Scale conversion telexistence is an extended concept of telexistence. It comprises avatars of different scales compared with the human scale. Immersive telexistence experience requires the avatar to realize the operator's behavior instantaneously as soon as possible. It is important to match the avatar's behavior with the operator's behavior because the difference between the operator and the avatar tends to hurt the immersiveness. However, the scale difference between an operator with the avatar makes behavior mismatch and lets the operator experience under different physical constant world. For instance, gravity changes under scale conversion telexistence. Therefore, our previous work reveals its importance termed equivalent gravity condition for walking using a small biped robot. Thus, in this demonstration, we use a small biped robot as the different-scale avatar allow us to experience as if we are within the small robot. Attendees experience several steps walking under different gravity conditions.
