Which type of requirement focuses on the interaction between people and technology?

• A. Technical Requirement
• B. Human Computer Interaction Requirement
• C. System Usability
• D. Functional Requirement

Answer: (B)

Focusing on how people interact with technology is the essence of human-computer interaction requirements. This area covers designing interfaces, prompts, feedback, and workflows that fit how clinicians and other users actually work with the system, aiming to minimize errors and cognitive load while maximizing efficiency and accessibility. It’s about the user experience with the technology and how the system supports real tasks, not just what the system does or its internal technical specifications.

Technical requirements describe the hardware, software, data formats, and performance the system must have. Functional requirements specify the specific tasks and functions the system must perform. System usability addresses how easy and efficient the system is to use, which overlaps with HCI but does not inherently center on the interaction between people and technology as a defined requirement type.
