You will be forgiven in thinking that this is some sort of robotic arm or something similar. It is in fact something called the PossessedHand, which is a device that can take control of the user’s hand, such as making the fingers move independently from the rest the body.
The technology is being developed by teams of researchers from The University of Tokyo and Sony Electronics, the idea is that the system will be able to train the hand to learn complicated tasks, such as learning to play instruments. but with Sony being involved here you have to think that they are looking at it as being some sort of next gen games controller!
The system is made up with a couple of wrist bands, which produce a weak electrical charge; this stimulates the muscles and moves the fingers.
