Abstract:This paper presents a perception model based on the feedback control for autonomous virtual humans. In this model, the perception constraints of the organs are firstly maintained by the perceptual filters. Then, humans’ memory function is simulated since the circular queue is designed to store the relevant information of the perceived objects. Furthermore, according to the results of the perception and memory, all the parameters of the perceptual filter are controlled by feedback so that the effect of the perceived outcome on the process of the perception is demonstrated. The experimental results show that the perception model based on the feedback control not only reflects the characteristics of the human perception system well, but also provides more authentic environment information for autonomous virtual humans to control their behaviors and make decisions.
