Kalman filter

A Kalman filter is a filter that uses sensor data prediction to produce a stable data stream from noisy sources. It crushes and removes the high frequency data if the predictor is not programmed properly. This happens in SteamVR and Meta Quest headsets.

The EKF is an extended kalman filter. This gives higher quality results than a normal Kalman filter.

The UKF is an unscented kalman filter. This can be better than EKF.

A related type of filter is Particle filter.

Kalman filters filter all the life out of movement.
