Electrooculography based assistive technology for ALS patients

Abstract

This paper describes an Assistive technology for ALS patients that is controlled by Electrooculogram signals (EOG). In situations of traumatic diseases or paralyzed conditions, the patient may lose the ability to communicate with others by speech or gestures. In most cases, the only remaining and active capability for patients suffering from neurodegenerative disorders are the eye movements. The human-computer interface provided is controlled by the eye movements of the patients. Using various eye movements, the individual can control the interface in order to communicate with others or request the help of the caretaker in cases of need and emergency. The use interface and virtual keyboard provided may be used to examine the performance and usability of the proposed assistive technology.
