New audiovisual experiences involve consuming several contents displayed through multiple internet-connected devices. The TV is still the central hub of the living room, but it is often used simultaneously with other screens. Consequently, the user has the chance to consume all different contents at once across multiple devices. However, no existing adaptation models are available to dynamically adapt such a multitude of contents in multi-device contexts. To address this gap, this paper proposes a novel multi-device adaptation methodology to build adaptive User Interfaces for multi-screen hybrid broadcastbroadband TV experiences. The methodology is extensible to any kind of content, device and user, and is applicable to different contexts considering technological evolution and other fields of application. The proposed methodology is the outcome of extensive research that arose from a previous multi-device media service deployment with broadcasters.
The quest to transform the television viewing experience into a digital media service is happening thanks to the addition of companion screens to the TV. Multi-device experiences become more intuitive and easier to use federating cooperative devices. They also bring new creative opportunities to schedule and distribute interactive content synchronised with the TV programme through any connected screen. The rise of HTML5 to develop responsive applications across multiple devices adds a significant amount of improvement enabling universal delivery. A key challenge to harness the power of navigation engaged with the story on the TV is the responsive design of a unique application spanning all the available screens. This paper presents user tests in order to explore the relevant parameters to create responsive User Interfaces for Web-based multi-device applications driven by media content.
