At the very least you should do some prototyping of your product (not idea) and do some basic market research. No one wants to buy an idea but they might be excited about a new product that needs their capabilities to bring to market.

Market research will tell you a lot about how the idea might have been tried before.

From my own perspective you sound like you’re describing a partial glove. I believe these have been tried before but maybe there are some new factors that make it more viable. That idea does have traction with artists using touch screens for drawing because it neatly solves their problem.
