Eye-motion detection system for mnd patients

Abstract

This paper aims to develop an eye-motion based communication system for motor neuron disease (MND) patients to contact with care providers any time they want when they lie on the bed. This eye-motion detection system involves technical modules of eye-blink detection, gaze estimation and head pose estimation on MND patients. The system comprises a rotating arm with a camera, an infrared light source and a speaker. The arm with the camera will autonomously rotate to track the face of the patient with arbitrary body directions so that necessary eye detections can be properly conducted when it is called. When the patient needs to call out, only designated blinking and eye motions will trigger the call out action for the need of finding the care provider.
