Review on Automatic Cursor Moving and Clicking of PC with Eye Gaze Tracking

Now a days for computer we are using input devices such as keyboard, mouse and joystick. With the advancements in the field of Human Computer Interaction, eye tracking or iris tracking is the most promising field. It will fundamentally change the way we interact with computers. In the last decade, the development of eye tracking (ET) systems represented a challenge for researchers and different companies in the area of IT, medical equipment or multimedia commercial devices. An eye tracking system is based on a device to track the movement of the eyes to know exactly where the person is looking and for how long. It also involves software algorithms for pupil detection, image processing, data filtering and recording eye movement by means of fixation point, fixation duration. The main aim of this proposed work is to develop a low cost application running, to replace the traditional computer mouse with the human iris for cursor movement. The target audience majorly consists of handicapped people or people with physical impairment. The system designed aims at detecting the user's eye movements for navigating the cursor, analyzing the nature and timing of blinks, which in turn is used as an input to the computer as a mouse click. The system should consists of a good resolution webcam.
