A Low-cost Serious Game Therapy Environment with Inverse Kinematic Feedback for Children Having Physical Disability

Recently, the use of non-invasive ways to track joint motion in the human body has drawn significant attention in the therapy domain. One of the reasons for this popularity is due to availability of economically priced 3D motion sensors. In this paper, we present a web-based 3D interactive serious game interface that uses non-invasive methods to recognize the movements of the body. Motion data of a subject is collected through two motion sensors, a Kinect and a LEAP, in a non-invasive manner. Joint motion along with inverse kinematic joint information is displayed in 3D environment in a live manner or recorded for offline replaying and data analysis. To facilitate the complex therapy authoring process, the system incorporates an authoring tool that allows a therapist to design a complex therapy in terms of primitive therapies and assign it to a patient. The subject as well as other members of the community of interest such as therapists, parents and caregivers can view the results at any time and can follow up with patient's progress.
