## Appendix A Framework for Physital Cultural Heritage Tourism Application Development
### Applying the Framework to the \"Memories of Kellie\" Case Study  
The \"Memories of Kellie\" application demonstrates the potential of interactive narratives and 3D environments for engaging users with digital cultural heritage (DCH). Below, the framework is applied to guide future developments of this project, by integrating gamified elements, Web3 features like NFTs, and XR technologies to enhance user engagement and promote site visits. Stage 1: Background and Vision Setting  
Define the DCH XR Context:  
The application serves as a digital gateway to Kellie Castle, offering users an immersive experience of the site's history. Its focus on interactive storytelling aligns with the role of XR technologies in conveying emotive and contextualized narratives that enhance cultural preservation and user engagement. Expanding this project with AR or mobile deployment can bridge the gap between the virtual experience and the physical site. Explore Technology Applications:* Interactive Storytelling: Enhance the current narrative with dynamic choices and branching storylines to deepen engagement. * NFTs: Offer digital collectibles tied to key historical periods or artifacts within the application, allowing users to own a piece of Kellie Castle's story. * Gamified Exploration: Introduce quests or challenges, such as solving historical puzzles, to encourage deeper interaction with the digital environment. Stakeholder Buy-In: The app can engage local heritage organizations, educational institutions, and community stakeholders. The project's ability to drive tourism, support cultural education, and preserve local history for future generations can be highlighted. Stage 2: Identify Opportunities  
Customer-Centric Needs Assessment:
* Pre-Visit Phase: Provide a web-based preview of the application, allowing users to explore Kellie Castle virtually and pique interest in visiting the site. * On-Site Phase: Incorporate AR features for in-person visitors, such as virtual guides or overlays that reveal how the castle evolved over time. * Post-Visit Phase: Allow users to share their digital journey through the application, coupled with NFTs representing their visit. Cultural and Business Asset Review:
* Identify key elements of Kellie Castle's history (e.g., architectural changes and famous events) to prioritize for gamified storytelling or digital collectibles. * Collaborate with local businesses to offer physgital souvenirs linked to NFTs earned through the application. Opportunity Mapping:
* Expand the application's reach with AR functionality, allowing on-site visitors to interact with historical overlays of Kellie Castle. * Create an NFT-based loyalty program, rewarding repeat visits or engagement with new content updates. Stage 3: Define Projects  
Matrix of Opportunities and Utilities:
* Use NFTs to offer users ownership of unique digital artifacts, such as a 3D model of Kellie Castle at different points in history. * Develop interactive, branching storylines that guide users through Kellie Castle's transformation over the centuries. * Integrate AR overlays for use on-site, synchronized with the application's desktop content. Concept Ideation:
* Introduce gamified elements, such as a 'time travel' feature where users complete challenges in each historical period to unlock rewards. * Create physgital souvenirs, blending physical and digital items, such as postcards with QR codes linked to NFTs. Stakeholder Collaboration:
* Collaborate with historians, local artisans, and educational institutions to ensure cultural authenticity and educational value. Stage 4: Scope and Planning  
Technology Partnership:* Partner with developers experienced in Unity(r), AR platforms, and blockchain to enhance the application with XR and Web3 features. Project Plan Development:
* Set milestones, such as incorporating AR overlays and designing NFTs for historical periods. * Develop a Minimum Viable Product (MVP) with a single timeline of Kellie Castle's history integrated with gamified challenges.
