Human–Computer Interaction (HCI) is an important area of computer science that focuses on the interaction between users and digital systems. With the rapid growth of software applications, websites, and mobile latforms, effective interaction design has become essential for ensuring usability and user satisfaction. This project presents a theoretical study on HCI with special emphasis on User Interface (UI) and User Experience (UX) design. The study explores key HCI principles, user psychology, and usability concepts that influence modern application design. It also examines existing systems and highlights their limitations from a user interaction perspective. A proposed user-centered approach is discussed to address these limitations. The methodology followed is qualitative and conceptual, based on secondary data sources.
