어포던스 디자인 요소에 따른 VR 인테리어 애플리케이션의 사용자 경험 분석

Background/Objectives: As virtual reality (VR) is increasingly adopted in interior design services, understanding user experience (UX) in VR applications has become essential. This study examines UX based on affordance design elements—cognitive, physical, sensory, and functional—in a VR interior application, aiming to propose improvement directions. Methods: A total of 34 participants used a commercial VR interior application. Quantitative data were collected through structured questionnaires on each affordance element, and qualitative insights were gained from task observations and post-task interviews. Results: Users reported high satisfaction (M=4.00) with immersion (M=4.41) and efficiency (M=4.03), but reuse intention was relatively low (M=3.62) due to the lack of tutorials, limited content, and unintuitive UI. Sensory affordance received the lowest score (M=3.17), reflecting the absence of sound, haptic feedback, and smooth transitions. Cognitive and functional affordances were also limited by inadequate guidance and unclear icons. While overall task performance was good, users faced challenges in material selection and furniture manipulation. Female users reported more discomfort, especially during onboarding and navigation. Conclusion/Implications: Affordance design elements greatly impact user experience in VR interior applications. Enhancing tutorials, sensory feedback, and intuitive interactions can improve usability and immersion. These findings offer practical insights for creating more inclusive VR environments and inform future UX-focused VR research.
