Wearable Mobile Device is an interesting conceptual prototype that is presented as a sort of belt to wear with a hand to turn it into a kind of computer-communicator.
This device is extremely lightweight and flexible, is applied on the hand for a system that does not ask for nothing but the hand itself. Acting on the fingers will instruct the internal processor can "see" through a sensor / projector double on.
The band is a low-power fold-able display, can display the messages just received, but obviously the possibility of expansion and the potential is limitless.
