What is visual illusion? The visual illusion is the wrong judgment and perception based on empirical or inappropriate reference. For example, the French flag red, white, blue tricolor ratio of 35:33:37, and we feel the three color area equal. This is because white gives people the feeling of expansion, while blue has a sense of contraction, which is the visual illusion.

　　Often used in the design of visual illusion, visual illusion can effectively improve the use of space, design aesthetics and visual effects. Some illusions can be corrected, but some are inevitable. In interior design, we want to use, is the inevitable part. So how to use the visual illusion in the design?

　　Low see high is the most commonly used in interior design of an optical illusion treatment

　　1, high in the high. This is the most commonly used in interior design of a visual illusion treatment. Method is the room in the common space, one part of the ceiling, and the other part does not do, then there is no ceiling part will become "high".

　　2, virtual reality. Through the bar or the whole glass mirror, can create a virtual space in a real space inside, and the deficiency in visual space, but the space. This kind of visual illusion, is also commonly used in interior designers.

　　3, cool cool. This, in essence, belongs to the chapter of color psychology, but also a way to use the principle of visual illusion. For example, when we use a large number of days in the kitchen dark, then we stay inside, it will feel the temperature dropped 2-3 degrees (feel, non scientific data).

　　Seeing the illusion of straight formation in coarse and fine medium

　　4, coarse and fine. In the wood floor tiles or other finish high material side, placed some rough material, such as retro brick and stone, so smooth texture will be more smooth so. This is the contrast of the formation of visual illusion.

　　5, the song see straight. In some buildings ceiling treatment, often not flat, when the bending is not a lot of circumstances, then you can deal with the four sides near the flat right angle, resulting in visual overall flatness.

　　In interior design, we have a lot of time may be in order to produce special or better effect, also can be in order to improve some defects and the use of visual illusion, but note that the use of visual illusion, not a lot of flooding, excessive use of visual illusion, can cause visual hallucinations. Visual illusion is the visual basis of the fact that there is no reality, it is an unhealthy visual state.

　　Avoid excessive use of visual illusion will cause visual hallucinations

　　For example, we use a lot of mirror in the bedroom, there is a mirror of the wall, the wall is a mirror, the mirror is divided into blocks of all shapes and sizes, so much the illusion, the correct judgment will distort human, even thought it was fake, but cannot identify the false is true. The illusion, sustained healthy human eyes, long stay in this excessive visual hallucinations, can cause health problems, it is worthy of note.

　　Also because of this reason, in the interior design, the use of visual illusion, dealing with using correctly explain, to let people know you are treated, and they know and can not influence the perceived enjoyment, a key problem is that the use of visual illusion. For example, we manufacture the virtual space in front of the mirror, a vertical or horizontal wood to be cut, it can greatly reduce the visual distortion.
