A new input system for disabled users involving eye gaze tracker and scanning interface

Purpose – This paper aims to present a new input interaction system for people with severe disabilities. The new system works based on eye gaze tracking and single switch scanning interaction techniques. It combines eye gaze tracking and scanning in a unique way which is faster than only scanning‐based systems while more comfortable to use than only eye gaze tracking‐based systems, which is also supported by a user study.Design/methodology/approach – The aim was to design a new interaction technique combining eye tracking and scanning technique for severely disabled people. A comparative study with eight users involving only an eye tracking system and the system combining eye tracking and scanning was conducted.Findings – The participants rated the new system easier and less strenuous to use than the eye gaze tracking‐based system, while the new system did not slow the speed of interaction.Originality/value – This new method based on eye gaze tracking and single switch scanning interaction techniques has ...
