[Brief explanation of the drawing]

[0007] [Figure 1] This is a block diagram showing the configuration of the information processing device according to the embodiment. [Figure 2] This is a flowchart showing the flow of the search operation by the information processing device according to the embodiment. [Figure 3] This flowchart shows the flow of the conformance message output operation by the information processing device according to the embodiment. [Modes for carrying out the invention]

[0008] The following describes an embodiment of the information processing device with reference to the drawings. In the following description, the information processing device is assumed to be configured as a device mounted on a vehicle.

[0009] (Device configuration) First, the configuration of the information processing apparatus according to the embodiment will be described with reference to Figure 1. Figure 1 is a block diagram showing the configuration of the information processing apparatus according to the embodiment.

[0010] In Figure 1, the information processing device 10 according to the embodiment is configured as a device capable of outputting messages to a user (i.e., a vehicle occupant) in multiple styles. The information processing device 10 may be configured to include an arithmetic unit (e.g., a processor), a storage device (e.g., RAM (Random Access Memory), ROM (Read Only Memory), a hard disk drive, etc.), a communication device (e.g., a wired communication device or a wireless communication device), an input device (e.g., a keyboard, mouse, touch panel, etc.), and an output device (e.g., a display, speaker, etc.).

[0011] The information processing device 10 includes, as components for realizing its functions, a tolerance storage unit 110, a search message generation unit 120, a search message output unit 130, a tolerance determination unit 140, a conformance message generation unit 150, and a conformance message output unit 160. Note that each of the search message generation unit 120, the search message output unit 130, the tolerance determination unit 140, the conformance message generation unit 150, and the conformance message output unit 160 may be processing blocks implemented by an arithmetic unit. Furthermore, the tolerance storage unit 110 may be a database implemented by a storage device.

[0012] The tolerance storage unit 110 is configured to store the user's tolerance level for each of a plurality of styles pre-set as message output modes. Specific examples of tolerance levels include "proposal tolerance" for suggestive responses, "empathy tolerance" for empathetic responses, "length tolerance" for long messages, "slowness tolerance" for slow messages, "casual tolerance" for casual messages, and "subjectivity tolerance" for subjective responses. Multiple tolerance levels like those described above are stored for each user. The tolerance levels may be stored, for example, as a score corresponding to each of the multiple tolerance levels (i.e., a numerical value that increases as the tolerance level increases).

[0013] The exploration message generation unit 120 is configured to generate exploration messages for determining the user's tolerance level. Based on the information regarding the user's tolerance level stored in the tolerance level storage unit 110 (hereinafter referred to as "tolerance information" as appropriate), the exploration message generation unit 120 generates exploration messages in a style where tolerance information is insufficient. For example, the exploration message generation unit 120 may generate exploration messages in a style where the tolerance information, described later, has been updated infrequently. The exploration message generation unit 120 may generate exploration messages in multiple styles. For example, the exploration message generation unit 120 may generate long, slow, empathetic messages. The exploration message generation unit 120 generates exploration messages using a text generation model that has been trained to generate text in multiple styles.

[0014] The search message output unit 130 is configured to output the search message generated by the search message generation unit 120 to the user. The search message output unit 130 may output the search message using, for example, a display or a speaker.

[0015] The tolerance determination unit 140 is configured to determine the user's tolerance level in response to the user's response to the search message output from the search message output unit 130, and to update the tolerance information stored in the tolerance storage unit 110. Specifically, the tolerance determination unit 140 increases the tolerance level corresponding to the style of the search message when the user's response to the search message is positive (for example, when a reply is given or when the user takes an action in accordance with the message). On the other hand, the tolerance determination unit 140 decreases or maintains the tolerance level corresponding to the style of the search message when the user's response to the search message is negative (for example, when there is no reply or when the user does not take an action in accordance with the message). The tolerance determination unit 140 may update the tolerance information by, for example, increasing or decreasing the score corresponding to each tolerance level.

