What does the term "persistence of vision" refer to in design?

The term "persistence of vision" refers to the optical phenomenon where the brain retains an image for a brief period after it has disappeared from view. This principle is foundational in visual media and design, as it explains how a sequence of rapidly shown images can create the perception of smooth motion, as seen in animations and films. When frames are displayed in quick succession, the brain blends them together, leading to the illusion of continuous movement.

This concept is crucial for graphic designers and animators because it directly impacts how they create and present visual narratives. Understanding persistence of vision helps designers decide on frame rates and transitions, ensuring that the audience experiences a seamless visual flow. This is particularly important in mediums such as animation, where the effectiveness of designed sequences heavily relies on the viewer's perception of motion.
