Microsoft HoloLens, known under development as Project Baraboo, is a pair of mixed reality smartglasses developed and manufactured by Microsoft. HoloLens gained popularity for being one of the first computers running the Windows Holographic platform under the Windows 10 operating system. The HoloLens can trace its lineage to Kinect, an add-on for Microsoft’s Xbox gaming console that was introduced in 2010.
The HoloLens is a head-mounted display unit connected to an adjustable, cushioned inner headband, which can tilt HoloLens up and down, as well as forward and backward.To wear the unit, the user fits the HoloLens on their head, using an adjustment wheel at the back of the headband to secure it around the crown, supporting and distributing the weight of the unit equally for comfort, before tilting the visor towards the front of the eyes.
The HoloLens features an inertial measurement unit (IMU) (which includes an accelerometer, gyroscope, and a magnetometer) four “environment understanding” sensors (two on each side), an energy-efficient depth camera with a 120°×120° angle of view,a 2.4-megapixel photographic video camera, a four-microphone array, and an ambient light sensor.
