Document Summary
Movements that stabilize the eye when the head moves. It has to deal with this issue, we need stable vision, not blurry. Lock the fovea onto a moving object and track it as it moves. You cannot perform smooth pursuit without a moving stimulus. You need a visual stimulus on which to fixate: there is a lag of about 200 ms in the brains ability to process and re start smooth eye (cid:373)o(cid:448)e(cid:373)e(cid:374)ts. Ideal for high frequency head movements while walking and running. What do saccades accomplish: eye movements reveal a good deal about the strategies used to inspect a visual scene. Each scan reflects the current task: painting with man an family, this might be the pattern of eye movements you make.
