The Hub of Being (16-1-25) Motion Detection

 Motion Detection

To perceive motion is much more complicated than assembling a single image: detecting positional changes, and the velocities of objects, within the context of the scenery in its entirety, as well as accounting for movement by the perceiver. These differentials must be calculated within a small fraction a second – practically as fast as they occur. But the brain is overwhelmed handling fast-moving objects. So, a predictive algorithm is applied.

The object is not perceived in the position where the eye tells us it is. The object is shifted forward in the direction that it’s moving, predicting where things are going to be. ~ American psychologist Gerrit Maus
