The first part of the problem is to find a set of nerves on/in the body
which can be used to "see". The fingertips are sensitive, but very small.

I would try the skin on one of my thighs, it is fairly easy to attach a
thin elastic cloth around it and leave it on all day.

Then I need a way to excite the nerves in the skin of my thigh.

200*300 points, or more, on the inside of the cloth will excite the
nerves and create a picture which wraps around my thigh, and I use the
nerves in the skin to "see" it.

The idea about electrostimulation fits well into this device.
I would simply try different combinations of frequencies and currents
until I found a setting which gave the best "image" without being painful
in any way.
Mechanical stimulation is also possible, but would be a little more
difficult to manufacture.

A small videocamera can be hidden below or above my own face, in a
band around my head, like a tennis player's sweatband, for example.

So I would feel with my thigh what the camera sees.

With some training it could become really useful.
