    Hello. I have 4C Eye Tracker (works very nice by the way) which I prepare for tile based RPG game. I had compiled EyeX sample, started calibration from program, and everything works well, up to player moving head.
    When the player holds head still he is able to pick small tiles and moves are flawless. But when he moves head the X,Y coordinates drifts (small movements up/down results in about the same drift in Y from gaze data). I thought that after calibration the head movement is compensated internally.

    So my idea was to retrieve distance from calibration and recalculate the position, but I cannot find any helpful data provided by EyeX, like coordinates X,Y,Z of eyes during calibration.

    Is there any API I am missing or workaround to include head moves into X,Y data on screen?
