Sometimes during blitz games over the board, or when in zeitnot, it gets very difficult to annotate them.
I've seen several software / hardware to help in writing the notation, even one that's FIDE approved; these require that you repeat the moves on the device. Hardly faster than pen and paper, just as prone to errors, plus you risk typing the wrong move and wasting even more time.
DGT makes a board that will do this automatically, but it will only work with its pieces, and starts at 400€, double that for tournament boards. Some independent projects are available such as usb chessboard 101, or voice controlled chess robots, Chess board step sequencer. Additionally some open projects are available that even move pieces (or gigantic pieces).
I have a playoff tonight, and the tournament rules dictate shorter and shorter games until there is a winner. Hence I thought about shooting a movie of the board should we lose track. But then my programming background kicked in and I thought "there must be some software that can process a movie and write the PGN".
I searched everywhere, and found nothing.
- Does any such thing exist (webcam/video to pgn converter)? A prototype maybe?
- Has anyone attempted such a feat and shared their research?
- Are there obvious limitations that make this project unlikely to succeed?
- Would you buy it if it existed?
