Emotion prediction device, method, program, and vehicle

An emotion prediction method executed by a computer of an emotion prediction device mounted on a vehicle, the emotion prediction method comprising:

• a first prediction step of predicting an emotion of a user based on a facial expression of the user;
• a second prediction step of predicting an emotion of the user based on a motion of the user;
• a third prediction step of predicting an emotion of the user based on the emotion predicted in the first prediction step and the emotion predicted in the second prediction step;
• and
• an execution restriction step of restricting execution of at least a part of the first prediction step, the second prediction step, and the third prediction step, based on at least a processing load of the computer.

• a second prediction step of predicting an emotion of the user based on a motion of the user;
• a third prediction step of predicting an emotion of the user based on the emotion predicted in the first prediction step and the emotion predicted in the second prediction step;
• and
• an execution restriction step of restricting execution of at least a part of the first prediction step, the second prediction step, and the third prediction step, based on at least a processing load of the computer.
