Somepeoplehavehealth-relatedconditionsthatimpedetheir utilization of computers. In that regard, it is
quite necessary to come up with redesigns for effective use of computers that meet the requirement of
people living with disability. The human eye can be considered as a promising replacement of standard
input devices. This paper presents a web camera as an option with which a person would control the
cursor by moving the eye. For the pupil detection, we use OpenCV, so the eye frames obtained would
be sequenced for the purpose of controlling the movement ofthemouseonthescreen. Also, Eye Aspect
Ratio (EAR) is computed for determining the gaze movement, i.e., lateral movement of the left or right
eye using the OpenCV library under Python programming. This particular method aims to optimize the
computer environment in the very focus of those with physical challenges by providing them with a way
to control the computer without using for instance a mouse.