[0016] The appropriate message generation unit 150 is configured to generate appropriate messages when outputting situation-appropriate messages to the user (for example, when the user makes a question or inputs an action). The appropriate message generation unit 150 generates appropriate messages based on the user's tolerance information stored in the tolerance storage unit 110. For example, the appropriate message generation unit 150 may generate appropriate messages in the style with the highest tolerance. Alternatively, the appropriate message generation unit 150 may generate appropriate messages in a style selected from among multiple styles whose tolerance exceeds a predetermined threshold. In this case, the appropriate message generation unit 150 may generate appropriate messages in multiple styles. The appropriate message generation unit 150 generates appropriate messages using a text generation model that has been trained to generate text in multiple styles. This text generation model may be the same as the model used by the search message generation unit 120.

[0017] The matching message output unit 160 is configured to output matching messages generated by the matching message generation unit 150 to the user. The matching message output unit 160 may output search messages using, for example, a display or a speaker.

[0018] (Searching action) Next, with reference to Figure 2, the flow of the search operation by the information processing device 10 according to the embodiment (i.e., the operation when outputting a search message and determining the user's tolerance level) will be explained. Figure 2 is a flowchart showing the flow of the search operation by the information processing device according to the embodiment.

[0019] As shown in FIG. 2, when the search operation by the information processing apparatus 10 according to the embodiment is started, first, the search message generation unit 120 acquires the user's tolerance information from the tolerance storage unit 110 (step S101). Then, the search message generation unit 120 generates a search message in a style with insufficient tolerance information (step S102). Thereafter, the search message output unit 130 outputs the search message generated by the search message generation unit 120 (step S103).

[0020] Subsequently, the tolerance determination unit 140 acquires the user's reaction to the search message (step S104). Then, the sharing degree determination unit 140 updates the user's tolerance information stored in the tolerance storage unit 110 based on the user's reaction (step S105).

[0021] Note that the above-described search operation may be repeatedly executed. By repeatedly executing the search operation, the tolerance information stored in the tolerance storage unit 110 changes to better reflect the user's preferences.

[0022] (Compatible Message Output Operation) Next, referring to FIG. 3, the flow of the compatible message output operation (that is, the operation when outputting a message in a style suitable for the user) by the information processing apparatus 10 according to the embodiment will be described. FIG. 3 is a flowchart showing the flow of the compatible message output operation by the information processing apparatus according to the embodiment.

[0023] As shown in FIG. 3, when the compatible message output operation by the information processing apparatus 10 according to the embodiment is started, first, the compatible message generation unit 150 acquires the user's tolerance information from the tolerance storage unit 110 (step S201). That is, the compatible message generation unit 150 acquires the sharing degree information updated by the above-described search operation.

[0024] Next, the conformance message generation unit 150 generates a conformance message in a style that is highly acceptable to the user (step S202). Then, the conformance message output unit 160 outputs the conformance message generated by the conformance message generation unit 150 (step S203).

[0025] Furthermore, after outputting the conformance message, the processes in steps S104 and S105 of Figure 2 may be executed. Specifically, the user's response to the conformance message may be obtained, and the stored information in the tolerance storage unit 110 may be updated according to the user's response. In other words, the conformance message may have the same function as the search message output during the search operation.

[0026] (Technical effects) Next, the technical effects obtained by the information processing device 10 according to this embodiment will be described.

[0027] As explained in Figures 1 to 3, in the information processing device 10 according to this embodiment, the user's tolerance for the message style is determined in advance by outputting a search message. Then, when outputting a message afterward, the message is output in a style that matches the user's tolerance. In this way, even when outputting messages with the same meaning, the message can be conveyed to the user in a more appropriate manner.

[0028] This disclosure is not limited to the embodiments described above and can be modified as appropriate without contradicting the gist or idea of ​​the invention as can be inferred from the claims and the specification as a whole. Information processing devices with such modifications are also included within the technical scope of the present invention. [Explanation of Symbols]
