Hi friends!
I have recently made a Twitter thread and felt I had to share it with our community here :)
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!
Example from the Samsung's page
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
Example from the Amazon web page.
Hope you found that useful!
