To walk down a busy sidewalk without bumping into people left and right, your visual system has to correctly chart a flurry of motion. It is no easy proposition, according to a Web tutorial that uses a series of animations to illustrate the challenges that the visual system faces to interpret moving objects in a way that makes sense.

The site, created by Fauzia Mosca and Nicola Bruno at the University of Trieste, Italy, acquaints upper level students with the problems of motion perception and includes Web animations such as the breathing square that reveal how the brain's motion sensors use information on time and space to overcome other limitations.
