Volumetric Haptic Display

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).
gollark: Note the e (it is a pun).
gollark: Minoteaur. It's a graph-structured wiki-styled web-based note-taking hyphen-using application.
gollark: It's a Greek-mythology monster in a labyrinth somewhere which ate people a lot.
gollark: Because instead of "pages have attached files which can be linked the pages", you could just have "pages contain files as a separate type of content, embedded appropriately".
gollark: Minoteaur 7.1 had file management capabilities, but while working on this now I realized I suddenly realized that this could probably be combined with the content model rework somehow, accursedly.
