Visualize -- or Visual Lies?

Stephen Hughes, an independent researcher currently living in Cedar Falls, will deliver a CS seminar on Wednesday, December 10, at 3:30 PM in 322 ITTC.


Computer visualizations can harness the power and flexibility of the human perceptual system to quickly identify critical features in a large set of data. Research in visual information systems seeks to identify design guidelines for visualizations that allow us to efficiently and effectively explore ideas.

However, every technology has its dark side. A picture may be worth a thousand words, but what if it is used to elaborately describe a lie? This discussion will explore what makes visual displays effective and what happens when they effectively deceive the viewer.

Is seeing really believing?

Stephen Hughes took his a Ph.D. in Information Science from the University of Pittsburgh in 2005, with a dissertation on interaction with 3D visualizations. Most recently, Stephen was an assistant professor of computer science at Roanoke College in Virginia.

Diversity Matters


Mark Fienup

As a discipline, computer science is relatively young and characterized by rapid technological advances. This dynamism is reflected in the interests of Mark Fienup, associate professor of computer science: Parallel computing, routing and computer networks, and computer science education are all greatly affected by the changing nature of computer science....
