EyeK: an efficient dwell-free eye gaze-based text entry system
Over the last three decades, eye gaze has become an important modality of text entry in large and small display digital devices covering people with disabilities beside the able-bodied. Despite of many tools being developed, issues like minimizing dwell time, visual search time and interface area, eye-controlled mouse movement stability etc. are still points of concern in making any gaze typing interface more user friendly, accurate and robust. In this paper, we propose EyeK, a gaze-based text entry system which diminishes dwell time and favors to mitigate visual search time. Performance evaluation shows that proposed interface achieves on an average 15% higher text entry rate over the existing interfaces. As designed, the proposed interface can effortlessly be suited in medium-sized display devices like Tablet PC, PDA etc. Also, the developed system can be used by the people with motor disabilities.
