LawS OF UX
Laws of UX is a collection of best practices that designers can consider when creating user interfaces.
Von Restorff Effect
The Von Restorff effect, also known as The Isolation Effect, predicts that when multiple similar objects are present, the one that differs from the rest is most likely to be remembered.
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.
Serial Position Effect
Users have a propensity to best remember the first and last items in a series.
Peak - End Rule
People judge an experience largely based on how they felt at its peak and at its end, rather than the total sum or average of every moment of the experience.
The Pareto principle states that, for many events, roughly 80% of the effects come from 20% of the causes.
Among competing hypotheses that predict equally well, the one with the fewest assumptions should be selected.
Law of Uniform Connectedness
Elements that are visually connected are perceived as more related than elements with no connection.
Aesthetic - Usability Effect
Users often perceive aesthetically pleasing design as design that’s more usable.
Productivity soars when a computer and its users interact at a pace (<400ms) that ensures that neither has to wait on the other.
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.
Law of Common Region
Elements tend to be perceived into groups if they are sharing an area with a clearly defined boundary.
Law of Prägnanz
People will perceive and interpret ambiguous or complex images as the simplest form possible, because it is the interpretation that requires the least cognitive effort of us.
