Project Digits
Project Digits is a Microsoft Research Project under Microsoft's computer science laboratory at the University of Cambridge; researchers from Newcastle University and University of Crete are also involved in this project.〔 Project is led by David Kim a Microsoft Research PhD and also a PhD Student in computer science at Newcastle University. Digits is an input device which can be mounted on the wrist of human hand and it captures and displays a complete 3D graphical representation of the user's hand on screen without using any external sensing device or hand covering material like data gloves. This project aims to make gesture controlled interfaces completely hands free with greater mobility and accuracy. It allows user to interact with whatever hardware while moving from room to room or walking down the street without any line of sight connection with the hardware.
==Prototype==
Prototype of the device was displayed at a conference on user interface technology in Massachusetts on 9 October 2012.
System is created using off the shelf hardware and consumes low power.
The Device uses Infrared-Camera sensor which detects infra-red light and then the data is fed to the software which interprets it to create a 3D model of the human hand. Data changes according to the position of real hand and then so does the 3D representation also. The Infra-red laser beam is used to determine the distance to fingers and thumbs to obtain the accurate orientation of the hands. Further, Infra–red LED’s helps to determine the exact position of the fingertips, as the light bounced back from fingers is captured by the camera. One of the benefits of IR LED is that human eye cannot detect it, hence it does not disturbs the user while using the device. "Ultimately we would like to reduce Digits to the size of a watch that can be worn all the time, We want users to be able to interact spontaneously with their electronic devices using simple gestures and not even have to reach for their devices." Quoted by David Kim Project Leader.〔
