近年来，虚拟现实（VR）越来越受到建筑、工程、施工和设施管理（AEC/FM）行业的关注。VR有可能通过增强共识来提高工作流程效率。然而，目前的工作流程通常包含手动将设计文件转换为VR应用程序，这是非常繁琐的，而且通常效率低下。缺乏自动化和有效的数据交换方法和协议可能会导致设计师和其他用户在最初的几个设计周期后放弃VR。本文介绍了一个BIM-VR实时数据交换系统。该系统基于创新的基于云的BIM元数据解释和通信方法。通过允许用户在VR头显中自动同步更新BIM模型变更的功能，系统实现了较高的用户粘性，降低了工作流程的复杂性。我们在各种设计更改场景中测试了该系统，包括更改对象尺寸和更改对象类型。结果证实了可用性和效率。
Virtual reality (VR) has attracted increasing attention of the architecture, engineering, construction and facility management (AEC/FM) industry in recent years. VR has the potential to improve workflow efficiency through enhanced common understanding. However, the current workflow, which usually contains manually converting design files to VR application, is quite cumbersome and usually, inefficient. The lack of automated and efficient data exchange approach and protocol could potentially cause designers and other users to abandon VR after the first few design cycles. In this paper, we introduce a BIM-VR real-time data exchange system. The system is based on an innovative Cloud-based BIM metadata interpretation and communication method. With the function of allowing users to update BIM model changes in VR headsets automatically and simultaneously, the system achieves high user stickiness and reduces the complexity of workflow. We tested the system in a variety of design change scenarios including changing object dimensions and changing object types. Results confirmed the usability and efficiency.
