Abstract: In some aspects, the disclosure is directed to methods and systems for body tracking systems and augmented reality interfaces. These systems provide an augmented reality application that enables a user to accurately perform physical therapy or training exercises at home and enable real time monitoring and communication between the user and a remote physician or trainer. Using motion tracking capabilities of depth cameras and/or multiple camera setups, the system can create a real time three dimensional model that mirrors or guides the patient's movements and can show the patient how to properly perform an exercise with dynamic interactive feedback. The tracking capabilities further provide physicians with detailed measurements as well as tracking improvements or degradations over time, and guide positions may be adjusted to provide further instruction or training as necessary.
