Emotions perceived from motions by human, animation and robot

Service robots are becoming popular nowadays. Prior studies related to service robots have mainly examined about appearance, facial expression, voice, gesture and motion. However, it is not clear which characteristics of service robots have an effect on affective interaction most and how they work together. This study aims to study the effects of motion media, motion size and motion velocity on the emotions invoked by the motions. The experiment was designed with 3 independent variables (motion media, motion size and motion velocity), and perceived emotions as a dependent variable. 30 participants took part in the experiment, and the results indicate that the small size of motion is preferred than the large size of motion when the motions are performed by animation and actual robots, in terms of ‘favorable’ and ‘enjoyable’ emotions. These results provide a guideline for designing the motions of service robots.
