Principles of Usability

Principles of usability focus on making products, services, or information easy and satisfying to use. Key principles include: **learnability**, where new users can quickly understand how to use a system; **efficiency**, enabling users to complete tasks with minimal effort; **memorability**, allowing users to easily retain knowledge of how to use a system after a break; **error prevention**, designing to minimize mistakes; and **satisfaction**, ensuring users enjoy the experience. Together, these principles enhance user interactions, making them more intuitive and effective for everyone.
