Mnemonical Body Shortcuts for Interacting with Mobile Devices, in: Sales

Abstract. Mobile devices ’ user interfaces have some similarities with the traditional interfaces offered by desktop computers, which are highly problematic when used in mobile contexts. Gesture recognition in mobile interaction appears as an important area to provide suitable on-the-move usability. We present a body space based approach to improve mobile device interaction and on the move performance. The human body is presented as a rich repository of meaningful relations which are always available to interact with. Body-based gestures allow the user to naturally interact with mobile devices with no movement limitations. Preliminary studies using RFID technology were performed, validating the mnemonical body shortcuts concept as a new mobile interaction mechanism. Finally, inertial sensing prototypes were developed and evaluated, proving to be suitable for mobile interaction and efficient, accomplishing a good recognition rate
