Tools for collecting users' touch and free-hand gestures on mobile devices in experimental settings

Gesture interaction is now available on a variety of devices that expose touch and/or free-hand gesture interfaces. However, users' capacity to interact efficiently with computing systems using gestures is still to be understood. To this end, the community needs appropriate software tools to record users' gesture input in both experimental and live settings. In this work, we present three software tools that capture and record users' touch and free-hand gesture input on mobile devices. These tools make together a general and unique system that can collect precise data about users' free-hand and touch gestures. The variety of gesture data and gesture measurements reported by our tools will enable practitioners and researchers to form a thorough understanding about their users' performance during gesture interaction with mobile devices. Our tools are free to download and use to collect users' gesture performance on mobile devices in various experimental settings.
