Xbox 720 - IllumiRoom uses the area surrounding a display as surfaces for “peripheral projected illusions”—projected visualizations that enhance traditional viewing and gaming experiences. At first glance, this proof-of-concept augmented-reality system appears straightforward: create an immersive experience by integrating an off-the-shelf projector with a to extend the field of view (FOV) surrounding the display. It takes a few moments to realize that IllumiRoom is extrapolating from images on the screen: The projections are being rendered in real time in response to on-screen content. Delve into the research behind the project, and it turns out the IllumiRoom team not only solved immense technical problems, but also had to cope with creative challenges to blur the lines between the physical and the virtual.
