Not content with synchronizing your phones to make one giant speaker? Researchers at the Tokyo University of Technology have developed "Pinch," an interface that lets you connect multiple devices together to form a giant disjointed display. Although the technology behind the interface remains a mystery — described only as a Wi-Fi based system — a video posted by DigInfo TV shows Pinch in action. To connect two devices, a user simply needs to pinch two adjacent screens together. The screens can be linked together in whatever alignment you choose, as the position and screen size of each display is communicated on a successful pinch. It's not the first time developers have managed to link together multiple smartphone displays, but this is definitely the slickest interface we've seen.

Takashi Ohta, Associate Professor at Tokyo University of Technology, envisions the Pinch interface being used for a variety of apps. "People probably own just one of these devices each. I think people could communicate in fun ways by getting together with friends and putting their devices next to each other." Potential uses include music, advertising, and photo sharing — although depending on how fast the tech is we'd love to see some games take advantage of the interface. The research team is offering Pinch to interested developers and says that several have already taken them up on the offer.
