METHOD AND APPARATUS FOR POSITION AND MOTION INSTRUCTION

World data is established, including real-world position and/or real-world motion of an entity. Target data is established, including planned or ideal position and/or motion for the entity. Guide data is established, including information for guiding a person or other subject in bringing world data into match with target data. The guide data is outputted to the subject as virtual and/or augmented reality data. Evaluation data may be established, including a comparison of world data with target data. World data, target data, guide data, and/or evaluation data may be dynamically updated. Subjects may be instructed in positions and motions by using guide data to bring world data into match with target data, and by receiving evaluation data. Instruction includes physical therapy, sports, recreation, medical treatment, fabrication, diagnostics, repair of mechanical systems, etc.
