What is it?
Eye-gaze access uses a camera or specialized eye-tracking system to detect where a person is looking and translate eye movements into computer or device control. A user may move a pointer, select items using dwell or another selection method, type with an on-screen keyboard, access AAC, browse digital content, or control compatible applications using their eyes.
How to use it?
Position the eye-gaze system and screen so the learner can comfortably view and access the necessary areas without maintaining an uncomfortable posture. Complete calibration when required and adjust settings such as target size, dwell time, pointer behavior, and selection method. Introduce eye gaze through meaningful activities and allow time to develop familiarity with the system. Evaluate access across different tasks and environments, considering positioning, lighting, fatigue, visual needs, and the difference between intentionally selecting something and simply looking at it.
Why use it?
For learners with significant physical disabilities, eye movements may provide a reliable and efficient way to independently interact with technology. Eye-gaze access can support communication, writing, academic participation, creativity, recreation, and environmental control when direct touch or other motor access is difficult. Effective eye-gaze access can significantly expand opportunities for independent action and self-expression.
