Which principle emphasizes designs that are easy to learn and operate?

• A. Perceptible Information
• B. Simple and Intuitive Design
• C. Low Physical Effort
• D. Appropriate Space for Approach and Use

Answer: (B)

Designs that are simple and intuitive use focus on making interactions straightforward so people can learn how to use them quickly and operate them without confusion. This means controls, labels, and feedback are consistent and follow predictable patterns, so users can rely on prior experience to figure things out with little or no instruction. When something is simple and intuitive, the user’s mental model doesn’t have to be rebuilt each time they engage with the product or environment, which lowers the barrier for learning and reduces errors. This principle is the best fit for a design that emphasizes ease of learning and operation. Other principles address related aspects—such as making information perceptible to those with sensory limitations, requiring less physical effort, or ensuring there is adequate space for approach and use—but they don’t target learnability and ease of use as directly as this one does.
