在本文中，我们描述了一个项目，采用以用户为中心的方法在虚拟环境（VE）的设计与增强现实主义和互动性，指导现实世界中的应用程序在城市规划/建筑和文化遗产教育领域。在现实主义方面，我们引入了一个基于图像的3D捕获过程，从照片中创建逼真的模型，然后使用高质量的视图相关算法在VR系统中显示。使用先进的植被和阴影显示算法以及3D声音进一步增强了VE。添加了高度的交互性，允许用户根据自己的需求构建和操作VE的元素，正如通过用户任务分析和基于场景的方法（目前正在评估）所指定的那样。这项工作是作为ELL资助的研究项目CREATE的一部分开发的。
In this paper we describe a project that adopts a user-centered approach in the design of virtual environments (VEs) with enhanced realism and interactivity, guided by real-world applications in the areas of urban planning/architecture and cultural heritage education. In what concerns realism, we introduce an image-based 3D capture process, where realistic models are created from photographs and subsequently displayed in a VR system using a high-quality, view-dependent algorithm. The VE is further enhanced using advanced vegetation and shadow display algorithms as well as 3D sound. A high degree of interactivity is added, allowing users to build and manipulate elements of the VEs according to their needs, as specified through a user task analysis and scenario-based approach which is currently being evaluated. This work is developed as part of the Ell-funded research project CREATE.
