Abstract

Motion capture (MoCap) systems are increasingly used for rehabilitation and diagnostic purposes. However, dissemination of this type of solutions requires further development and reduction of prices, especially for high-precision systems. The paper presents a tested MoCap system architecture, which is based on independent, integrated sensor modules. Some of the cheapest Wi-Fi 2.4 GHz transceivers with a SoC chip were used to build individual modules. This concept made it possible to obtain one of the smallest MoCap modules with a Wi-Fi interface. In turn, the implemented embedded software with an adaptive radio transmission control algorithm allows for optimization of the sensor module operation. The algorithm presented in the paper reduces both the transmission in the sensor network (by about 26%) as well as the router processor load (by about 80%).
