Animated progress bar subjectively speeds up loading
At the ACM conference on human factors in computer systems, experts from Carnegie Mellon University will present an interesting study that is devoted to a variety of visual illusions for computer interfaces.
For example, one of the illusions makes it possible to “speed up” the progress bar by about 10% with the help of rhythmic animation along the loading bar (see video ).
This refers to the reduction of subjective time. As experiments have shown, people watching such a progress bar say that the download was about 10.5% faster than those who watched the usual loading bar without animation.
Scientists have conducted experiments that confirmed that rhythmic stimulations can distort the perception of time in an observer ( PDF ). And although no concrete research in the field of computer interfaces has yet been carried out, some representatives of the IT industry have already begun to exploit this feature of human psychology. For example, the basic version of such a visual illusion is embedded in the interface of the Apple Mac OS X operating system.

Researchers at Carnegie Mellon University set the goal to find the most effective progress bar that would distort the user's subjective time as much as possible. They experimented with different acceleration and direction of the waves. It was found that the greatest effect is the acceleration of the waves from right to left. In this case, the progress bar with a duration of 16.75 seconds is perceived in time as the usual loading bar for 15 seconds. Mac OS also uses right-to-left direction, but without acceleration.
