Hi friends!

I have recently made a Twitter thread and felt I had to share it with our community here :)

I must admit that I am lacking UI/UX skills. So I decided to improve a bit.

In the process I learned something useful that I want to share with you!

It's called: "The Laws of UX"

The Laws of UX

Fitts's Law:

The time to acquire a target is a function of the distance to and size of the target.

Meaning: make the most important objects more accessible

Hick’s Law:

The time it takes to make a decision increases with the number and complexity of choices.

Meaning: Simplify

Jakob's Law:

Users spend most of their time on other sites. This means that users prefer your site to work the same way as all the other sites they already know.

Meaning: don't reinvent the weel

Miller’s Law:

The average person can only keep 7 (plus or minus 2) items in their working memory.

Meaning: Don't bombard users with information!

Occam’s Razor:

A problem-solving principle that the simplest solution tends to be the right one. When presented with competing hypotheses to solve a problem, one should select the solution with the fewest assumptions.

Meaning: when in dilemma, choose the simplest choice

Tesler’s Law:

Also known as The Law of Conservation of Complexity, states that for any system there is a certain amount of complexity which cannot be reduced.

Meaning: Do not over-engineer or over-refactor

Von Restorff Effect:

Also known as The Isolation Effect, this effect predicts that when multiple similar objects are present, the one that differs from the rest is most likely to be remembered.

Meaning: contrast is useful!

Zeigarnik Effect:

People remember uncompleted or interrupted tasks better than completed tasks.

Meaning: don't be intrusive

Doherty Threshold:

Productivity soars when a computer and its users interact at a pace (<400ms) that ensures that neither has to wait on the other.

Meaning: performance matters!

Pareto Principle:

The Pareto principle states that, for many events, roughly 80% of the effects come from 20% of the causes.

Meaning: Deal with the most important parts first!

Serial Position Effect:

Users have a propensity to best remember the first and last items in a series.

Meaning: Positioning matters! Position the most important objects first

Hope you found that useful!
