This paper describes the action generation of an autonomous animated agent. The agent behaves as if it has subjective motivation that is affected by its experiences. A typical study of this generation uses an ad-hoc method for the subjective action because it focuses on the action selection to solve some task. This paper proposes an indefinite communication architecture (ICA) to generate a subjective action. ICA keeps the experiences of an agent using indefinite observation. In particular, since the indefinite observation gives some chaotic feature to the experience, ICA generates various actions in response to an environment. This paper simulates and discusses the behavior of ICA in our interactive system.
