Exploring the design space of bezelinitiated gestures for mobile interaction

Bezel enables useful gestures supplementary to primary surface gestures for mobile interaction. However, the existing works mainly focus on researcher-designed gestures, which utilized only a subset of the design space. In order to explore the design space, the authors present a modified elicitation study, during which the participants designed bezel-initiated gestures for four sets of tasks. Different from traditional elicitation studies, theirs encourages participants to design new gestures. The authors do not focus on individual tasks or gestures, but perform a detailed analysis of the collected gestures as a whole, and provide findings which could benefit designers of bezel-initiated gestures.
