Hover sensing capability provides richer interactions on mobile devices. For one such exploration, we show a quick double crossing in-air gesture for mobile devices, called AirFlip. In this gesture, users move their thumb into the hover zone from the side, and then move it out of the hover zone. Since this gesture does not conflict with any touch gestures that can be performed on mobile devices, it will serve as another gesture on mobile devices with touchscreens where only a limited input vocabulary is available. We implemented two applications based on AirFlip. In this paper, we show the results of a comparative user study that we conducted to identify the performance of AirFlip. We also discuss the characteristics of AirFlip on the basis of the results.
