A Wrist Worn Device that Allows You to Control Your Gadgets
Ever wish you could answer a call, turn up the volume, or play your favorite video game using just hand gestures? Enter Microsoft Digits, a wrist-worn sensor that turns your hand gestures into virtual movements with the use of small cameras and IR sensors. Digits allows you to interact with various gadgets wherever you go, all from the one device. As of now, Digits prototype is a bit large and cumbersome, however developers are working to reduce the size of the unit making it more practical for every day use.
How it works:
An infrared (IR) camera sensor located on the device detects an IR beam emitted from the device. The camera sensor detects the distance to the user’s fingers to determine how the hand is bent. Additional rings of IR LED’s illuminate the hand to determine the position and direction of the hand. Software then uses the data to construct a real-time 3D model of the hand. Because the sensors are located on the device, the user has no range restrictions, allowing them to move about freely.
