Researchers at Newcastle University, along with Microsoft, have jointly developed a motion sensor which can be worn on the wrist. The motion sensor allows the user to control almost any device with the wave of a hand.
The new device is called ‘Digits’ and uses infrared technology and a tiny camera which maps out 3D finger movement and translates it into commands. An example of the functionality of the device is being able to zoom in and out of a tablet by just a wave of the hand. David Kim, a Newcastle University student said that the Digits sensor does not rely on any external infrastructure.
