You believe that you decide what you pay attention to. So much so that you never give it a second thought, but that’s only half the truth. There are principles that determine how people naturally perceive visual elements and you, as well as your users, are influenced by them.
When you understand the Gestalt principles, you know how to create a better UX. You design more user-friendly apps and direct the users’ attention to the right place and the important information. They look at what you want them to look at.
After reading this article you will realize that many apps are aware of these Gestalt laws, maybe — consciously or unconsciously — you are too. More importantly, you will be able to apply the Gestalt theory consciously and benefit from it.
What the Gestalt Principles Are
The Gestalt theory — that takes its name for the German word for form and shape — was founded by German psychologists in the 1920s. The Gestalt psychologists found out how people naturally organize, understand and perceive visual elements.
“The whole is something else than the sum of its parts.” — Kurt Koffka
The human mind — and therefore your user — sees the whole picture of the app before it recognizes specific elements. The Gestalt principles define and explain how the human mind perceives differently arranged elements.
Users becomes irritated and unfocused on the important elements when a certain design differs from their expectations. However, if you fulfill their natural expectations, you can draw the users’ attention to individual elements.
Why You Should Think About the Gestalt Principles
Choose the most effective design elements: Understanding the Gestalt laws — and therefore the human perception of thinking — will help you decide which design elements you should use in each situation.
Influence user behavior: You can influence visual perception. In doing so, you lead the users to specific points on your website or app.
Meet user needs: The principles will help you design websites and apps that meet the users’ needs. You can create a website or app that’s beautiful, intuitive and usable.
Gestalt Principles of Visual Perception
Law of Proximity
People tend to group together elements that are near each other. It doesn’t matter if these elements have different shapes, sizes or colors.
Proximity is more powerful than similarity or colors.
Watch the next picture. What are your first thoughts?
You probably think that there are three groups of circles: left, middle and right.
On second thought, you may identify two groups of light and dark blue circles. At first glance, the law of proximity dictates your interpretation.
How To Use the Law of Proximity
Bring elements that belong together closer together e.g., pictures with descriptions or buttons with texts. Use white spaces to show when elements are unrelated.
Be careful when putting elements close to each other when they don’t actually belong together. Users will automatically group them together.
Remember: Proximity is more powerful than similarity or colors.
Law of Closure
People have the tendency to literally try to see the whole picture. If there are any gaps in a figure, the human brain will still understand the bigger context by ignoring the gaps. These will be filled with information even if it isn’t actually there.
How To Use the Law of Closure
This law is often used to design icons. With its help, it’s possible to design simple icons and pictures. You can decrease the number of elements needed for the users to understand what you’re showing them.
Think about this law while designing your company or app logo. Be creative and see what works and what you like.
You should also keep this law in mind when you want to show elements with missing parts e.g., when you want your users to know that there is more if they scroll down a list. Whenever you show your users that the last element they see on the list is incomplete, they will understand that there are more elements coming.
Law of Similarity
Users understand elements that follow a similar pattern or look like they belong to a group.
Because of this law, it looks like there are four columns. If all the elements had the same shape and color, you wouldn’t think about four separate columns but rather a single group.
How To Use the Law of Similarity
Because users interpret similar looking objects as a group or a pattern, you can help them understand your website or app better.
Elements with the same meaning, function or hierarchy level should be designed in a similar fashion. Users will recognize the function of a given element and know that a similar looking one has a similar function, meaning or hierarchy level.
If you design two elements with the same functionality in different ways or design elements with different functionalities the same way, your users may get confused.
Law of Common Region
This law explains that elements that are put together in the same closed region will be understood as a group.
How To Use the Law of Common Region
Give related elements a frame to show that they belong together. If you define a clear border, you will be showing your users that the elements within it work as a group.
Cards are often used in UX design. Pictures, descriptions, prices or CTA buttons are placed within one closed region. Users understand the card and everything inside it as a separate entity from the card next to it.
Law of Continuity
Individual elements that are positioned in a continuous line or a soft curve seem more related to one another than elements that are positioned randomly or in a sharp curve.
How To Use the Law of Continuity
Paying attention to this law while designing your website or app will make your users look at the different elements of your product without thinking twice about it. Their eyes will automatically hover over the design and content.
Besides the lack of effort needed on their part, you can guide your users through the segments. When the continuity of the elements is disrupted, the users realize that a new segment has started. This helps them make their way through the different sections within your product.
Other examples of this on both apps and websites are user registrations and purchases. If the different steps towards these goals are put in order, users understand that they go together and need to be taken before they can complete the action. This way, it’s also easy for users to get an overview of what needs to happen.
Law of Figure and Ground
This law shows that people instinctively recognize if elements are in the foreground or background. Users also know that the foreground is more important than the background.
How To Use the Law of Figure and Ground
You can influence where users focus. By designing your website or app with an explicit foreground and background, you help your users decide where they should focus and what information is incidental.
You can combine beautiful background pictures with important elements like buttons and fields. Your users will recognize the beautiful design but still focus on the important elements.
Be careful though: Make sure that the foreground differs significantly from the background. Otherwise, it won’t work. If you use similar colors, the foreground gets less attention than if you use dissimilar ones.
Law of Symmetry
Symmetric elements give users the feeling that everything is organized, meaning that symmetry makes them feel comfortable with the design of your website or app. If the elements are asymmetrical, your users will waste a lot of time trying to find out the logic behind the asymmetry. They will be left feeling like something’s wrong, missing or out of balance.
How To Use the Law of Symmetry
You don’t have to try to design your product in complete symmetry. More often than not, this isn’t even possible.… And it would make your app or website look boring.
You have to find balance between symmetry and asymmetry. Don’t arrange the elements randomly.
Background pictures, matching colors and other elements will bring balance to your product design if used properly.
Asymmetric elements in a symmetric website or app can take your users’ attention to one specific point of your preference.
Law of Common Fate
The law of common fate says that elements that move in the same direction are more likely to be considered to belong together than those that move in opposite directions or don’t move at all.
How To Use the Law of Common Fate
Because of this law, users expect associated elements to move in the same direction, and vice versa.
This is why to get the most out of this law and fulfill the users’ expectations, you should ensure that the elements that belong together move in the same direction and at the same speed.
You can use this principle when designing drop-down menus or when illustrating a process like user registration. In those cases, the movement is implied through the process.
