A categorical approach to affective gesture recognition

Studies on emotion are currently receiving a lot of attention. The importance of emotion in the development and support of intelligent and social behaviour has been highlighted by studies in psychology and neurology. Hence, the recognition of affective states has also become a critical feature in robot social development, with robots assumed to take on a role as social companion. In this paper, we address the issue of endowing robots with the ability to learn incrementally to recognize the affective state of their human partner by interpreting their gestural cues. We propose a model that can self-organize postural features into affective categories, and use contextual feedback from the partner to drive the learning process.
