## 1 Introduction
It has developed multiple approaches and technologies to preserve and re-contextualize CH, including augmented (AR) or virtual reality (VR) storytelling [20; 21; 22], tangible interaction [23; 24], and accessible 3D replicas of CH artifacts and environments [25; 26; 27]. In the process, HCI research further emphasizes the need to protect users and build socio-emotional relationships with them, particularly when dealing with vulnerable users from minoritized groups or users with lower socio-economical status or lower digital literary skills [17]. Additionally, participatory [28] and co-design [29] approaches enable engaging users early and throughout development, ensuring their communication needs, habits, and styles are accommodated. Consequently, HCI provides tools and methods for CH re-contextualization and communication that foster an agonistic and democratized discourse. Our work builds on a research workshop about CH re-contextualization held at an international research conference in which four of the authors participated [30]. Based on these initial discussions, we applied a form of collaborative reflection [31; 32] on our individual long-term practice experiences in five online sessions, in which all authors reflected on the role of HCI advances in re-contextualizing CH toward multiperspectivity, inclusion, and sensemaking, highlighting recent developments and challenges. We focus on multiperspectivity--defined as a\"_concept expressing the willingness to take someone else's viewpoint_\" [33]--and inclusion--here focused on social inclusion in the form of _\"fostering solid bonds between groups despite their differences_\" [34]--toward empowering minoritized groups to share their perspectives and CH as equals. In addition, we aim for sensemaking, which is the process of contextualizing an experience that supports empathy, meaning, and connection-making [35; 36], which are relevant qualities for creating shared understanding. To this end, we present four case studies (see Table 1) from the authors' own research areas that have applied and explored HCI approaches, methods, and technologies in and for different contexts and purposes. Each case study highlights challenges, opportunities, and open research questions, following the guiding question:  
_How can HCI research approach CH re-contextualization to enable multiperspectivity, inclusion, and sensemaking?_Each case study further informs different project phases (from Ideation to Documentation):  
**Case 1** presents a methodological approach to enable multiperspectivity already in the _Ideation_ stage of HCI projects, fostering inclusion early in technological development. **Case 2** reflects on _Exploration and Prototyping_ as a means of communicating with Indigenous user groups to achieve a shared understanding of different cultural values more quickly. **Case 3** focuses on 3D scanning and modeling in Cultural Landscape _Analysis and Documentation_ and preservation to support decision-making in CH management and discusses digital tools to promote sensemaking through active stakeholder participation. **Case 4** discusses digital data legacies and the development of personal cultural heritage through social media and online platforms, highlighting the need for further _Evaluation_ of the increasing HCI components in CH entanglements (Figure 6). Results from our reflection emphasize the intra-dependencies between both fields, identifying HCI's crucial role in CH re-contextualization. HCI serves as a communication mediator for CH, and CH provides the foundation for prefiguring HCI. At the same time, HCI and CH increasingly converge in the form of HCI technologies turning into CH artifacts, enabling the formation of online groups or identities. Both roles require reflecting on and adapting HCI research and development approaches toward the ever-evolving CH pace and dynamics to support CH re-contextualization.
