The law of continuation, also known as the principle of good continuation, is an important concept in visual perception and design. It states that when lines intersect, the human eye tends to follow the smoothest, most continuous path. This principle can be applied to graphic design, where lines can be used to guide the viewer's gaze and create a sense of flow and direction in a design. Synonyms for the law of continuation might include principles of continuity, flow, and coherence. Other related concepts include the rule of proximity, which states that elements in close proximity to each other tend to be perceived as a group, and the law of similarity, which suggests that elements that share similar visual characteristics tend to be grouped together in the mind of the viewer.
