Exploring Opportunities for Augmenting Homes to Support Exercising

Document Information

• Domain: Application of Augmented Reality (AR) in home fitness
• Keywords: Augmented Reality, Home Exercise, Exergaming, Home Environment, Participatory Design

Research Background and Issues

• Problems and Challenges:
  • While home exercise offers advantages such as cost-effectiveness and flexibility, some individuals experience a lack of engagement and motivation.
  • Current "exergaming" systems face limitations, such as failing to accommodate individuals with physical constraints or lacking immersive experiences.
  • Although AR head-mounted devices (AR HMDs) provide greater interactivity and immersion, there is a lack of systematic research on developing AR fitness experiences specifically for home environments.
• Significance:
  • Enhancing the interactivity, immersion, and personalization of home exercise can help a broader population overcome barriers to physical activity and improve overall activity levels.
  • Post-COVID-19, research and development in home-based exercise and exergaming may have wider societal impacts.
• Research Motivation and Related Work:
  • Existing studies primarily focus on specific areas such as medical rehabilitation or elderly care, without exploring how everyday household items can comprehensively support broader exercise methods.
  • To address these research gaps, the authors propose the following research questions:
    • RQ1: What types of exercises are suitable for augmented reality environments in homes?
    • RQ2: Which household items can be augmented to support exercise, and how can they be augmented?

Solution

• Proposed Solution:
  • Using a participatory design approach, the study conducted semi-structured interviews with 17 potential users and 2 senior physiotherapists to explore how AR technology can enhance exercise experiences in home environments.
  • Developed 10 design recommendations covering appropriate home exercises and methods for utilizing and augmenting household items.
• Innovations:
  • Conducted the first systematic investigation into how AR HMDs can support diverse exercise forms in home environments.
  • Proposed design recommendations based on user feedback, laying the groundwork for future development of home AR fitness games and motivational mechanisms.
• Implementation Steps:
  • Semi-structured interviews: Understanding users' habits, needs, and barriers to exercising at home.
  • Data analysis: Using a six-phase thematic analysis method to extract key themes related to home exercise and AR applications.
  • Consultation with physiotherapists: Supplementing user interviews with professional insights.

Research Outcomes

• Specific Outcomes:
  • Proposed four recommendations for home exercises suitable for AR environments:
    1. Focus on static exercises to avoid damaging household items.
    2. Utilize minimal or no specialized equipment.
    3. Include structured and novel elements to prevent monotony.
    4. Personalize exercises based on users' evolving needs, abilities, and interests.
  • Identified representative household items for exercise:
    • Lightweight to medium-weight items such as water bottles and canned goods for strength training.
    • Furniture (e.g., tables and chairs) for support.
    • Resistance bands or travel straps for resistance training.
  • Suggested methods for augmentation:
    • Transform everyday items into fitness equipment or motivational objects.
    • Enhance the home environment to increase immersion while avoiding information overload.
• Experimental or Evaluation Results:
  • Explored the applicability of AR HMDs in home exercise and developed preliminary design concepts.
  • Identified key points for addressing users' personalized needs, such as environmental immersion, novelty, and goal-driven motivational structures.
• Limitations and Future Directions:
  • Limitations:
    • Sample skewed toward younger participants; needs of other age groups may not be fully addressed.
    • Lack of detailed design schemes for augmenting household items.
    • Data analysis was conducted solely by the first author, introducing potential bias.
  • Future Directions:
    • Collaborate with a more diverse range of participants, AR developers, and game designers to gather multi-level design insights.
    • Explore how AR fitness can be extended to other environments (e.g., gyms, clinics).
    • Develop more robust augmentation mechanisms and prototype systems with embedded motivational structures to optimize the universality of AR fitness.

Conclusion

This study establishes a foundation for using AR HMDs to enhance home exercise experiences and proposes 10 design recommendations that provide direction for future research and development of AR fitness games. The research emphasizes the importance of personalized, user-driven design principles and explores how to make exercise more interactive, enjoyable, and immersive.
