Motion capture systems are becoming more and more important tools serving in the process of calculation, design process as well as evaluating the performance of the rehabilitation equipments. In addition, it is also a common device used in the performance evaluation of rehabilitation process during exercise stages. In this article, a cheap motion capture system measured 7 Degree of Freedom (DOF) of upper limb will be presented. It is an improvement from an earlier portable measuring device made of plastic material with 3D printing technology. The new, static device, constructed of aluminum, has proven to be more accurate than the previous one. After that, the study performed measurement experiments for some basic movements in daily living. In each movement, the study obtained 3 results including: the angles of the rotation angles of the measuring device, the trajectories of the end effector of the wrist joint, and the angle of the human arm joints.
