Abstract

Objective: Nowadays computers are controlled by hand with some tools like mouse and keyboard generally, so people that can't use their hands aren't able to use these tools. This research was aimed to design a system, which help HANDICAPPED people to TYPE by their eye movement.Materials & Methods: In this design, boarder between iris and sclera which is called LIMBUS is tracked with the Infra Red transmitting and receiving system. Then software will process measured values, and will change them to proper values for moving cursor on characters. Since changing the user, unwanted head movements can affect on system operation, a calibration stage is considered which adjust the system in new condition. The system was implemented on 10 subjects (5 women & 5 men) and data were analyzed.Results: Distance resolution of system on 15" monitor's screen is about 4.11±3.38 centimeters. People with no experience can TYPE a sentence with 14 characters in 3:30 minute by 28% error and an experienced person can TYPE this sentence in 3 minute with 13% error. So the system with relatively high repeatability allows the user to communicate with computer by his eye movements.Conclusion: This system is able to recognize 12 points on monitor's screen. Each point is belonging to one character. Facility of using the system and no contact between system and eye are from the benefits of the system.
