Abstract:

The paper addresses methodological issues in the analysis of gaze behaviour and introduces a novel computer-based procedure for experimental gaze control in ongoing dyadic interactions. An avatar platform is used to transmit and display nonverbal behaviour (head and body movement, gestures) as captured by motion capture devices and data gloves in real time while a computer algorithm is substituting the real gaze behaviour of one of the interlocutors by simulated gaze sequences. Duration of directed gaze (looking into the face of the vis-a-vis) was varied as an independent variable, lasting 2 seconds in one condition and four seconds in the other. Person perception as measured by means of an adjective list and social presence as measured by means of a short questionnaire served as dependent variables. The results underline the validity of the computer animation approach. Consistent with the literature the longer gaze duration was found to cause significantly better evaluations of the interaction partner.
