Volumetric haptic display (original) (raw)

A volumetric haptic display (VHD) is similar to a (visual) volumetric display, but informs touch instead of vision. A VHD projects a touch-based representation of a surface onto a 3D volumetric space. Users can feel the projected surface(s), usually with their hands. The display is otherwise not detectable, and offers no visual feedback. There are no known instances of a fully operational VHD at this time.
