IMU based human movement tracking

The paper describes an inertial measurement unit based wearable, rehabilitation movement tracking device, which can be used for human hand movement tracking. Tracking the hand movements of the patient during rehabilitation and tremor assessment is a difficult but very important task. Our realized hardware employs a multi-sensor fusion based solution, where the data is taken from multiple axis accelerometer and gyroscope sensor devices. Multiple movement tracking sensor devices can be combined together and the data can be transferred wirelessly into a central DAQ device. The setup is able to provide real-time measurements and it is under testing in various environments. The paper describes the results of our hardware development with the description of its main functionalities.
