Motion sensing game,as a kind of novel game,is operated by body movements.It is respected by the majority of players of all ages because of its excellent interactivity.Currently,compared with the 2.4GHz wireless transmission technology that mostly used by motion sensing game controller,the Bluetooth 4.0 technology has the advantage of low power consumption,low cost and easy to connect to phone.So this technology has a bright application prospect in the motion sensing game controller.The paper introduces a kind of wireless transmission system with inertial sensor data based on Bluetooth 4.0 Technology which can be used in somatosensory gaming devices with the achievement of the accurate control of the game.This system includes three parts,which are data acquisition node,the wireless data transmission by Bluetooth 4.0 technology and PC upper monitor software that monitors data.
