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)
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)
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)
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)
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)
Multiple-view visualizations are useful for finding patterns in complex data sets, but little research has been done on how they are used. We performed a controlled experiment to study cognitive strategies and context switching by using combination of visualizations and different task types as independent variables, and collecting qualitative and(More)
Synaptic membranes, highly enriched in nicotinic receptor, contain three 43 000 molecular weight (Mr) peripheral proteins (distinctive in their peptide mapping profiles and earlier designated v1, v2, and v 3) as well as the receptor alpha 2 beta gamma delta integral membrane subunits. Of the three proteins, only v1 is copurified with the membrane-bound(More)
Creatine kinase, actin, and nu 1 are three proteins of Mr 43 000 associated with membranes from electric organ highly enriched in nicotinic acetylcholine receptor. High levels of creatine kinase are required to maintain adequate ATP levels, while actin may play a role in maintaining the synaptic cytoskeleton. Previous investigations have prompted the(More)
To streamline detection of calmodulin-binding proteins, blotting techniques for the electrophoretic transfer of proteins onto nitrocellulose filters, followed by overlay with 125I-calmodulin, have been adapted. Autoradiography of the 125I-calmodulin-labeled blots allows the identification and quantitation of proteins that possess affinity for calmodulin.(More)
Data Verse Domain Specific Data Burns research has shown that high-time and high-space (or integrated view visualization) supports performance better than multiple-view visualizations presented either simultaneously or sequentially (Burns, 2000). She argues that the reason for this is that integrated-view visualizations are able to show the data in a(More)
