Essentially, the iPhone establishes a connection with the computer, then it can control the OS in a similar manner to a TV remote. Using a virtual d-pad, users navigate through apps, open them remotely and even print. But what’s possibly more promising that buttoning around an OS is that voice commands could be deployed to skip many of these navigational hassles.
Apple’s Remote app, which allows the control of iTunes over a local network, is still one of my favourite apps on the iPhone. If Apple were to evolve that app into what we see in this patent, it’d only become more handy. [Patently Apple via 9to5Mac]
