While sending video from an iPhone to an external screen isn't anything new, Romin's setup allows the second touchscreen to control iOS thanks to a clever bit of software called Centrafuse. This enables the iPhone screen to not only be mirrored onto the larger touchscreen, but things like YouTube videos utilize the entire screen with the iPhone acting as the controller. Navigation, streaming music and POI browsing are just a few of the obvious uses, and Romin is intent on getting the setup into his own car soon. Check out the – admittedly rough – demo below for a closer look and keep in mind this could work with nearly any touch-based UI.
