An Israeli startup has launched a system that aims to make mobile computing easier by letting users type on invisible keys instead of a keyboard that typically takes up much of the screen.
The keyboard has four invisible keys -- two on each side of the device's screen -- each comprising six to seven letters. There are other keys for numbers, punctuation and symbols.
At first, the location of the keys appears on the screen but the company believes users will quickly learn the location of letters and will not need the overlay for long. Users tap the invisible keys with their thumbs and the system predicts the words.
And screens are not supposed to be your input device; they are supposed to be output
I think this is the main fault in their way of thinking why the invisible keyboard would be a success. People like some kind of interaction. Light pens and touch screens have been there for decades and with the current generation of mobile devices, the number of devices with touch screens may well go beyond the number of devices with regular keyboards.
