A Kinect-based Tai Chi exercises evaluation system for physical rehabilitation

In this paper, we present a physical rehabilitation system which is based on Kinect sensor, to assist patients with movement disorders to perform “Tai Chi” exercises at home. By skeletal tracking of Kinect sensor, each movement of the patient is recognized and validated. Patient´s movements are compared to the prerecorded movements of coach, and further evaluated by using Fuzzy logic system. The experiment was carried out according to an ABAB sequence in which A represents the baseline and B represents intervention phases. Experimental results show that the participants significantly increased their motivation for physical rehabilitation, thus improving exercise performance during the intervention phases.
