A travel path may be firm or soft, slippery or sticky, and will thus affect locomotion. In humans, associations are made between various travel surfaces and gait modification. If a preferred foot position is unavailable, an alternate is selected. This selection is biased, and not random. Here we present a model of alternate foot placement. We demonstrate some novel properties of the model, thus showing its predictive value. We give results in a small bipedal walking mechanism. The power of our approach is that it captures key features of human performance and can be easily implemented in most walking machines.<\/jats:p>","DOI":"10.1177\/0278364905055419","type":"journal-article","created":{"date-parts":[[2005,7,5]],"date-time":"2005-07-05T05:50:42Z","timestamp":1120542642000},"page":"553-561","source":"Crossref","is-referenced-by-count":4,"title":["Foot Placement Selection Using Non-geometric Visual Properties"],"prefix":"10.1177","volume":"24","author":[{"given":"M.
