To develop an effective UI/UX design solution for the hotel reservation system redesign project, a study was conducted on over 20 user models. This analysis allowed for the identification of the system's strengths and the problems users faced in their experience of use. Among the highlighted problems were the amount of information presented on the screen, making it difficult to read and analyze; visual fatigue caused by long hours of system use; an outdated interface that made navigation and daily operations difficult; and the effort required to carry out everyday actions.To address these issues, a user-centered design solution was adopted, focusing on improving the system's usability and aesthetics. A modern and clean graphical interface design was implemented to provide easy and efficient navigation for users. In addition, a relaxing color palette and an adaptable lighting system were incorporated to reduce visual fatigue and provide a comfortable and enjoyable user experience.In summary, the user study identified users' problems and needs, allowing for the development of a more intuitive, attractive, and functional hotel reservation system.
