The emergence of widespread pervasive sensing, personal recording technologies, and systems for the quantified self are creating an environment in which one can capture fine-grained activity traces. Such traces have wide applicability in domains such as human memory augmentation, behavior change, and healthcare. However, obtaining these traces for research(More)
As the cost of display hardware falls so the number of public display networks being deployed is increasing rapidly. While these networks have traditionally taken the form of digital signage used for advertising and information there is increasing interest in the vision of "open display networks" [8]. A key component of any open display network is an(More)
Traditional digital signage analytics are based on a display-centric view of the world, reporting data on the content shown augmented with frequency of views and possibly classification of the audience demographics. What these systems are unable to provide, are insights into viewers' overall experience of content. This is problematic if we want to(More)
A recent trend in mobile computing is the increasing use of worn devices for data capture. Wearable lifelogging cameras such as the SenseCam and Narrative Clip reflect this trend, allowing mobile users to continuously capture images for later review. Image streams provided by these mobile devices can be used in a range of applications, but are commonly used(More)
Scheduling content onto pervasive displays is a complex problem. Researchers have identified an array of potential requirements that can influence scheduling decisions, but the relative importance of these different requirements varies across deployments, with context, and over time. In this paper we describe the design and implementation of a lottery-based(More)
While traditional displays networks are typically closed systems, researchers are now beginning to explore the notion of open display networks in which content can be obtained from a wide range of sources. Open display networks have very different properties to closed networks as they need to deal with multiple management domains and conflicting content and(More)
Users are increasingly accessing content through a complex device eco-system involving both public and private screens. Traditional research into display eco-systems has focused on developing new multi-screen applications and on techniques for understanding how interactions and activities such as shopping flow across screens and devices. There has been(More)
Digital displays are a ubiquitous feature of our public spaces - both ever present, and "always on". In this paper we use a combination of literature survey, experimental work, and stakeholder interviews to consider if maximising the amount of time such displays are powered on is truly advantageous. We challenge existing practice by considering arguments(More)
Cued-recall graphical passwords have a lot of potential for secure user authentication, particularly if combined with saliency masks to prevent users from selecting weak passwords. Saliency masks were shown to significantly improve password security by excluding those areas of the image that are most likely to lead to hotspots. In this paper we investigate(More)
