What is the focus of Human-Computer Interaction?

• A. How people psychologically interact with artifacts such as user interfaces
• B. The hardware design of devices
• C. The economic aspects of tech
• D. The neuroscience of vision

Answer: (A)

Human-Computer Interaction centers on how people think, perceive, and behave when using technology, and how interfaces can be designed to fit those human abilities. The correct choice captures that focus by highlighting the psychological interaction between people and artifacts like user interfaces, which drives how we study usability, user experience, and effective design. HCI blends psychology, design, and computer science to understand users, their tasks, and the ways interfaces support or hinder performance and satisfaction. The other areas describe hardware engineering, market or cost considerations, and neural processing of vision, which may inform design in related ways but are not the primary lens through which HCI analyzes interaction.
