Ergonomics research on eye–hand control dual channel interaction

Abstract

Eye-control interfaces are human–computer interfaces in which interaction is mediated by the user’s gaze. Using dwell time for target selection may be hindered by the “Midas Touch” problem, which posits that intentional selection and perceptual processes cannot be separated. To solve this problem, we investigated the influence of different dwell times on task performance. Results suggest that the optimal dwell time to trigger a click in eye-control movement plus eye-control click and hand-control movement plus eye-control click are 700 and 200 ms, respectively. In addition, the eye-control movement plus eye-control click mode has a lower completion rate than the hand-control movement plus eye-control click mode.
