Research and realization on real-time linear prediction algorithm for Desktop Eye-Tracking

Eye-tracking as a new method of human computer interaction has the merits of naturalness, efficiency and easy intent understanding. The authors have designed a Desktop Eye-Tracking System which used the technique of image processing to obtain the user's gaze focus in virtual environment scene. Based on the theory of pupil center corneal reflection, the authors improved and realized a highly efficient linear prediction algorithm for real-time eye gaze image processing. Experiments proved that this algorithm can well support real-time eye-tracking as an interaction modality for desktop virtual environment.
