Nintendo shows off video footage software for Wii U.
At the end of Nintendo's E3 press briefing today, Nintendo head Satoru Iwata revealed a piece of software called Wii U Panorama View that makes the Wii U controller into a virtual reality headset, sort of. Nintendo filmed video footage of real world locations, and stitched it together so Wii U owners can move the screen controller around to watch from whatever angle they desire. It's a way of looking at video footage as if you're in the video while it's playing, basically, similar to Google Maps but with video instead of stills.
The demonstration didn't show any interactive elements beyond moving the controller and selecting different camera angles, so it seems likely that Panorama View will be included with the Wii U hardware or downloadable for the system, rather than available as a boxed product.
