making agents gaze naturally - does it work?
We investigated the effects of varying eye gaze behavior of an embodied conversational agent on the quality of human-agent dialogues. In an experiment we compared three versions of an agent: one with gaze behavior that is typically found to occur in human-human dialogues, one with gaze that is fixed most of the time, and a third version with random gaze behavior. The versions were found to yield significant differences in efficiency of the dialogues and in user satisfaction, amongst others.
