Emotion expression of an affective state space; a humanoid robot displaying a dynamic emotional state during a soccer game

Following a soccer game is an example where clear emotions are displayed. This example is worked out for a humanoid robot which can express emotions with body language. The emotions expressed by the robot are not just stimuli-response, but are based on an affective state which shows dynamic behavior during the game. This can be live demonstrated with a Nao who follows the game sitting when the match is uneventful. As soon as the game becomes attractive, the Nao stands up, and shows his pleasure or displeasure. By showing these type of emotional expressions the robot can be seen as a sort of partner, which facilitates the cooperation with humans.
