Abstract

With the advancement of markerless motion capture technology in recent years, gesture-based interactive technique has come into people’s daily life. In this paper, we conducted a two-stage study on the design of bare-hand gestures in Virtual Reality environment. In the first study, end users were asked to invent barehand gestures for the manipulation of virtual objects freely by themselves. Based on the experimental results, we established baseline criteria to distinguish different types of bare-hand gestures and then derived a user-defined gesture set from the collected data. In the second study, the user-defined gestures were validated in terms of good match, memorability, learnability, and comfort. Participants showed positive attitudes toward the user-defined gesture set. Finally, we report some design guidelines for gesture design and vision-based interface design.
