Conclusion. Event Perception. : an event is defined as a change in both time and space. . Thus . far we have discussed how our visual system processes very simple static qualities of the environment such as color, distance, pattern, etc. But, the visual system was not designed just to encode and understand these static events, instead, and even more impressively, our visual system was designed to encode and understand the meaning of "events", changes that are dynamic, that visually unfold over time and space.
