A new schematic framework for navigation is presented which is relevant to physical, abstract and social environments. Navigation is de"ned as the creation and interpretation of an internal (mental) model, and its component activities are browsing, modelling, interpretation and the formulation of browsing strategy. The design of externalizations and(More)
Primary sclerosing cholangitis (PSC) is an inflammatory disease of unknown etiology. It affects the biliary system and is characterized by fibrosis and progressive obliteration of extrahepatic and intrahepatic bile ducts. Its frequent coexistence with antibody-mediated diseases, certain human leukocyte antigens, and altered lymphocyte mechanisms suggests a(More)
The Attribute Explorer is a visualization tool in which the graphical and interactive presentation of data supports the human acquisition of insight into that data. The underlying concept employed is that of interactive linked histograms. The advantage of the Attribute Explorer derives from its ability to support both qualitative exploration and(More)

“The Attribute Explorer” video demonstrates a graphical interactive tool for visualizing the relationships within multi-attribute data sets. Rather than using 2or 3dimensional multiple views of the data, each attribute is mapped to a single dimensional representation (interactive histogram). Sections of an attribute’s histogram can be selected by a variety(More)
This paper illustrates the benejits, for a wide range of design activities, of Interactive Visualization Artifacts. INTRODUCTION In an extremely wide range of design tasks, of which electronic product design is an example, the designer is concerned with the influence of the parameters whose values can be chosen upon the performances which are of direct(More)
Rapid Serial Visual Presentation, or RSVP, is the electronic equivalent of riffling a book in order to assess its content. RSVP allows space to be traded for time and has tremendous potential to support electronic information browsing and search particularly on small displays. However, before this potential can be realised, it is necessary to investigate(More)
OBJECTIVE Burn wound depth is a significant determinant of patient treatment and morbidity. While superficial partial-thickness burns generally heal by re-epithelialization with minimal scarring, deeper wounds can form hypertrophic or contracted scars, often requiring surgical excision and grafting to prevent a suboptimal result. In addition, without timely(More)
