The technology that enables virtual reality (VR) headsets to track user movement typically involves a combination of motion sensors, gyroscopes, and infrared cameras. These sensors detect the user's head position and orientation in real time, translating physical movements into a virtual environment. Additionally, some systems employ external tracking devices or base stations to enhance accuracy. This technology creates immersive experiences, allowing users to interact naturally with digital spaces, thus enriching their engagement and presence within virtual worlds.
