Which concept focuses on making products easy and comfortable to use?

• A. Ergonomics
• B. Anthropometrics
• C. Rapid Prototyping
• D. CAD

Answer: (A)

Ergonomics is about designing products to fit how people move and interact with them, so they’re easy and comfortable to use. It guides decisions about grip shape, control placement, seating and posture, reach, and how information is presented, aiming to reduce strain, mistakes, and fatigue while widening usability. Anthropometrics provides the body measurements that inform ergonomic choices, but on its own it’s just data about sizes; ergonomics uses that data to create user-friendly designs. Rapid prototyping helps test and refine usability quickly, but it’s a method, not the focus on ease of use. CAD is a design tool for creating models, not specifically about making products easier or more comfortable to use. So the concept that centers on making products easy and comfortable to use is ergonomics.
