Eye Tracking and Head Movements Detection to Assist People with Disabilities: Unveiled
Many researchers have been devoted in the past two decades to develop technologies that assist people suffering motor disabilities associated with problems in verbal communication. Eye tracking and head movement detection and their use in empowering people with disability have remained interesting subjects especially in the current digital era. Generally, eye tracking involves manipulation through measuring the eye motion or monitoring the activities of the eye. Various researches have used different methods of eye tracking providing evidence that the science is of value to the society in general, and to the disabled individuals, in particular. Their methods have worked with individuals as well as groups. Head movement detection tracking has been found to be a natural way of expressing direction, and as a control technique it has been shown to be simple and effective. This paper surveys the literature on eye-tracking and head movement detection techniques for helping the disabled group.
