Playing chess against a robotic arm or an interactive surface adds a whole new element to a standard internet chess match. Instead of playing through your complete screen, this DIYer built an interactive board enabling you to play online, but use real physical pieces.
The board was built using a 20W LED low-resolution LCD projector displaying the 64×64 chess grid on the opaque surface of a box. Your moves are logged by a low cost webcam placed inside the box and then fed through visual recognition software and uploaded it to the internet chess server.
As you can see from the video, the internet server relays feedback to the game along with the time which is displayed on the board. he move recognition software and the webcam make this chess project a sort of low cost multi-touch system.
