Emotion Interaction of Virtual Character in 3D Artificial Society

In a 3D intelligent virtual environment, multi 3D virtual characters interact with emotion and construct a 3D artificial society. Modeling emotion interaction is a challenging topic for virtual artificial society. Nonverbal emotion interaction is a direct communication manner for virtual characters. A cognitive model of virtual character is presented. A 3D virtual character has a cognitive architecture with built-in knowledge that control emotion and the response to outer stimuli. Some new concepts on nonverbal social interaction are set up.
