Optimizing gaze typing for people with severe motor disabilities

Usability Evaluation of Optimized Single-Pointer Arabic Keyboards Using Eye Tracking

“…As for Arabic language, iWriter was introduced by Al-Wabil et al [17] as an Arabic software keyboard that was designed for use by people with physical disabilities using gaze-controlled text typing. However, eye typing using this keyboard can be very slow since it depends on the dwell time threshold that sets a limit on the maximum typing speed.…”

“…For Arabic single-pointer keyboards, the currently available systems for mobile devices still use the Arabic typewriter's layout. For example, iWriter system [17] embeds an Arabic virtual keyboard using gaze-controlled text typing, but the system's developers highlighted the importance of designing an optimized Arabic keyboard layout adapted for such applications in order to improve as much as possible the text entry performance since (1) eye typing can be very slow due to the dwell time threshold that sets a limit on the maximum typing speed, and (2) it can also lead to eye fatigue and pain when involved in long time computer related work due to the repetitiveness of eye and head movements.…”

“…e iWriter [17] is an Augmentative and Alternative Communication (AAC) system that is operating entirely by eye gaze and that was initially developed to provide alternative forms of communication for people with severe motor disabilities. It includes an embedded Arabic virtual keyboard.…”

“…Advances in Human-Computer Interaction A pilot experiment was conducted in [17] to assess the accuracy of eye fixation and to evaluate the key size. Six participants were asked to type four sentences with different variations in letters using the usually used virtual Arabic keyboard and Tobii X120 device to track user's eye gaze.…”

Mind-controlled augmentative and alternative communication for people with severe motor disabilities

“…She had the chance to try the Emotiv headset and experiment with one of the actions, which she has completed successfully. Also, we were able to observe the participant in using the iWriter [15] which is an eye-gaze Arabic typing system that offers similar functionality to the one we are offering in our system. Parallel functionality for facilitating communication in the gaze-control and mind-control systems was examined and design features that are applicable to our system were noted and considered for adapting to our design.…”
