Recently there has been a transformative shift towards engaging with mobile devices while watching television. Content creators, therefore, wish to create applications to support these behaviours to provide more engaging multi-device TV. Currently, their designs do not reflect the subtle variations in viewer attention, our physiological capabilities, or the additional mental effort such scenarios imply. We investigate this in two primary ways: by further understanding the current issues faced by users when dual-screening, and by designing a series of technological interventions for managing cross-device attention. First, we conduct two studies to better understand the user experience of second screening. Through a large-scale online questionnaire and a series of interviews we document the problems faced by users when second screening and how they compensate and mitigate for missing content when engaging with mobile devices. We then conduct an investigation to explore the effect of dual-screen visual complexity in terms of objective and subjective experience of participants when exposed to content of varying complexity across two screens. For our technological interventions, we first investigate how visual complexity on a mobile device may be varied to account for the perceived complexity of TV material by loading textual material at varying levels of complexity. We explore the tradeoff of user autonomy and content creator control by contrasting the effects of users adjusting the complexity themselves, and automatic adjustment around heuristics. Then, we consider how different audio-visual stimuli may be used to direct a user’s attention between screens at key moments. Finally, we explore how we can support users to reduce the switching costs and cognitive effort associated with engaging with cross-device media mirroring unattended visual information in the experience on an attended screen. Throughout the thesis we show that many of our interventions are a beneficial state of the art and form a series of guidelines for each. The thesis concludes by offering an outline of our contributions and a framework for others to extend our work.
