Summary:
- The human visual system has a limit to how fast it can process information. This study found that the maximum speed at which people can accurately detect visual changes is around 47 milliseconds.
- This means that our eyes and brain can only process visual information that changes at a rate slower than 47 milliseconds per change. Anything faster than that becomes too blurry or difficult for our visual system to perceive.
- This "visual speed limit" helps explain why we can't see individual frames in a movie or video game, even though they are changing at a rate of 24-60 frames per second. Our visual system blends those rapid changes into a smooth, continuous image.
