Virginia Tech's Center for Human-Computer Interaction presents the project abstracts for the REU 2010 symposium. The REU (Research Experience for Undergraduates) program provides undergraduate students from various universities with the opportunity to spend eight weeks at Virginia Tech, working with our faculty and graduate students on research projects using the state-of-the-art technology and laboratories assembled here. The REU program is sponsored primarily by the National Science Foundation (IIS-0851774, IIS-0552732). Additional support was provided by the NSF (CNS-0540509), and the VT CS Department CSRC.
