PYTDR Nefeli Tentoma Authenticity in VR | 讲座视频：历史虚拟重建

Archaeological sites, as vital components of cultural heritage, embody the testimonies of the past and shape our cultural identity. Protecting and preserving these sites is crucial, particularly in today’s digital age where innovative methods, such as virtual reconstruction, offer new ways to document, visualize, and share heritage. However, virtual reconstructions often involve interpretations and hypotheses due to the fragmented state of archaeological remains, raising concerns about authenticity and the ability to distinguish evidence-based elements from speculative ones. This study explores methods to ensure the intellectual transparency and accuracy of virtual reconstructions while fostering an engaging user experience.

考古遗址作为文化遗产的重要组成部分，见证了历史，并塑造了我们的文化认同。保护和保存这些遗址十分重要。在当今数字化时代，虚拟重建等创新方法为文物的记录、可视化和共享提供了新的路径。然而，由于考古遗址的保存并不完整，虚拟重建往往涉及一定的解释和假设。于是，”真实性”则需要被先行讨论，重点关注”如何区分基于证据的要素与推测性的要素”。本研究探讨了确保虚拟重建的知识透明性和准确性的方法，目的是增强用户体验。

The research focuses on the ancient Roman Library of Pantainos, located in Athens’ Ancient Agora, as a case study. A virtually reconstructed 3D model of the site was developed using digital geometric documentation and historical research. To address authenticity, a revised graphic scale with specific color codes was introduced to indicate levels of historic-archaeological evidence, ensuring clarity in the reconstruction process. The model is presented through a Virtual Reality (VR) desktop application, enabling users to explore the site while understanding its levels of authenticity. The study highlights the importance of intellectual transparency and enhanced user experience, offering insights for future refinements in VR applications and contributing to the evolving field of digital heritage.

本研究以位于雅典古代广场的古罗马潘塔伊诺斯图书馆为案例进行研究。通过数字几何文献记录和历史研究，构建了该遗址的虚拟重建三维模型。为解决”真实性”问题，引入了一种修订后的图形比例，并结合特定的色彩编码，以表示历史考古证据的不同层次，目的是保证重建过程的清晰性。该模型通过虚拟现实（VR）桌面应用程序展示，使用户可以在探索遗址的同时，理解其“真实性”的不同层次。本研究强调了知识透明性和增强用户体验的重要性，为未来虚拟现实应用的改进提供了见解，并为数字遗产领域的发展做出了贡献。
