Persistence of vision
Persistence of vision is the phenomenon of the eye by which an afterimage is thought to persist for approximately one twenty-fifth of a second on the retina
There are a few kinds of they way they use Persistence of vision, one of them is called zoetrope which is:
A zoetrope is a device that produces the illusion of motion from a rapid succession of static pictures.
The zoetrope consists of a cylinder with slits cut vertically in the sides. On the inner surface of the cylinder is a band with images from a set of sequenced pictures. As the cylinder spins, the user looks through the slits at the pictures across. The scanning of the slits keeps the pictures from simply blurring together, and the user sees a rapid succession of images, producing the illusion of motion.
The second way of Persistence of vision is called Thaumoscope which is:
A thaumatrope is a toy that was popular in Victorian times. A disk or card with a picture on each side is attached to two pieces of string. When the strings are twirled quickly between the fingers the two pictures appear to combine into a single image due topersistence of vision.
The first use of the thaumatrope was used in the year 1824 when it is a spinning coin which tricks your brain to look that images are moving back and forth, it is used as one example of the early animations when they did not have software to make these sort of animations which is used to this current date with such use of programs such as Adobe Flash which you can create flash animations with to an extent which would be more present rather then making one of these Thaumoscope animations
