Addressing the need to tailor usability evaluation methods (UEMs) and promote effective reuse of HCI knowledge for computing activities undertaken in divided-attention situations, we present the foundations of a unifying model that can guide evaluation efforts for notification systems. Often implemented as ubiquitous systems or within a small portion of the(More)
Classroom BRIDGE supports activity awareness by facilitating planning and goal revision in collaborative, project-based middle school science. It integrates large-screen and desktop views of project times to support incidental creation of awareness information through routine document transactions, integrated presentation of awareness information as part of(More)
This paper reports on current development of usability heuristics for large screen information exhibits. By basing the creation of such heuristics on real systems, and identifying real problems with those systems, our set is grounded and tailored to the specific application class. This process was done through scenario based design techniques involving(More)
People often need to quickly access or maintain awareness of secondary information while busy with other primary tasks. Information visualizations provide rapid, effective access to information, but are generally designed to be examined by users as the primary focus of their attention. The goal of this research is to discover how to design information(More)
This paper describes a heuristic creation process based on the notion of critical parameters, and a comparison experiment that demonstrates the utility of heuristics created for a specific system class. We focus on two examples of using the newly created heuristics to illustrate the utility of the usability evaluation method, as well as to provide support(More)
One of the challenges in building and evaluating ubiquitous computing systems emanates from the fact that they generally have been built to showcase technological innovation without considering how to foretell whether and how people will eventually accept them in their lives. In this study, participants are introduced to the notion of ubiquitous computing(More)
Reacting to challenges that have been observed in human-computer interaction (HCI) education, as well as the multidisciplinary design, science, and engineering underpinnings, we investigate a pedagogical approach based on case methods. Our study of various case method techniques in an undergraduate HCI class provides insights into challenges that can be(More)
Developments in CS1 pedagogy seek to improve the capabilities of students in their understanding of how to write programs. This involves learning how to solve various types of problems through a systematic approach, a challenging task for most students. " Pair programming " as a pedagogical approach, is one in which students help one another learn how to(More)
