Optic Flow: Perceiving and Acting in a 3-D World

Perceiving path from optic flow.

We examined how people perceive their path of traveling from optic flow. Observers viewed displays simulating their traveling on a circular path over a textured ground, a random-dot ground, or a dynamic random-dot ground display in which dots were periodically redrawn to remove extended dot motion trajectories (flow lines) in the flow field. Five viewing conditions were tested in which the simu...

Editorial: Perceiving and Acting in the Real World: From Neural Activity to Behavior

The interaction between perception and action represents one of the pillars of human evolutionary success. Our interactions with the surrounding world involve a variety of behaviors, almost always including movements of the eyes and hands. Such actions rely on neural mechanisms that must process an enormous amount of information in order to generate appropriate motor commands. Yet, compared to ...
