Supporting cross-device interactions with gestures between personal and public devices

Seamless interaction across personal and public devices is still problematic. Gestural interaction can be a useful support for this purpose, but how to exploit it in cross-device frameworks is still unclear. We present an elicitation study aiming to contribute in identifying the most intuitive single or combined gestures that people can perform to interact with cross-device applications. This study led us to the definition of a possible gesture vocabulary for the typical interactive tasks in such applications. We then applied the resulting preferred gestures in an example cross-device Web application exploiting it. This application has finally been tested in order to evaluate the gestures' actual usability in cross-device interactions.
