1session sequence of actual hand. The persons in these photos are the authors. This figure shows the experiment using his own hand. In this case, the amount of information flow in the brain was 1.6 as the average of all the measurements. In the VR space without visual haptics image the amount of information flow in the brain was 1.2. In the VR space with visual haptics image, the amount of information flow in the brain was 0.7. As one of potential reasons, the real world has even more amount of perceptual information than the VR space for subjects to recognize. This could indicate the difficulties of easily influenced by all inputs from outside and inside of the subject. This kind of experiments should be designed carefully for the other multi modal experiments and meaning of information flow in brain could be deepened through various evaluation experiments.
