Abstract

The problem of triggering input accurately (with a small temporal offset) and precisely (with high repeatability) at a specific point in time has so far been largely ignored in gaze interaction research. We explore voluntary eye convergences as a novel interaction technique for precise and accurate timing of gaze input and a solution to the "Midas touch" problem, i.e. the accidental triggering of input when looking at an interface. We introduce a novel clock paradigm to study input timing and demonstrate that voluntary convergences are significantly more accurate and precise than common gaze dwelling. Our findings suggest that voluntary convergences are well-suited for applications in which timing of user input is important, thereby complementing existing gaze techniques that focus on speed and spatial precision.
