By now, almost everyone has seen the cool You Tube video of the Japanese students fake skydiving using a projector and Google Earth. However, all the posts and comments focus on the skydiving part and how realistic, non-realistic, or just plain awesome it is. When I watched it my first thought was, “that is a really cool way to build a cheap, portable virtual environment.” The closest approximation I could find to what they did are electronic art canvases which cost about $3,000. They are used at the really cool Collaborative Advanced Navigation Virtual Art Studio at the Krannert Art Museum/University of Illinois, Champaign. To do truly immersive research and projects, virtual environments such as the EON Icube cost upwards of $50,000 to over $1 million dollars. Which brings me to the other thought I had while watching the Google Skydiving video, “There is no way anyone would let you do that in a commercial virtual environment, especially if there is a chance someone would get motion sick or worse bring down a sensor or mirror.” But I can add this to my list of things I would do if I had my own CAVE, along with play massive multi-player online video games and make my own music video.
