Abstract

<p>A small (cellphone size) human-like robotic avatar in tele-communications will be a novel portable communication medium in that a user can talk with another person while feeling the other's presence at anytime, anywhere. The human-like robotic avatar is expected to express human-like movements; however, there are technical and cost problems to implement actuators in the small body. This paper proposes an idea to illusorily move the avatar's extremities with blinking lights. This idea needs only LEDs (Light Emitting Diodes) and avoids the above problems. This paper designs a LED blinking pattern to invoke a nodding motion of a hand-held tele-operated humanoid robot. A psychological experiment shows that the designed blinking pattern gives better impression to subjects than an symbolic blinking pattern. This result suggests that even the illusory motion of robotic avatar can improve tele-communications and it is suitable for human-like robotic avatars with respect to a minimally human-like motion expression. </p>
