We have seen a number of examples over the years where lasers are used to give the keyboard on a flat surface, and therefore this command enables users to write using the virtual keyboard so that the device can identify what the user intends to type it. But what if the laser keyboards, virtual keyboards is wholly unnecessary, and by allowing our smart phones and our tablet to watch our fingers to translate what we want to write? This is exactly what the Japanese company Fujitsu trying to review through one of the forms provided by the Mobile World Congress held in Barcelona, Spain.
This model works by using a range of programs and relying on the front camera of the device tablet, Fujitsu has developed way for users to write simply on a smooth flat, through the possibility of known tablet on your hands as well as fingers that you use for writing.
