I recall reading years ago that researchers had aimed high-speed cameras at grandmaster's eyes when they played chess, and the things that they looked at were different than patzers. Has anyone done the same with go? |

Has anyone done the same with go? I heard that some research has been with tsumego, but it may have been with amateurs. Anyway, the good L&D solvers looked at potential eye points, while the bad solvers looked at where to put stones.

would be fun to try this yourself. I did a quick search for some eye tracking software that can use a webcam as input. I did find one that woks good for me, It woks fine in callibration mode. Unfortunately I have no idea how to make the program work so I constantly see a dot on the screen where I look. (to be able to solve tsumego, or play a game and see where i look) the one I found is called gazetracker 1.6 edit. found the problem. I'll give it a try tomorrow. and post the results if possible |

as promised I made a video of me trying this out. Here is a link on youtube It is not really accurate enough to get a good idea of the exact intersections, but gives some idea. apparently I mostly look at the internal shapes and cuts. when you see me looking to the left it is to check if it's B or W to play, or read some other info about the problem. It will work much better with full screen on a 9-9 board. but this was just a test. I is also fun to see where you look when watching a movie. This does not need great accuracy, but is a lot of fun. conclusion: Not very usable for accurate tracking of individual coordinates on a big board, but great fun for a few $$. |

What software are you using to record the screen zoomed in like that? It looked smooth when panning over the screen. |

Camtasia Studio. The zoom feature is automated. normally I turn it off, but I forgot. This was a quick test anyway Because it looked nice, I did not bother to take (edit) it out again. |
