The Law of Continuity, also known as the Principle of Continuity, is one of the Gestalt laws of perceptual organization. It refers to the way our mind experiences visual line of elements as being continuous, even if they are not. Essentially, this law suggests that elements arranged on a line or curve are perceived as more related than elements not on the line or curve.

According to this principle, when we perceive a sequence of objects or shapes, we are likely to construct a mental continuous line or pattern, which helps in simplifying and organizing our visual perception. This happens because our minds tend to follow along paths and favor continuous figures over disconnected ones.

For instance, if there are dots aligned in a way that they form a wave or a smooth curve, we are more likely to perceive them as part of a wavy line rather than as individual, unrelated dots. This applies to a variety of visual elements, including lines, edges, curves, and a series of points.

The Law of Continuity plays a crucial role in areas like design, art, and architecture. In user interface (UI) design, for example, it helps in guiding the viewer’s eye movement and can influence the way information is organized and presented for better understanding and aesthetic appeal. By understanding and applying this principle, designers can create more intuitive and visually appealing designs that align with the natural human tendency to seek continuity in visual elements.
