The impact of avatar realism and anonymity on effective communication via mobile devices

This research investigates the impact on social communication quality of using anonymous avatars during small-screen mobile audio/visual communications. Elements of behavioral and visual realism of avatars are defined, as is an elaborated three-component measure of communication quality called Social Copresence.
