It presents socio-economic, environmental, and historical topics through an interactive spatial display. The system supports both multi-user interaction\u2014allowing many visitors to engage simultaneously\u2014and a tour guide mode for staff-led presentations. It combines scientific, data-driven visualizations with popular-science, story-driven content and integrates both real-time and locally stored data streams. Its design and development processes are thoroughly described. A field study with 32 participants yielded a System Usability Scale (SUS) score of 84.14 and a mean User Experience Questionnaire (UEQ-S) overall score of 1.93, indicating high usability and a positive user experience. The participants found the projection technology impressive and the content informative while noting challenges such as information overload, unclear temporal structuring of the content, and minor technical issues. Planned developments focus on restructuring the content for shorter sessions, implementing a new content management system, and refining the technical stability. Finally, this work reframes projection mapping as operational infrastructure rather than a fixed display, offering practical guidance for researchers advancing PM methodologies and museum practitioners deploying innovative, technology-driven exhibitions.<\/jats:p>","DOI":"10.3390\/virtualworlds4040049","type":"journal-article","created":{"date-parts":[[2025,10,31]],"date-time":"2025-10-31T03:33:07Z","timestamp":1761881587000},"page":"49","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["The Gaia System: Revolutionizing Museum Storytelling with Projection Mapping"],"prefix":"10.3390","volume":"4","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-2741-8127","authenticated-orcid":false,"given":"Costas","family":"Boletsis","sequence":"first","affiliation":[{"name":"SINTEF Digital, 0373 Oslo, Norway"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1744-9720","authenticated-orcid":false,"given":"Ophelia","family":"Prillard","sequence":"additional","affiliation":[{"name":"SINTEF Digital, 0373 Oslo, Norway"}]}],"member":"1968","published-online":{"date-parts":[[2025,10,30]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"653","DOI":"10.1111\/cgf.13387","article-title":"Recent advances in projection mapping algorithms, hardware and applications","volume":"Volume 37","author":"Iwai","year":"2018","journal-title":"Proceedings of the Computer Graphics Forum"},{"key":"ref_2","first-page":"e00083","article-title":"Communicating the spatiotemporal transformation of architectural heritage via an in-situ projection mapping installation","volume":"11","author":"Nofal","year":"2018","journal-title":"Digit.
