How plausible would the idea of making a voice-controlled chess set be?
Yesterday, after playing a round in a chess tournament, I thought of the idea of a voice-controlled chess set. Mac has done a voice-controlled chess app, so why not make the same thing, but with a real set? My idea is to have each piece have a board with a railroad-esque track system for the pieces to move around on in response to a voice control unit also incorporated into the set. My main concern was how to circumvent the voice-control mechanism being unable to determine which individual piece to move if more than one of that piece is on the board and capable of the move being made (for instance, if the player said knight to E5, and both knights are capable of moving there, which one does it move?), but then decided that the voice activation could be activated by stating a square name, and the command affects the piece on that square. I know I would have to scale the set up a bit to fit the electronics, but is this idea plausible? How much would the technology to make it cost?
