Abstract：In order to simplify the measurement process of range of motion (ROM) of human upper limbs, to improve measurement efficiency and accuracy, and to realize automatic measurement, a measurement method based on Kinect somatosensory interaction technology was proposed. The data of the upper limb joint positions of the subjects were captured by Kinect sensor and transferred to a computer. Then, the data were used to detect the distance between the motion plan of upper limbs and coronal plane (or sagittal plane, or axial plane) and to regulate the measurement. The ROM results were obtained automatically. The feedback information of ROM was showed on the somatosensory human machine interface in real time. An experiment was performed on 40 persons who were divided into 5 groups. According to the method of ttest, the |t| values of shoulder and elbow ROM measurement were 1.53 of shoulder abduction, 1.17 of shoulder adduction, 1.30 of shoulder flexion, 1.58 of shoulder stretch and 1.47 of elbow flexion respectively. All of them were under 2.776. There were no significant differences in measured data with the expected value, so the measurement accuracy was high.
