I'm Tiffany Chao from the Human-Computer Interaction Lab, working with
Prof. Ben Shneiderman and Dr. Catherine Plaisant.

We're conducting a user study to evaluate a graphic user interface. If you
have half an hour to spare, please consider participating in our study.
You'll be paid $10.00 for your time.

Anyone over the age of 18 is welcome to participate. The experiment will be
conducted in Hornbake Library, South Wing. Available testing times can be
found here: http://www.doodle.com/3irhf6f7npxavb4a.
