Abstract
In recent years, communication robots are commonly used in various purposes and situations such as guidance services at hotels and stations, elderly support, etc. in Japan. However, it is also shown that people still have a sense of anxiety toward robots. For this reason, there are few people who have motivations to communicate with robots. On the other hand, it has been suggested that the emotional expression of robots contributes to create a sense of familiarity and smooth communication. Therefore, we propose a method of emotional expression and enhancement by changing the color of the clothes the robot is wearing. In this research, we have matched the clothing color with speech emotion for communication robot. As a result of the experiment, we have found the matching between the clothing color and 10 emotions (joy, anger, sorrow, fear, shame, like, dislike, excite, relief and surprise).
