This paper presents a practical human-computer interaction system for wheelchair motion through eye tracking and eye blink detection. In this system. the pupil in the eye image has been extracted after binarization. and the center of the pupil was localized to capture the trajectory of eye movement and determine the direction of eye gaze. https://www.roneverhart.com/Peavey-KB-1-20-Watt-1x8-Keyboard-Amplifier-p27006/
