After a brief description of the perception action principles with a few simple examples, we emphasize the concept of virtual sensors for virtual humans. In particular, we describe in detail our experiences in implementing virtual vision, tactile, and audition. We then describe perception-based locomotion, a multisensor based method of automatic grasping, and vision-based ball gamessoftware agentsvirtual realitytext::conference output::conference proceedings::conference paper
