Virtual keyboard idea from Nokia
Nowadays a great amount of people type something. It’s not important whether it’s a poem, essay, SMS or something else. Some type using their PC keyboard, others use that of their cell phones. Because of this both producers and designers try to make this process simpler by inventing various types of keyboards (for example, wireless small keyboard featuring Bluetooth).
Nokia as many others trying to invent something absolutely new and different has just filled a patent application known as “mobile device with virtual keyboard”. We can guess as much from there that the digital camera located at the back of the cell phone 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.
It sounds really interesting but it’s not the fact that it will be easier to type on such a virtual keyboard than on a usual one. Moreover, I think that such an application will make your cell phone’s battery drained in no time, and the camera wouldn’t be fast enough to capture the image of a speed typist. Another significant problem consists in the fact that there would probably be some limitations 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.
