Abstract. We present TimeTilt, a sensor-based technique that allows multiple windows switching on mobile devices, and which overcomes the limitations of mobile devices, i.e. their impoverished input bandwidth (often no keyboard, a small tactile screen and the drawbacks of one-handed interaction). TimeTilt, which is based on a lenticular metaphor, aims at both reducing the activation time when switching between views, and supporting a natural mapping between the gestures and the navigation. We draw a brief classification of sensor-based gestures that could be used in mobile conditions, and we present an experiment.
