Embodiment Construction
[0183] The core point of the present invention is to use a built-in acceleration sensor and an orientation sensor for a sports or mobile device, and obtain the trajectory or path of the motion or mobile device by processing the acceleration sensing signal and the orientation sensing signal through an information processor. Due to the accumulative effect of the error caused by the measurement error of the acceleration sensor and the orientation sensor and the calculation error of the information processor, the calculated motion trajectory or path deviation is too large. The position information of the reference position is added as the reference information of the calculated motion trajectory or path. Correction of calculation results. In order to achieve this goal, it is necessary to add a reference device at the reference position, and transmit the position information of the reference position to the motion or mobile device to participate in the calculation of the motion trac...
