4. Control by eye -gaze
A content of future Internet must be accessible for disabled people.
It is an issue for severely physically disabled people to control a mouse that to browse web pages. Here can help control of computer by user's gaze.
A video-based gaze tracker detects a user's eye and evaluates its angular orientation.
The obtained data could be mapped to the computer screen coordinates.
A click of the mouse is emulated using a dwell time.
