The PIT, or protein interaction theater was designed to use head-tracked stereo to present two users with coupled views of a shared workspace. To improve this system, McKenzie-Maree Slaughter is currently working on connecting the molecular graphics program "spock" to the PIT. Spock, http://quorum.tamu.edu/spock/, is used in the program in cellular and molecular biophysics, so hooking it into our visualization tools will enhance our ability to collaborate with students and faculty in the biophysics program. Work continues on evaluating what makes visualization and virtual environments effective ways to collaborate.
