Diving into the Abyss: Exploring Deep Sea Connection and Curiosity through Virtual Reality

Research Background and Problem Statement

• What problems or challenges did the authors identify?
  The deep sea is one of the most mysterious and unexplored environments on Earth. Human interaction with the deep sea and its ecosystems is often limited by geographical, physical, and psychological factors (e.g., fear of the deep sea, geographical distance, etc.). This separation exacerbates both emotional and physical detachment from nature, making marine ecosystems seem irrelevant to human life, which in turn weakens public understanding of environmental issues and awareness of ecological conservation. The authors point out that research on using virtual reality (VR) technology to simulate deep-sea experiences is still relatively scarce. Existing prototypes and interaction designs require further testing to explore user behaviors and the underlying mechanisms of engagement.

• Why is this problem important?
  The disconnection from the deep sea diminishes people's understanding of ecosystems and hinders the cultivation of environmental awareness. This emotional and academic "nature-culture" dichotomy limits the public's ability to perceive the interconnectedness of the natural world. By simulating deep-sea experiences through VR, it is possible to allow users to experience the wonder and complexity of the deep sea, fostering curiosity and a sense of responsibility for marine conservation. Furthermore, this technology can overcome the risks and barriers of actual deep-sea exploration, enabling more people to experience the deep-sea environment.

• Research Motivation and Related Work
  The study is grounded in the theoretical frameworks of "ecological psychology" and "hydrocommons," proposing VR as a tool to connect humans with the deep sea. Previous studies have shown that VR is effective in educational environments and in fostering a sense of connection with nature, but these studies have been limited to simulations of shallow water areas and ecosystems. Research on deeper ecological experiences and their emotional and cognitive impacts remains scarce. Therefore, this study aims to fill the empirical research gap in VR simulations of deep-sea ecological experiences by designing the "Echo of the Abyss" (EotA) project to test and enhance users' sense of connection and curiosity about the deep sea.

Solution

• What methods or solutions did the authors propose?
  The authors designed a VR experience called "Echo of the Abyss" (EotA), which simulates a free-diving journey from the surface to the deep sea. Users explore the deep-sea environment by interacting with virtual marine wildlife such as seals, whales, and squids. During this process, users not only take on the role of a diver interacting with animals and the environment but also undergo a transformative embodiment process, transitioning from "human-ocean interconnectedness" to "becoming one with water," thereby deepening their sense of connection with the deep sea and its ecosystems.

• What are the innovative aspects of this solution?

  1. Integration of Theoretical Foundations: Based on the theories of "hydrocommons" and "ecological psychology," EotA seeks to evoke user empathy through "psychological and emotional connections to the deep sea."
  2. Gradual Narrative Design: The experience starts with interactions with familiar animals (e.g., seals) and gradually progresses to encounters with more "alien" species (e.g., bioluminescent corals), helping users overcome potential fears and stimulate curiosity.
  3. Embodiment Transformations: At the end of the experience, users' "bodies" are visually transformed to merge with water, allowing them to viscerally feel the impact of ecological imbalance and fostering a sense of conservation.
  4. Alleviating Deep-Sea Fear: By incorporating clear, bright underwater visuals and guiding characters (e.g., seals), the experience creates a sense of safety to mitigate fear of the deep-sea environment.

• What are the implementation steps and key technologies used?

  1. Design and Development: The interactive prototype was designed using Unity and the Meta Quest 2 platform, incorporating real-life experiences of free divers.
  2. Guided Narrative Interaction: Virtual watch prompts and animal guides assist users in completing specific tasks, such as helping an injured whale or restoring bleached coral.
  3. Embodied Interaction Control: Users perform swimming and diving motions, such as frog kicks, to enhance immersion (including features like "speed boosts").
  4. Multisensory Enhancements: Specific scenes incorporate lighting effects, music, and haptic feedback (e.g., controller vibrations) to enhance sensory perception.
  5. Research Methods: A mixed-methods study was conducted with 57 participants from different countries, collecting both qualitative and quantitative data. Tools included the Connectedness to Nature Scale (CNS) and the Self-Assessment Manikin (SAM) scale, supplemented by observations and interviews.

Research Findings

• What specific results were achieved?

  1. Emotional Impact: Participants reported enhanced curiosity, emotional connection, and a sense of responsibility toward ocean conservation. Some expressed interest in exploring real-life diving activities or participating in marine conservation efforts.
  2. User Experience Analysis: The experience heightened the sense of immersion, with most users feeling relaxed and excited. Although a few users raised concerns about the accuracy of swimming controls and underwater simulation, the overall experience was positive.
  3. Behavioral Motivation: Some participants expressed a willingness to reevaluate their relationship with the ocean after the experience.

• What are its advantages compared to existing solutions?
  EotA surpasses existing ocean-themed VR games (e.g., Subnautica) by moving beyond environmental extraction to integrate narratives of ecological conservation and encourage deeper personal reflection. Additionally, its theory-driven design (e.g., animal companions and embodiment transformations) establishes a more profound connection between users and nature.

• What were the experimental or evaluation results?

  • Qualitative Results: Users expressed strong affection for the virtual ocean environment and formed emotional connections during interactions with the animals.
  • Quantitative Results: Post-experience surveys using the CNS scale indicated a slight increase in participants' positive attitudes and curiosity about the ocean and ecology (e.g., the statement "I am curious to learn more about the ocean" received higher scores in post-test responses).
  • Emotional Assessment (SAM Scale): Participants rated the overall experience as pleasant, with certain scenes (e.g., the deep-sea coral and bioluminescent effects) receiving the highest positive evaluations.

• Limitations and Future Directions

  1. Limitations:
     • Limited sample size with group differences (e.g., varying experiences among users with different levels of diving expertise).
     • Uncertain long-term effects, as the study could not assess whether the experience has a lasting impact on user behavior (e.g., environmental conservation actions).
     • The study excluded users with severe deep-sea phobia, leaving room for further research on designing suitable experiences for such users.
     • The current experience duration (10–20 minutes) may limit its depth of impact and potential for repeated engagement.
  2. Future Directions:
     • Explore more tactile-enhanced effects in experience design (e.g., water flow simulation).
     • Add more interactive content and features that connect users to real-world marine conservation activities.
     • Further investigate the specific motivational mechanisms of design elements (e.g., embodiment, narrative tension) on emotional and cognitive outcomes.
     • Develop tailored VR solutions for users with psychological barriers or fears and evaluate their therapeutic potential.

Conclusion

This study demonstrates the potential of VR technology in simulating deep-sea experiences and fostering ecological awareness and emotional connection. Through unique narrative design, embodied interaction elements, and a theory-driven framework, Echo of the Abyss successfully provides an immersive and inspiring deep-sea exploration experience. This not only offers new pathways for the development of VR-based ecological education but also serves as a practical example of how digital media can be leveraged to promote environmental conservation. The findings lay a foundation for broader applications in marine education, ecological game design, and emotionally engaging VR simulations, while also highlighting promising areas for future exploration.
