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)
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)
Instant messaging (IM) in the workplace has proven to be a valuable tool for facilitating informal communication. Its benefits, however, are generally limited to times when users are in front of their computers. Because so much work takes place while people are mobile within their workplace, we sought to extend the benefits of IM beyond people's personal(More)
Research in the field of large-display groupware applications has yet to yield a killer app, a common look and feel for applications, or a set of broadly applicable design principles. It's therefore difficult to understand what constitutes a successful large-display groupware application and what affects their adoption. Although large-display groupware(More)
Large interactive display systems are becoming increasingly pervasive, but most have been studied in isolation, rather than in the context of other technologies in the environment. We present an in-depth field evaluation of large interactive displays within a multi-display work environment used in the NASA Mars Exploration Rover (MER) missions, a complex(More)
