Point-and-click interface modalities are a pervasive method of interacting with graphical user interfaces. Users of mouse-replacement interfaces use alternative input devices to replace the mouse for pointing and clicking. We present a comparison of click actuation modalities with users of the Camera Mouse, a motion-tracking mouse interface. We compare dwell-time click generation against detecting a single intentional muscle contraction with an attached sensor (ClickerAID). A preliminary evaluation was conducted as well as an in-depth case study with a participant with the neuromuscular disease Friedreich’s Ataxia. The case study shows modest temporal differences among the test conditions in movement time and throughput, though the participant subjectively favored the ClickerAID interface.
