A study on text entry methods based on eye gestures

Purpose – The purpose of this paper is to consider the two main existing text input techniques based on “eye gestures” – namely EyeWrite and Eye-S – and compare them to each other and to the traditional “virtual keyboard” approach. Design/methodology/approach – The study primarily aims to assess user performance at the very beginning of the learning process. However, a partial longitudinal evaluation is also provided. Two kinds of experiments have been implemented involving 14 testers. Findings – Results show that while the virtual keyboard is faster, EyeWrite and Eye-S are also appreciated and can be viable alternatives (after a proper training period). Practical implications – Writing methods based on eye gestures deserve special attention, as they require less screen space and need limited tracking precision. This study highlights the fact that gesture-based techniques imply a greater initial effort, and require proper training not only to gain knowledge of eye interaction per se, but also for learning...
