A Display That Tracks Your Movements

Movement tracking display - gesture interface ...

"There could be a revolution brewing in billboard advertising. Instead of simply presenting a static image, why not let people interact with the advertisement? This is the vision of electronics giant Samsung and interactive advertising company Reactrix Systems. The two companies have partnered to bring 57-inch interactive displays to Hilton hotel lobbies by the end of the year. These displays can "see" people standing up to 15 feet away from the screen as they wave their hands to play games, navigate menus, and use maps.

With the buzz surrounding the Wii, the iPhone, and Microsoft's Surface, "people are more open and ready to interact using their hands and gestures," says Matt Bell, chief scientist and founder of Reactrix. It's easy to see how a gesture-based interface might work well for video games and virtual worlds, and certainly companies such as Belgian startup Softkinetic make systems for those very needs. But Reactrix is aiming for the out-of-home advertising market, traditionally dominated by large static displays like billboards. Founded in 2001, Reactrix has some experience already: today, its interactive floor displays attract crowds in shopping centers across the country.

The basic idea behind Reactrix's system, and even low-end gesture-based technologies such as the Sony PlayStation Eye, is to use a camera to detect a person's body, and then use computer vision algorithms to make sense of the images. Reactrix and Softkinetic systems differ from the PlayStation Eye, however, in that they record 3-D information as opposed to just two-dimensional information."    (Continued via Technology Review, Kate Greene)    [Usability Resources]
