Motion sensing game is a novel game and operated by body segmental movements. It is respected by the majority of players of all ages because of its excellent interactivity. At present, many companies adopt the method of video capture to implement the collection of movement information, but the cost is much higher. And it also can achieve the accurate control of the game through the sensing technology of inertial sensor. This paper introduces a kind of wearable motion sensing game device presented in the form of glasses. Using a 9-axis sensor module determines the glasses posture, sequentially realizing real-time detection of the head movement. The inertial data is packaged and sent to the according base-station by the BLE4.0 wireless technology. The base-station contains an interface circuit of USART to USB and can transmit inertial data to the PC through this interface. Compared with using the RF module (e. g nrf24l01), the Bluetooth 4.0 technology has the advantage of low power consumption, low cost, small volume and easy to connect to phone. So this communication technology is suitable for the use in the motion sensing game controller.
