In the current immersive VR system, the motion of the virtual body that the user operates is limited to what can be performed in real body, since the natural real body motion is generally used as a system input. Therefore, in this research, we propose the concept of “Motion-Less VR” which is an immersive VR interface that does not require the real body motion. The interface is consisted of the functions which are; sensing joint torque while the real body is mechanically restrained, calculating virtual motion through forward dynamics, and presenting motion information. As a first step, we developed a basic system and potential feasibility was evaluated.

The authors propose a VR system called “Motion-Less VR”, which does not require motion of the real body. In this paper, we developed a system that enables 2-DoF motion of the shoulder and elbow, and basic experiments were conducted.

Immersive virtual reality system has a problem that the operability deteriorates if the shape of the virtual body is parted from the real body. The authors are assuming that this is caused by misfit of the body scheme, an internal model in the brain used to recall the body position, because it is initially tuned up to the real body instead of virtual body. Thus, the authors have proposed a method using VR technology called“ Body Scheme Calibration ”to change the body scheme adapting to the real body so as to fit the virtual body. However, in the previous approach, presented VR information was limited to visual information, and haptic information normally occurring from interaction with surrounding object was neglected. Therefore, this paper investigated the effect of haptic information on Body Scheme Calibration. As an experimental result, it was verified that the effect of additional haptic information is trivial, and the complex haptic interface for this calibration might be omissible.
