Microsoft Hololens is an untethered holographic computer running on Windows 10 that uses mixed reality to project holograms onto the transparent display using sensors and mapping algorithms. It features a Kinect, battery, cameras, speakers, and 18 sensors to track gestures, gaze and voice commands to interact with holograms in a blended physical and virtual environment. Hololens allows for new ways of teaching, learning, entertainment and exploration without cords or wires through its transparent and adjustable design.
