Multi-DOF inertial MEMS: From gaming to dead reckoning

This paper presents an overview of multi degrees-of-freedom (DOF) inertial MEMS in applications ranging from gaming to dead reckoning. Approaches to the implementation of high-performance inertial measurement units (IMU) are examined, focusing on challenges related to tri-axial gyroscope implementation. Benefits and tradeoffs of homogeneous multi-axis sensors are reviewed and contrasted with advances in single-chip integrated IMUs.
