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.
