Nokia files patent for on-screen QWERTY keyboard

Nokia has filed a patent for a "Mobile device with virtual keyboard", which is designed to solve the problem of placing a full thumbboard on a tiny handset. The idea behind this scheme is to use the abilities of the phone itself to imitate a virtual keyboard, and that's the way it should work: the phone's bundled camera will capture all your fingers' wrigglings on any flat surface, while specially designed sensors will catch sounds or vibrations. Using a desktop cradle you will be able to have your phone in the upright position, although it is not obligatory to use this technology. The patent application also claims that the users will be allowed to just hold his device in the hands and type literally in the air, and just utter certain sounds himself (although it is not very clear how it will work out in real life). The virtual keyboard, along with the user's fingers, will be rendered on the phone's screen in real time, while all entered symbols will be popping up on the screen.
