This graduation project focuses on designing an interactive experience for Titanic: The Human Story, a traveling exhibition by Musealia. The goal was to help curious young adult visitors connect emotionally with real individuals who were on board the Titanic, through an interaction embedded in the existing exhibition flow. The process followed a double diamond structure. Research included a literature review on emotional engagement in cultural heritage, an analysis of over 40,000 visitor comments, and a market scan of other Titanic related exhibitions. Since the exhibition was located abroad, participants explored it in virtual reality. Their responses were observed and discussed to understand how they engaged with the content and atmosphere. The final design involves a physical postcard that visitors collect at the start. As they move through selected rooms, they stamp the card in response to thematic prompts. These choices gradually match them with a real Titanic passenger. In the final room, they receive a printed message from that person and are invited to write a response. The postcard becomes a personal record of the experience. User testing showed that all participants felt a personal connection to their assigned passenger, especially after reading the final message. The earlier stages often triggered curiosity and surprise, while the last step encouraged reflection for most, though not all, participants. This project suggests that physical interaction and narrative can strengthen personal engagement while honoring sensitive stories.
