Yeah, this should be researched. How would you produce an analog signal to represent touch semantics?

You ever heard of that paper, *what the frog eye tells the frog brain” (Or something like that) ? It covers what’s effectively semantic information, not bits of data, getting sent over the central nerve. Edges, flashes, …

I wonder what the skin might tell the brain.

I also wonder if there would be a way to bounce a static field, or something, off the surface… maybe vibrate the material, etc,,, to approximate these sort of details.
