In specific cases seeing the movement of our body and limbs as a 3rd person, can be useful in many aspects. Observing ourselves performing a technical sport can be rewarding and progressing. This way it becomes possible to fix incorrectly performed movements and lower the risk of injury.

The topic of my paper is the design and construction of a sensor based wireless network, processing the raw data and represent movement of the observed body. These sensors are attached to limbs and torso. Each sensor measures the angular rate, acceleration and the surrounding magnetic field using 3-axis accelerometer, gyroscope and magnetometer. The algorithm that fuses these measurements runs on a microcontroller, which then reports the processed orientation data to the central unit, using radio modules. The central unit is small enough to be worn on torso. This unit collects measurements of peripheral units and sends them to the display unit, using WIFI interface with MQTT communication protocol. The display unit runs Unity3D game engine, which displays the received data on a humanoid model in real time.
