An optical illusion called the effects of visual perception that occur involuntarily or deliberately, the person watching specific images.
These effects are also called optical illusions, errors of visual perception, which are caused by the inaccuracy or inadequacy of the processes occurring at the unconscious correction of visual images. In addition, the process of the emergence of optical illusions are also involved physiological characteristics of the organs of vision and the psychological aspects of visual perception.
The illusion presented in this app is the distortion of perception by a wrong evaluation of the lengths of segments, angles, colors, visible object etc. Its most popular types include the illusion of depth perception, shape-shifters, stereo-pairs and the illusion of movement. The illusions of depth perception refers to the inadequate reflection of the subject depicted. The most known examples of such illusions are two-dimensional contour image – when observed, they are unconsciously perceived by the brain as adenovirally. In addition, distortion in depth perception can lead to incorrect evaluation of the geometrical sizes (in some cases, the error reaches 25%).
The illusion the shifter is in the image such images, the perception of which depends on the direction of gaze.
Stereo pair make it possible to observe a stereoscopic image by superimposing them on the periodic structure. The focus sight behind the picture leads to the observation of the stereoscopic effect.
Moving illusions represent periodic image, long look at that leads to visual perception of movements of the individual parts.
