Abstract
A sequence of tracking input samples that are measures of position or orientation of a user interface device, UID, being held by a user, are received. In a prediction phase, a current output sample of a state of linear quadratic estimator, LQE, is computed that is an estimate of the position or orientation of the UID. The current output sample is computed based on i) a previously computed output sample, and ii) a velocity term. In an update phase, an updated output sample of the state of the LQE is computed, based on i) a previously computed output sample from the prediction phase, and ii) a most recent tracking input sample. Other embodiments are also described and claimed.
