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
