The mission of the Virtual Human Interaction Lab at Stanford University is to understand the dynamics and implications of interactions among people in immersive virtual reality simulations (VR).

This paper by Sepandar Kamvar and Taher Haveliwala proves analytically the second eigenvalue of the Google Matrix, which has implications for the PageRank algorithm.
