Phi phenomenon

Remember those books of still images, known as flip books that you had as a child? When you rapidly flipped the pages, it appeared as if the still images were actually moving. This is a kind of optical illusion of sorts, and it's a good example of the phi phenomenon, a psychological term that describes the optical illusion of seeing a series of still images as moving.

Here's the most common example of this: When you go to a movie theater, you see a rapid succession of still frames that make up the whole movie. But it doesn't look to your eyes like the film reel is flipping through a bunch of frames. It looks like one complete image.

The discovery of the phi phenomenon is attributed to Max Wertheimer, a German psychologist who studied sensation and perception. To demonstrate how the phi phenomenon works, researchers projected a line on the left side of a projector, and then a line on the right side of the projector. They did this in rapid succession. When asked what they saw, people observing indicated that they saw one line moving back and forth.

Basically, Wertheimer argued our brain filled in the space between the two lines, making it seem like the line on the left was moving to the right, instead of the two stationary lines that were shown. The faster these two lines are shown in succession, the more our brain tricks our eyes into thinking it's one line moving back and forth.]]> 2018-01-08 16:15:20 UTC https://padlet.com/mcc17004607/8bultwo5ohrb/wish/219415893 Beta Movement kervinlabuguen https://padlet.com/mcc17004607/8bultwo5ohrb/wish/219416035 This was first described by Max Wertheirmer in 1912.
Beta movement is an optical illusion where a series of static images are displayed on a screen which then creates the illusion of smoothly flowing scene. This can occur when the frame rate is greater than 12fps]]> 2018-01-08 16:15:38 UTC https://padlet.com/mcc17004607/8bultwo5ohrb/wish/219416035 Persistence of Vision johnvanzcarillo https://padlet.com/mcc17004607/8bultwo5ohrb/wish/219418019


 Persistence of vision works because the human eye and brain can only process 10 to 12 separate images per second, retaining an image for up to a fifteenth of a second. If a subsequent image replaces it in this period of time it will create the illusion of continuity.
