Toward universal mobile interaction for shared displays

Abstract

Researchers have noted conflicting trends in collaboration technologies between delivering more information on larger displays and exploiting mobility on smaller devices. Large, shared displays provide greater choice in the presentation of information, but mobile devices offer greater flexibility in the access of information. We describe a platform that leverages the best of both worlds by allowing multiple users to access and interact with a large, shared display using their own personal mobile devices, such as a cell phone, laptop, or wireless PDA. We highlight three applications built on top of the platform that demonstrate its generality and utility in a variety of group settings: namely, web browsing, polling, and entertainment.
