CTAT: Tilt-and-Tap Across Devices

Motion gestures have been proposed as an interaction paradigm for pairing, and sharing data between, mobile devices. They have also been used for interaction with large screens such as semi-public displays where a mobile phone can be used as a form of remote control in an eyes-free manner. Yet, so far, little attention has been paid to their potential use in cross-device web applications. We therefore decided to develop a framework that would support investigations into the use of a combination of touch and tilt interactions in cross-device scenarios. We first report on a study that motivated the development of the framework and informed its design. We then present the resulting Cross-Tilt-andTap (CTAT) framework for the rapid development of applications that make use of various motion gestures for communication between two or more devices. We conclude by describing an applications developed using
