[[Microsoft HoloLens]] is an [[augmented reality headset]] developed by [[Microsoft]]. It is part of the [[Windows Mixed Reality]] [[AR Platform]] incorporated with [[Windows 10]] OS. HoloLens is an optical see-through head-mounted display. It may be similar to other [[OHMD]]s (optical head-mounted displays). Unlike the [[Oculus Rift]] and other [[Virtual Reality#Devices|VR Devices]], the eye-piece component of HoloLens is transparent and the headset requires neither PC nor smartphone. It is able to project high-definition (HD) virtual content over real world objects. <ref name=”one”>Microsoft. Microsoft HoloLens.

==Announcement and Release== | |||
Microsoft HoloLens was announced during a Windows 10 Event on January 21st, 2015. The Development Edition was released on March 30, 2016, for $3,000 or £2,000. It allowed developers to start making apps and games for the headset. Months later, it became available to anyone with a Microsoft account. During the last quarter of 2016, the program expanded beyond the United States into countries like the United Kingdom, Ireland, France, Germany, Australia and New Zealand. Currently, there’s still no information regarding a consumer edition release date. <ref name=”three”>Sophie, C. (2017). Microsoft HoloLens: Everything you need to know about the $3,000 AR headset.

The transparent dual displays are made of three layers of glass (red, blue and green). A light engine is mounted above the displays and projects light on the lenses. The tiny corrugated grooves in each layer of glass diffract these light particles, making them bounce around and helping to trick your eyes into perceiving virtual objects at virtual distances. | The transparent dual displays are made of three layers of glass (red, blue and green).
