Abstract
Research on human interaction is done actively in recently years, and activity of robot is expected in various scenes. For example, the robot which guides facilities while regarding communication as a human being or the robot is intended to play with a child. We paid our attention to the interaction for purpose of enjoying turn-taking. We believe that it is necessary to reflect the preference of the user for an interaction so that a user has a positive impression for the system through such an interaction more. This research aims at development of the human interaction system which a impression for the system of a user improves by the system reflect a preference of the user, and emergence does a better interaction for the user. The user gives an evaluation to the interaction that the user and the system performed, and the system learns it dynamically. The system carries out emergence of a better interaction for a user. This report pays attention to simple interaction by the sight, and inspects effectiveness of the proposal method in interaction using simpler symbol.
