Robot’s communication function is important for coexistence of robot with human. Recently, several research have been conducted to facilitate the communication between robot and human. In this paper, the visualization of robot’s utterance information was proposed as a way to convey robot’s intention more clearly as well as increasing human’s subjective evaluation about the robot, utilizing a dialogue projection system. In this system, after the talk of the robot, some words from robot’s talk was projected on the wall behind the robot by a projector. In order to verify the performance of the proposed system, a comparative experiment was conducted under three conditions: projecting, subtitling and not showing the information of the robot’s talk. The result of the experiment showed that subtitling the talk information improves the subjective evaluation of human about the robot.
