Checklist usage can increase performance in complex, high-risk domains. While paper checklists are valuable, they are static, slow to access, and show both too much and too little information. We introduce <i>Dynamic Procedure Aids</i> to address four key problems in checklist usage: ready access to aids, rapid assimilation of content, professional(More)
To understand how and why individuals make use of emerging information assimilation services on the Web as part of their daily routine, we combined video recordings of online activity with targeted interviews of eleven experienced web users. From these observations, we describe their choice of systems, the goals they are trying to achieve, their information(More)
In an effort to reduce medical errors, doctors are beginning to embrace cognitive aids, such as paper-based checklists. We describe the early stage design process of an interactive cognitive aid for crisis care teams. This process included collaboration with anesthesia professors in the school of medicine and observation of medical students practicing in(More)
Complex, perilous domains like surgery and aviation require accurate responses under extreme time constraints. Checklists improve important outcomes in these domains. However, current designs are based largely on intuition; there is little theory or empirical work about designing effective procedure aids. Furthermore, discretionary checklist use is(More)
iii for the benefit of all sentient beings iv ABSTRACT Designing user-interfaces so that first-time or infrequent users can accomplish their goals by exploration has been an enduring challenge in Human-Computer Interaction. Iterative user-testing is an effective but costly method to develop user-interfaces that support use through exploration. A(More)
Emergency medical teams collaborate to solve problems and take care of patients under time pressure and high cognitive load, in noisy and complex environments. This paper presents preliminary work in the design and evaluation of head-mounted and multi-surface displays in supporting teams with interactive checklists and more generally dynamic cognitive aids.
7 DISCUSSION The Revert Graph visualization helps identify important social patterns in Wikipedia such as groups with differing viewpoints, mediation, vandal fighting, and user conflicts. The above scenarios demonstrate the effectiveness of the revert-based conflict model, which is based on simple revert relationships between users. These results show how(More)
