The eye follows continuous lines and curves in preference to broken paths

The Gestalt law of continuity (continuation) states that the human eye follows the smoothest path through a design, preferring continuous flows over abrupt direction changes. Where two lines cross, we perceive two continuous curves rather than four separate segments meeting at a point. In motion design and generative visuals this means smooth arcs and gradients feel cohesive; sharp corners or discontinuous jumps read as separate elements. In typography, continuity explains why a column of text reads as a single entity even when individual letters and words have gaps between them.

Examples

Two curved lines that cross are perceived as two curves passing through each other, not four separate arcs. A horizontal navigation bar reads as a continuous ribbon even with gaps between items.

Assessment

Draw a design where two visual paths intersect and predict which path the viewer’s eye will follow. Then confirm by eye-tracking or informal user test.
