Use of eye tracking technology among individuals with multiple disabilities and severe communication difficulties

Individuals with multiple disabilities often have profound intellectual impairments and limited/no speech. They often hey communicate with their eyes, mimics and body language. The aim of this clinical project is to evaluate the use of eye gaze technology in individuals with multiple disabilities. We use eye-tracking glasses, a screen-based (remote) eye-tracker and  computer games to investigate cognitive processes among this group of individuals with profound intellectual impairments.

We measure perceptual speed when a person use his/her gaze to flow balls at the bottles.
