Which ergonomics principle relates to the user-facing aspect of the system design?

• A. End-User Interface
• B. Programming Language
• C. System Integration
• D. Application Interface

Answer: (A)

Ergonomics in system design concentrates on how people actually interact with the system. The part a user directly engages with—the screens, menus, controls, prompts, and feedback you see and use—is the end-user interface. Designing this well makes tasks easier, reduces mistakes, and lowers cognitive load, which is central to making the system usable in real-world practice. The other terms describe aspects that are more technical or architectural: a programming language is about how developers build the software, system integration focuses on linking components, and an application interface typically refers to how software components communicate with each other rather than the user’s direct interaction. So, focusing on the user-facing interaction points, the end-user interface is the best fit.
