Gestalt Principles Guide

Introduction

The Gestalt principles of perception are a set of theories developed by German psychologists in the early 20th century. They describe how humans naturally organize visual elements into unified wholes, rather than perceiving them as isolated parts. The core idea is that "the whole is greater than the sum of its parts." Our brains actively seek patterns and structures to make sense of the world around us.

1. Proximity

Elements that are close to each other tend to be perceived as a group. Our minds naturally connect objects that are physically near one another, even if they are otherwise dissimilar.

Observe how changing the spacing of dots affects how you group them.

2. Similarity

Elements that share similar visual characteristics (like color, shape, size, or orientation) are perceived as belonging together, even if they are not close to each other.

Interactive Similarity Demo

See how elements with shared attributes are grouped.

3. Continuity

Elements arranged on a line or curve are perceived as more related than elements not on the line or curve. Our eyes tend to follow the smoothest path when viewing lines, even if they are interrupted.

Interactive Continuity Demo

Observe how lines are perceived as continuous even when crossed.

4. Closure

Our brains tend to perceive incomplete figures as complete. We fill in the missing information to create a whole, recognizable shape or object.

5. Figure-Ground

This principle describes our ability to separate elements from their background. We perceive some elements as the "figure" (the focal point) and others as the "ground" (the background). This perception can sometimes be ambiguous, leading to optical illusions.

6. Common Fate

Elements that move in the same direction or at the same speed are perceived as belonging together. This principle is particularly strong because motion is a powerful cue for grouping.

7. Symmetry

Symmetrical elements are perceived as a coherent group or a single object. Our brains prefer symmetrical arrangements and tend to interpret complex shapes as symmetrical if possible.
