Development of Cost Effective Motion Capture System based on Arduino

In recent years, motion capture is predominantly used in biomedical and entertainment industry. The widespread use of motion capture in entertainment industry has deployed revolutionary changes in the field. At the same time, motion capture technology enhances the quality of human lives with its contribution to perform motion study in the applications like medical diagnosis and rehabilitation. Many research works have been carried out to make the technology as more accurate, versatile and viable to use in other fields. On the other hand, optical system also gains research interest with its extended applications in big industries and facilities. But they are very expensive and requires a large setup with various other limitations that makes optical system unaffordable for many small-scale industries and applications. This research work proposes a system based on inertial sensing is observed as a more accurate model when compared with the existing optical system and it also overcomes many other major drawbacks like flexibility and initial costing. System consists of MPU6050 integrated with Arduino Uno board. The output is serially given to computer via Arduino board, on which the output is presented in unity software. Complementary filter is used to integrate data from sensors.
