تأخیر صفر: هماهنگ سازی در زمان واقعی داده های BIM در واقعیت مجازی برای تصمیم گیری مشارکتی

Virtual Reality (VR) has attracted increasing attention of the Architecture, Engineering, Construction and Facility Management (AEC/FM) industry in recent years, as it shows a great potential to improve workflow efficiency through enhanced common understanding. A problem with current VR applications in AEC/FM is that the manual conversation from official design data (e.g., a BIM model) to VR displays is difficult and time consuming. There is a lack of automated and efficient data transfer approach between BIM and VR. In this paper, we will introduce a BIMeVR real-time synchronization system called BVRS, which is based on an innovative Cloud-based BIM metadata interpretation and communication method. BVRS allows users to update BIM model changes in VR headsets (such as Oculus Rift DK2) automatically and simultaneously. We tested BVRS in a variety of design change scenarios including changing object dimensions, changing object locations and changing object types. Results confirmed the usability and efficiency of BVRS.
