旋回ゲインを用いたリダイレクテッドウォーキング

抄録

A method called redirected walking has been proposed to enable users to walk in a real space of limited size in a vast virtual space by manipulating the user’s direction and amount of movement. Three viewpoint manipulation methods, namely translation gain, rotation gain, and curvature gain, are mainly used in redirected walking. The rotation gain manipulates the user’s direction of travel by manipulating the rotation around the user’s head. However, when the rotation gain is applied to a user walking around a turn, the user’s walking path may deviate from the target. This deviation of the user’s walking path would be a serious problem, especially when interacting with real objects. To solve this problem, we propose a novel turning gain and correction method, which can control the user’s walking path even when the user turns without stopping.
