一种先前用于探索生物运动的潜在刺激结构的技术是将玻璃头反光带附着在人的关节上，将强光聚焦在他们身上，然后用视频记录他们的运动。图像的对比度被调高，亮度被调低，这样就只看到一个移动的光点系统。这项技术很重要，因为它剥夺了可以用于识别的熟悉线索的刺激，但对感知的效力几乎没有影响。观众看到了展示的无形不变关系，这很容易被解释为一个运动中的人物。通过计算机步态合成的同步研究，推进了步态感知的研究。
One technique previously used to explore the underlying stimulus structure of biological motion attaches glass-bead retroreflectant tape to the joints of humans, focuses bright lights on them and video records their movements. The contrast of the image is turned up and the brightness down so that only a system of moving point-lights is seen. The technique in important because it deprives the stimulus of familiarity cues that could be used for recognition, but does little to the potency of the percept. The viewer sees the formless invariant relations of the display, which are readily interpretable as a human figure in motion. The study of gait perception was advanced through the simultaneous study of gait synthesis using a computer.
