Regarding Camouflage, Humand Perception and Ghillie Suit:
The perception of objects and shapes is determinated by the mental organization of environment elements, employed by the brain.
The human brain is led to perceive shapes and figures in contrast with the background, due to an automatic, innate mechanism that defines the laws of human perception. The Ghillie Suit works extremely well in natural environments, as it breaks the human shape and interferes with the innate perception mechanism of environment reconstruction.
The Ghillie Suit's effectiveness can be scientifically explained by Gestalt, one of the major schools and approaches of experimental Psychology. Gestaltists postulate that perception is the product of complex interactions among various stimuli through which the mind creates a self-organized "Global Whole". This self-organized "Global Whole" is affected by several specific laws of human perception, that can help explain why and how Ghillie Suits work. It is worth mentioning the fundamental principle of Gestalt perception:
- Law of Emergence: also known as the Law of Prägnanz or Law of Good Gestalt, it states that perception of an object from the background depends on its relevance, namely, the contrast between the objects and the background. When contrast is minimal the figure does not emerge from the background- this is the first variable of camouflage. Using a Ghillie with the same colouring as the surrounding environment thus significantly reduces emergence, increasing camouflage, as the object is perceived as a part of a whole, at one with the environment.
