Human-Computer Interaction
Human-Computer Interaction (HCI) is the interdisciplinary study of how people interact with computers and digital systems. It focuses on designing user-friendly interfaces and improving the usability, accessibility, and overall experience of technology. By understanding user behaviors, needs, and limitations, HCI aims to create systems that are efficient, intuitive, and enjoyable to use, bridging the gap between humans and machines in various applications and environments.

❓ Frequently Asked Questions
What is Human-Computer Interaction (HCI)?
HCI is the interdisciplinary study of how people interact with computers and digital systems, focusing on designing interfaces that are usable, efficient, and satisfying.
What are the core usability goals in HCI?
Effectiveness (doing tasks correctly), efficiency (doing tasks quickly), and user satisfaction, with accessibility and safety also considered.
What is the difference between UI and UX in HCI?
UI refers to the interface’s look, feel, and controls; UX covers the overall experience, including usability, emotions, and satisfaction across interactions.
Why is accessibility important in HCI?
To ensure technology is usable by people with diverse abilities, including features like keyboard navigation, screen reader support, and good color contrast.
What methods are commonly used in HCI to improve design?
User research (interviews, surveys), prototyping, usability testing, task analysis, and heuristic evaluations.
