Abstract

See full text

A gyroscope-based device uses a probability model to assign probability of the device being in an intended static state to each received sample of gyroscope data. A new drift error compensation offset and new hand jitter factor are computed for each sample of gyroscope data based on the assigned probability. In this manner, the magnitude of the hand jitter factor varies with the probability of the device being in an intended static state.
