Usability and performance of selected configurations of eye tracking sets in augmentative and alternative communication - case study

Abstract

The development of new technologies has contributed to the creation of new tools which enable disabled persons to communicate with their surroundings, including use of internet network resources and education. Nowadays, when so many people have moved their activity, including their professional activity, into the network environment, even people with limited mobility and speech can function actively in society. Applications, which coupled with equipment recording eye movement may provide an aid to improving computer skills, are presented and compared in the paper. Solutions that do not require large financial resources are presented. These are shown to be very valuable, and this has been demonstrated by performance tests and a usability assessment of particular configurations formulated by a user unable to speak and diagnosed with quadriplegic cerebral palsy since the birth. The information provided in the article can be used by persons who want to enable their charges to communicate independently with a small financial outlay.
