Alternative reality (XR) tools are becoming more commonplace in the realm of architecture, engineering, and construction (AEC); however, these digitally immersive technologies vary greatly in their degree of virtuality and individual capabilities. While many studies detail the performance of one specific XR technology for a particular use case, little work exists comparing numerous modern XR technologies in a side-by-side manner for a single use case. In this work, we construct four equal-fidelity, alternative reality environments for the application of spacecraft habitat design evaluation, starting with a baseline habitat mockup constructed in physical reality (PR). Three digital environments—augmented reality, hybrid reality (HR), and virtual reality—were modeled after the PR environment and developed in parallel. The implementation of each environment was carefully documented, along with relative strengths and weaknesses associated with both development and use. Additionally, we have developed a novel HR implementation that includes realistic and intuitive haptics, hand tracking, a fully virtual audiovisual scene, and responsive habitat elements, all wirelessly synched with a game engine and spatially synched with the PR environment. In sum, this work serves as a resource for those considering XR technologies for any variety of applications, particularly in AEC disciplines.

替代现实（XR）工具在建筑，工程和建筑（AEC）领域正变得越来越普遍。但是，这些数字沉浸式技术的虚拟化程度和个人功能差异很大。尽管许多研究都针对一种特定的用例详细介绍了一种特定XR技术的性能，但很少有工作可以并排比较单个用例的众多现代XR技术。在这项工作中，我们构建了四个等逼真度，替代现实环境，用于航天器栖息地设计评估的应用，从物理现实（PR）中构建的基线栖息地模型开始。在PR环境之后对三个数字环境（增强现实，混合现实（HR）和虚拟现实）进行了建模并并行开发。仔细记录了每个环境的实施情况，以及与开发和使用相关的相对优势和劣势。此外，我们已经开发了一种新颖的HR实施方案，其中包括逼真的直观触觉，手部跟踪，完全虚拟的视听场景以及响应性的栖息地元素，它们均与游戏引擎无线同步，并与PR环境在空间同步。总而言之，这项工作为那些考虑将XR技术用于各种应用程序的人们提供了资源，尤其是在AEC学科中。和响应性栖息地元素，它们都与游戏引擎进行无线同步，并与PR环境进行空间同步。总而言之，这项工作为那些考虑将XR技术用于各种应用程序的人们提供了资源，尤其是在AEC学科中。和响应性栖息地元素，它们都与游戏引擎进行无线同步，并与PR环境进行空间同步。总而言之，这项工作为那些考虑将XR技术用于各种应用程序的人们提供了资源，尤其是在AEC学科中。
