People often say that 'seeing is believing', in fact, seen by the fact that the human eye is not completely reliable because the illusion. We do design, often encounter two different icon within the same interface design, length and width are equally large, but will find a larger or a smaller visual experience. This is the vision on human visual difference between subjective feelings caused; another case two elements are identical, because the impact on Air Max 2012 Green Orange Black the environment, feelings will be different. In fact, these are the optical illusion phenomenon. Optical illusion refers to feelings and objective reality, as the inconsistencies, referred illusion. People observe objects, since the object is disturbed shape, light, color, coupled with people's own physiological and psychological factors, will produce inconsistent with the actual determination of the visual error. In people's daily lives, optical illusion phenomenon is everywhere. For example, chopsticks into a bowl of water, due to the light refraction, looks chopsticks fold; body fat clothes to wear stripes appear more fat, lean body wear clothes bars look thinner, etc. These are the actual inconsistent optical illusion phenomenon. Optical illusion illusion can be divided roughly into two categories illusion shape and color. Shaped illusion are: length, size, distance, height, afterimage, hallucinations, split, column ratio. Color illusion are: light infiltration, distance, temperature, weight and so 2015 Nike Free 5.0 on. In this paper, to share some optical illusion in art, design, painting examples, so in-depth understanding optical illusion phenomenon funny side. 1. The illusion of impossible triangle shaped more abundant in the hands of graphic designers in the eyes of the designer changes the optical illusion of the world a typical optical illusion in LOGO design using a tape Nike Air Jordan 4 Women creation of street Nike Zoom KD V art, Air Max 2011 Womens Wine Red White Grey simple but colored lines a direct impact 616116-991 Red Black Nike LeBron X PS Elite Online on physical light stimulus to create stunning optical illusion effect 2. illusion color color directly from the psychological effects of color on human physiology occurred. Psychologists have done a lot of experiments. They found that, in the red environment, people will speed Nike Air Max up the pulse, blood pressure was increased, emotional excitement impulse. And in the blue environment, the pulse will slow, emotions are more quiet. A lot of color theory are made for this special presentation, these experiences to us clearly affirmed the influence of color on human psychology. Cool and warm psychological illusion is based on the physical properties of color classification, the color of the impression material, generally produced by New Nike Tr Fit Running Shoes Black the well-being of two colors. Long-wavelength red and orange, yellow light, warm sense of itself, and therefore light shines on any color will have a warm feeling. On the contrary, the wave length of violet light, blue light, green light, there is a cold feeling. Above the well-being feeling, not from the real physical temperature, but our visual and mental association related. In everyday life, the green channel is often used in safety signs, the green traffic lights are allowed to pass. In interface design, the message class app Air Max 2012 Blue Grey White often used green as the main color, green has become a tacit sense of security in people's brain, felt personal information will not be leaked, therefore, it allows users to use such applications are not green independent New Nike Tr Fit Shoes Black Red association to secure thus assured. Summed up the law, we found that most of the product design use of color, from the people living in both color perception. Newsreader class more red, red gives a solemn, solemn and authoritative sense; life services more orange, the people need help, the orange sun gives warmth, but also can stimulate people's desire for Air Max 2012 Blue Silver White consumption; tourist class multi-use blue and green, giving free, fresh comfortable, casual feel. Remove to cool and warm temperatures outside of our different feeling, but also bring some other feelings, for example, a sense of weight, humidity and flu. For example, emphasis on warm, cold color cast light; there is a density of strong warm feeling, cool feeling there is thin; comparison of the two cool stronger sense of transparency, the Authentic Mens Basketball Shoes All Red Nike KD 7 Factory Outlet transparency is weak warm; cool look moist, warm look dry; cool feeling very far away, there are looming Nike Air Jordan 5 Women warm feeling. Generally, in a narrow space, if you want to make it Air Jordan Outlet spacious, bright and cold Air Max 2012 Blue Silver White tone should be used. The following give a simple example to illustrate the same foreground elements, attention background from left to right color brightness and hue change, different feelings gives the entire page. Because the prospect of a crowded arrangement of elements, fills the entire screen, so with almost no breathing room for a black background, and very depressed; red background brightness have strengthened, but red too impetuous, or give full and many people feel; and blue Compared with the color red from some psychological feelings would comfort; the last one adopted smarter, cool color background sense of space than the left one and left with 2 twin lot better, the entire page clear up feeling icon also have breathing space. This simple example corroborated mentioned above, the effects of cold tones generated during use of the narrow space. In product design, the use of some simple and effective way, the problem will solve a lot of interface problems. In short, when we look at an object, when the wrong judgment and perception based on empirical or improper reference to the formation of our eyes in these specific conditions will indeed deceive ourselves, to understand and master certain optical illusion principle, will our future Design has a multiplier effect. As long as theory plus practice, I believe some of the methodology will indeed help to us.your eyes deceive you
