Towards a Multi-screen Application Model for the Web

The ever-growing ubiquity and power of mobile devices and the trend of televisions becoming more than just dumb displays for moving images are two sides of the same coin. Both types of devices have outgrown their original purpose and are now used for tasks that previously required a PC or laptop. At the same time, users often own and use multiple devices in parallel, e.g. when watching TV or while working. Traditional application models are however focused on single devices and screens, although Apps for the "second screen" have been getting a lot of interest recently. In this paper we propose a new approach for designing and developing multi-screen applications using standard web technologies and outline how to enable traditional web applications to become multi-screen-ready.
