摘要：

The basis of visually guided locomotion is the ambient optical flow. Because animals with frontal eyes can sample only a portion of the flow field, they must continuously scan in order to be aware of their surroundings. Such scanning introduces-additional transformations of the retinal image, apparently complicating the extraction from retinal flow of the information in optical flow. We conducted computer simulations of eye movement graphically. These simulations revealed that when gaze direction coincides with heading direction on curvilinear paths, velocity vectors in the image plane become linearized. Based on these simulations, we contend that heading direction is specified by the perpendicularly aligned vectors.
