Human-Computer Interaction (HCI) research focuses on the design, evaluation, and implementation of interactive computing systems for human use, as well as the study of major phenomena surrounding them. This interdisciplinary field encompasses computer science, cognitive psychology, design, and engineering, aiming to enhance the usability, accessibility, and overall user experience of technology. Researchers investigate user behaviors, develop innovative interface technologies, and explore new ways for people to interact with digital environments, from traditional desktop applications to emerging areas like virtual and augmented reality, mobile computing, and smart devices. The ultimate goal of HCI research is to create intuitive, efficient, and enjoyable interfaces that improve the interaction between people and technology.
