The emotion estimation unit 76 analyzes the facial expression and the contents of the voice information from the image information, and the user 26 does not have a disgust or a feeling of unskilledness toward the destination 91 that has arrived, or other than that. The emotion (impression) at the time of arrival of the destination 91 is estimated.

[motion]
Next, the operation of the recommendation providing system 12 basically configured as described above will be described with reference to the sequence diagram of FIG. 4 centering on the server 10.

In step S1, when the vehicle 14 starts navigation (traveling based on destination setting, recommended route setting, and route guidance along the recommended route 80), in step S11, the navigation information acquisition unit 66 of the server 10 is contacted. The navigation information (the set destination 91, the set recommended route 80, and the traveling state based on the route guidance along the recommended route) transmitted from the vehicle 14 is acquired.

Until the vehicle 14 ends the navigation in step S2 (step S2: YES), in the server 10, the arrival determination unit 68 arrives at the destination from the acquired (received) navigation information in step S12. (Step S12: YES) or not (step S12: NO) is determined.

When the navigation of the vehicle 14 is completed in step S2 (step S2: YES), that is, when the current position of the vehicle 14 is near the destination 91, the arrival determination unit 68 of the server 10 aims at the vehicle 14. It is determined that the vehicle has arrived at the ground (step S12: YES).

The server 10 starts when it is determined in step S13 that the vehicle 14 has arrived at the destination 91, or before a predetermined distance (predetermined time), for example, several hundred meters (several tens of seconds) before the arrival. The image / audio information acquisition unit 74 of 10 requests the navigation device 16 to transmit the image information acquired by the vehicle-mounted camera 43 and the audio information acquired by the microphone 44 in real time.

Based on this request, in step S3, the image / voice information acquisition unit 46 of the vehicle 14 receives the request (immediately before arriving at the destination 91) and several tens of seconds after the navigation of the vehicle 14 is completed (when the navigation of the vehicle 14 is completed). Until immediately after arrival at the destination 91), the image information captured and recorded by the in-vehicle camera 43 of the occupant including the user 26 by the in-vehicle camera 43 and the voice information of the occupant including the user 26 recorded by the microphone 44 are transmitted. .. It should be noted that the staying time may be recorded for several tens of seconds when departing from the destination 91 which is equal to or less than the lower limit of the average staying time. In step S14, the image / audio information acquisition unit 74 of the server 10 temporarily stores the transmitted image information and audio information in the storage unit 62.

In step S15, the staying time determination unit 70 determines whether or not the vehicle 14 arrives at the destination 91 and the staying time at the arriving destination 91 is equal to or less than the lower limit of the average staying time at the destination 91. Is determined.

If the staying time exceeds the lower limit of the average staying time (step S15: NO), it is determined that the user 26 of the vehicle 14 has achieved what he / she was aiming to achieve at the destination 91. And end the process.

If the staying time is less than or equal to the lower limit of the average staying time (step S15: YES), in step S16, the recommendation making unit 72 cannot accomplish what it was aiming to accomplish at the destination 91. As a result, information on a recommendation (revisit recommendation) for revisiting the destination 91 is created and stored in the storage unit 62.

The revisit recommendation information stored in the storage unit 62 is based on the premise that the revisit recommendation in step S19, which will be described later, is maintained. For example, the server 10 navigates the vehicle 14 in the next step S11. When the acquisition of new navigation information was started from the device 16, the recommendation creation section of the navigation device 16 of the vehicle 14 revisited the recommendation information ("It seems that the predetermined thing was not achieved at the destination last time. Information indicating "Why don't you set the unvisited destination (restaurant 91A or Ferris wheel 91B) as the destination that could not be achieved?") Is transmitted, and the display unit 32 is transmitted through the recommendation processing unit 28 of the navigation device 16. Display above. Alternatively, for example, the revisit recommendation information may be referred to from the setting history of the destination displayed on the display unit 32.

In step S17, the emotion estimation unit 76 of the server 10 estimates the presence or absence of disgust of the user 26 based on the facial expression of the user 26 from the image information / voice information stored in the storage unit 62. For example, if you detect a facial expression that wrinkles your nose, raises your upper lip, or combines the characteristics of both, or if you detect a voice such as "I don't feel good", you have a disgust (step). S17: Disgust) is determined.

In this case, it is considered that the user 26 does not intend to return to the destination 91 where he / she has arrived, and in step S18, the revisit recommendation stored in the storage unit 62 is deleted, and the process ends. The destination 91, which is the target of disgust, may be stored in association with the user 26 and used as data to be referred to when recommending POI information.

Further, the emotion estimation unit 76 estimates the presence or absence of unskilled feeling of the user 26 based on the facial expression of the user 26 from the image information / voice information. For example, when the eyebrows are pulled up, the eyelids are pulled up and down, the eyes are wide open, the chin is lowered and the lips and teeth are separated, or when a voice such as "sold out" or "closed" is detected. If this is the case, it is determined that there is an unskilled feeling, or if the disgust / unskilled feeling is unknown, it is determined that there is an unskilled feeling or not.

In this case, the revisit recommendation is maintained and the process ends in step S19.

In addition, when it is determined that there is a feeling of unskilledness and when it is determined that there is a feeling of unskilledness or it is unknown, the method of revisiting recommendation may be adjusted. For example, if it is determined that there is a feeling of unskilledness, a revisit recommendation may be made by voice from the speaker 36, and if it is determined that there is a feeling of unskilledness or not, it may be displayed only in characters on the display unit 32. ..

If the person arrives at the destination 91 but the staying time is equal to or less than the lower limit of the average staying time, it is predicted that the purpose has not been achieved for some reason. Therefore, the POI information, which is an alternative destination that can achieve the same purpose, may be recommended.
