Sony / Holodeck
Using a variety of visual tricks, including projection mapping, props, and motion-tracking, Sony have managed to bring to life a sort of crazy virtual "holodeck" experience.
Using the Playstation Move, the production team shot a handful of scenes depicting an ordinary man going from his couch to flying above skyscrapers as a robot and fighting sea monsters. Incredibly, all three clips were shot in real-time, with zero edits or post-production. Everything you see was an optical effect seen through the lens of the camera.
The scenes were created by projecting images onto various 3-dimensional surfaces, and then syncronized a variety of real-world props, booby traps, and triggers in the enviroment to move along with the scene changes. As you saw in the clips, live actors also helped move around various props and contrivances to help with the immersion. They shot the entire thing with a Steadicam, with several of PlayStation Move controllers strapped to it, as well as EyeToy cameras around the room in order automatically track motion and adjust the scene accordingly.
