Summary: 
Most researches on animacy perception have not addressed whether we perceive animacy or not from the movement of a structural object. We thus focused on two-link mechanism, as the simplest mechanism of structural objects, and experimentally tested whether observers perceived animacy or not from open-close movement of a two-link rigid arm. We also specified the important physical quantities of movement from which they clearly perceived animacy. As results, we found that observers perceived animacy from the movements that had almost the same physical quantities as the movements of real creatures did, such as human walking and birds' flapping their wings.
