A Survey On Human Eye-Gaze Tracking "EGT" System:, A Comparative Study

Eye-gaze tracking system research, which has been field active since the beginning of last decade and entered in most varied applications. An eye-gaze tracking system depends on tracking the movement of the eyes to know the precise point at which the individual is looking and for how long. It also includes software algorithms for image processing and computer vision, pupil detection, data filtering, and recording eye movement. Realtime gaze-based content can also be an easy way to hold correspondence and control to a human with disabilities. In this paper, a comparison was made between the techniques used to detect the human eye gaze and the results show that the use Nonintrusive methods based on video easier and not expensive when Compared to other techniques especially used the single camera in the modern mobile devices.
