I purchased an alienware 15 r3 which comes with Windows Hello enabled which means all hardware included.
Windows Hello is basically a face detection system added on Win10. It works with dual-camera and a laser pointer (dual-camera for 3 dimensions and laser for measuring profundity). It logs me in as soon as the camera (entire set) sees me. Also it can be used as an advanced face recognition security accessory that can store my password and use it only when I am there. Its pretty accurate even in low light (and even no light) because of the infrared that comes in the set.
I have installed Ubuntu 16.04 and couldn't find any package that can substitute for Windows Hello. Please give me a good alternative which can login using face detection and also make use of the infrared in the hardware for detection in low light.
