Which term describes human product relationships?

• A. Ergonomics
• B. Anthropometrics
• C. Space Planning
• D. Programming

Answer: (A)

Ergonomics describes how people interact with products and environments, aiming to fit design to human abilities and limitations for comfort, safety, and efficiency. This field focuses on designing tools, furniture, and interfaces so that everyday use aligns with how the body moves and functions—reducing strain and increasing ease. For example, a chair that supports good posture, a computer keyboard that fits natural hand position, and kitchen counters set at heights that match typical elbow level all reflect ergonomic thinking.

Anthropometrics is about measuring body dimensions and proportions to inform design, but it’s the data used by ergonomics rather than the relationship itself. Space planning deals with arranging rooms and spaces for flow and function, not specifically how a person interacts with a product. Programming is the process of identifying needs and functions to guide design goals, not the interaction between a person and a product.
