Investigating the Intention to Use Immersive Virtual Reality Interactive Environments (IVRIE) in Design Presentations-Through the Technology Acceptance Model(TAM)-

Despite the proven of virtual reality(VR) as an innovative design presentation tool in architecture and interior design, research on users' perceived usability of virtual environments remains limited. This study developed an immersive virtual reality interactive environment (IVRIE) capable of real-time interaction and movement. An experiment involving 46 students majoring in spatial design was conducted, revealing that IVRIE provides users with a stronger sense of immersion compared to traditional static VRs. It enhances design evaluation during both the scheme presentation and decision-making stages. Using the Technology Acceptance Model TAM) framework, the study found that perceived value(PV) and positive attitude(PA) significantly influence the intention to use(IU). IVRIE improves spatial experience, user interaction with design spaces, and understanding of spatial information. Participants preferred IVRIE over traditional methods, highlighting its efficiency and potential for future design presentations.
