Demonstration movie recorded during the initial period of the avatar-control training. In spite of the subject's intention to enter a training course (green path) in the VR (virtual reality), he proceeded in another unintended direction. It can be seen that he wanders in the area with no success of going back to his desired direction.

Demonstration movie recorded during the final period of the avatar-control training. The window consists of two sub-windows on the right-hand and the image of computer monitor on the left-hand. The lower right sub-window shows the subject trying to control the avatar in the monitor. The upper right sub-window depicts the volunteer students participated in this demonstration. They logged in the VR from their university located 15 km away from the subject's home. The subject first tries to reach one of the volunteers' avatars. Although he approaches another avatar accidentally at the beginning, he managed to correct his way and successfully reached the avatar that he intended at first. Other volunteers' avatars consequently came towards the subject's avatar and celebrated the subject's success by cheering, dancing and chapping.
