4. Technical Presentation

Jamie Ruiz	Title : DoubleFlip: A Motion Gesture Delimiter for Mobile Interaction Abstract: In order to use motion gestures with mobile devices it is imperative that the device be able to distinguish between motion intended for mobile interaction and everyday mo-tion. In this talk I will present DoubleFlip, a unique motion gesture designed to act as an input delimiter for mobile motion gestures (i.e., signaling to the system that the fol-lowing motion should be considered as a gesture). The DoubleFlip gesture can also be used as a shortcut for triggering a designated action (e.g., launching an application). I will present the qualitative user study that influenced the design requirements for DoubleFlip and describe the design and implementation of the gesture. We collected a large dataset collected from over 90 mobile phone users and determined that the DoubleFlip gesture is extremely resistant to false positive conditions (less than 0.001%) and also achieves a high recognition rate (99%). Since DoubleFlip is easy to perform and less likely to be accidentally invoked, it provides an always-active input event for mobile interaction.
