Research on Virtual Emotional Human System

Virtual emotional human system (VEHS) can be widely applied in game role and computer interface performance enhancement. Artificial emotion, as a branch of AI, is aimed at endowing robot with various emotions such as sorrow and happiness. So it becomes a more and more attractive research field than before and will be an advanced stage for AI. The research frame of (VEHS) is represented in this paper. And the emotional model, method and realization technology are also investigated. The model was set up combined six dimension emotional space with hidden Markov chains, which can be trained by the verbal and nonverbal information from a multiple databases. Furthermore a rudiment of VEHS was formed based on this model and evolved later from the communication with outside gradually. A simulation has been developed and the results are encouraging. It is expected to be applied into the interface between human and machine in the future.
