  • 1. A SUBMITTED TO : PRESENTED BY : Er. DEEPESH NAMDEV GEETA KHATRI HOD (EC & EE) ROLL NO.- 10EGKEC062 P R E S E N TAT I O N ON EYEGAZE COMMUNICATION SYSTEM Gurukul Institute Of Engineering And Technology Rajasthan Technical University, Kota
  • 2. CONTENTS  Introduction  Working  Running  Functions  Operational environment  Advancements  Conclusion
  • 3. INTRODUCTION  This operates with eyes by looking at control keys displayed on a screen.  By looking at the control keys on screen a person can synthesize speech, control his environment, operate a telephone,access internet etc.
  • 4. USERS OF EYE GAZE SYSTEM  Eye gaze Systems are in use around the world. Its users are adults and children with spinal cord injuries, brain injuries etc.
  • 5. WORKING As a user sits in front of the Eyegaze monitor, a specialized video camera mounted below the monitor observes one of the user's eyes. Nothing is attached to the user's head or body.

To "press" an Eye gaze key, the user looks at the key for a specified period of time. The gaze duration required to visually activate a key, typically a fraction of a second, is adjustable. An array of menu keys and exit keys allow the user to navigate around the Eye gaze programs independently.
