Multi-touch Parallel Coordinates for Interactive InfoVis (video and Info) via Dr. Robert Kosara

Dr. Robert Kosara's area of research is information and data visualization. He is an assistant professor in the Department of Computer Science, College of Computing and Informatics, at the University of North Carolina at Charlotte, and also a member of the Charlotte Visualization Center.   He's fascinated with parallel sets/categorical data visualization.

Dr. Kosara is known for his deep thoughts about information visualization, as well as persuading others that they should think deep thoughts about the subject, too! His latest work is an example of interesting multi-touch interaction with representation of parallel coordinates using multi-touch trackpads commonly found on laptops, including the Macbook Pro.

"This is the companion video for a paper we submitted recently. It describes a technique for interacting with parallel coordinates using the multi-touch trackpad found on laptops like Apple's MacBook Pro. 

Below is the abstract from that paper:
Interaction in visualization is often complicated and tedious. Brushing data in a visualization such as Parallel Coordinates allows the user to select data points according to certain criteria. Modifying a brush or combining it with another one usually requires a lot of additional effort and mode switches.
We propose the use of multi-touch interaction to provide fast and convenient interaction with Parallel Coordinates. By using a multi-touch trackpad rather than the screen directly, the users hands do not obscure the visualization during interaction. Using one, two, three, or four fingers, the user can easily and quickly perform complex selections. Being able to change the selections rapidly, the user can explore the data set more easily and effectively, and can focus on the data rather than the interaction."
