Touch input and gaze correlation on tablets

Prior work has shown gaze behaviour correlates with mouse movement in conventional desktop interfaces. As many devices now employ direct touch instead of a mouse, we have conducted a first study analysing how gaze correlates with touch input. We collected touch and gaze data on a tablet from 24 participants, on search, shopping, and ``link-following'' tasks representative of typical online use of tablets. Our analysis shows a gaze fixation typically leads touch input by 337 ms within 197 pixels. We observed a stronger correlation in the context of link-following, in comparison with touch on other HTML objects and virtual keyboard
