The '''DecaGear''' was a cancelled PC-tethered [[virtual reality]] [[head-mounted display]] announced by [[Megadodo Simulation Games]] (Deca) from Singapore in September 2020 at $449. Promised high-end specifications including 2160x2160 per eye RGB LCD, 114° FOV, face tracking (FaceFlow with 52 blendshapes), Index-style controllers with finger sensors, hip tracking module (DecaMove), and wireless adapter (DecaAir). Never released despite pre-orders.
The '''DecaGear''' (also known as DecaGear 1) was a cancelled [[PC VR]] [[head-mounted display]] announced by Singapore-based company [[Deca]] (part of Megadodo Simulation Games) in November 2020, with a planned price of $449 and an originally announced Q2 2021 release that was subsequently delayed to Q4 2021 before the project was ultimately cancelled. The DecaGear generated significant excitement in the VR community with its ambitious specifications at an aggressive price point: 2160 × 2160 resolution per eye (matching the HP Reverb G2), 114° field of view, 90Hz refresh rate, inside-out 6DoF tracking with four cameras providing 225° controller tracking volume, and integrated face tracking technology called "FaceFlow" using two infrared cameras to track 52 FACS-standard facial blendshapes. Additional planned accessories included the DecaMove hip tracker for body-facing locomotion and the DecaAir $49 wireless adapter. Valve confirmed the headset's legitimacy as a SteamVR-compatible device, but despite initial pre-orders and development progress, the project was never completed and no units shipped to consumers.
 
'''Note: The DecaGear project was cancelled and no units were ever commercially released. This article documents the announced specifications of the unreleased product.'''


== History and Development ==
== History and Development ==


Megadodo Simulation Games announced the DecaGear in September 2020 as an affordable alternative to high-end PC VR headsets. Targeting $449 (undercutting HP Reverb G2), the headset promised competitive specifications with innovative features like integrated face tracking. Valve confirmed the SteamVR partnership, lending credibility. Originally targeting May 2021 shipment, delays pushed to Q4 2021. The project was ultimately cancelled without shipping any units to customers.<ref name="uploadvr">{{cite web |url=https://www.uploadvr.com/decagear-steamvr-headset/ |title=Valve Confirms DecaGear SteamVR Headset |publisher=UploadVR |access-date=2025-01-07}}</ref>
