Abstract : During locomotion, the entire optic array along the path of travel is continuously transformed. The nature of the transformations is informative about changes in altitude, speed, and imminence of contact with environmental surfaces. Some global optic-array variables are self scaled and some are environment scaled. By unlinking the two types of variables we have been able to empirically assess their relative usefulness for detecting change in altitude and speed. Determining the perceptual effectiveness of optical sources of information also tells us what the functional metrics are for detecting and guiding self motion. (Author)
