Higher dimensional space enhances in intellectual activity of human beings. 3D graphics contains much more information
than 2D graphics. We proposed visual and haptic representation of five-demensional 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 potensial field which indicates
axis of rotation. Usability of the 5D cube is examined through recognition performance tests.
