The Eyegaze Edge is also able to accurately predict their gaze point at indirect angles to their face, meaning they can operate it even if they are leaning to the side, without changing the angle of the screen. For many individuals with CP this feature is extremely valuable, often eliminating the need to constantly re-position the screen or recalibrate the Eyegaze system.

A variety of eye movement problems are also often associated with CP, most commonly alternating strabismus. It may be necessary to partially patch one eye for accurate use. For those who have uncontrollable head motion beyond available wheelchair supports, they may not find Eyegaze operation always acceptable.
