Users' Opinions When Drawing with an Eye Tracker.

Eye tracking is interwoven with the research in the field of Human-Computer Interaction as a tool that examines the user’s visual attention in their interactions with computing devices and can reveal behaviors and factors that could otherwise remain unnoticed. In this paper, we take a novel approach by examining the use of an eye tracking system as an input method by developing a drawing application that the users can draw with their gaze. The application was developed to address the need for drawing software accessible to all individuals using commercially available and affordable hardware. An evaluation experiment (n = 25) was conducted, with results showing that although participants felt drawing with their gaze had a degree of difficulty, they enjoyed the experience and thought that drawing with their gaze was an exciting and fun experience. Furthermore, comments were made that could constitute a meaningful improvement for future application iterations. Finally, a longitudinal study showed that users’ drawing skills markedly improved each time they used the application while also feeling more inclined to use it daily.
