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 Linux-based [[virtual reality]] [[head-mounted display]] developed by [[SimulaVR]]. Priced at $2,699, the Simula One is uniquely designed for programmers and developers who use Linux professionally, featuring an Intel Core i7 processor (x86 architecture) rather than ARM-based mobile chips. The headset runs SimulaOS, a custom VR Linux distribution built on NixOS with a Godot-based VR window manager, allowing unlimited Linux desktop applications to run natively in VR. The display achieves 35 PPD in the foveal region using three-element non-Fresnel optics with 2448 x 2448 per eye resolution.<ref name="roadtovr">{{cite web|url=https://www.roadtovr.com/simula-one-linux-vr-headset-kickstarter/|title=Simula One is a Standalone VR Headset Natively Running Linux Desktop|publisher=Road to VR}}</ref>
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"/>


==History==
== History and Development ==
SimulaVR was founded in 2020 by George Singer, David Kraeutmann, and Carl C. Wheeler III.<ref name="tracxn"/> The company initially focused on developing Simula, an open-source [[VR window manager]] for Linux, compatible with existing [[SteamVR]] headsets like the [[HTC Vive]] and [[Valve Index]].<ref name="github-simula"/> This project evolved into creating a dedicated hardware solution due to the perceived lack of Linux support from other VR manufacturers.


The Simula One headset was first announced on December 15, 2021, with an initial plan to launch a [[Kickstarter]] campaign in January 2022.<ref name="roadtovr2021"/> However, on February 14, 2022, SimulaVR announced they would forgo Kickstarter in favor of direct preorders, citing cost savings and greater flexibility.<ref name="roadtovr-preorders"/> Initial shipping estimates were for Q4 2022, but the project faced several delays, pushing estimates through 2023 and 2024.<ref name="headsets-delayed-2024"/> As of May 2025, headsets are expected to begin shipping, with priority for Founders Edition preorders.<ref name="shop-simulavr-may2025-status"/>
=== 2021 Announcement ===
SimulaVR announced the Simula One, targeting developers and Linux professionals.


==Design==
=== Kickstarter Campaign ===
===Industrial Design===
The project moved from Kickstarter to direct pre-orders in 2022.
The Simula One features a distinctive retro-futuristic aesthetic, with a large visor reminiscent of early home computers like the [[Magnavox Odyssey]] or [[Apple II]].<ref name="first-glimpse-retro-design"/> It includes a detachable rear "compute pack" which houses the main processing components and battery. This design helps balance the headset's weight for improved comfort during extended use and allows for potential [[Central processing unit|CPU]] and other component upgrades in the future without replacing the entire HMD.<ref name="displaydaily2022"/>

The Simula One is a standalone Linux-based virtual reality head-mounted display developed by SimulaVR. Priced at $2,699, the Simula One is uniquely designed for programmers and developers who use Linux professionally, featuring an Intel Core i7 processor (x86 architecture) rather than ARM-based mobile chips. The headset runs SimulaOS, a custom VR Linux distribution built on NixOS with a Godot-based VR window manager, allowing unlimited Linux desktop applications to run natively in VR. The display achieves 35 PPD in the foveal region using three-element non-Fresnel optics with 2448 x 2448 per eye resolution.[1]
