Human-Computer Interaction (HCI) is the study of how people interact with computers and other technological systems. It involves understanding user behavior, needs, and preferences, and designing interfaces and interactions that are intuitive, efficient, and enjoyable.
HCI consists of three parts: the user, the computer itself, and the ways they work together. Some examples of human-computer interaction include: IoT technology, Eye-tracking technology, Speech recognition technology, AR/VR technology, and Cloud computing. HCI is important for designing intuitive interfaces that people with different abilities and expertise can access. It's also helpful for communities that lack knowledge and formal training on interacting with specific computing systems. Activity theory is used in HCI to define and study the context in which human interactions with computers take place. HCI improves the user experience of how we interact with technology. User Experience (UX) focuses on the implementation part of the findings that HCI provides. In UX, we study how someone uses a system, identify where they are having problems, try to improve the experience, and implement the solution.
