Optical Illusions - Screen Lock.
Optical illusions change your perception of the world, on the one hand it is a normal image, and from another animation. Why is this happening? It will remain a mystery to us. However, they will diversify your unlocking screen, and the app will be useful and easy to use!
On these images you will see something that is really hard to imagine. Illusions often lead to an incorrect quantification of real geometric quantities. Inadequate perception of an element and its properties. The most studied are the illusions that arise when the visual perception of two-dimensional contour images. The brain unknowingly sees drawings only in a single-convex (single). Perception depends on the direction of outdoor lighting. Limit values of real values depend very much on the nature of the background image. This applies to lengths, squares, curvature radii, angles, shapes, etc. The illusion of motion is when the static and stationary pattern "comes alive" and starts to move, or begins to turn into one, and then to the other side. There are drawings that are throbbing, although in reality - all these are static drawings. The basis of these optical illusions lies in the fact that the objects have the same lighting, but so depicted that the brain "thinks" that they have different shades, colors, etc.
Optical illusions, or as they are also called optical deceptions, occur in healthy people relatively often throughout life, since they are completely normal, depending on the specific conditions or structure of the human eye. The causes of some illusions are established, but most of them have no scientific explanation, and to this day. By known types of optical illusions are the phenomena due to the peculiarities of the structure of the organ of vision - it irradiation, deceit of vision, the associated astigmatism.
