Model Requirements for the Development of Extended Reality Applications in Construction Projects: A Literature Review
Bing Han, Fernanda L. Leite · Construction Research Congress 2022 · 2022
The Architecture, Engineering, and Construction (AEC) industry has explored, implemented, and reaped benefits from various Extended Reality (XR) applications. However, a large portion of these applications was developed in an ad-hoc approach for different technologies and different stages of a project. Sharing digital content among these applications is challenging, although many of them have the same development platform and original 3D model. This paper reviewed XR applications in the lifecycle of a construction project and summarized key information requirements for 3D models, development software systems, and processes for information transfer. Results show that a generic and adaptable model that satisfies these requirements can streamline the development process of different XR applications in the same project. Creating a generic model does not require additional activities. Instead, it relocates model pre-processing activities to the beginning of the XR development and precludes repetitive activities when possible. This paper contributes to the body of knowledge by specifying the requirements of a generic model that enhanced the interoperability of digital assets among XR technologies and applications.
