Virtual reality technology provides a new role of human-machine interface. In the virtual space, it is important that we cannot only perceive a spatial environment but also manipulate objects as we will do in the real space. In order to realize a virtual environment, it is necessary to investigate the relation between sensory system and motor system. Because it is natural that we usually interact with anything in the real space as well as we perceive the real space passively.
In this paper, we investigate the influence of visual stimulus on the hand movement induced visual stimulus. We use two visual stimulus in the experiments. One is a “Target” which subject is instructed to hold. Another is a “Reference point” that is presented as an additional stimuli with a “Target”. These two visual stimulus cannot be touched because of mirror images.
We assessed the pointing error to the target as the accuracy of space perception. The results revealed that in the case of presenting a reference point, the pointing error becomes smaller than in the case of presenting only target. Especially, this tendency is more effective on the target near the reference point.
Our findings suggest that visual stimulus near the target give the information to perceive more accurately the target position.
