Microsoft has revealed its next wave of motion control technology with Digits: a bracelet device that takes gesture input from a human hand and renders it in real time 3D.
Microsoft has already gained a strong foothold in motion control technology with the Kinect, and with the Digits bracelet it adds fine motor control -where the kinect has serious trouble- to its arsenal.

Developers working with the device will have a new frontier of interface options available to them like gesture-based controls in games, sign-based typing, and even turning the pages on an e-reader as if they were three dimensional objects.
To enhance the user's immersion and sense of control, the device also renders the hand in real-time 3D.
Digits can even keep track of all this while the user is moving around- an obstacle many rival systems have failed to overcome.
