在本文中，我们提出了一个以用户为中心的设计方法来开发的虚拟环境（VE），利用迭代，用户知情的过程中，在整个设计和开发周期。首先进行了初步调查，最终用户，即建筑师，总工程师和决策者的现实世界的建筑和城市规划项目，其次是传统的工作流程的研究。然后，我们确定了所需的元素，使VE在现实世界中的设置，选择适当的图形和听觉技术开发视听VE具有高水平的现实主义。我们以用户为中心的设计方法指导了一个适当的界面和评估方法的开发，以测试系统的整体可用性。VE在实验室中进行了评估，最重要的是，在用户的自然工作环境中。在这项研究中，我们提出的选择，我们所采用的设计和评估方法的一部分，成功地结合了研究目标与现实世界的project.Among其他results，这项评估表明，从一开始就涉及用户和设计师提高VE的有效性的背景下，真实的世界城市规划项目。此外，它表明，适当的现实主义水平，特别是空间化的3D声音，高细节的植被和阴影，以及呈现人群的存在，是重要的设计过程和交流设计;他们使更好地欣赏整体环境的VE，空间和物理对象的感知，以及规模感。我们相信这项研究对VE研究人员，设计师和从业者以及有兴趣在工作场所使用VR的专业人士都有兴趣。
In this paper we present a user-centered design approach to the development of a Virtual Environment (VE), by utilizing an iterative, user-informed process throughout the entire design and development cycle. A preliminary survey was first undertaken with end users, that is, architects, chief engineers, and decision makers of a real-world architectural and urban planning project, followed by a study of the traditional workflow employed. We then determined the elements required to make the VE useful in the real-world setting, choosing appropriate graphical and auditory techniques to develop audiovisual VEs with a high level of realism. Our user-centered design approach guided the development of an appropriate interface and an evaluation methodology to test the over-all usability of the system. The VE was evaluated both in the laboratory and, most importantly, in the users' natural work environments. In this study we present the choices we made as part of the design and evaluation methodologies employed, which successfully combined research goals with those of a real-world project.Among other results, this evaluation suggests that involving users and designers from the beginning improves the effectiveness of the VE in the context of the real world urban planning project. Furthermore, it demonstrates that appropriate levels of realism, in particular spatialized 3D sound, high-detail vegetation, and shadows, as well as the presence of rendered crowds, are significant for the design process and for communicating about designs; they enable better appreciation of overall ambience of the VE, perception of space and physical objects, as well as the sense of scale. We believe this study is of interest to VE researchers, designers, and practitioners, as well as professionals interested in using VR in their workplace.
