This sketch describes a novel insight for combining mocap with simulation in real-time. We demonstrate that promoting joint target angles to world space produces stable playback of motion capture in the presence of dynamic constraints and continuous physical simu- lation. We report that motor gains in world space are more stable and require less manual tuning than in parent space. Our approach also provides physically plausible motion blending due to simula- tion torque limits. We demonstrate a boxing video game, similar to [Zordan and Hodgins 2002], in which the fighters realistically stagger under the impact of attacks while performing captured ani- mations.
