Explanation of Cognitive illusions and its phenomenon and use of flat optics
Explanation of Cognitive illusions and its application:
Depth and motion perception- Illusions basically depend on an individual’s ability to observe and see in three dimensions even though the image captured by the retina is a two-dimensional image. One of the most famous examples of an illusion is the Ponzo illusion which takes advantage of monocular cues of depth perception to fool the human eyes. The brain exaggerates the vertical distance compared to the horizontal distance even with two-dimensional images, as in the vertical-horizontal illusion where two lines are exactly the same length. The falt optics manufactured by the spherical lens manufacturer is also used to create cognitive illlusions, to know more about these optics visit website.
The brain is said to believe by the parallel lines that are converging that the image that is higher in the visual field is farther away in the Ponzo illusion, therefore, the image takes up the image to be larger but in reality, both the images that are captured by the retina are of the same size. Optical illusions are observed in a false/diorama perspective, also exploiting perceptions based on monocular cues of depth perception. Waterfall painting of the Dutch artist MC Escher exploits the depth and proximity laws and concepts understood about the physical world to create the illusion. The credit for the number of sensory illusions goes to depth perception, similar to motion perception.
Illusion in Film animation
This illusion is also used to create the film animation. In this illusion, the human brain captures a series of slightly varied images produced in rapid succession as a moving picture. Similarly, when we move or ride in a vehicle, the stable or stationary objects around us appear to be moving. We can also see that a larger object, like an airplane, moves more slowly than smaller objects, such as a car, although the larger object is actually moving faster. Another example of how a human brain captures and perceives motion is the phi phenomenon, which is most often created by blinking lights in close succession.
Due to the lack of visual references, there happens uncertainty in the direction of motion for depth can be observed in the spinning dancer illusion. It appears the dancer who is spinning is moving counterclockwise or clockwise depending on spontaneous activity in the brain where perception is subjective. Recent studies on fMRI suggest that this illusion is characterized by spontaneous fluctuations in cortical activity, particularly the parietal lobe as it is involved in the perceiving movement.
