## 2 Background
### Interactive CH for Preservation, Experience, and Sensemaking  
HCI research has approached interactive CH intending to preserve [22; 37; 38] and to access [39; 40] and create meaningful experiences with it [41; 42]. Work concerning preservation approaches comprises digitizing tangible [43; 44] and intangible [22; 45] CH, such as scanning physically built environments to create their 3D virtual replicas [46] and recording cultural dances [47]. One of the prominent challenges at the HCI-CH intersection is the low level of digital maturity and difficulty in accessing digital data across cultural institutions and stakeholders. Projects, such as the _Cultural Data Space_ (see [[https://en.acatech.de/allgemein/time-to-raise-the-curtain-on-the-culture-data-space/](https://en.acatech.de/allgemein/time-to-raise-the-curtain-on-the-culture-data-space/)]([https://en.acatech.de/allgemein/time-to-raise-the-curtain-on-the-culture-data-space/](https://en.acatech.de/allgemein/time-to-raise-the-curtain-on-the-culture-data-space/)), last accessed 25 March 2024), address these issues as part of national digitization strategies, aiming to create a networked infrastructure that allows easy access and sharing of data across institutions while preserving data ownership [48]. Another challenge is the limited accessibility of objects and locations. For example, [PERSON] et al. [40] developed a virtual replica of an inaccessible historic graveyard on the border between Finland and Russia. Their work highlights the benefits of enabling remote access and experiences and the ethical consideration for designers when creating a \"true\" replica of a sensitive space. These projects are only exemplary for CH digitization projects globally but emphasize the need for HCI involvement and advances in this context.  
Creating meaningful interactions of and with CH contributes to its preservation through users' socio-emotional engagement and understanding of its relevance to users' lives and beyond [49]. In-group and intergroup communication shapes the process of making sense of experiences and happens throughout all conversational platforms, including onsite and online [50; 51]. In [PERSON] et al. [50], the authors explore a social augmented reality application as a communication medium between museum visitors using voice and AR touch traces on virtual objects. The findings showed that social interaction contributes to users' immersion, engagement, and understanding. AR has been widely explored to contextualize CH through engaging and vivid storytelling, enabling users to feel, e.g., like they are becoming part of an event and decision-making processes in former times [20]. The increased personal and emotional involvement triggers empathy [52], sensemaking [20], and dialogue [1]. In another example, [PERSON] et al. [53] explore the role of context in a competitive two-player game to support agonistic remembering--the contextualized representation of information to take multiple perspectives and avoid the deterministic value system of good and bad [54]. This approach supported taking an agonist perspective but required additional information in a debriefing, revealing the challenge of balancing contextualization and engagement. These examples highlight the effectiveness of interactive technology in (re-)contextualizing CH for longer-lasting, meaningful user experiences by (a) setting information into context and (b) providing alternative means for communication.
