Abstract
Various embodiments of the invention provide for automatic, real-time bias detection and error compensation in inertial MEMS sensors often used in handheld devices. Real-time bias correction provides for computational advantages that lead to optimized gyroscope performance without negatively affecting user experience. In various embodiments, bias non-idealities are compensated by utilizing raw output data from the gyroscope itself without relying on additional external sensors.
