DIGITISATION OF HERITAGE SITES VIA AUGMENTED REALITY: Accessibility of Suzhou Gardens for the Differently Abled - A state of the art review of empirical studies

Many heritage sites in China present substantial accessibility obstacles for differently abled visitors. This study aims to answer the research question of how AR technologies are used to enhance the experience for cultural sites’ visitors, particularly for differently-abled persons. After filtering the literature on accessibility, inclusivity, and AR, 32 papers were retained, with four directly addressing the digitalisation of Chinese gardens. The review of the articles showed that AR technology has shown potential in enhancing visitor experiences at heritage sites, including in Chinese gardens, and is beneficial for differently-abled communities. It can mitigate physical obstacles and offers long-term preservation and documentation benefits; however, it needs careful integration to balance with the site's value. Inclusivity in tourism is crucial, yet there are still barriers for individuals with disabilities. Clear accessibility standards, legislative frameworks, and collaborative strategies are needed, along with enhanced training and public awareness campaigns. AR and assistive technologies present promising opportunities for cultural heritage management and social inclusion. By addressing ethical, accessibility, and user-experience challenges, they can enrich and preserve cultural heritage and promote a more inclusive society.
