This study was conducted by census method and all population members (n=85) were studied. The data collection tools were ergonomic checklist in the library environment and a researcher-made questionnaire on the educational status of ergonomic principles. The data were analyzed by SPSS software version 22 after they were collected and entered into the computer.

Background and Aim: University libraries must meet certain criteria to enter fourth-generation libraries, one of which is the use of new technologies. The aim of this study was to identify the attitudes of library users of medical universities towards the components of augmented reality (AR) technology.
Materials and Methods: The research method was survey and type of study was applied. Quantitative research approach and research tool was a researcher-made questionnaire. The internal validity of the questionnaire was assessed through CVI and its reliability was estimated using ICC. Validity of the questionnaire was confirmed using the opinions of 10 experts in information science and AR; its reliability was obtained with Cronbach’s alpha correlation coefficient (0.96). Through the online questionnaire, data from users’ perspectives on the components of familiarity, features, application, advantages, opportunities and limitations were collected in the form of 5 Likert questions. Data analysis with SPSS 26 was used through independent t-test, ANOVA and Tukey to evaluate the status of AR components.
Results: Users’ familiarity with AR was 50.55%. 78.23% of the users agreed with AR in the libraries of medical universities. In general, the mean was 3.91 and the standard deviation was 0.63. The possibility of developing research activities, use of technology to enhance learning, advantage of attractiveness, and opportunity to develop a scientific educational program were mentioned as the most important items among other AR factors. One of the limitations of setting it up in university libraries was the lack of high-speed internet. The general attitude of users towards AR was at the desired level.
