Cursor Control Trace: Another look into eye-gaze, hand, and eye-hand pointing techniques

摘要

We analyzed cursor control trace with respect to three cursor control methods: eye-gaze, hand, and eye-hand. First, we look into the mechanism that allows users to control cursor positions by hands and/or eyes. Second, we conducted an experiment in which subjects perform a searching, pointing and selection task in three different conditions (eye-only, hand-only, and eye-hand). Third, we further studied the cursor trace and analyzed the moments when users switch between eye-gaze-control and hand-control. Although different from a simpler Fitt's pointing task, our results mostly corroborate previous work. In addition, the cursor traces analysis further shows why eye-hand is more efficient, and how users progress from an inefficient pointing behavior to an optimal one.
