An important characteristic of a virtual human is the ability to direct its perceptual attention to objects and
locations in a virtual environment in a manner that looks believable and serves a functional purpose. We have developed a computational model of perceptual attention that mediates top-down and bottom-up attention processes of virtual humans in virtual environments. In this paper, we propose a perceptual attention model that will integrate perceptual attention toward objects and locations in the environment with the need to look at other parties in a social context.
