As digital technologies permeate everyday life, understanding the dynamics of Human-Computer Interaction (HCI) becomes increasingly critical. This research investigates the intersection of user experience design and cognitive psychology to enhance the usability of interactive systems. This paper aims to provide an overview of Human-Computer Interaction (HCI), a field dedicated to understanding how humans interact with computers. HCI can be defined as the study of approaches, principles, and techniques that create user-friendly interfaces between people and computers. While computers lack the ability to understand human emotions or feelings, it is essential to inform them on how to respond appropriately in various situations. To facilitate this understanding, various techniques and principles are employed are designed to align computer responses with user expectations. Interacting with numerous devices simplifies user tasks, the importance of HCI in daily lives becomes evident. Ultimately, HCI reflects the continuous process of testing and refining interface designs, which significantly influences how users engage with technology in different contexts.
