| Accelerometers measure linear acceleration in three axes (X, Y, Z), while gyroscopes are sensors that measure angular velocity around three axes (X, Y, Z). Magnetometers measure the strength of a magnetic field in three axes (X, Y, Z). Combined, you get position, translational and rotational information about a segment. These signals are fused to estimate the pose of the associated segment. | Accelerometers measure linear acceleration in three axes (X, Y, Z), while gyroscopes are sensors that measure angular velocity around three axes (X, Y, Z).

| Visual3D extracts the pose information from IMU systems that write out an MVNX file. **It does not read in the raw IMU data.** | Visual3D extracts the pose information from IMU systems that write out an MVNX file. **It does not read in the raw IMU data.** | ||
