A motion sensing game bracelet system based on motion template feature matching comprises a power source module, an AGM sensor module, a processor module, a communication module and electronic equipment, wherein the AGM sensor module, the processor module, the communication module and the electronic equipment are connected in sequence. The power source module supplies power to the AGM sensor module, the processor module and the communication module, the AGM sensor module monitors the real-time motion state of an operator and collects motion and electronic equipment information, and the processor module receives and stores motion data transmitted by the AGM sensor module, analyzes and processes the motion data to obtain a motion feature parameter set, matches the motion feature parameter set with a motion template feature library to generate a corresponding game instruction and transmits the game instruction to the electronic equipment through the communication module. Complex motion and combined motion can be recognized, the energy consumption and calculation defects of a processor chip of the motion sensing game bracelet are overcome, the type of motion sensing games is effectively broadened, the difficulty of the motion sensing games is effectively improved, and player experience is improved.
