High-Fidelity Simulation of Human Muscles and Movement

Physics-based computer animation has improved our ability to simulate natural phenomena such as colliding objects, splashing waves, and moving characters. Although these simulation techniques can create compelling special effects for movies and games, the practical use of computer simulation in product design, ergonomics, and medicine remains very limited. In order for simulations to have significant impact beyond animation, they must not only be visually appealing, but also physically accurate and evaluated with experimental data. The proposed research program seeks to improve and evaluate the physical accuracy of human body simulations for applications in biomechanics. Our results will overcome the current limitations of human body simulation and improve our ability to diagnose movement disorders, guide rehabilitation, and train athletes.
