Survey on “Automatic Cursor Movement with Eye Gaze Tracking

The eye has a lot of communicative power. Eye tracking is a process for measuring eye position and movement, and gaze tracking is used to estimate a user's point of regard. These techniques have been widely used in human–computer interaction. Eye tracking system is a communication and control system for people with physical disabilities. It is a technique that acquires and analyzes the eye movements and use it to determine where user's attention is focused through his eyes which can be used to manipulate the cursor position relative to the position of the user's eye on the screen. Eye movement tracking is used in navigating the computer screen without the need for mouse or keyboard input. In this paper, provide an introduction to eye tracking technology and gaze estimation approaches. We also discuss and key features of different eye tracking systems to find the best system for each task
