Study and Application of Detecting Blinks for Communication Assistant Tool

Abstract

We try to develop a support application for physically handicapped children to communicate with others by blinks. Because of limited body movements and mental disorders, many of them cannot communicate with their families or caregivers. If they can use applications in smart phones by blinks, they will be able to tell what they really need or want. Fist, we try to detect an eye area by using OpenCv. Then we develop the way to detect opening and closing of eyes. We combine the method using saturation and using complexity of image to get more accurate results to detect blinks. Then we develop the technique into a communication application that has the accurate and high-precision blink determination system to detect letters and put them into sound.
