In this study we investigate the Leap Motion as a gesture-based input device for games in VR. A user study was conducted where five participants played a short game of balancing a board with a rolling ball to collect a number of items, using both the Leap Motion and the joystick of a regular VR controller. We investigate which input modality is preferable, measuring completion time and error rates, as well as qualitative data through observation and interviews. Participants reported physical fatigue and found the lack of vision of their hand to be a noticeable problem when using the Leap Motion compared to the VR controller. However, in terms of time participants completed the game faster with the Leap Motion and results indicate that it was perceived as more intuitive and easier to use than VR controllers. Our study found that Leap Motion was well suited to the type of short game the users participated in, and could be further improved by redesigning the physical surroundings of the user.
