Figure. Electrode muscle placement for electromyogram cursor control system.

Individuals with disabilities, such as persons with amputations or spinal cord injuries, who cannot use the computer keyboard or mouse face limitations in interacting with computers and accessing the benefits of computers. Some of these individuals may use eye-gaze tracking (EGT) systems to control the computer cursor. However, these systems may lack stability and accuracy, and users may find performing correct "clicks" on small icons difficult. This article describes a system that uses EGT input for long cursor movements while detecting the contraction of four facial muscles to provide more accurate and reliable small cursor adjustments and reliable clicking.
