Video gaming with a difference comes in various forms and approaches, but I quite like the idea of controlling games with the use of a tablet. This is is the RoboTouch and it uses the old NES controller accompanied with a Arduino board. As you press the control buttons on the NES pad, the arms then simulate the touch of fingers on the ipad screen.
I know it seems like a long way to go about it, but it’s still pretty inventive. It was designed by Joven of ProtoDojo.
