What is the primary focus of human-computer interaction (HCI)?

The primary focus of human-computer interaction (HCI) is the study of how people interact with computers. This field encompasses a wide range of disciplines, including psychology, design, computer science, and ergonomics, in order to improve the usability and user experience of computer systems. By emphasizing user-centered design, HCI aims to create interfaces that are intuitive, efficient, and satisfying for users.

Understanding how individuals engage with technology allows designers and researchers to identify challenges and opportunities for improving interaction. This leads to better software, applications, and systems that meet the needs of users effectively. HCI research often involves user testing, observational studies, and iterative design processes to enhance interaction outcomes.

While the design of computer hardware, programming of user interfaces, and development of artificial intelligence can play roles in the broader landscape of technology, they are not the primary concern of HCI. Instead, these aspects may be considered components within the overall framework of how human interaction with computers is facilitated, making the study of those interactions the focal point of HCI.
