HCI stands for:

• A. Human Computer Interaction
• B. Humanized Computing Interface
• C. Health Computing Interface
• D. Human-Centered Information

Answer: (A)

HCI is the field that studies how people interact with computers and how to design interfaces that are usable, efficient, and satisfying to use. The standard expansion, Human-Computer Interaction, directly captures this focus on the collaboration between humans and computer systems. The other phrases aren’t the established term for this discipline, and they would imply different, less accurate scopes. In nursing informatics, applying HCI principles helps create user-friendly EHRs and decision-support tools, reducing errors and improving workflow for clinicians.
