'''DecaGear''' is a [[virtual reality]] [[head-mounted display]] that was cancelled before release.
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.
