Abstract

An information processing device includes a controller that is configured to: acquire driving behavior information as an indication of prudence of a driver in driving a vehicle, acquire a vehicle avatar corresponding to the vehicle, the vehicle avatar having a basic personality set thereto according to information about the vehicle, create a message according to the basic personality of the vehicle avatar based on the driving behavior information, and output the message, that is created, as an utterance of the vehicle avatar.

First claim

What is claimed is:

1. An information processing device comprising a processor configured to:
acquire driving behavior information as an indication of prudence of a driver in driving a vehicle from one or more sensors provided with the vehicle,
acquire a vehicle avatar corresponding to the vehicle, the vehicle avatar having a basic personality set thereto according to information about the vehicle,
store account information of the vehicle avatar for a predetermined social network service (SNS),
acquire a message by the vehicle avatar output from a machine learning model associated with the vehicle avatar by inputting the driving behavior information to the machine learning model, wherein the machine learning model learns the driving behavior information and messages by the vehicle avatar as teacher data and wherein the message output from the machine learning model is not related to the information about the vehicle and the driving behavior information, but reflects the prudence of the driver in driving the vehicle, and
post the message on the predetermined SNS using the account information of the vehicle avatar at a predetermined time once per day or a timing of end of traveling, wherein the message is displayed as text uttered by the vehicle avatar and the displayed text is updated based on the prudence of the driver.

2. The information processing device according to claim 1 , wherein, in a case where the driving behavior information indicates that driving of the driver is prudent, the processor is configured to create a message indicating that the vehicle avatar has a positive feeling.

3. The information processing device according to claim 1 , wherein, in a case where the driving behavior information indicates that driving of the driver lacks prudence, the processor is configured to create a message indicating that the vehicle avatar has a negative feeling.

4. The information processing device according to claim 1 , wherein
the processor is configured to:
acquire information about an environment of surroundings on a road where the vehicle traveled; and
create the message based on the driving behavior information and the information about the environment.

5. The information processing device according to claim 4 , wherein, in a case where the driving behavior information indicates that driving of the driver lacks prudence and the information about the environment indicates that a surrounding environment negatively affects a feeling of the driver, the processor is configured to create a message indicating that the vehicle avatar has a more positive feeling than in a case where the driving behavior information indicates that driving of the driver lacks prudence and the information about the environment indicates that the surrounding environment does not negatively affect the feeling of the driver.

6. The information processing device according to claim 1 , wherein
the processor is configured to:
acquire information about an environment of surroundings on a road where the vehicle traveled;
create a background of a display screen for the message based on the information about the environment; and
output information about the background of the display screen together with the message.

7. The information processing device according to claim 1 , wherein the driving behavior information includes at least one of a number of times of sudden braking, a number of times of sudden steering, a number of times of sudden starting, and a number of times a horn is sounded.

8. A non-transitory computer-readable recording medium recorded with a program for causing a computer to:
acquire driving behavior information as an indication of prudence of a driver in driving a vehicle from one or more sensors provided with the vehicle,
acquire a vehicle avatar corresponding to the vehicle, the vehicle avatar having a basic personality set thereto according to information about the vehicle,
store account information of the vehicle avatar for a predetermined social network service (SNS),
acquire a message by the vehicle avatar output from a machine learning model associated with the vehicle avatar by inputting the driving behavior information to the machine learning model, wherein the machine learning model learns the driving behavior information and messages by the vehicle avatar as teacher data and wherein the message output from the machine learning model is not related to the information about the vehicle and the driving behavior information, but reflects the prudence of the driver in driving the vehicle, and
post the message on the predetermined SNS using the account information of the vehicle avatar at a predetermined time once per day or a timing of end of traveling, wherein the message is displayed as text uttered by the vehicle avatar and the displayed text is updated based on the prudence of the driver.

9. The non-transitory computer-readable recording medium according to claim 8 , wherein, in a case where the driving behavior information indicates that driving of the driver is prudent, the program causes the computer to create a message indicating that the vehicle avatar has a positive feeling.

10. The non-transitory computer-readable recording medium according to claim 8 , wherein, in a case where the driving behavior information indicates that driving of the driver lacks prudence, the program causes the computer to create a message indicating that the vehicle avatar has a negative feeling.

11. The non-transitory computer-readable recording medium according to claim 8 , wherein
the program causes the computer to:
acquire information about an environment of surroundings on a road where the vehicle traveled; and
create the message based on the driving behavior information and the information about the environment.

12. The non-transitory computer-readable recording medium according to claim 11 , wherein, in a case where the driving behavior information indicates that driving of the driver lacks prudence and the information about the environment indicates that a surrounding environment negatively affects a feeling of the driver, the program causes the computer to create a message indicating that the vehicle avatar has a more positive feeling than in a case where the driving behavior information indicates that driving of the driver lacks prudence and the information about the environment indicates that the surrounding environment does not negatively affect the feeling of the driver.

13. The non-transitory computer-readable recording medium according to claim 8 , wherein
the program causes the computer to:
acquire information about an environment of surroundings on a road where the vehicle traveled; create a background of a display screen for the message based on the information about the environment; and
output information about the background of the display screen together with the message.

14. An information processing method executed by a computer comprising:
acquiring, from one or more sensors provided in a vehicle, driving behavior information as an indication of prudence of a driver in driving the vehicle,
acquiring a vehicle avatar corresponding to the vehicle, the vehicle avatar having a basic personality set thereto according to information about the vehicle,
storing account information of the vehicle avatar for a predetermined social network service (SNS),
acquiring a message by the vehicle avatar output from a machine learning model associated with the vehicle avatar by inputting the driving behavior information to the machine learning model, wherein the machine learning model learns the driving behavior information and m
