How Much Can VR Improve Spatial Experience? - A Case Study with a Commercial Building Project

With the development of Industry 4.0 and the impact of the COVID-19 epidemic, the global construction industry has undergone a rapid digital transformation, pushing the development of building information modeling (BIM), virtual reality (VR), augmented reality (AR) and mixed reality (MR) technologies towards greater maturity. However, from the perspective of building developers and end users, does VR technology have any benefit for complex building projects? What are users' acceptance and evaluation on VR emerging technology? After constructing a VR simulation navigation system for an actual commercial building project, this study investigated and compared the differences between using the VR system and the traditional navigation system in the four dimensions of the technology acceptance model. The results showed that the subjects generally believed that the VR system has significant benefits in terms of usefulness, users’ attitude, and users’ intention, however, there is still room for improvement in the perceived ease of use. Moreover, feedback from developers supported the benefits of the VR technology validated the system effectiveness. Hence, VR and BIM technologies are recommended to be effectively integrated, in order to enhance the integrity of industrial applications and establish a new design communication and collaboration model for the architecture, engineering, construction, and facility management industry.
