This study aims to propose an improved UI design for kiosk systems that allows senior users, who are often marginalized by the rapid pace of digital culture, to use kiosks more conveniently and efficiently. For this purpose, a survey was designed applying the national guidelines for unmanned information terminals and Jakob Nielsen's ten heuristic principles to evaluate usability among 150 seniors aged 50 and above. To ensure the validity of the questionnaire, it underwent two rounds of expert evaluation to verify the reliability and validity of the survey items. The survey was conducted over approximately one week, and data analysis was performed using SPSS 27.0 software. The survey results revealed that many users experience major inconveniences due to "complex selection steps" and "reduced readability from small text," indicating the need for improvements in the visibility and intuitiveness of the kiosk UI. Additionally, the necessity to simplify the menu selection process and the low average scores for recovery and control items highlight the need to enhance user experience. Accordingly, this study proposes UI improvements suitable for seniors, including enlarging key buttons, visually differentiating advertising elements, and simplifying menu selection. This research not only aims to enhance digital accessibility for the elderly but also provides a foundation for efficient kiosk usage across various age groups, and it is expected to serve as a guideline for future UI design.
