Museu Matriosca: realidade aumentada como arquivo vivo de exposições itinerantes da Casa de Saberes Cego Aderaldo

Abstract

This study proposes the creation of the Museu Matriosca project and the use of augmented reality (AR) as a tool to digitally document and disseminate a visual record of the itinerant exhibitions held at the Casa de Saberes Cego Aderaldo, in Quixadá, throughout 2025. Grounded in a theoretical framework that addresses augmented reality, itinerant exhibitions, and the challenges of digital archiving, the research highlights the potential of WebAR as a tool for cultural mediation and for extending the lifespan of temporary exhibitions. Related projects that apply AR in museological contexts were analyzed, revealing different strategies for interaction and heritage preservation. The adopted methodology follows a qualitative approach, structured into four stages: digital curation of the collection, application architecture design, application implementation, and user evaluation. The developed WebAR application, accessible via a mobile web browser, uses technologies such as Three.js, AR.js, and WebXR to enable AR visualization of digitally reconstructed exhibition walls integrated into the physical space of the Casa de Saberes. The usability evaluation, conducted with eight participants in a real use context, combined task-based tests, a post-use questionnaire, and the application of the System Usability Scale (SUS). The results indicated high task success rates, a positive perception of navigation clarity and exhibition organization, and a SUS score of approximately 97.8 on a scale from 0 to 100. The main difficulties were related to the robustness of AR on older devices and to limitations in WebXR support. The project thus offers a technological solution that contributes to the continuity, expanded access, and digital mediation of the temporary exhibitions of the Casa de Saberes Cego Aderaldo and, potentially, of other museums that adopt the same technology.
