World tracking enables augmented reality devices to understand their location within a physical space and keep digital 3D models anchored in their surroundings.

Mobile devices and AR headsets analyze camera frames and motion sensor data every moment to track how a device is moving around. This facilitates six degrees of freedom tracking, and allows AR content to be anchored in space.

World tracking enables an artist to add digital paintings all around an art gallery. The AR artwork stays in place as viewers move around the space. Even when visitors come return the next day, the content is still anchored in the same location.

World tracking is a foundational technology for believable augmented reality. By understanding where a user is in space, the digital objects can stay fixed and react naturally to the user.
