Tracking pro eye movement

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?

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.
