The scalability of information visualizations has typically been limited by the number of available display pixels. As displays become larger, the scalability limit may shift away from the number of pixels and toward human perceptual abilities. This work explores the effect of using large, high resolution displays to scale up information visualizations(More)
Tiling multiple monitors to increase the amount of screen space has become an area of great interest to researchers. While previous research has shown user performance benefits when tiling multiple monitors, little research has analyzed whether much larger high-resolution displays result in better user performance. We compared user performance time,(More)
Larger, higher resolution displays can be used to increase the scalability of information visualizations. But just how much can scalability increase using larger displays before hitting human perceptual or cognitive limits? Are the same visualization techniques that are good on a single monitor also the techniques that are best when they are scaled up using(More)
As display technology continues to improve, there will be an increasing diversity in the available display form factors and scales. Empirical evaluation of how display attributes affect user perceptions and performance can help designers understand the strengths and weaknesses of different display forms, provide guidance for effectively designing multiple(More)
Larger, higher-resolution displays are becoming accessible to a greater number of users as display technologies decrease in cost and software for the displays improves. The additional pixels are especially useful for information visualization where scalability has typically been limited by the number of pixels available on a display. But how will(More)
Large, dynamic, and ad-hoc organizations must frequently initiate data integration and sharing efforts with insufficient awareness of how organizational data sources are related. Decision makers need to reason about data model interactions much as they do about data instance interactions in OLAP: at multiple levels of granularity. We demonstrate an(More)
Designers of information visualization systems have the choice to present information in a single integrated view or in multiple views. In practice, there is a continuum between the two strategies and designers must decide how much of each strategy to apply. Although high-level design guidelines (heuristics) are available, there are few low-level perceptual(More)
Many data sharing communities create data standards (" hub " schemata) to speed information integration by increasing reuse of both data definitions and mappings. Unfortunately, creation of these standards and the mappings to the enterprise's implemented systems is both time consuming and expensive. This paper presents Unity, a novel tool for speeding the(More)
Many Service Oriented Architecture (SOA) approaches in use today presume the consistent availability of reliable networks and limitless resources. For some Department of Defense (DoD) and other Government users, operating at the tactical edge, who may be disadvantaged in terms of network and resource availability, the current methods of development may not(More)
Context: Critical software systems developed for the government continue to be of lower quality than expected, despite extensive literature describing best practices in software engineering. Goal: We wanted to better understand the extent of certain issues in the field and the relationship to software quality. Method: We surveyed fifty software development(More)
