Principles of ergonomics include job design, health issues, and which element?

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

Answer: (B)

Ergonomics focuses on shaping work and systems around the people who use them, aiming to maximize safety, comfort, and performance. A central piece of this is the end-user interface—the way clinicians and other users interact with the system. This includes screens, layouts, controls, and feedback, which directly affect usability, cognitive load, and physical strain. Designing with the end-user interface in mind helps reduce errors and fatigue, making workflows safer and more efficient. The other terms pertain more to technical or architectural aspects (how software components talk to each other, the programming language used, or how systems are connected), and don’t directly address the human interaction that ergonomics targets.
