Howto: Use Unreal Engine 5.1 for XR Development
XR refers to: Augmented, Virtual, and Mixed Realities
On this page
˚₊· ͟͟͞͞➳❥ XR mean the experiences:
Augmented reality: digital info (yknow’ images, gifs, text) overlays my view of the real world through handheld devices like smartphones or wearable devices like smart glasses.
Virtual reality: virtual world replaces my view of the real world letting me interact with and navigate the virtual environment as if it were real through a wearable device.
Mixed reality: elements of both AR and VR creates an experience where my virtual objects interact with the real world in a seamless way through the use of head-mounted display (HMD) devices like Microsoft HoloLens or Magic Leap One.
Unreal Engine supports both developing for XR platforms and using XR devices. The sections below links to documentation on how to work with XR devices in your projects.

OpenXR is a royalty-free, open standard that provides high-performance access to XR platforms and devices. With OpenXR, you can create an immersive experience in Unreal Engine that can run on any system that supports the OpenXR APIs. Currently, OpenXR in Unreal Engine only supports head-mounted devices.
This section describes how OpenXR works in Unreal Engine.
