The TI CC2540 processor handles the x-axis, y-axis, and z-axis data acquired by the LIS3DH sensor in real time and transfers it to the handset client APP(Application) via Bluetooth 4. 0 protocol for data processing and display to correct the posture of the human body purpose. And the system can be achieved with the organic combination of somatosensory games, to achieve the purpose of exercise.

Key words: somatosensory games, medical electronics, wearable equipment, LIS3DH sensor
