Enhance brain power using Optical and Visual Illusions

Visual illusions are visual perceptions of aim object which diverge from true characteristics of object, where brain observes object differently to state in which it really exists. Use of computers has brought about extraordinary progress in past twenty years.

Scope of visual illusion research is enormously different, ranging from studies of visual illusion of shape (geometrical illusion) to those of colour, completion, brightness, and depth. Huge body of knowledge therefore accumulate has potential for application in varied fields, as well as medicine, architecture, welfare, transportation and environmental design.

Optical illusion also known as a visual illusion is classified by visually alleged images which vary from objective reality. Information collected by an eye is process in brain to provide perception which doesn’t tally with physical measurement of stimulus source. There are three major kinds: literal optical illusions which create images which are different from objects which produce them, physiological ones which are the effects on eyes and brain of extreme stimulation of particular kind tilt, colour, brightness, size, position, movement, and cognitive illusions, the consequence of unconscious inferences

A famous artist Stotter's work takes benefits of fact which our eyes float and our brains be likely to jump to conclusions. Act of considering something starts with light rays bouncy off the object. These rays enter eyes through cornea that is the clear, outer portion of eye. Cornea then bends or refracts light rays as they walk off through black part of the eye, i.e. the pupil. Iris coloured portion of eye  contracts or expands to change amount of light which goes through.

At last, light rays go through lens of the eye that changes shape to target light towards the retina, the thin tissue at back of the eye which is full of nerve cells which detect light. Cells in a retina, known as rods and cones, turn light into electrical signals. That gets sent through optic nerve, where brain interprets them. Whole process takes about one-tenth of second, but that is long sufficient to make the brain confused sometimes, evolutionary neurobiologist Mark Changizi told Discovery News.

By arranging the series of patterns, images, and colours strategically, or playing with way the object is lit, brain can be tricked into seeing something that is not there. How you observe proportion can also be modified depending on known objects which are nearby. It is not magic, it is the optical illusion.

For instance, Changizi indicated that when we move and see at something, image turn out to be a blurry line in the vision. As the brains relate those blurred lines with motion, static pictures which feature fuzziness tend to look like they are moving at warp speed.

There is also Ebbinghaus illusion, or Titchener circles, that messes with how we evaluator size object. It is all relative. When two circles which are precisely same size are put next to each other, but one circle is encircled by larger circles and other one by smaller ones, circle encircled by larger spots likely to appear smaller than its complement.

On principle, Stotter's image is not traditional optical illusion. But it uses some of similar principles. By using paint, artist makes softer the harsh lines of a body and produces shadows by using light and dark colours next to each other.

It can be useful students in learning at schools, universities or at home. Several class lectures covering perception can be improved with the quick "break" from a theoretical discussion which takes "hands-on" approach with the in-class demonstration. After bringing in a concept and theories related to perception, from consumer behaviour and/or advertising perspective, perception relates directly to how individuals process information, and therefore in general meaning the individual assigns to stimulus. Sites given below can give some excellent examples of optical illusions and visual phenomenon. You will have to view them before using them in class.

Collection of visuals to use in exercise might be significant, if there are detailed applications students must relate to conversation of perception. For instance, if discussion associates to advertising and visuals used in advertising, visuals which use motion and/or colour might be more significant. If course associates to how individuals process information and grow knowledge, then instructor might wish to choose visuals which individuals see in a different way, and therefore overall impression and stimulus got varies for individuals. In end, these individuals have processed item in a different way, and have different knowledge base or perspective.
