Eye tracking the user experience: a practical guide to research. AR can be defined as a system that incorporates three basic features: a combination of real and virtual worlds, real-time interaction, and accurate 3D registration of . The high demand for eye trackers in the healthcare vertical, especially for the assistive communication application is one of the key driving factors for . Existing eye-tracking devices use cameras to capture the reflection of infra-red light emitted to the pupil of the eye and make predictions of selection on a screen. On top of the subjective discomfort, the inability to communicate in an effective manner may impair medical care-for example, by failure to assess symptoms such as pain or breathing discomfort by behavioral cues only. The most notable difference is precision. A car company, for example, can study how changing the design of the dashboard or sightlines of a car can affect driver perception. Here are some of the ways that eye tracking hardware may differ: Human Interface:The most immediately obvious difference between eye tracking devices is in how they interface with the user and environment.

The Tobii Dynavox I-15 eye tracking device (Tobii Dynavox, Danderyd, Sweden; figure 1) and Vidatak EZ communication board (Acuity Medical, Annapolis, MD; figure 2) were employed for this study. Often, people with Cerebral Palsy, muscular dystrophy, Lou Gehrigs disease or spinal cord injuries have little or no control of their hands or feet. This is because, in human-based experiments, some head movement is still possible even in a chinrest or bite-bar. Independence and inclusion is something that should occur 24/7, and we wanted to build a device that enabled users to be more social, she said. Ryan Carter, a Tobii user who participated in beta testing for the I-Series, said the new device has given him options in his life that he did not have before.
