Multi-Modal Emotion Expression for Affective Human-Robot Interaction

Boekbijdrage - Boekhoofdstuk Conferentiebijdrage

Probo is a social robot intended to comfort and emotionally interact with hospitalized children. Therefore it requires the ability to express emotions. In order to do so, an emotional interface
is developed to fully configure the display of emotions. The emotions, represented as a vector in an emotion space, are mapped to the degrees of freedom used in our robot. An affective gibberish speech is used as a means for auditory emotion expression. Gibberish speech consists of vocalizations of
meaningless strings of speech sounds. The advantage of gibberish in affective computing lies with the fact that no understandable text has to be pronounced and that only affect is conveyed. In this paper, Probo's ability to express multi-modal emotion is described and the recognition of the underlying emotions based on the robot's facial expressions and gibberish affective speech were tested in user studies with children.
