MAGNETOMETERLESS DETECTION OF INCORRECT ATTACHMENT AND CALIBRATION OF MOTION TRACKING SYSTEM

A method for adjusting operation of a motion tracking system includes a computing apparatus and sensors, each sensor having a gyroscope and an accelerometer. The method includes the steps of aligning the sensors; providing, each sensor to the computing apparatus, a first orientation when the sensors are aligned, the first orientation having a first heading; placing the sensors on a person; and providing, each sensor to the computing apparatus, a second orientation when the sensors are placed on the person, the second orientation having a second heading. The method further includes digitally determining, the computing apparatus, whether the sensors are placed on the person according to a predetermined sensor arrangement based on both the first and second headings of each sensor; and adjusting, the computing apparatus, the operation of the motion tracking system based on the determination. Also, a system for tracking motion of a person.
