The law of proximity states that single elements placed near or proximate to each other tend to be perceived as related elements. The explanation behind this principle is a cognitive tendency of the human brain to automatically organizes the elements, creating groups with those near each other.
This principle works for both Product Design and Communication Design to define a connection between different elements. For example, it is possible to place different buttons near each other so that the user will perceive them as a single group of related actions.
