Abstract
The present invention provides a real-time motion recognition method for identifying whether an inertia-sensing device is in active state or not according to an angular velocity signal detected with respect to the device. The present invention further provides an inertia-sensing and trajectory-reconstruction device incorporated with the foregoing method for recording detected acceleration and angular velocity signals while the device is in operation so as to reconstruct a corresponding trajectory which is capable of being subsequently utilized to be a basis of writing recognition and motion analysis.
