Protocols for the Graphic and Constructive Diffusion of Digital Twins of the Architectural Heritage That Guarantee Universal Accessibility through AR and VR

Abstract

The objective of this article is to generate and validate a workflow that allows us to use virtual twins obtained from unique buildings of our architectural heritage. These twins will guarantee the preservation and dissemination of cultural assets and will promote universal accessibility through new technologies, such as databases, metaverses, virtual reality, augmented reality or gamification. This universal accessibility is based on new metaverses to offer experiences that allow us to overcome physical barriers and reach any user regardless of their economic or physical condition or their location. To obtain this workflow, we worked with digital twins obtained by photogrammetry. Different databases and metaverses were studied, understanding them as new systems for the representation and dissemination of architecture. These metaverses were critically assessed and screened, looking for the most suitable one to be integrated into an effective workflow that satisfies a series of imposed premises, such as being suitable for use in virtual reality and augmented reality environments. The ultimate goal is the aforementioned universal accessibility. © 2022 by the authors.
