  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'sgaze. • A video-based gaze tracker detects a user's eye and evaluates its angular orientation. • The obtained data could be mapped to thecomputer screen coordinates. • A click of the mouse is emulated using a dwell time.

  5. EYE TRACKING DEVICESLC Technologies EyeGaze

  6. Own build system

  7. Bright pupil and bright glint (corneal reflection) (LC Technologies system) Black pupil and bright glint (own build system)

  8. On screen keyboard

  9. Typing with eyes

  10. ISSUES • High price of commercial eye-tracking systems • Reliability and accuracy of eye tracking • Lack of standarts

  11. EYE MOVEMENT DURING WEB PAGE EXPLORATION
