A mathematical model of virtual humans chasing behaviour is set up, the model integrate physiological variables and emotion parameters, emotion synthesis is based on Ekmans basic emotion, some formulas of emotion are constructed, a numerical simulation is realized on PC and the trend of speed, physical strength and emotion are illustrated in some figures.]]>Loomes, G. and R.
