Abstract: The aim of this study was to investigate the role of visual information in the control of walking over complex terrain with irregularly spaced obstacles. We developed an experimental paradigm to measure how far along the future path people need to see in order to maintain forward progress and avoid stepping on obstacles. Participants walked over an array of randomly distributed virtual obstacles that were projected onto the floor by an LCD projector while their movements were tracked by a full-body motion capt… Show more

“…1D). ‡ Indeed, restricting a walker's ability to see upcoming terrain to less than two step lengths results in decreases in stepping accuracy and walking speed (43). Furthermore, the trajectory of the COM is less like that of a passively moving inverted pendulum compared with when walkers can see two or more step lengths ahead, suggesting that walkers need at least two step lengths of visual lookahead to exploit their inverted pendulum dynamics when walking over complex terrain (44).…”

“…In a previous study with a similar experimental design, we found that some subjects accommodated smaller visibility windows by decreasing their walking speed and maintaining a low collision rate with the obstacles while others maintained a normal walking speed at the cost of increased collisions [43]. To encourage more homogeneous behaviour in this study, subjects were only allowed to hit one obstacle within each trial.…”

“…Virtual obstacles were displayed by a Sanyo PLC-XP45 projector at a resolution of 1024 Â 768 and a brightness of 3500 ANSI lumens. Details of the experimental set-up and the procedure to calibrate and synchronize the projector with the motion capture system can be found in [43].…”
