Virtual reality (VR) technology is every day becoming a more popular application for physical rehabilitation and motor control research. The goal of this project is to help with the rehabilitation of patients with injuries that affect their mobility or people with movement disability, remotely. There are studies that show that the visualisation of our own movements in an augmented way, nourishes our brain positively and accelerates the recovery. This Kinect-based rehabilitation application consists in accessing the Kinect body joints orientations defined with quaternion and apply them, through a code in Visual Studio (VS), to our avatar in Unity. Kinect is our input that captures the trajectories of skeleton points. Those data are received in Unity, a game development engine. We then wrote a code in VS to process those data and, once the joint orientations were processed, we were able to apply them into an avatar in Unity so that it reproduces our movements in real-time. The project opens a door to a wide variety of future medical applications since a full human body is tracked and can help with any possible avant-garde rehabilitation techniques.
