 to estimate the positional relationship, and outputs the estimated positional relationship to the screen layout determining unit 12 when the processing in the speaker/position estimating unit 15 ends. In the above-described Embodiment 2, since face authentication is not used, as a preparation, the use position of the person receiving the call and the position of the microphone are linked and stored in the positional relationship DB 16. However, in Embodiment 3, face authentication is used. , there is no need to predetermine the position of the attendant.

It should be noted that the information presentation device 3 according to the third embodiment may further include the above-described voice acquisition section 14 in addition to the image acquisition section 17 . The voice acquisition unit 14 outputs voice information indicating the acquired voice to the speaker/position estimation unit 15 .

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

Before the information presentation device 3 executes the information presentation method, as a preparation, the information of the responder necessary for identifying the responder as a specific individual by face authentication is registered in the face authentication DB 18.

In step S301, the image acquisition unit 17 of the information presentation device 3 acquires image information of the speaker's face for performing face authentication and face 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 position information of the speaker 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 determining unit 12 determines the screen layout of information to be presented based on the positional relationship estimated by the positional relationship estimating 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 ongoing, the steps from step S301 to step S305 are repeatedly executed, and as shown in FIG. When the mode is changed from the mode A to the mode A, the screen layout for displaying information is changed accordingly. When it is determined that the conversation has ended, the information display ends.

According to the information presentation device 3 according to this embodiment, it is possible to acquire the user's location information by a simple method. In addition, since it is possible to distinguish between the responder and other users, it is possible to present different information to the responder and other users. Further, when the sound acquisition unit 14 is combined with the image acquisition unit 17, the user's position information can be acquired with higher accuracy.
