  abstract  = {Motion-capture-based biomechanical simulation is a non-invasive analysis
              method that yields a rich description of posture, joint, and muscle
              activity in human movement. The method is presently gaining ground
              in sports, medicine, and industrial ergonomics, but it also bears
              great potential for studies in HCI where the physical ergonomics
              of a design is important. To make the method more broadly accessible,
              we study its predictive validity for movements and users typical
              to studies in HCI. We discuss the sources of error in biomechanical
              simulation and present results from two validation studies conducted
              with a state-of-the-art system. Study I tested aimed movements ranging
              from multitouch gestures to dancing, finding out that the critical
              limiting factor is the size of movement. Study II compared muscle
              activation predictions to surface-EMG recordings in a 3D pointing
              task. The data shows medium-to-high validity that is, however, constrained
              by some characteristics of the movement and the user. We draw concrete
              recommendations to practitioners and discuss challenges to developing
              the method further.},
