The main focus of the human-computer interaction (HCI) field is to improve the design and use of computer technology by studying how people interact with computers. HCI aims to enhance the usability and user experience of interfaces by understanding user behaviors, needs, and preferences. It involves interdisciplinary approaches that include psychology, design, and computing, fostering the creation of intuitive, user-friendly systems. By prioritizing user-centered design, HCI research contributes to the development of software and hardware that are efficient, engaging, and effective in fulfilling user objectives, particularly in a world where technology continues to evolve rapidly.
