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.
