Abstract
A system and method for controlling an eye movement tracker includes monitoring a plurality of eye positions by following a feature using the tracker. An optical beam is sent into the eye, and an intensity of a reflected beam from the eye is sensed at each position. If the intensity of the reflected beam fluctuates from a predetermined acceptable intensity range, the tracker is returned to a frozen position. The frozen position comprises a most recent position at which the intensity lay within the intensity range. The tracker is also frozen if the noise in the signal exceeds a predetermined acceptable maximum noise level and for counting a number of times the tracker is frozen. The procedure is aborted if the tracker is frozen repeatedly and for a time exceeding a predetermined maximum acceptable time.
