Behaviour Coordination of Virtual Agent Navigation using Fuzzy Logic

This paper presents a solution for the behavioural animation of autonomous virtual agent navigation in virtual environments. We focus on developing a fuzzy controller to control and coordinate navigation behaviour. Two behaviours are considered: goal seeking and obstacle avoidance. Two main problems have been identified. These are: how to decide which behaviour should be activated at each instant; and how to combine the results from different behaviours into one command to be sent to the virtual agent. In summary, the proposed solution is simple and is expected to be applied to more complex problems with ease.
