In 2013, Apple bought PrimeSense. Depth cameras continued to evolve: Kinect 2.0 for the Xbox One replaced PrimeSense technology with Microsoft's own tech and had much higher accuracy and resolution. It could recognize faces and even detect a player's heart rate. Meanwhile, Intel also built its own depth sensor, Intel RealSense, and in 2015 worked with Microsoft to power Windows Hello. In 2016, Lenovo launched the Phab 2 Pro, the first phone to carry Google's Tango technology for augmented reality and machine vision, which is also based on infrared depth detection.
