Webcam Based Eye Interactive System for Locked-In Syndrome Patients
Emmanuel Kwame Effah, J. A. Addo · 2016
Locked-In Syndrome (LIS) patients cannot move nor talk but in most cases have the ability to blink and move their eyes. This project harnesses the blinking abilities of LIS Patients from a live video stream as a way of interacting with a computer system. Farneback’s optical flow image processing algorithm is applied to the frames of the video stream to read blinks. Face detection technique is employed just to increase the probability of detecting the eyes in a frame. The various input gestures (short and long blinks) are used to trigger corresponding events to execute a particular action. The resulting system can be used in the home and in any favorable environment where there is enough light. The system will help LIS patients to communicate, improve the quality of life of LIS patients and immensely widen the area of Human-Computer Interaction (HCI). The mammoth novelty of this paper is the fact that we deployed the ubiquitous Webcam accessory of the Computer Keywords: Locked-In Syndrome; Live Video Stream; Farneback’s Algorithm; Face Detection; Input Gesture; Human-Computer Interaction, Blink.
