6DoF Tracking

Definition

6DoF tracking refers to the ability to track an object's position and orientation in three-dimensional space, capturing both its translational movements (up/down, left/right, forward/backward) and rotational movements (pitch, yaw, roll). This capability is crucial for creating immersive experiences in virtual and augmented reality, allowing users to interact with digital environments in a natural and intuitive way.
