Providing Educational Accessibility for a Paralyzed Student by Eye-Tracking Technology: A Design-Based Research Study

This study explores the development of an eye-tracking solution for paralyzed students, enabling them to access and utilize personal computers for their education. It relies on eye-tracking technology, enabling computer control through eye movements. The study followed four phases: problem analysis, solution development, evaluation, and documentation. In the analysis phase, the problem for developing a solution was defined based on the interviews with the instructor, the paralyzed student, and his parents. The iterative and incremental development process was followed in the development phase with four development cycles. At the end of this phase, an eye-tracking-based computer control system and design principles were obtained to develop such a system. During the evaluation phase, paralyzed student used the system for two semesters. The final phase documented design principles for further eye-tracking systems to support paralyzed individuals' academic lives. By adhering to these design principles, there is a need to develop and adapt more solutions and systems for the benefit of paralyzed people, enabling them to access and maintain their academic lives. The study highlights the potential of eye-tracking technology for paralyzed students and promotes the development of similar solutions.
