    Hallo Deutschland

    I'm very near of the final result but i don't have enough time in hands to continue my work straightforward.
    I also had to abandon the idea of getting pupil movement in relative position to the head, this is damn too complex to handle and would require much more than a M10000 to calculate.
    I adopted another way of filtering which is even better than contours estimation. When the tracking is locked it remains locked regardless of the eye speed and direction.

    Apart of this i have the code to make the bridge between eye moves and cursor moves, need a little time to make the junction with those two codes and that's it

    So here is the video, the first minute is garbage as my camera was not aligned to the screen, sorry

    As it could be difficult to understand what happens in the video, you will notice the pupil is very dark (black), in it's original state the pupil density is not so high and the tracker with a threshold level can adjust this density. A fine adjust can make the tracker to not take the background, we also do not rely on the infra-red reflections which would always be out of the center of pupil so they would make false data.

    I found this link after reading about what you've been working on, and thought it might be useful.

    Hello

    Nice to see that some are interested with this attempt to make a gaze tracking thingy
    Thank you to mention the link, the hardware part is ok, still the software part can't work.

    I'm aware about this link for the software part as well ( any optics guru here ? ) but unfortunately it is not usable as is because everything is too much outdated inside.
    It relies on OpenCV ver 0.9.5 which can't compile on recent environment. Except if you feel that you can convert the whole cvEyeTracker to make it work with OpenCV 1.0.0 with recent glibc and recent kernel, i'm afraid it will remain as a nice example of what can be done
