The '''Microsoft HoloLens''' (1st generation) is a standalone [[mixed reality]] [[head-mounted display]] developed by [[Microsoft]], announced in January 2015 and released on March 30, 2016 at $3,000 for developers. HoloLens was the first self-contained holographic computer, featuring see-through waveguide displays, spatial mapping, hand gesture recognition, and voice commands, all powered by a custom Holographic Processing Unit (HPU) alongside an Intel Atom processor. Despite a limited 30-degree field of view, HoloLens pioneered enterprise AR applications and demonstrated the potential of untethered mixed reality computing.<ref name="microsoft">{{cite web|url=https://en.wikipedia.org/wiki/Microsoft_HoloLens|title=Microsoft HoloLens|publisher=Wikipedia}}</ref>
The '''Microsoft HoloLens''' (1st Generation) is a self-contained [[mixed reality]] [[head-mounted display]] developed by [[Microsoft]], announced on January 21, 2015, at a Windows 10 event, and released as the Development Edition on March 30, 2016, for $3,000. HoloLens was the first completely self-contained holographic computer—requiring no wires, phone, or PC—capable of projecting interactive 3D holograms onto the real world through see-through waveguide displays. Powered by an Intel Atom processor and Microsoft's custom Holographic Processing Unit (HPU), HoloLens could understand the user's environment through spatial mapping, recognize gestures and voice commands, and anchor digital content to physical locations. Though limited by its narrow 30° diagonal field of view, HoloLens pioneered the concept of spatial computing for enterprise applications in manufacturing, healthcare, construction, and education.
