Definition
The Valve Index is a high‑performance virtual reality (VR) headset and controller system developed by Valve Corporation. It is part of the SteamVR platform and is marketed as a premium consumer headset for immersive gaming and simulation experiences.
Overview
Announced in March 2019 and released later that year, the Valve Index comprises a head‑mounted display (HMD), a pair of external “Index Controllers” (formerly known as “Knuckles”), and two SteamVR 2.0 base stations for outside‑in tracking. The system is sold as a bundled kit or as separate components. Designed to work with PC hardware running the Steam operating system, the Index targets enthusiasts seeking higher refresh rates, wider field of view, and advanced hand‑tracking compared with earlier consumer VR devices.
Etymology/Origin
The name combines “Valve,” the developer’s corporate brand, with “Index,” a term traditionally meaning a pointer or guide, likely intended to convey the headset’s role as an interface to virtual environments. The product’s development originated within Valve’s hardware division, which previously produced the HTC Vive in partnership with HTC.
