How should Ubicomp technologies be evaluated? While lab studies are good at sensing aspects of human behavior and revealing usability problems, they are poor at capturing context of use. In-situ studies are good at demonstrating how people appropriate technologies in their intended setting, but are expensive and difficult to conduct. Here, we show how they(More)
Can ubiquitous technologies be designed to nudge people to change their behavior? If so, how? We describe an ambient installation that was intended to help people decide - and to encourage them to reflect - when confronted with a choice. In this particular case, it was whether to take the stairs or the elevator in their place of work. The rationale was to(More)
The Community Collage (CoCollage) is designed to cultivate community in a café, a quintessential "third place", by bringing the richness of online social software into a physical community space. The system shows photos and quotes uploaded to a web site by café patrons and staff on a large computer display in the café, providing a new channel(More)
We describe a study that investigated how a shared interactive tabletop (DiamondTouch) can be designed to provide new opportunities for supporting collaborative decision-making. Small groups of users were required to work together using the table by selecting and placing digital images into a calendar template and justifying their choices to one-to-another.(More)
Mobile technologies are increasingly being promoted as tools to enhance learning. They can be used to augment ongoing activities, such as exploring outdoors, by enabling users to move back and forth between the physical environment and a variety of digital resources and representations. In so doing, they have the potential to facilitate sensemaking(More)
In this paper we discus the complex task of evaluating ambient displays, concentrating on issues within in-situ deployments. We start by describing how these technologies have been evaluated in lab settings, where the focus has been primarily on issues of usability, and argue strongly for the necessity of in-situ evaluation. We then present two case studies(More)
CoCollage is a placed-based community technology that leverages the power of online social networking to facilitate awareness and face-to-face interactions in a third place. We adapted standardized measures of place attachment, social networks and psychological sense of community to provide a framework grounded in the social science literature for studying(More)
Home monitoring represents an appealing alternative for older adults considering out-of-home long term care and an avenue for informal caregivers and health care providers to gain decision-critical information about an older adults’ health and well-being. However, privacy concerns about having 24/7 monitoring, especially video monitoring, in the home(More)
We describe the use of an ambient display called Twitterspace for promoting awareness of events and member activities within our community centers. Content for the display pulls from the social networking platform Twitter. Tweets, which are the recent posts from community members, move across large screens placed in public rooms. Through the concept of(More)
