Tokyo University of Technology's Pinch interface creates ad hoc video walls from mobile devices Most video walls would be just a tad too large for the average living room, but the Tokyo University of Technology might have a clever technique to make them travel-sized. Its new Pinch interface joins mobile devices (currently iOS hardware) into a single display simply by making the namesake gesture between at least two gadgets: WiFi keeps them in sync and recognizes the relative size and orientation. While we probably wouldn't resort to a wall of iPads in place of a large TV, there's clear practical uses like extra-large creative apps, communication and very local multiplayer games. The best news may be that the university isn't keeping the technology to itself. It wants developers to borrow Pinch for their own apps, which could lead to a legion of smartphones and tablets getting extra-cozy.

How does Wifi recognize the location ??.. thats the biggest challenge for such a setup to accurately determine relative positioning each screen.
Wifi isn't recognizing the location, they are sending data (Regarding position and zoom level) and receiving it over WiFi.
So how is the location being measured then, the device would rely on some outside sensor to determine their locations. Sent from my MB526 using Tapatalk 2
How and why? I don'tt know exactly how they are doing it, but I don't see it being a problem once you know the sizes of the different displays.
