| The [[Varjo XR-4]] is a professional [[PC-Powered VR|PC-powered]] [[mixed reality]] and [[virtual reality]] [[head-mounted display]] announced on November 27, 2023, by [[Varjo|Varjo Technologies]].<ref name="varjo-xr4-product" /> Representing the fourth generation of Varjo's mixed reality technology, the XR-4 series eliminated subscription requirements, introduced inside-out tracking as standard, and offered professional-grade specifications at a revised price point for its class.<ref name="varjo-announcement" />
| |
| ==History==
| |
| The XR-4 development began in 2022 following feedback from [[Varjo XR-3]] customers and success of the subscription-free [[Varjo Aero]]. Key development goals included democratizing professional mixed reality, aiming for high visual fidelity in both virtual and passthrough modes, and eliminating external tracking requirements.<ref name="cnbc" />
| |
| ===Major Improvements over XR-3===
| |
| *51 PPD uniform resolution (vs dual-display system)
| |
| *20-megapixel [[passthrough cameras]] (vs 12MP)
| |
