A Study on the Factors Influencing Willingness to Use Virtual Reality Systems for External Evaluation of Buildings

Integrating new visualization methods based on virtual reality (VR) in the design evaluation process remains a challenge despite its expanding use in architectural design in recent years. This article proposes a VR-based evaluation model to improve the efficiency and quality of the overall architectural design process. By adopting a structural equation model in conjunction with the Technology Acceptance Model (TAM), the study examines users’ intention and perceived ease of use of VR in the design evaluation process based on a questionnaire survey using the proposed VR model of architectural and non-architectural professionals and students. The findings of the study show that the output quality plays a significant role in increasing behavioral intention to use the system, and perceived ease of use has a positive effect on perceived immersion and perceived usefulness of VR in the evaluation process. The study illustrates the importance of understanding “user perspective” and “willingness to use” in the development of VR-based systems to increase their practical use in architecture and design fields.
