This paper presents a comparison of different configurationsof a wireless sensor system for capturing human motion.The systems consist of sensor elements which wirelesslytransfers motion data to a receiver element. The sensorelements consist of a microcontroller, accelerometer(s) anda radio transceiver. The receiver element consists of a radioreceiver connected through a microcontroller to a computerfor real time sound synthesis. The wireless transmission between the sensor elements and the receiver element is basedon the low rate IEEE 802.15.4/ZigBee standard.A configuration with several accelerometers connected bywire to a wireless sensor element is compared to using multiple wireless sensor elements with only one accelerometer ineach. The study shows that it would be feasable to connect5-6 accelerometers in the given setups.Sensor data processing can be done in either the receiverelement or in the sensor element. For various reasons it canbe reasonable to implement some sensor data processing inthe sensor element. The paper also looks at how much timethat typically would be needed for a simple pre-processingtask.
