GazeTry

Abstract

Over the last decades, eye gaze has become an alternative form of text entry by some physically challenged people. Recently a dwell-free system has been proposed, which has been proven to be much faster compared to other existing dwell-free systems. However, it is vulnerable to some common text entry problems. In the paper, we propose GazeTry, a dwell-free gaze-based text entry system which allows people to type a word by gazing sequentially at the letters of the word. Simulation and experiments results show that our proposed new dwell-free system, GazeTry with the Moving Window String Matching (MoWing) algorithm has better accuracy and more resilience to text entry errors.
