Relations between facial display, eye gaze and head tilt: Dominance perception variations of virtual agents

摘要

In this paper, we focus on facial displays, eye gaze and head tilts to express social dominance. In particular, we are interested in the interaction of different non-verbal cues. We present a study which systematically varies eye gaze and head tilts for five basic emotions and a neutral state using our own graphics and animation engine. The resulting images are then presented to a large number of subjects via a Web-based interface who are asked to attribute dominance values to the character shown in the images. First, we analyze how dominance ratings are influenced by the conveyed emotional facial expression. Further, we investigate how gaze direction and head pose influence dominance perception depending on the displayed emotional state.
