Theres an outfit called Square Off that has made literally this. They were about to deliver a 2nd gen version before covid hit and broke all the supply chains. Its still happening, but harshly delayed.
There's already many solutions for *dedicated* chess boards with electronic outputs -- they're common in major tournaments. (I.e. capacitive sensors under the squares). The point of OP's solution (as I understand it) is anyone can use their own, ordinary boards for this, with no purchase, using standard cameras.
I think it's awesome.
(I think magnetized self-moving pieces exist too, but they're not very impressive. IIRC it's just one 2-dof magnet under the board. But that's slow and more for show than utility. It'd be a handicap for blitz).
I would be wary of using this to play online. I would assume chess.com/lichess anti-cheating algorithms would notice the robotic mouse pattern and eventually ban you.
Really cool, i often use a real chessboard when playing online just to “copy” the moves. looking forward to using this on macOS sometime in the future.
awesome -been wanting to do this for a while, and had an idea to build something like this to automatically record in-person chess tournaments for spectators.
I'm visualizing a board with magnetized pieces and your opponent's pieces would move on their own.
