Advanced Eye Tracking Technology: The Lifeline Of A Disabled Person

NEW YORK CITY, N.Y. – Amyotrophic lateral sclerosis, more commonly known as ALS, is a kind of disease that affects the motor neuron. More or less 80 percent of ALS patients have difficulties in communication, strokes, spinal cord injuries, cerebral palsy, and multiple sclerosis.

Eye-gaze devices enable some people, especially ALS patients that suffer from restricted speech or hand movements, to paint, utilize environmental controls, communicate, and compose music.

The movements of the person’s pupils from the light reflection captured by the camera from the user’s eye are transformed into movements of a screen’s cursor. This is the one that selects either symbols or letters by the use of infrared technology. A device that generates speech then translates written words into actual speech.

Eye gaze technology advanced quickly with solid NHS funding, options for lower cost, and better accessibility. Prototypes invented just recently have instilled the same technology into glasses and smartphones.

Peter Desain, the chair of artificial intelligence at Donders Institute for Brain, Cognition, and Behavior at the Netherlands is the process of studying brain-computer interfaces (BCI). This is a technique that analyzes the signals sent by the brain and uses it as a control for certain devices.

Meanwhile, the NoiseTag method of Desain developed at Radboud University Nijmegen lets the user wear an electrode-fitted headset that keeps track of brain activity. The user focuses his vision on a certain character from a given set. The focus given to the character enables a signature to materialize in the form of brainwaves which is then saved by the headset. The chosen character that is typed will then be spoken in a complete sentence by a device.

Eye tracking remains a significant technology that assists people with disabilities. For people struggling with a disease that renders them incapable of movement and speech, technologies for communication is not about refined brain advancements. It is just basically about existence.
