Microsoft HoloLens, known under development as Project Baraboo, is a pair of mixed reality head-mounted 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 pre-production version of HoloLens, the Development Edition, shipped on 30 March 2016, and is targeted to developers in the United States and Canada for a list price of $3,000. Samsung and Asus have extended an offer to Microsoft to help produce their own mixed-reality products, in collaboration with Microsoft, based around the concept and hardware on HoloLens.
