First you will think that you are watching a simple combination of shapes and colors – but as the images roll on, you will notice how things get a fresh perspective. Everything changes in an amazing way. It’s no wonder that this optical illusion has been viewed by more than 4 million people.
From the scientific definition we find out that optical or visual illusion is the perception of an image resulting in erroneous estimation of reality, and when it comes to a false perception of an object, optical illusions may occur even in the presence of that object. Watching the red disc with the white dots that rotate on its surface, we have the impression that a uniform circular motion is happening, but in reality it is not so.
This illusion has been catalogued by the “Scientific American” as one of the best of the year 2014. For the first time it has been designed Arthur Shapiro and Alex Rose-Henig at the American University in the USA. The overall impression when watching the image is that of a circular motion; but in reality, the movement is perfectly linear. In other words, if the light changes, items which were seemingly rotating will create the impression of linear motion and vice versa.
There are lots of moving images that give a sense of optical illusion, and when we look, we are sure that we see something, when in fact things are different in reality. The detailed explanation helps us to understand perfectly how each point is moving in reality.
Many times we are tempted to look at the big picture, without giving too much attention to detail. Few of us are sufficiently focused on the illusion itself and we immediately discover what the actual rule of the moving objects is.
American writer and astronomer Phil Plait stated that for many illusions, there is a moment when the brain realizes what is happening in fact, and then the illusion breaks.
