The '''Simula One''' is a [[standalone VR|standalone]] [[virtual reality]] (VR) [[head-mounted display]] (HMD) developed by [[SimulaVR]]. Unlike mainstream gaming-focused devices, it is marketed as a "[[VR Computer]]" (VRC) designed specifically for productivity, office work, and software development, particularly for users who prefer a [[Linux]] environment.<ref name="roadtovr-announce"/> It ships with [[SimulaOS]], an [[open-source software|open-source]] Linux [[Distribution|distribution]] built for immersive desktop workspaces.<ref name="simulavr-main"/> <ref name="uploadvr2022"/>


==Overview==
The '''Simula One''' is a standalone [[virtual reality]] and [[mixed reality]] [[head-mounted display]] developed by [[SimulaVR]], announced in 2022 with pre-orders at $2,699 and originally planned for shipping no earlier than Q4 2023. The Simula One is uniquely positioned as a "portable Linux VR computer," natively running SimulaOS (built on NixOS and the Godot game engine) to serve as a complete virtual reality workstation—targeting programmers, software engineers, and developers who use Linux professionally rather than gamers. The headset features an impressive 35.5-36.2 PPD (pixels per degree), higher than any other portable VR headset at announcement, achieved with 2448 × 2448 per eye resolution, custom non-Fresnel 3-lens optics, and a 100° diagonal field of view. Powered by a detachable rear compute pack containing an Intel Core i7-1365U processor, Intel Iris Xe graphics, 16-32GB RAM, and 1TB SSD, the modular design allows theoretical future upgrades without replacing the entire headset. The Simula One includes 6DoF tracking, eye tracking, hand tracking, dual RGB cameras for AR passthrough, and extensive connectivity (USB4/Thunderbolt 4, USB-C, USB-A)—and can be tethered to a Windows/Linux PC for SteamVR gaming when the compute pack is detached.
The Simula One aims to replace traditional [[laptop]]s and [[personal computer|desktop PCs]] for knowledge work by offering an unlimited virtual multi-monitor setup within VR.<ref name="technical-overview"/> It emphasizes text clarity, extended work sessions, and the ability to run standard Linux desktop applications in a [[virtual environment]].<ref name="hackernews-announce"/> The device features a detachable compute pack, allowing for potential future hardware upgrades.<ref name="displaydaily2022"/>

The Simula One is a standalone virtual reality and mixed reality head-mounted display developed by SimulaVR, announced in 2022 with pre-orders at $2,699 and originally planned for shipping no earlier than Q4 2023. The Simula One is uniquely positioned as a "portable Linux VR computer," natively running SimulaOS (built on NixOS and the Godot game engine) to serve as a complete virtual reality workstation—targeting programmers, software engineers, and developers who use Linux professionally rather than gamers. The headset features an impressive 35.5-36.2 PPD (pixels per degree), higher than any other portable VR headset at announcement, achieved with 2448 × 2448 per eye resolution, custom non-Fresnel 3-lens optics, and a 100° diagonal field of view. Powered by a detachable rear compute pack containing an Intel Core i7-1365U processor, Intel Iris Xe graphics, 16-32GB RAM, and 1TB SSD, the modular design allows theoretical future upgrades without replacing the entire headset. The Simula One includes 6DoF tracking, eye tracking, hand tracking, dual RGB cameras for AR passthrough, and extensive connectivity (USB4/Thunderbolt 4, USB-C, USB-A)—and can be tethered to a Windows/Linux PC for SteamVR gaming when the compute pack is detached.
