How to keep from stumbling on steps...
Elliott et al. make the neat observation that a simple visual illusion can lead to safer stepping behavior. The perceived height of a step is manipulated as shown in this figure:
Subjects perceived the step to be higher in the V (vertical stripes on the height dimension) configuration on the right compared to the H (horizontal stripes) configuration on the left, and correspondingly raised their toes higher to clear the step.

I've tried, but I can't see a V or an H?
ReplyDeleteV and H refer to vertical and horizontal stripes.
