VR/AR technology is a key enabler for new ways of immersively experiencing cultural heritage artifacts based on their virtual counterparts obtained from a digitization process. In this paper, we focus on enriching VR-based object inspection by additional haptic feedback, thereby creating tangible cultural heritage experiences. For this purpose, we present an approach for interactive and collaborative VR-based object inspection and annotation. Our system supports high-quality 3D models with accurate reflectance characteristics while additionally providing haptic feedback regarding the object shape features based on a 3D printed replica. The digital object model in terms of a printable representation of the geometry as well as reflectance characteristics are stored in a compact and streamable representation on a central server, which streams the data to remotely connected users/clients. The latter can jointly perform an interactive inspection of the object in VR with additional haptic feedback through the 3D printed replica. Evaluations regarding system performance, visual quality of the considered models as well as insights from a user study indicate an improved interaction, assessment and experience of the considered objects.

迈向有形文化遗产体验-通过触觉反馈丰富基于VR的对象检查

VR / AR技术是基于从数字化过程获得的虚拟对应物沉浸式体验文化遗产人工产物的新方法的关键推动力。在本文中，我们专注于通过附加的触觉反馈来丰富基于VR的对象检查，从而创造切实的文化遗产体验。为此，我们提出了一种基于交互式和协作VR的对象检查和注释方法。我们的系统支持具有精确反射特性的高质量3D模型，同时还基于3D打印副本提供有关对象形状特征的触觉反馈。就几何图形的可打印表示形式和反射特性而言，数字对象模型以紧凑且可流式表示形式存储在中央服务器上，它将数据流式传输到远程连接的用户/客户端。后者可以通过3D打印副本通过附加的触觉反馈共同对VR中的对象执行交互式检查。有关系统性能，所考虑模型的视觉质量以及用户研究的见解的评估表明，所考虑对象的交互性，评估和体验得到了改善。
