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)
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)
This commentary addresses the recently exploited presentation technique called Rapid Serial Visual Presentation, or RSVP, and identifies a number of applications. It describes a number of different RSVP modes, discusses potentially attractive features and reports the results of experimental investigations. Some of the many issues requiring further research(More)
The effects of System Response Time, SRT, on interactive graphical problem solving were investigated for fixed SRT's of 0.16, 0.72 and 1.49 seconds. The object was to demonstrate the importance or otherwise of even small SRT values for interactive graphical problem solving of a type which often occurs in Computer Aided Design. A SRT of 1.49 sec was found to(More)
Rhinophyma is a disfiguring soft-tissue hypertrophy of the nose. It is an uncommon disease that primarily affects Caucasian men in the fifth to seventh decades of life. Nine cases from the authors' series and a comparison of results following various treatment modalities are presented. Eight of the patients were Caucasian and one was African American.(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)
