Comparison between augmented and virtual reality

Tang, A., Biocca, F., and Lim, L. (2004). Comparing Differences in Presence during Social Interaction in Augmented Reality versus Virtual Reality Environments: An Exploratory Study In Proceedings of PRESENCE 2004, 7th Annual International Workshop on Presence, October 13–15, 2004, Valencia, Spain.This paper offers an interesting conclusion with regard to the differences between augmented reality and virtual reality: "the absence of representations of the user’s body in VR environment may lessen sense of spatial presence comparing with AR environment".

I like what this lab does, namely experiments about cognition in AR.
