Calibration of inertial measurement units attached to arms of a user to generate inputs for computer systems

摘要: A system including: a sensor module having an inertial measurement unit and attached to arm of user. The is initially calibrated measure its orientation relative initial reference pose. To recalibrate the module, user moved obtain at calibration pose in horizontal plan both Preferably, arms are straight plane; hands meet each other may have twisted around from time recalibration. twist computed for
