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.
Technological Implementation
The University of Bristol has developed a method for haptic feedback that could be integrated into a volumetric display. The system uses focused ultrasound to create a haptic objet in mid air.[1]
Feedback
The following feedback can be provided to the user:
- Surface contact
- Surface texture
- Vibration
- Motion-based/topological changes of surface
Previous Work
- Refreshable Braille Display (two dimensional).
- Optacon (two dimensional)
- Wired glove (partial 3D representation).
