在视力正常和视力受损的步行者中，以三种不同的步速测量步长和步频的变异性。变异性较低，尤其是在首选起搏下，两组相似。结合步数和步频的模型提供了对行进距离的良好估计。应用寻路技术进行了讨论。
The variability of the length and frequency of steps was measured in sighted and visually impaired walkers at three different paces. The variability was low, especially at the preferred pace, and similar for both groups. A model incorporating step counts and step frequency provides good estimates of the distance traveled. Applications to wayfinding technology are discussed.
