Tromso students put together the best interactive display wall we've seen yet (video)
Take everything you thought you knew about multitouch and throw it out. Okay, keep the Minority Report stuff, but throw everything else out. What we're looking at here is a 22 megapixel display, stitched together from the output of no less than 28 projectors (7,168 x 3,072 total resolution), which just happens to respond to touch-like input in a fashion even Tom Cruise would find fascinating. You don't have to actually touch the wall, floor-mounted cameras pick up your gestures in 2D space and a 30-node computer setup crunches all the computational and visual data to deliver some buttery smooth user interaction. For demo purposes, the makers of this system grabbed a 13.3 gigapixel image of Tromso and took it for a hand-controlled spin. See the mesmerizing show on video after the break.
MIT gestural computing makes multitouch look old hat
Ah, the MIT Media Lab, home to Big Bird's illegitimate progeny, augmented reality projects aplenty, and now three-dimensional gestural computing. The new bi-directional display being demoed by the Cambridge-based boffins performs both multitouch functions that we're familiar with and hand movement recognition in the space in front of the screen -- which we're also familiar with, but mostly from the movies. The gestural motion tracking is done via embedded optical sensors behind the display, which are allowed to see what you're doing by the LCD alternating rapidly (invisible to the human eye, but probably not to human pedantry) between what it's displaying to the viewer and a pattern for the camera array. This differs from projects like Natal, which have the camera offset from the display and therefore cannot work at short distances, but if you want even more detail, you'll find it in the informative video after the break.

Microsoft Surface - surface and gesture based computing lands
Over the years we've seen plenty of surface and gestural interface computing systems and prototypes, but nothing mass-market -- nothing consumable, if you will. Microsoft aims to change all that with Surface, its first foray into surface / gestural interfaces; arriving in the form of a 30-inch table-like display, Microsoft envisions its eventual uses as pervasive as imaginable, like ordering beverages from your restaurant table and silently scanning your wine bottle's RFID tag to automagically present information on the vineyard and vintage. Sure, some of it's pretty pie in the sky, but Microsoft is touting Surface's multi-touch, multi-user interface, object recognition and gestural interaction, and it's out to dispel myths of vaporware with limited 2007 rollouts in T-Mobile stores, Starwood hotels, and even Harrah's in Vegas.As for the consumer end of things, it's estimated that we're still a number of years out on the technology (for starters these Surface units are estimated to cost up to ten thousand bucks). Pretty steep for what ultimately amounts to being an underbelly projector with digital cameras that track surface interaction (all of which running on a stock 1GHz Vista box), but the focus of any nascent technology is never price, it's function.
