Capture User Emotions during Computer- Aided Design

Facial expressions, gestures are artefacts of nonverbal human communication and imply affective states. Recent research on emotion-recognition has shown the potential for human-computer interfaces (HCI) to integrate affect in human machine interaction and mimic human communication models. Each mutually elaborates the other and both can be further elaborated by speech that accompanies the affective status. This paper investigates affecting properties in users performing an engineering design task in Solid EdgeTM. A fuzzy logic model is introduced so as to map psycho-physiological signals to associated affective emotions. By studying the psychophysiological attributes associated to a CAD-based engineering design process it is envisaged that interrelated engineering behaviours can be more deeply understood and consequently, lead to more natural and intuitive CAD user interfaces.
