Questions tagged [hololens]

Applicable for all questions related to development for Microsoft HoloLens devices and the Mixed Reality platform.

Microsoft HoloLens, is a pair of mixed reality head-mounted smartglasses developed and manufactured by Microsoft Corporation. HoloLens gained popularity for being one of the first computers running the Windows Holographic platform under the Windows 10 operating system. HoloLens 1 was released in 2016 and is no longer available. HoloLens 2 is expected end of 2019 and available for preorder through Microsoft.

Developing apps for HoloLens can be done through Unity and of course DirectX. Because the device is not publicly available, you will need to purchase a developer kit to test applications you develop, although there is a HoloLens emulator that comes through the development overview.
