The '''DecaGear''' was a cancelled [[PC VR]] [[head-mounted display]] announced by [[Megadodo Simulation Games]] in October 2020. The headset was notable for its ambitious feature set at a low price point, including face tracking, hip tracking (via the DecaMove accessory), and Index-style controllers with finger tracking, all for $450. After multiple delays due to the global semiconductor shortage and rising component costs, the project went silent in late 2021 and is presumed cancelled.
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.'''

In November 2021, co-founder and CEO Or Kuntzman warned that the global semiconductor shortage made the $450 price point no longer viable:
== Display Technology (Announced) ==


"Even if we solve the financial issues and produce the headset as is, its current price is ~$700, more than double the cost of the Quest 2."

After this announcement, Megadodo went into radio silence. Kuntzman stopped posting on social media, and the project's website eventually went offline. The status of the 10,000+ pre-orders remains unclear.<ref name="uploadvr2">{{cite web |url=https://www.uploadvr.com/decagear-pivot-chip-shortage-delay/ |title=DecaGear To 'Pivot', Warning Of $700 Viable Price & Late 2022 Shipping |publisher=UploadVR |access-date=2025-01-07}}</ref>

The DecaGear represented an ambitious attempt to bring premium VR features to a mid-range price point. While the project failed due to market conditions, several of its promised features (face tracking, hip tracking) have since been implemented in other products or remain areas of active development in the VR industry.
== Technical Specifications Summary (Announced) ==


The project serves as a cautionary example of the challenges facing hardware startups during supply chain disruptions, and the importance of managing consumer expectations through pre-order campaigns.<ref name="arvrtips">{{cite web |url=https://arvrtips.com/decagear-vr-headset/ |title=DecaGear VR Headset: Everything We Know So Far! |publisher=ARVRtips |access-date=2025-01-07}}</ref>
