Cooperative ensemble system based on agents

We propose a cooperative performance system based on agents. To realize more intimate cooperation, it is necessary for the system to consider the feelings of a user which reflect his personal taste and mental state. We propose a model of cooperation of the agents considering those feelings. In the model, emotional factors are expressed by mental potential, which is estimated based upon the relation between the agent's behavior and the situation. The mental potential is used for cooperative decision making. A prototype system of creating a musical ensemble was developed for evaluation, and it was confirmed that the users were relatively satisfied in playing music together with the agents.
