Interface design can be a complicated process, but one front-end designer created his own set of laws to use as a guide during the design process. Using ideas from psychology to tailor his design approach to be more user-friendly, he was able to revolutionize the field of interface design and solve the riddle of how to attract and engage with users in an effective way.

  1. Jakob’s Law

This law of user experience states that users expect a website to function in a similar fashion to other websites that they already visit on a frequent basis.

  1. Law of Prägnanz

This law of user experience states that users will only comprehend complex or abstract images in the simplest form imaginable because they will be attracted to the option that requires the least amount of cognitive effort.

  1. Fitts’s Law

This law of user experience states that the size and distance of a target directly affect the time it takes to acquire the target since there is an increased chance of error the smaller and further away the target is from the subject.

  1. Miller’s Law

This law of user experience states that the human mind has a limited capacity for immediate memory and can only store an average of 7 items in their working memory, with a margin of error of plus or minus 2.

  1. Tesler’s Law

This law of user experience states that regardless of one’s best efforts, there will always be a certain degree of complexity that exists in any given system which cannot be simplified or reduced any further. This is also known as The Law of Conservation of Complexity.

  1. Law of Proximity

This law of user experience states that objects which appear close together, or in the same proximate area, are ultimately seen as being part of the same group and joined. This is a similar effect seen in movies (or motion pictures.)

  1. Hick’s Law

This law of user experience states that the complexity and number of options presented to a person will increase the time it takes for that person to make a decision based on the options.

  1. Parkinson’s Law

This law of user experience states that any task will continue to grow in size until all available time to complete the task has been spent.

  1. Von Restorff Effect

This law of user experience states that when a series of similar items are grouped together, the one item that is least like the others is most likely to be remembered best. This is also known as The Isolation Effect.

  1. Serial Position Effect

This law of user experience states that a user’s memory will latch onto the first and last item in a list or series and provide maximum retention.
