DESCRIPTION:This is a talk I'll be giving at the Graphite2005 conference n
 ext month.\n\nPaper abstract: We describe a system designed to improve the
  simulation of human crowd behaviour by considering the visual perception 
 and attention of each individual in the crowd. All of our techniques are b
 ased on psychology research\; the ways this has been used are explained in
  detail. Our system runs in real-time\, allowing quick experimentation wit
 h different ideas. The attention shifts for each actor\, along with the as
 sociated gaze shifts\, are controlled by a set of communicating agents. Th
 e agents can make requests for shifts of gaze and a gaze control agent sor
 ts these according to priority. In our system each actor builds its own me
 ntal model of the world\, based on its monitoring of other actors in the c
 rowd. We argue that because we are using only the limited information from
  this mental model to decide the actor's behaviour\, our simulation produc
 es more realistic behaviour than previous work.
