What is Law of Similarity?
The law of similarity states, ‘The human eye perceives similar elements in a design as a complete picture, shape, or group, even when those elements are separated.’ The law ensures that links and navigation systems are visually distinct from normal text elements.
The law of similarity is the unconscious process of grouping sensory information with similar characteristics. Color, shape and size, orientation, and motion can indicate that elements belong to the same group and possibly share a common meaning or functionality.
Elements that are visually similar will be considered related.
Although this process occurs with visual and auditory information, the law of similarity usually refers to the visual stimulus. A characteristic shared in an image may be color, size, shape, brightness, or any other visual similarity that separates things into two or more groups.
