Eye gaze system to operate virtual keyboard

For many people who has disability in communication, giving some information to other people is a hard thing to do. To make the communication easier, some people who is not able to speak or has disability in motoric function espescially hand, need a system that can help them to communicate. Based on that condition, in this research a system that can help them to communicate was built. This system used eye gaze to write some information with virtual keyboard. The process are user's face is captured by a camera, then the camera do some feature detection of face to get position of eye gaze, and this position will become a reference of pointer position to choose some word in virtual keyboard. HaarCascade method was used to detect some feature of face, and Integral Projection method was used to get position of the eye movement. Based on the results of the experiment, the comparation ratio between duration of normal writing and typing using system for two words is 1:13 second. With those two words that was typed in this system, user can give an information quite clearly enough.
