Nokia has just filed a patent application known as “Mobile device with virtual keyboard”, and we can guess as much from there that the digital camera located on the handset is used to capture the movement and position of the user's fingers, projecting them onto a virtual keyboard which is shown on the phone's display in real time. I'd say such an application will see your cell phone's battery drained in no time, and is the camera fast enough to capture the image of a speed typist? Should this idea make it big, you will probably see a limitation in cell phone designs as the cameras can only be placed at a certain place on the handset in order for it to work nicely.
