• Keywords: Human-Water Interaction, Fluid User Interfaces, Grand Challenges, Water Environment Technology, Water Experience Design, Ethics, Sustainability, Underwater Augmented Reality

Research Background and Issues

• Identified Problems or Challenges:

  1. Current interaction designs and technologies for water environments are often one-off designs, lacking a systematic research framework.
  2. Introducing interaction technologies into water environments faces unique challenges, such as waterproofing, the reliability of sensing technologies, and design constraints adapted to aquatic conditions.
  3. Evaluation methods for water interaction design are insufficient, particularly in studying long-term user experiences and perceptual changes in water environments.
  4. Ethical issues related to water interaction technologies, including device safety, environmental impact, and cultural adaptability, have not been adequately explored.

• Significance:

  • Combining water environments with interaction technologies can provide unique user experiences and foster innovations in fields such as health, rehabilitation, and education.
  • Enhancing the standardization and systematic research of water interaction technologies can lead to better technology design and practical problem-solving, thereby advancing the field.

• Research Motivation and Related Work: The authors observed that interaction technologies in water environments lack systematic approaches and suffer from fragmented research. By collaborating with experts in the field, they propose a series of "grand challenges" to guide future research directions. This study reviews the historical development of WaterHCI, existing frameworks, and community building, emphasizing the need for a unified framework to integrate research and promote systematic progress.

Proposed Solutions

• Proposed Solutions: The authors summarized and proposed four major categories of challenges in water interaction design through expert workshops:

  1. Technology and water environments.
  2. Interaction between users and water.
  3. Water environment experience design.
  4. Ethical issues in water environments.

• Innovative Contributions:

  • Developed a framework for the long-term development goals of water interaction technologies.
  • Proposed solutions for unique issues in water environments, including dynamic design, material innovation, and sensory-supported interaction technologies.
  • Introduced a new ethical perspective that integrates sustainability and cultural diversity.

• Implementation Steps and Key Technologies:

  • Innovations in waterproofing technologies, including the use of IP ratings to measure waterproofing while developing device designs that do not compromise interactivity.
  • Designing hardware optimized for water environments, such as enhanced buoyancy, resistance to underwater pressure, and adaptation to saltwater corrosion.
  • Building an evaluation and experience framework for water environments, considering sensory changes, long-term interaction effects, and group interactions in WaterHCI.
  • Cross-disciplinary collaboration to design sustainable and ethical water interaction devices and practices.

Research Outcomes

• Specific Outcomes:

  • Proposed a systematic research framework for the WaterHCI field, summarized based on four major challenge categories.
  • Outlined a roadmap for future research in WaterHCI, identifying technological barriers and research potential.
  • Explored the potential applications of water interaction technologies in rehabilitation, entertainment, and education.

• Advantages:

  • Shifted the field's research focus from one-off designs to a systematic framework, addressing the issue of fragmented research.
  • Provided standardized technical evaluation benchmarks, such as underwater augmented reality and device pressure resistance.

• Experimental or Evaluation Results:

  • Conducted in-depth discussions with 17 domain experts in workshops, forming systematic challenge classifications and drawing research conclusions.
  • Validated the realism and importance of the proposed challenges using existing literature and technical case studies.

• Limitations and Future Directions:

  • Limitations:
    • Most participants were from specific environments (e.g., laboratories with water technology and research resources), potentially overlooking issues in resource-limited areas.
    • The limited number of workshop participants may not have covered all possible challenges.
  • Future Directions:
    • Expand the research scope to address the adaptability of low-resource communities.
    • Further explore "dark mode" designs in the WaterHCI field.
    • Increase long-term evaluations and ethical reviews of devices.

By addressing the challenges outlined in the paper, the WaterHCI field can achieve significant technological advancements, benefiting society and driving water interaction technologies toward a more mature and systematic stage of development.
