Laws of UX

Discover the essential Laws of UX that guide user experience design. Learn the principles to create intuitive, user-friendly, and effective digital products.

 

Law of Pragnanz:

when people are presented with complex shapes or a set of ambiguous elements, their brains

choose to interpret them in the easiest manner possible.

Human eyes like to find simplicity and order in complex shapes because it prevents us from

overwhelm and informative

Humans tend to find easy or meaningful in complex things

The human eye simplifies complex shapes by transforming them into a single unified shape.

Or we can say that people will perceive and interpret complex images in the simplest form possible because it is the interpretation that requires the least effort on the mind and this is why the law of pragnaz suggests that when people are presented with complex shapes their brains choose to interpret them into easiest manner possible. 

This law also refers to the law of good figure   

 

Law of Similarity :

Study shows that approximately 70% of individuals show a preference for group grouping similar shapes or colors whether it’s recognizing patterns in nature. 

This law plays an important role in shaping our perceptions and behavior    

Human eyes tend to perceive similar elements in a design as a complete picture, shape or

group, even if those elements are separated

Elements that are visually similar are perceived as related

Color, Shape and size orientation and movement can signal that an element belongs to the same

group and likely share common functionality.

Ensure that navigation and system are visually different from normal text and icon

(links should be diff from normal text).

This principle is a galed principle or we can say that how people visually perceive the world 

 

Halo Effect :

Overall positive impression of a person, product, or brand is based on a single characteristic.

It is a psychological phenomenon which is discovered in 1920 by Edward Thorndike. He said that when people have their first negative impression of something they carry that negative impression with them and apply it to other even unrelated aspects.

This law also has a positive impression means if we offer a positive first impression, people are more likely to carry that positivity through as they interact with the rest of our product   

 

Authority Bias:

It is a law which tells us that suppose there is a pair of shoes and one popular person is giving advertisement for those shoes. So when other people or common people see this advertisement then they also have some trust in those pair of shoes. Or we can say that Giving more weight to the opinions and actions of authority figures affects what choices people make and the way they now take this information in their everyday lives. This is called authority bias. Authority Bias is the tendency to give greater value to the opinion of an authority person rather then the actual value of the content and this opinion can be more influenced by their opinion.

Fitts Law :

Fitts’ law states that the amount of time required for a person to move a pointer (e.g., mouse

cursor) to a target area is a function of the distance to the target divided by the size of the

target. Thus, the longer the distance and the smaller the target’s size, the longer it takes.

A model that predicts how long it takes to move to a target area.

We can also say that The movement time taken by the target depends on the size of the target and the distance to the target.

Fitts’s law gives us the relationship between the time it takes a pointer (such as a mouse cursor, a human finger, or a hand) to move to a particular target.

 

Parkinson’s law :

Without proper time constraints, these feedback cycles can become unnecessarily lengthy,

leading to lesser productive returns.

Get the things easily rather than working for it.

any task will expand to fill the time allotted for completion.

(ex, using AI )

In other words, the more time we take to complete a task, the longer we will be engaged in that particular task. it will take us. But here’s the good news — this law can be applied to user experience design, and it can make a big difference in how people use websites and apps.

Position Principle (80/20 rule) :

the idea that 80% of outcomes are caused by 20% of inputs or effort.

Work for 20 the result will be 80

PININTREST for Laws

One way to be focused on any work is by using the 80/20 rule. The 80/20 rule, also known as the Pareto Principle, states that 80% of results in a system come from 20% of the work or causes. Its origins stem back to Vilfredo Pareto, an economist who noticed that 80% of Italy’s land was owned by 20% of the population. We have also seen, that the 80/20 way of thinking can provide proper and endless applicable analysis, including user experience strategy.
