Touchscreens might be about to move up to the next level of cool if Apple has anything to do with it. Patents reveal Apple has been working on 3D gesture and 'physics metaphor' controls for its devices. The new "pinch and pull" input would allow you to create a 2D object using multi-touch then lift or twist your fingers to form or manipulate a 3D object. And with 'physics metaphor' controls, you could share files between an iPhone and iPad by actions – for instance, pouring files from one to the other or hoovering files up from another device (hopefully with a suitable turbine sound effect). How much more fun can gadgets get?
