hive-schematicProfessor Eric Hodgson explores some of the psychological impacts of virtual reality when it comes to spatial perception & memory, and effects like change blindness. He also talks about how to walk in infinite VR spaces within limited physical spaces with a technique called redirected walking. Finally, he talks about insights from IEEE VR community on this consumer VR revolution, compares the split between the old VR community to the new VR community, 3D user interfaces, data visualizations, and some examples for how corporations and the military are using VR.

EricHodgson_2008Eric Hodgson is the director of the Smale Visualization Center & also works with the Armstrong Institute for Interactive Media Studies at the Miami University of Ohio. He runs the HIVE (huge immersive virtual environment), which is a gym-sized VR Lab. For more information on Eric, here’s some of his VR research publications.
