Development of Communication System Using Eye Movement Extraction via Image Processing with Blink Detection

Abstract

In this research, a nurse call system for patients with movement disorders by eye movements extraction based on image processing is developed. In the system of the previous research, to extract the human intention, three kinds of iris positions were detected based on image processing. However, the system has a problem that the detection of eye movement with blink did not work well. In this research, a communication system using eye movement extraction based on image processing with blink detection function is developed. The blink contained in images from camera is detected by using the information about the differences of consecutive images. The accuracy of the proposed method was evaluated through experiments.
