Closing-the-Loop in NVisionIP: Integrating Discovery and Search in Security Visualizations
Found in: Visualization for Computer Security, IEEE Workshops on
By Kiran Lakkaraju, Ratna Bearavolu, Adam Slagell, William Yurcik, Stephen North
Issue Date:October 2005
pp. 9
The field of security visualization is in need of a paradigm shift in order to allow visualization tools to be practically used by security engineers. Security engineers must complete two different tasks, that of Discovery of a pattern, and that of Searchi...
 
A maxent-stress model for graph layout
Found in: Visualization Symposium, IEEE Pacific
By Emden R. Gansner,Yifan Hu,Stephen North
Issue Date:March 2012
pp. 73-80
In some applications of graph visualization, input edges have associated target lengths. Dealing with these lengths is a challenge, especially for large graphs. Stress models are often employed in this situation. However, the traditional full stress model ...
 
Multilevel agglomerative edge bundling for visualizing large graphs
Found in: 2011 IEEE Pacific Visualization Symposium (PacificVis)
By Emden R Gansner, Yifan Hu,Stephen North,Carlos Scheidegger
Issue Date:March 2011
pp. 187-194
Graphs are often used to encapsulate relationships between objects. Node-link diagrams, commonly used to visualize graphs, suffer from visual clutter on large graphs. Edge bundling is an effective technique for alleviating clutter and revealing high-level ...
 
Guest Editors' Introduction: Highlights from IEEE Pacific Visualization
Found in: IEEE Computer Graphics and Applications
By Jarke van Wijk, Stephen North, Han-Wei Shen
Issue Date:November 2010
pp. 14-15
This article looks briefly at four articles based on papers from the 2010 IEEE Pacific Visualization Symposium. These articles, which strongly focus on visual design and applications, cover a range of applications in scientific visualization, information v...
 
Topological Fisheye Views for Visualizing Large Graphs
Found in: Information Visualization, IEEE Symposium on
By Emden Gansner, Yehuda Koren, Stephen North
Issue Date:October 2004
pp. 175-182
Graph drawing is a basic visualization tool. For graphs of up to hundreds of nodes and edges, there are many effective techniques available. At greater scale, data density and occlusion problems often negate its effectiveness. Conventional pan-and-zoom, an...
 
Visualization Research with Large Displays
Found in: IEEE Computer Graphics and Applications
By Bin Wei, Claudio Silva, Eleftherios Koutsofios, Shankar Krishnan, Stephen North
Issue Date:July 2000
pp. 50-54
Telecommunication networks and services generate tens of gigabytes of data every day. These data record various characteristics of the networks. Visualizing massive data at full scale and at different levels of abstraction provides an effective means of an...
 
Inferring human mobility patterns from anonymized mobile communication usage
Found in: Proceedings of the 10th International Conference on Advances in Mobile Computing & Multimedia (MoMM '12)
By James R. Rowland, Kwan-Liu Ma, Stephen North, Yuzuru Tanahashi
Issue Date:December 2012
pp. 151-160
Anonymized Call Detail Records (CDRs) contain positional information of large populations and therefore have been extensively analyzed to understand human mobility. Due to the temporally sparse and spatially coarse nature of the data, most of these studies...
     
A comparison of speech and GUI input for navigation in complex visualizations on mobile devices
Found in: Proceedings of the 12th international conference on Human computer interaction with mobile devices and services (MobileHCI '10)
By Eleftherios Koutsofios, Rui Zhang, Stephen North
Issue Date:September 2010
pp. 357-360
Mobile devices are ubiquitously used to access web applications. Multimodal mobile interfaces can offer advantages over less flexible approaches, in both usability and range of features. In this study we consider applying speech input to a web-based networ...
     
LiveRAC: interactive visual exploration of system management time-series data
Found in: Proceeding of the twenty-sixth annual SIGCHI conference on Human factors in computing systems (CHI '08)
By Eleftherios Koutsofios, Peter McLachlan, Stephen North, Tamara Munzner
Issue Date:April 2008
pp. 49-54
We present LiveRAC, a visualization system that supports the analysis of large collections of system management time-series data consisting of hundreds of parameters across thousands of network devices. LiveRAC provides high information density using a reo...
