The HoloLens 2 is a mixed-reality/augmented-reality headset, released by Microsoft in 2019. Microsoft recommends tools such as Unity, Unreal, and Vuforia to create mixed-reality experiences in both 2D and 3D, that can be run by the HoloLens. The HoloLens features an inertial measurement unit (consisting of an accelerometer, a gyroscope, and a magnetometer), four “environment understanding” sensors, an energy-efficient depth camera with a 120°×120° angle of view, a 2.4-megapixel video camera, a four-microphone array, and an ambient light sensor. It also features both the ability to do hand-tracking and eye-tracking. Commercially, it is commonly used by electricians, and those wokring in construction – fields where adding a layer of technical details on top of reality can be of great value.
