Abstract

A hand-held processor system for processing data from an integrated MEMS device disposed within a hand-held computer system and method. A dynamic offset correction (DOC) process computes 3-axis accelerometer biases without needing to know the orientation of the device. Arbitrary output biases can be corrected to ensure consistent performance A system of linear equations is formed using basic observations of gravity measurements by an acceleration measuring device, conditioned upon constraints in data quality, degree of sensed motion, duration, and time separation. This system of equations is modified and solved when appropriate geometric diversity conditions are met.
