All this while, you are only limited by the number of fingers you can use whenever you use a touchscreen phone. But there's a new technology that soon be able to tell the difference between fingertip, fingernail and knuckle.
That is what Chris Harrison, a computer scientist at Carnegie Mellon University in Pittsburgh managed to modify a Samsung Galaxy SIII to integrate input from all three different touchscreen variations. Imagine this: a fingertip that could let you select an object from the screen, while a knuckle tap could act like a right-click on a mouse and show a sub-menu. Pretty cool, eh?
Chris Harrison has already started a company called Qeexo, where he starts selling the new technology. According to him, the vibration sensor could easily be added to any smartphone's guts.
Anyway, check out the demo video below:
