視覚と力覚を用いた5次元空間のナビゲーション

Higher dimensional space enhances intellectual activity of human beings 3D graphics contains much more information than 2D graphics. We proposed visual and haptic representation of five-dimensional space. Our 5D space is generated by scanning 3D cube. The user's hand can essentially move in 3D space. We therefor use rotational motion of the hand for scanning 3D cube in 5D cube. The 3D cube is cutting volume of the 5D cube. The cutting volume moves by rotational motion around roll and pitch axis of the user's hand. Force display presents potential field which indicates axis of rotation. The user can easily separate rotational motion from translational motion by force feedback. Usability of the 5D cube is examined through recognition performance tests.
