Eye Tracking as a form of Alternate and Augmentative Communication for people with Speech, Language and Communication Needs

Diagnosing a disease or a condition has become easy and convenient for the clinician, in this digital era. However, the focus on rehabilitative medicine and recovery oriented technology is not as popular as diagnostics. The current trends in eye-tracking involve the tracking of the progression of cognitive disorders in the elderly patients. The tracking of eye motion can give deterministic data about the patient's ability to focus, socially interact, track moving objects (muscle movement), and so on. With the help of eye-tracking, the proposed system helps in designing an efficient system for alternative and augmentative communication (AAC), by utilizing a camera and a screen (with visual prompt display) to determine the accuracy, and speed of response, to categorize the efficiency of AAC method. The system in design can help to improve the latency of patient response and can help to determine the recovery status of the patient.
