Existing mobile phones use the front screen for gesture interactions, but they often suffer from usability problems such as content occlusion and spurious triggering caused by fat finger errors. Recent advances in new sensor technologies have made it possible for modern mobile phones to recognize gesture inputs on the rear screen. Although inputs from the backside of a mobile phone have demonstrated their usefulness for simple interaction tasks such as target acquisition, little is known regarding the best practices in gesture design for complex concurrent tasks on dual-screen mobile devices. Therefore, we conducted a three-stage study to explore user-defined multi-finger gestures for concurrent game tasks on a dual-screen mobile device. Experimental results indicate the existence of a consensus between participants regarding gesture choices for specified game tasks. Based on this consensus, we developed a gesture taxonomy and generated a set of user-defined gestures for dual-screen mobile devices. A subsequent benchmark test validated the popularity of the user-defined gestures with both ordinary and professional game players.
