The '''Snapdragon XR2 HMD Reference Design''' is an extended reality (XR) reference platform developed by [[Qualcomm]]. Unveiled in February 2020, it is the world's first 5G-enabled XR reference design, combining the Snapdragon XR2 platform with the Snapdragon X55 5G modem. The reference design provides hardware manufacturers with guidelines for building high-performance XR headsets, supporting displays up to 3K x 3K per eye at 90 Hz, seven simultaneous camera feeds, and advanced tracking technologies including eye tracking, hand tracking, and electromagnetic controller tracking.<ref name="qualcomm">{{cite web|url=https://www.qualcomm.com/news/releases/2020/02/qualcomm-accelerates-xr-headset-development-new-qualcomm-snapdragon-xr2-5g|title=Qualcomm Accelerates XR Headset Development with the new Qualcomm Snapdragon XR2 5G Reference Design|publisher=Qualcomm}}</ref>

== History and Development ==

=== February 2020 Announcement ===
Qualcomm unveiled the XR2 reference design to accelerate development of next-generation XR headsets with 5G connectivity.

=== Purpose ===
Reference designs serve as guidelines for hardware manufacturers, specifying compatible displays, cameras, and other components that work optimally with the Snapdragon XR2 chipset.<ref name="roadtovr">{{cite web|url=https://www.roadtovr.com/qualcomm-snapdragon-xr2-reference-design-vrdk-vr-ar-headset/|title=Qualcomm Reveals New Reference Designs for XR2-powered VR & AR Headsets|publisher=Road to VR}}</ref>

=== Manufacturing Partners ===
The reference design is manufactured by Thundercomm, Qualcomm's joint venture partner for development kits.
