Eye tracking: Eye-gaze technology

Abstract

With ongoing advancements in eye-tracking technology, more individu-als with complex communication needs (CCN) and who have limited arm and hand movements are exploring the use of eye-gaze technology for accessing their augmentative and alternative communication (AAC) devices. This chapter outlines the various factors that need to be taken into account when evaluating an individual’s ability to use this technology; many of these relate to the roles and functions of an occupational therapist as a member of a multidisciplinary team. Clinical research examining the suitability of eye-gaze technology for various populations is limited; documentation of its effectiveness is based on individual’s testimonials or reports. A case study highlights the role of the occupational therapist in conducting eye-gaze trials with a girl with Rett syndrome.
