A kind of inertial sensor data wireless transmission system which can be used in somatosensory gaming devices is introduced. This system is composed of three parts which includes data acquisition node

Bluetooth device and upper PC for monitoring data. System software uses interrupt mode to send and receive data and realtime process data. After testing

the results show that data packet and command can be transmitted wirelessly

stably and reliably between upper PC and node

collected inertial data can reflect moving attitude of limb

it can be applied to body feeling game controller.
