Abstract

A processing result error detection device includes: a behavior recognition unit which recognizes behavior of a user; a processing unit which executes a process dependent on the behavior of the user; an emotion presumption unit which presumes an intensity of emotion of the user based on reaction of the user to a processing result; and a judgment unit which judges that the processing result includes an error when the presumed intensity of emotion of the user is equal to or greater than a predetermined threshold.

First claim

We claim:

1. A processing result error detection device comprising:
a processor configured to implement controllers comprising:
a behavior recognition controller configured to recognize behavior of a user including reaction of the user;
a processing controller configured to execute a process dependent on the behavior of the user;
an emotion presumption controller configured to presume an intensity of first emotion of the user, before the process being executed, based on behavior of the user corresponding to an instruction of the user, and presume an intensity of second emotion of the user by using reaction of the user to a processing result of the process executed by the processing controller; and
a judgment controller configured to adjust a predetermined threshold by using the intensity of the first emotion of the user before the process being executed and judge that the processing result includes an error when the presumed intensity of the second emotion of the user is equal to or greater than the predetermined threshold.

2. The processing result error detection device according to claim 1 , wherein
the emotion presumption controller is configured to presume a type of emotion of the user as well as the intensity of emotion of the user by using the reaction of the user to the processing result, and
in a case where the type of emotion of the user is a negative emotion type, the judgment controller sets the threshold to a smaller value than in a case where the type of emotion of the user is a positive emotion type.

3. The processing result error detection device according to claim 1 , wherein
the judgment controller judges that the processing result includes a first error with erroneous recognition of an instruction of the user when the intensity of emotion of the user is equal to or greater than a predetermined first threshold, and judges the processing result includes a second error without the erroneous recognition of the instruction of the user when the intensity of emotion of the user is less than the first threshold and is equal to or greater than a second threshold, the second threshold being smaller than the first threshold.

4. The processing result error detection device according to claim 1 , wherein
the emotion presumption controller is configured to presume a type of emotion of the user as well as the intensity of emotion of the user by using the reaction of the user in response to the processing result, and
the judgment controller judges that the processing result includes the error when the type of emotion of the user is a specific type and the intensity of emotion of the user is equal to or greater than the threshold.

5. The processing result error detection device according to claim 4 , wherein
the specific type includes a positive type of emotion.

6. A moving entity comprising the processing result error detection device according to claim 1 .

7. The processing result error detection device according to claim 1 , wherein, when the intensity of emotion of the user before the process being executed is equal to or larger than a predetermined value and the emotion is positive type of emotion, the judgment controller adjusts the threshold to be larger value for positive type of emotion and adjusts the threshold to be smaller value for negative type of emotion.

8. The processing result error detection device according to claim 1 , wherein, when the intensity of emotion of the user before the process being executed is equal to or larger than a predetermined value and the emotion is negative type of emotion, the judgment controller adjusts the threshold to be larger value for negative type of emotion and adjusts the threshold to be smaller value for positive type of emotion.

9. The processing result error detection device according to claim 1 , wherein the processing result error detection device is equipped to a vehicle, the user is a passenger of the vehicle, and the processing controller outputs the processing result by using a display or a speaker to the passenger.

10. A non-transitory computer readable medium storing a processing result error detection program which causes a computer to execute processing comprising steps of:
recognizing behavior of a user including reaction of the user;
presuming an intensity of first emotion of the user, before the process being executed, based on behavior of the user corresponding to an instruction of the user;
adjusting a predetermined threshold by using the intensity of the first emotion of the user before the process being executed;
executing a process dependent on the behavior of the user;
presuming an intensity of second emotion of the user by using the reaction of the user to a processing result of the process executed; and
judging that the processing result includes an error when the presumed intensity of the second emotion of the user is equal to or greater than the predetermined threshold.

11. A processing result error detection method which is executed by a computer, the method comprising steps of:
recognizing behavior of a user including reaction of the user;
presuming an intensity of first emotion of the user, before the process being executed, based on behavior of the user corresponding to an instruction of the user;
adjusting a predetermined threshold by using the intensity of the first emotion of the user before the process being executed;
executing a process dependent on the behavior of the user;
presuming an intensity of second emotion of the user by using the reaction of the user to a processing result of the process executed; and
judging that the processing result includes an error when the presumed intensity of the second emotion of the user is equal to or greater than the predetermined threshold.
