고령사회 노인의 운동실천을 위한 헬스케어 앱 UI/UX 사용성 평가 : 상대적 중요도 분석

Abstract

Purpose: This study aims to identify healthcare application UI/UX usability factors for older adults using the Delphi method and Analytic Hierarchy Process (AHP). Method: First, a comprehensive analysis of the panel of experts was conducted to identify a range of factors related to mobile healthcare apps for elderly users. A sample of 20 experts specializing in the fields of exercise rehabilitation, senior welfare, and UI/UX design were chosen for the Delphi study. Second, to develop the AHP hierarchy construction, we used five criteria level factors with 19 sub-criteria level factors. In a similar vein, a total of 15 experts from academia and industry participated in the survey for this study. Results: The use of the AHP was based on a multi-criteria evaluation of UI/UX usability, including aesthetics (4 items), text easiness (3 items), information structure (4 items), user control (4 items), and feedback (4 items). The results of this study showed that user control, followed by text easiness, information structure, feedback, and aesthetics, had the highest priority in the upper level of the AHP model. The global weights revealed that easy and simple words were the most significant factor, followed by considerations for customizing and accommodating elderly users, adjusting size and spacing to reduce errors, and providing support for user control. Conclusion: The findings of this study shed light on the theoretical examination and practical development of UI/UX usability in the context of healthcare applications by identifying important factors. Easy and simple words emerged as the top prioritized importance, while color and tone emerged as the least prioritized importance. The uniqueness of this study lies in its application of the Delphi and AHP for analysis.
