Sony previews prototype Xperia gadgets

Sony is looking at taking the Xperia brand beyond smartphones and is showing off some prototype gadgets at the IFA trade show in Berlin. It was keen to underline that not all of them might make it to manufacturing, but those on display were fully working prototypes with hardware and software stable enough that the company let a reporter test them out. This is an Android-based computer with a short-throw projector in a single box. The projector sends the screen image onto a nearby tabletop or wall and users can interact with it by using their fingers on the projected image. An infrared sensor in the device watches the fingers and figures out where they are pressing on the projected screen.
