The manipulation of objects is fundamental to virtual reality applications. Better methods are needed to grab and manipulate virtual objects by moving one’s hands in 3D space. But the anatomical complexity of the human hand makes it very difficult to accurately track manual motions. Haptic technology, which recreates the sense of touch by applying forces, vibrations, or motions to the user, provides cues in object manipulation. Haptic interfaces are essential in order to generate sensations relating to touch and effort. Active hand mounted devices make it possible to accurately track the hand and feel virtual objects with the fingers but they are complex and costly.
