Virtual Museums (VMs) serve as an extension of physical museums, delivering content in digital formats. Virtual Reality (VR) technologies afford the creation of interactive virtual museum experiences with 3D artifacts, enhancing cultural dissemination by narratives based on historical artifacts for educational and entertainment purposes. However, there are notable gaps in exploring the ways to interact with virtual artifacts in VMs. In this work, we conducted workshop studies with non-expert audiences and interviewed domain experts to gather insights into 3D artifacts presentation in VMs. In addition, we investigated the digital affordances of historical artifacts in VMs and discussed opportunities for interaction design. The results provide design guidelines for the forms of presentation and outline interaction possibilities. Our findings provide insights into future forms of content curation and artifact interaction in virtual museums.
