Basic Study on Rotational Manipulation Type Redirection Considering Consistency of Body and Environment Junya Mizutani*1, Ryohei Nagao*1, Keigo Matsumoto*1, Takuji Narumi*1, Tomohiro Tanikawa*1 and Michitaka Hirose*1 Abstract - In virtual reality (VR), there is a technique called redirection that enables to expand a limited real space into a large VR space. It had been proposed that it is possible to manipulate spatial perception more effectively by adding haptic cues. However, with this method, since the positions and shapes of the objects in the VR space and the real space are different, misalignment occurs in the positional relationship between the body and the environment when a part of the body is displayed. On the other hand, human spatial perception is classified into a personal space, a peripersonal space, and an extrapersonal space according to the distance from the body, and it is said that the perception characteristics of each space are different. Conventional redirection mainly manipulated the extrapersonal space, we devised an operation method suitable for peripersonal space and thought to solve the problem caused by the method of adding haptic cues. The results from our experiment, it indicates that the proposed method can effectively manipulate the spatial perception than the conventional one. redirected walking, rotational manipulation, body-integration, visuo-haptic interaction.
