Using the motion-capture technique, actors perform while wearing suits that have sensors in strategically placed spots (i.e., at the joints). The recorded performance is later translated into animation by maintaining the key spatial and temporal relationships from the original to the animation. How is this technique related to the study of perception from biological motion?
