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''' was a cancelled PC VR [[head-mounted display]] announced by [[Deca]] (Megadodo Simulation Games), a Singapore-based company. Unveiled in November 2020, the DecaGear promised an ambitious feature set including 2160 x 2160 per eye resolution, 114-degree field of view, face tracking with 52 FACS blendshapes, Index-style controllers with finger tracking, a hip tracker called DecaMove, and optional wireless module—all for $449. Despite initial excitement and Valve confirmation of the product's legitimacy, the project was ultimately cancelled without shipping to consumers.<ref name="roadtovr">{{cite web|url=https://www.roadtovr.com/decagear-vr-headset-megadodo-simulation-games/|title=DecaGear PC VR Headset|publisher=Road to VR}}</ref>
