Abstract

This study aims to evaluate the usability of the book search function in the “Dokseoro” system and propose improvement measures. To accomplish this, a heuristic evaluation by experts based on Nielsen’s principles and a user evaluation involving 10 high school students were conducted. Expert assessment revealed high levels of severity in the “Help users recognize, diagnose, and recover from errors” and “Help and documentation” domains among the ten heuristic categories, while “Aesthetic and minimalist design” and “Consistency and standards” showed excellent results. The user evaluation recorded an average accuracy rate of 92.7%, with efficiency differing by search type, and a user satisfaction score of 3.8 out of 5. Based on these findings, the study identified key problems in the book search function of the Dokseoro system and proposed the following improvements: establishing error prevention and handling systems, supporting diverse search techniques, providing terminology guidance and help documents, and strengthening visual elements to improve usability. In addition, the study suggests actively presenting subject index terms and detailed material type information contained in the bibliographic data within the interface. It also proposes the development of customized interfaces tailored to different school levels.
