Microsoft HoloLens 1
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.[1]
