This paper uses the eye tracking technique to explore user experience in the library space to understand what first captures the user's attention and which areas of the library attract the most attention. Research on user experience in libraries emphasises the importance of designing spaces, services, and library resources to improve user interaction with the library. The theoretical section provides explanations of key concepts such as user experience, user experience in libraries, and eye tracking technique, with a review of relevant studies that employed eye tracking in library settings. The research was conducted among nine students of the University of Zadar, who participated in a series of tasks in the University campus library. The study employed Tobii Pro Glasses 3 glasses, which enable a precise analysis of the user's gaze and attention, which helps optimise the library's layout and signage. In the eye-tracking study, the arrangement of library materials and shelf labels was analysed from the perspective of the study's participants. The results showed that clear signage and transparent organisation of the library improve navigating the library space and make it easier for the user to use the space. At the same time, the need for visible markings and the occasionally unclear book arrangements create challenges for users. Based on the findings, recommendations for improving the layout and signage within the library were provided.
