Abstract: In this research work we have developed a tool and a program that can be used to replace the behavior of a mouse. Our results have shown that it can be used successfully to replace a mouse that is usually operated by hand. The system we developed in this research can be used to help people with quadriplegia (paralyzed) to operate a computer. In order to be highly accessible and affordable, the tool we built should be inexpensive and can be purchased easily. Thus we have selected an input method using a series of LEDs and a webcam. There are two LED used on the circuit due to the need to have two light sources in order to replace the mouse behavior. The image captured by the webcam is then filtered using an image segmentation technique (thresholding). The first light source is used as the head-tilt detector that will be used as the replacement for the left-button and right-button of the mouse. The second light source is used as a head-motion detector, to replace the mouse movement. Our head movement tracking device uses two pieces of LEDs, wires, several resistors and energy source (battery).

Keywords: Head movement tracking device, image segmentation, mouse controlling, thresholding.
