People with complex communication disabilities along with severe physical disabilities commonly need assistive technology to support access to augmentative and alternative communication (AAC) devices. Eye gaze techniques have become one of the solutions available to solve their access issues. An AAC system that can be used with eye gaze technology usually involves a computer-based device and an eye-tracking device. Although applying eye gaze as an alternative access method for AAC is promising for many people with both complex communication disabilities and physical disabilities, knowledge and skills of the clinician in gathering evidence to decide an eye gaze access is critical to achieve the desired outcome of effective communication. This article will review previous research evidence related to eye-tracking technologies and eye gaze techniques applied with different populations and, then, provide clinical guidance to readers.
