Abstract: In design of modern computer games, it’s very important to model a virtual human with believable perception behaviors. In previous researches, the range of a perception system is always unchangeable. An adaptive perception system based on Q-Learning is proposed, a virtual human confirms the range of a perception system dynamically according to his appraises to the objects in the environment. A demo system of a virtual human searching for specific herbs is realized on PC. The results show that the model can drive a virtual human to have believable perception behaviors.

Key words: Virtual human, Perception, behavior animation, Q-learning.
