I worked on the computer vision aspects of a similar project in
1979-1982. At that time, there were quite a few papers describing
such output devices, with vibrating rods, electrical sensors, even
proposing direct stimulation of the visual cortex ...

A starting point could be: IEEE Trans. Biomedical Engineering,
Special Issue on Electronic aspects of modern prosthesis, 29, 4,
April 1982.

In my thesis, I also had collected quite a few references. It is
available (by regular mail).

Good luck! I hope you will succeed.
