1. An identification method, applicable to a wireless motion capturing system with a plurality of wearable devices, comprising:
receiving sensor data, wherein the sensor data is associated with a motion feature, and the motion feature corresponds to a plurality of nodes of a virtual avatar model, wherein the motion feature corresponds to a hand movement of the virtual avatar model, wherein the plurality of nodes comprising at least one left hand node and at least one right hand node, wherein the sensor data comprising a first pose signal corresponding to the hand movement; and
analyzing the sensor data and identifying at least one of the plurality of nodes corresponding to each of the plurality of wearable devices, further comprising:
collecting a gyroscope signal accumulation value, a gyroscope signal maximum value, and a gyroscope signal minimum value from that first pose signal;
in response to the gyroscope signal accumulation value being greater than a first threshold and the gyroscope signal maximum value being greater than a signal threshold, determining the wearable devices as the at least one left hand node; and
in response to the gyroscope signal accumulation value being greater than the first threshold and the absolute value of the gyroscope signal minimum value being greater than the signal threshold, determining the wearable devices as the at least one right hand node.
