This work reports on the findings of a field study examining the current use practices of large ambient information displays in public settings. Such displays are often assumed to be inherently eye-catching and appealing to people nearby, but our research shows that glancing and attention at large displays is complex and dependent on many factors.

As the trend towards technology-enriched home environments progresses, the need to enable users to create applications to suit their own lives increases. While several recent projects focus on lowering barriers for application creation by using simplified input mechanisms and languages, these projects often approach application creation from a developer's(More)
Global warming, and the climate change it induces, is an urgent global issue. One remedy to this problem, and the focus of this paper, is to <i>motivate</i> sustainable energy usage <i>behaviors</i> by people. One approach is the development of technologies that provide real-time, continuous feedback of energy usage. However, there is one problem - most(More)
Persuasive technology to motivate healthy behavior is a growing area of research within HCI and ubiquitous computing. The emergence of commercial wearable devices for tracking health- and fitness-related activities arguably represents the first widespread adoption of dedicated ubiquitous persuasive technology. The recent ubiquity of commercial systems(More)
Large interactive displays for supporting workgroup collaboration comprise a growing area of ubiquitous computing research and many such systems have been designed and deployed in laboratory studies and research settings. Such displays face difficulties in real-world deployments, as they are often supplemental technologies as opposed to primary tools for(More)
We present a qualitative study of mobile phone ownership, replacement and disposal practices geared towards identifying design opportunities towards sustainable mobile phone interfaces. Our work investigates how people understand the lifespan of their phones, what factors, such as style, service contracts, and functionality, affect how they attribute value(More)
Despite significant progress in sustainable HCI towards theoretical frameworks to guide design, there is a gap between theory and practice, so that the impact of such frameworks is limited. As an initial exploration in bridging the theory-practice gap, we conducted a study using one well-established design framework, the Attachment Framework, to evaluate(More)
The relationship between occupancy of thrombin receptors on platelets and enhanced phosphoinositide hydrolysis was analysed by examination of the dose-response relationship, the effects of thrombin inhibitors and the contribution of secondary effects. Washed human platelets were labelled with [3H]inositol, and agonist-induced accumulation of labelled(More)
Platelets are activated by many different agonists that act synergistically. Since there is a characteristic pattern of responses to each agonist, and since there is a clear distinction between weak and strong agonists, understanding the nature of the synergism and its physiologic significance requires characterization of the pattern of responses to the(More)
