TravelGalleria: Supporting Remembrance and Reflection of Travel Experiences through Digital Storytelling in Virtual Reality

Research Background and Issues

• What problems or challenges did the authors identify?

  • Travel is a meaningful yet fleeting experience. While people often document their travel experiences, fully immersive recollection and reflection on past travels remain an unresolved challenge. Traditional methods of travel documentation, such as photos and text, are effective but fail to provide comprehensive emotional recollection.
  • Existing travel documentation tools, including digital tools and features like photo albums or automatically generated memory videos, simplify the recording process but often lack support for personalized creation and deep reflection.

• Why is this issue important?

  • Travel not only enhances personal self-awareness but also promotes self-discovery and growth. Reflecting on travel memories is not just an emotional connection but can also generate new insights and reflections.
  • Exploring how innovative technologies (e.g., virtual reality) can better support travel recollection and meaning-making can enhance emotional experiences and promote the application of technology in the domain of humanistic values.

• Research Motivation and Related Work

  • This study is based on digital storytelling and combines the immersive and interactive characteristics of virtual reality to explore the possibilities of travel narratives and reflection. Compared to traditional forms, virtual reality offers a deeper immersive experience, enabling users to create and narrate their travel stories in a virtual space while triggering emotional and cognitive deep reflection.
  • The core motivation of this research is to develop a solution using virtual reality to support users in actively creating personalized travel narratives rather than merely relying on algorithm-generated content.

Solution

• What methods or solutions did the authors propose?

  • The authors designed and developed a virtual reality system called TravelGalleria. This tool leverages the immersive and interactive features of virtual reality, using the metaphor of a gallery to help users organize, create, and experience digital travel stories.
  • Users can transform travel photos, videos, and other media into interactive elements to construct personalized virtual galleries. The system also provides features such as audio narration, annotations, and text panels to support users in narrating their travel experiences in detail.

• What are the innovative aspects of this solution?

  • Immersive digital storytelling creation: Virtual reality is not just used for experiencing predefined content but also supports the creation of personalized narratives, an area that has not been fully explored in the field of technology.
  • Interaction and personalized customization: Through interactive and adjustable spatial semantics (e.g., the size and arrangement of documents), users can freely adjust, explore, and present their travel stories in a virtual environment.
  • Semi-structured guidance: The design includes thematic clusters (e.g., sub-themes of travel) and the gallery metaphor to provide users with a starting point for creation, avoiding the confusion that can arise from completely unstructured creation.

• What are the implementation steps and key technologies used?

  1. Thematic grouping and gallery layout: Users define travel themes using a "mind map" interface metaphor and group files into corresponding thematic collections. Each theme corresponds to an explorable dome gallery in VR.
  2. Interactive document processing: Users can grab, move, and adjust travel documents while associating them with audio narration and annotations to enhance recollection.
  3. Multimedia and decoration features: The system provides virtual furniture, text, audio, and annotation tools to make the gallery more vivid and personalized.
  4. Execution and testing: The system was developed using Unity and supports Meta Quest 2 virtual reality hardware.

Research Outcomes

• What specific outcomes were achieved?

  • User experience testing indicated that TravelGalleria enhances users' recollection of travel experiences and emotional reconnection while inspiring introspection and new insights. For example, some users were able to reinterpret past negative travel experiences and transform them into positive memories.
  • Through the immersion and interactivity of the VR space, users could more intuitively feel and organize their travel stories, surpassing the flat memory mode of traditional computer or smartphone screens.

• What advantages does it have compared to existing solutions?

  • Compared to tools that merely present travel documents (e.g., photo albums or automatically generated content), TravelGalleria supports users in actively creating travel narratives, emphasizing human agency over algorithmic construction.
  • Through the spatial semantics and multimedia interactivity of VR, users can design memory scenes in a personalized way, more strongly triggering emotions and meaning-making.

• What were the experimental or evaluation results?

  • User ratings showed that the system performed well in terms of usability, creative enjoyment, and facilitating reflection on travel experiences (e.g., the average user satisfaction score reached 4.2/5).
  • Results indicated that the immersive creation process enhanced the detail and emotional resonance of memories, although the depth of reflection was somewhat neutral due to time constraints.

• Limitations and Future Directions

  • Limitations:

    • Participants were primarily from younger demographics; future research should expand to more diverse age groups to explore the needs of different populations for travel reflection.
    • The current study only evaluated short-term reflection effects and did not conduct long-term follow-ups to observe users' feelings and narrative updates.
    • The system requires users to upload photos and videos, lacking the ability to record or construct memories in real-time during travel.

  • Future Directions:

    • Employ AI to assist users in creating initial content or providing creative suggestions to reduce the burden of creation.
    • Explore social or collaborative storytelling features, such as shared galleries or co-creation by multiple users.
    • Design portable general interaction tools for real-time travel recording, combined with subsequent immersive creation features in VR.

Through TravelGalleria, the authors provide a new direction for the application of virtual reality in the domain of travel memory and reflection, encouraging further research into the integration of humanistic values and technology in this field.
