Abstract:
In this paper we present the results from an experiment designed to characterize the Leap Motion movement
in 2D pointing tasks and compare it to a mouse and touchpad. We used the ISO 9241-9 multi-directional
tapping test for comparing the devices, and we analyse the results using standard throughput and error rate
measures as well as additional accuracy measures such as target re-entry, task axis crossing, movement
direction change, orthogonal direction change, movement variability, movement offset, and movement
error. We also present the results from the ISO 9241-9 assessment of comfort questionnaire, and our
observations from the participant’s postures when using the Leap Motion device. Results indicate that the
Leap Motion performs poorly in these tasks when compared to a mouse or touchpad.
