A Simple Algorithm for using Face as a Pointing Device using OpenCV

Computer has influenced our life in such a way that it is very difficult to sustain without a computer. For physically challenged persons, especially persons without hands and legs, it is impossible to use the computers without an assistive technology. Keyboard and mouse are the most essential input devices to work with a computer. By the use of on-screen keyboard, a pointing input device such as mouse is sufficient to operate a computer with GUI software. The basic actions of a mouse are Mouse Movement and Mouse Button Click. This paper is on developing an assistive technology that replaces the mouse movement by head movement using OpenCV. The Mouse Button Click is implemented by any facial expression such as blinking eye, opening mouth and head movement.
