Touch Revolution, maker of projected capacitive touch screens, was showing off a number of prototype devices at CES 2011. What’s the potential for capacitive touch and Android devices? How about a training bicycle with built-in screen for interactive exercise programs, better in-flight entertainment for those cross-continental plane rides, and 32-inch multi-touch screens. Charbax has a video highlighting these prototype Android-powered touch screens. If and when we see this stuff available for sale is hard to say, but at least we know people are thinking about some interesting Android-powered use cases.
