Abstract
In this paper, we present a serious game-based framework for providing live feedback to a patient performing a rehabilitation therapy for the purpose of assisting a patient in correct therapeutic steps and obtaining high quality therapy data for further analysis. The game environment uses forward kinematics to receive the live sensory data from two 3D motion tracking sensors and uses inverse kinematics to analyze the sensory data stream in real-time. A subject performs a rehabilitation therapy prescribed by the physician and using both forward and inverse kinematics the system validates the angular and rotational positions of the joints with respect to the correct therapeutic posture and provides live feedback to the subject. As a proof of concept, we have developed an open source web-based framework that can be easily adopted for in-home therapy, without the assistance of a therapist. Finally, we share our initial test result, which is encouraging.
