Volumetric Haptic Display
From Wikipedia, the free encyclopedia
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.

[edit] Technological Implementation
At this time, there is no set method to implement VHDs, but it is likely that a wired glove will be used. Methods of projecting the tactile information into space are still being developed.
[edit] Feedback
The following feedback can be provided to the user:
- Surface contact
- Surface texture
- Vibration
- Motion-based/topological changes of surface
[edit] Previous Work
- Refreshable Braille Display (two dimensional).
- Wired glove (partial 3D representation).
