Optical Illusion Resulting from The Use of Reflective Surfaces and The Importance of Applying it in Various Interior Spaces

Optical illusions in interior design are one of the subjects that deserves study, it is a design solution to many problems related to space elements and has an effect on the shape and space in the various interior spaces. There are many types of optical illusions by shape, color, and material, as, for example, the use of reflective surfaces in interior spaces that may lead to a change in the perception of size, lighting, colors, as well as the location of furniture pieces, because of the effect of the reflection, such as the illusory feeling of extra space or increase in depth or height. Therefore, the reflective surfaces are an important type of optical illusion, where the reflections of mirrors change the relationships between the elements of space and the pieces of furniture, which gives new and imaginary dimensions to the inner space.

This research discusses the possibility of achieving visual deception with materials or reflective surfaces with a view to applying them to an expansion of interior design and to benefit from their effect on the user within the space.

There are many different types of reflective surfaces that can be applied in interior design (either flat, concave, or convex) as each has a different effect on the shape of the space. Not only mirrors, but there are also many reflective materials that can be used in various space elements such as ceilings, floors, walls, and furniture, and each of them has an effect in achieving visual deception for users. So how far can the reflective surfaces add a false extra space to the inner space, and is it an appropriate solution to narrow spaces?
