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.
