Vinayagamoorthy, V.Garau, M.Steed, A.Slater, M.2015-02-192015-02-1920041467-8659https://doi.org/10.1111/j.1467-8659.2004.00001.xThis paper describes a behavioural model used to simulate realistic eye-gaze behaviour and body animations for avatars representing participants in a shared immersive virtual environment (IVE). The model was used in a study designed to explore the impact of avatar realism on the perceived quality of communication within a negotiation scenario. Our eye-gaze model was based on data and studies carried out on the behaviour of eye-gaze during face-to-face communication. The technical features of the model are reported here. Information about the motivation behind the study, experimental procedures and a full analysis of the results obtained are given in [17].10.1111/j.1467-8659.2004.00001.x1-11
