Vision Problems and Eyegaze Edge® Solutions

Vision problems such as diplopia (double vision), blurred vision, alternating strabismus and homonymous hemianopsia (vision field-cut) may impede Eyegaze use. In other cases, cranial nerve damage may limit the individual’s ability to control their eye movements. Eyegaze Inc’s multi-disciplinary approach and technological advancements allow several work-arounds to address these challenges.

These work-arounds are possible because the Eyegaze Edge precisely tracks the movement of one eye with minimal infrared light. In the case of diplopia or alternating strabismus, applying a nasal-side patch to the eye that is not being tracked may solve the problem. This intervention causes one eye to consistently look at the screen, providing maximum gaze point accuracy, without impeding peripheral vision on the partially patched eye. Meanwhile, the individual retains a full field-of-view.

Additionally, the Eyegaze Edge Settings program offers a variety of adjustments that enables an individual to activate an Eyegaze key quickly while providing a short recovery period to give them extra time to move their eyes off a target and onto the next. If the individual has a vision field-cut, customized screens may be created to avoid the area of the screen the user can’t see. Eyegaze Edge users have various choices of keyboards that will accommodate specific visual impairments, including switch scanning and two-stroke keyboard pages.
