There are several laws in Interaction Design. These psychological principles help guide designers to make intuitive user interfaces. We'll look at three popular laws: Hick's, Fitts's, and Tesler's.
New Terms:
- Hickโs Law: The more choices a person is presented with, the longer the person will take to reach a decision.
- Teslerโs Law (aka Law of conservation of complexity): Every application has an inherent amount of complexity that cannot be removed or hidden.
- Fittsโs law: The amount of time required for a person to move a 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 targetโs size, the longer it takes. source: interaction-design.org
