要約(日本語): This research conducts a comparative experiment using a cognitive behavior called “Reaching” to investigate a difference of human cognitive behavior (in other word, ecological cognition) in VR using HMD and the real environment and to examine a method to compensate the difference. First, a subject estimates the longest distance to a cylinder placed in front of the subject at which the subject can reach the cylinder. After that, the subject grabs the cylinder and places it as far as possible. The result is investigated in the real and the virtual environment. In the real, it has been found that the longest distance to an object for a person to decide to be able to reach for and grab the object is about 1.1 times as long as the longest distance where a person can actually reach for grab the object. On the other hand, this research shows the value in the virtual environment is not the same as one in the real. Especially, in the simplified VR environment, a standard deviation of the value among subjects is larger. And it is also shown that the standard deviation in the simplified VR environment without the virtual environment experience tends to be more larger. The results suggest the amount of environmental information and experience of the virtual environment may influence the ecological cognition in VR.
