A Model for Virtual Emotional Human System

An ultimate aim of artificial intelligence (AI) research is to endow machines with human intelligence, such as reasoning and decision-making. 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 the virtual emotional human system (VEHS) is represented in this paper. And the emotional model, method and realization technology are also investigated. The model was set up combined with six dimension emotional space and 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
