Gestalt Principles of Organisation

Principle of Proximity

Objects close together will be grouped together

Principle of Figure-Ground

We prioritise certain information over the background

Principle of Similarity

Objects that look similar tend to be grouped together

Principle of Closure 

We tend to percieve whole objects even when part of it is missing 

Principle of Good Continuation

Even when lines are crossed or interrupted we tend to percieve them as continuous anyway

Principle of Common Fate

Objects that are moving together will be grouped together
