노년 사용자의 상업 공간 접근성에 인지 기반 UX 디자인이 미치는 영향 - 사회적 디지털 디바이드 문제 해결수단으로 서의 UI 디자인

Background Elder people are often excluded from the benefits of smart systems due to the lack of elder-friendly UX design. This study aims to analyze and utilize the impact of UX design in commercial space for specific users with their accessibility issues. Methods The commercial space access factors were categorized into two user accessibility groups : customers of all ages and elder customers. The space access factors to commercial spaces were evaluated through UX design expert evaluation. Then, the ethnography session was conducted on five fast food stores and the total number of customers in each store were counted for cross evaluation. Results The access factors for customers of all ages and elder customers in commercial space are proven to be influential in attracting each user group. The ratio of elder customers to the total number of customers of all ages, showed a higher influence. Conclusions This study demonstrates that the UX design of space information systems affects the improvement of commercial space accessibility for elder users and encourages elder people to use digital devices and social infrastructure. Furthermore, the commercial value of UX design as an influence measurement tool was also considered.
