[[Lighthouse]] is a [[positional tracking ]] system developed by [[Valve]] for [[SteamVR]]. It accurately tracks the position and orientation of the user's [[head-mounted Display]] and [[SteamVR Controllers|controllers]] in real time. Lighthouse enables the users to move anywhere and re-orient themselves in any position within the range of the [[SteamVR Base Stations]]. It is a key technology that enables [[SteamVR]] to create the first holodeck or full-room experience in [[Virtual Reality]].
