Spatial Augmented Reality (SAR) for Accessible and Engaging Spaces of Urban Heritage

Abstract

The potential of Spatial Augmented Reality (SAR), a component of the Extended Reality (XR) spectrum, is becoming evident in enhancing the engagement of cultural heritage experiences, particularly in public spaces of urban heritage, where the intersection of history, culture, and community is most profound. This paper discusses the rising interest in XR technologies within the heritage sector, their applications, and the unique challenges they present. The focus is on SAR’s capacity to augment physical spaces with immersive and interactive digital content, enriching cultural heritage experiences. The paper highlights the relevance of SAR in spaces of urban heritage, where it overlays spatiotemporal information on buildings and facilitates the concurrent participation of multiple users in a shared, sensory-enriched visual space. Emphasis is given to its potential for increased accessibility, inclusion, and the creation of site-specific content.
