We present a framework for alternative reality (XR) technologies to enable an understanding of what constitutes an XR environment when used in the context of design and engineering of large, complex systems. The framework provides guidelines for implementing the corresponding desired human sensory experience. This work is founded on the existing literature which defines theoretical Spectra, such as Fidelity, to systematically characterize an XR environment taxonomy. We identify landmarks for four XR categories within these Spectra and provide definitions that can used to establish a common vernacular. We further map these to specific human sensing modalities that are influenced by XR, such as tactility and vision, and define the technical requirements needed to augment the human experience in the desired XR environment. Finally, we connect the theoretical elements to the technical requirements to create an integrated XR framework. The utility of this framework is demonstrated in a case study addressing the use of XR technologies for five stakeholder groups involved in the evaluation of spacecraft habitat design and operations. This demonstrates the utility of the proposed XR taxonomy in a spacecraft habitat design process, which could be extended to other similar applications.

我们提供了一个替代现实（XR）技术的框架，以使您能够理解在大型复杂系统的设计和工程环境中使用XR环境的构成。该框架为实施相应的所需人类感官体验提供了指导。这项工作是建立在现有文献的基础上的，该文献定义了诸如Fidelity之类的理论光谱，以系统地表征XR环境分类法。我们在这些“光谱”中识别四个XR类别的地标，并提供可用于建立通用白话语的定义。我们进一步将这些映射到受XR影响的特定人类感知模式，例如触觉和视觉，并定义在所需XR环境中增强人类体验所需的技术要求。最后，我们将理论要素与技术要求联系起来，以创建一个集成的XR框架。在一个案例研究中证明了该框架的实用性，该案例研究了XR技术在五个参与航天器栖息地设计和运行评估的利益相关者团体中的使用。这证明了拟议的XR分类法在航天器栖息地设计过程中的实用性，可以将其扩展到其他类似的应用程序中。
