The main focus of the field of human-computer interaction (HCI) is to improve the interaction between people and computers. This interdisciplinary area encompasses design, computer science, cognitive psychology, and sociology, aiming to understand how users interact with technology. HCI emphasizes usability, looking for ways to make technologies more efficient, effective, and satisfying to use. Researchers study user experiences and develop guidelines for creating user-friendly interfaces, ensuring that technology remains accessible and beneficial to a broad spectrum of users. As technology evolves, HCI continues to adapt to new devices and interaction paradigms.
