Abstract:
A relative position based eye tracking system includes a light source to illuminate a portion of the eye and an optical sensor to capture a sequence of samples of the portion of the eye. The system further includes a sample comparator to compare two samples and a relative position calculator to calculate a change in the position of the eye based on data from the sample comparator.
