Edge Compression Techniques for Visualization of Dense Directed Graphs
Found in: IEEE Transactions on Visualization and Computer Graphics
By Tim Dwyer,Nathalie Henry Riche,Kim Marriott,Christopher Mears
Issue Date:December 2013
pp. 2596-2605
We explore the effectiveness of visualizing dense directed graphs by replacing individual edges with edges connected to 'modules'-or groups of nodes-such that the new edges imply aggregate connectivity. We only consider techniques that offer a lossless com...
 
PivotPaths: Strolling through Faceted Information Spaces
Found in: IEEE Transactions on Visualization and Computer Graphics
By M. Dork,Nathalie Henry Riche,G. Ramos,S. Dumais
Issue Date:December 2012
pp. 2709-2718
We present PivotPaths, an interactive visualization for exploring faceted information resources. During both work and leisure, we increasingly interact with information spaces that contain multiple facets and relations, such as authors, keywords, and citat...
 
Visual Thinking In Action: Visualizations As Used On Whiteboards
Found in: IEEE Transactions on Visualization and Computer Graphics
By Jagoda Walny,Sheelagh Carpendale,Nathalie Henry Riche,Gina Venolia,Philip Fawcett
Issue Date:December 2011
pp. 2508-2517
While it is still most common for information visualization researchers to develop new visualizations from a data- or taskdriven perspective, there is growing interest in understanding the types of visualizations people create by themselves for personal us...
 
Untangling Euler Diagrams
Found in: IEEE Transactions on Visualization and Computer Graphics
By Nathalie Henry Riche, Tim Dwyer
Issue Date:November 2010
pp. 1090-1099
In many common data analysis scenarios the data elements are logically grouped into sets. Venn and Euler style diagrams are a common visual representation of such set membership where the data elements are represented by labels or glyphs and sets are indic...
 
Mélange: Space Folding for Visual Exploration
Found in: IEEE Transactions on Visualization and Computer Graphics
By Niklas Elmqvist, Yann Riche, Nathalie Henry-Riche, Jean-Daniel Fekete
Issue Date:May 2010
pp. 468-483
Navigating in large geometric spaces—such as maps, social networks, or long documents—typically requires a sequence of pan and zoom actions. However, this strategy is often ineffective and cumbersome, especially when trying to study and compare several dis...
 
A Deeper Understanding of Sequence in Narrative Visualization
Found in: IEEE Transactions on Visualization and Computer Graphics
By Jessica Hullman,Steven Drucker,Nathalie Henry Riche,Bongshin Lee,Danyel Fisher,Eytan Adar
Issue Date:December 2013
pp. 2406-2415
Conveying a narrative with visualizations often requires choosing an order in which to present visualizations. While evidence exists that narrative sequencing in traditional stories can affect comprehension and memory, little is known about how sequencing ...
 
Understanding Pen and Touch Interaction for Data Exploration on Interactive Whiteboards
Found in: IEEE Transactions on Visualization and Computer Graphics
By Jagoda Walny,Bongshin Lee,Paul Johns,Nathalie Henry Riche,Sheelagh Carpendale
Issue Date:December 2012
pp. 2779-2788
Current interfaces for common information visualizations such as bar graphs, line graphs, and scatterplots usually make use of the WIMP (Windows, Icons, Menus and a Pointer) interface paradigm with its frequently discussed problems of multiple levels of in...
 
Beyond Mouse and Keyboard: Expanding Design Considerations for Information Visualization Interactions
Found in: IEEE Transactions on Visualization and Computer Graphics
By Bongshin Lee,Petra Isenberg,Nathalie Henry Riche,Sheelagh Carpendale
Issue Date:December 2012
pp. 2689-2698
The importance of interaction to Information Visualization (InfoVis) and, in particular, of the interplay between interactivity and cognition is widely recognized [12,15,32,55,70]. This interplay, combined with the demands from increasingly large and compl...
 
SparkClouds: Visualizing Trends in Tag Clouds
Found in: IEEE Transactions on Visualization and Computer Graphics
By Bongshin Lee, Nathalie Henry Riche, Amy K. Karlson, Sheelash Carpendale
Issue Date:November 2010
pp. 1182-1189
Tag clouds have proliferated over the web over the last decade. They provide a visual summary of a collection of texts by visually depicting the tag frequency by font size. In use, tag clouds can evolve as the associated data source changes over time. Inte...

Hard-to-use interfaces considered beneficial (some of the time)
Found in: Proceedings of the 28th of the international conference extended abstracts on Human factors in computing systems (CHI EA '10)
By Anastasia Bezerianos, Nathalie Henry Riche, Petra Isenberg, Yann Riche
Issue Date:April 2010
pp. 2705-2714
Researchers in HCI share a common understanding that 'easy-to-use', 'easy-to-learn' and 'intuitive' interfaces are beneficial to users. Designing such interfaces raises challenges and often requires multiple iterations. While we are generally prompt to dis...
     
Weighted graph comparison techniques for brain connectivity analysis
Found in: Proceedings of the SIGCHI Conference on Human Factors in Computing Systems (CHI '13)
By Basak Alper, Benjamin Bach, Jean-Daniel Fekete, Nathalie Henry Riche, Tobias Isenberg
Issue Date:April 2013
pp. 483-492
The analysis of brain connectivity is a vast field in neuroscience with a frequent use of visual representations and an increasing need for visual analysis tools. Based on an in-depth literature review and interviews with neuroscientists, we explore high-l...
