Mouse Cusor Control Using Facial Movements - An HCI Application

Abstract

Because of various limitations, some people are unable to operate computers. Cursor controls based on facial expression are extremely useful not just for the future of natural input, but also for the handicapped and disadvantaged. Furthermore, creating a control system allows them to operate computers without the assistance of a third party. While this is not an issue for a healthy person, it may be an insurmountable barrier for persons who have a limited range of motion in their limbs. In these instances, input techniques based on the region's greater skills, such as eye movements and facial expressions, would be preferable. A system was created that uses a low-cost way to permit alternative input methods like controlling a mouse cursor on a computer screen. Using a camera we can capture the image of the eye and head movement. The mouse cursor is controlled by head movement as moving face up, down, sidewise movements and mouse events such as right and left click are controlled through eye blinks and squinting. This system is mainly aimed at disabled people to have effective communication with the computer. It is quite beneficial to implement a controlling system that allows them to move without the assistance of another person.
