Space weather storms typically have solar, interplanetary, geophysical and societal-effect components that overlap in time, making it hard for students novices to determine cause-and-effect relationships relative timing. To address this issue, we use timelines provide context space of different intensities. First, present a timeline tabular description the great auroral last 500 years as an exa...

We present a visualization system that helps designers conceptualise interactions in a virtual environment (VE). We use eventcondition-action triads (triggersets) for specifying interactions, and provide multiple visualizations: sequence diagrams, floorplans and timelines. We present a two part study: sequencing VE interactions accurately and debugging mistakes. Subjects were divided into two g...

Time is a powerful and common attribute for exploring information, and timelines can be an excellent way to help represent and explore temporal data. Most timelines hit problems when the dataset has a large number of values or attributes, or when the data to be conveyed is multidimensional. We previously introduced Continuum, a tool to support rich temporal visualisations by allowing nested hie...

During our constant interaction with computers, we generate large amounts of personal information. However, it is often hard to find a certain item we are looking for, since our data is spread throughout several places and applications. Nevertheless, a meaningful visualization technique may be the solution to this problem. We present VisMe, an interactive integrated visualization system for per...

Excessive wait times for magnetic resonance imaging (MRI) studies are a major problem in the Canadian healthcare system. To determine how requests for MRI studies are managed, the authors performed a survey of public MRI facilities in Canada. Ninety-six per cent had some method to triage MRI requests. However, only 42% had documented guidelines for prioritization, and none employed quality assu...
