GazeShutter: Designing Dwell-free Gaze Gesture Interactions

We propose GazeShutter, a gaze-only input method, which allows users to select targets by performing gaze gesture instead of dwelling. Users select the target on screen by looking target on-screen and target off-screen back and forth. Our method is considered more efficient than conventional dwell- time selection method. The interface of GazeShutter is designed to preserve the contents on screen and utilize Halo system to visualize button off-screen. We conduct the first study to recognize that distance has a significant impact on performing time, though direction doesn’t. Based on the design impli- cations from the observations, we implemented GazeShutter in practice to demonstrate the benefits of our method.
