True in normal conditions, but our neocortex is highly adaptable. I can’t remember the studies, but there have been cases where a grid of actuators was taped to the body of a blind man and hooked up to a camera mounted on his head. In time, he was able to “see” edges based on the signals coming from his skin.

That's amazing.

I guess probably the orientation didn't even matter. So likely, you could seamlessly wear something like that on a patch of skin that stayed out of your way (on your back, perhaps).

This is essentially how cochlear implants work. Just get a usable signal to the brain (early in life) and let the brain sort out what to do with the information.

It's actually a little tab that the blind person puts on their tongue. Link below.
