Large multi-touch displays are expanding the possibilities of multiple-coordinated views by allowing multiple people to interact with data in concert or independently. We present Lark, a system that facilitates the coordination of interactions with information visualizations on shared digital workspaces. We focus on supporting this coordination according to(More)
BACKGROUND To date only two controlled studies have been published on the effects of domiciliary oxygen treatment on survival in patients with chronic obstructive pulmonary disease (COPD) with advanced respiratory failure. The survival in such patients despite oxygen treatment remains poor. The prescription of long term oxygen therapy (LTOT) in less severe(More)
Tabletop displays with touch-based input provide many powerful affordances for directly manipulating and collaborating around information visualizations. However, these devices also introduce several challenges for interaction designers, including discrepancies among the resolutions of the visualization, the tabletop's display, and its sensing technologies;(More)
Nine healthy subjects (age 31 +/- 4 yr) exercised with and without expiratory-flow limitation (maximal flow approximately 1 l/s). We monitored flow, end-tidal PCO2, esophageal (Pes) and gastric pressures, changes in end-expiratory lung volume, and perception (sensation) of difficulty in breathing. Subjects cycled at increasing intensity (+25 W/30 s) until(More)
We present a case study of an interactive, multiple heterogeneous-display, multi-touch visualization for informal science education. Our visual simulation application, called WALDEN, has been developed using a Microsoft Surface and a large data wall. Multiple displays offer users the opportunity to interact with large visual datasets and observe complex(More)
—We consider the problem of developing colour sequences that offer the best dynamic range when used for pseudo-colouring. We began with nine colour sequences currently suggested for visualization and informally compared them to discover which was subjectively seen to have the most pleasing visual aesthetic. This comparison indicated that different colour(More)
Home treatment for chronic respiratory insufficiency: the situation in Europe in 1992. ABSTRACT: The search for improved quality of life and a reduction in health care costs is leading to the development of home treatment. The organization of home treatment for chronic respiratory patients in 13 European countries was evaluated at the end of 1992 by means(More)
