Document Information

• Subject Area: Human-Computer Interaction (HCI), Sustainable Design, Novel Material-Driven Design
• Keywords: HCI textiles, Sustainability, Textile-form, Material-driven design, Multimorphic textile-forms, Materials experience

Research Background and Issues

• Identified Problems or Challenges:

  1. While textiles embedded with technology in the HCI field promote novel interactions and enriched experiences, they may exacerbate sustainability issues, such as the generation of e-waste and textile waste.
  2. The current textile production chain is fragmented, leading to overproduction of resources and underutilization.
  3. Existing solutions (e.g., modular or detachable designs) fail to fully address the inherent unsustainability of textile manufacturing systems, especially when form and material are designed separately.
  4. The acceptability of smart textiles and the integration of technology lack in-depth material understanding and practice.

• Research Significance:

  • With the development of wearable devices and smart textiles, exploring novel sustainable approaches can advance the HCI field, alleviate environmental pressures, and promote the realization of zero-waste concepts.

• Research Motivation and Related Work:

  1. The field of sustainable HCI has emphasized design beyond anthropocentrism, but there remains a significant gap between theory and practice.
  2. Material-driven design approaches have been used for designing biomaterials and biodegradable textiles, but their integration with form-shaping has been less explored.
  3. Most current HCI textile research focuses on two-dimensional forms, neglecting the three-dimensional interaction and embedding potential of textile materials.

Solution

• Proposed Solution: Introduce "Multimorphic Textile-forms" (MMTF) as a material-driven design approach aimed at designing interactive three-dimensional textiles by simultaneously considering material, form, production, and ecological impact.

• Innovations:

  1. Based on perspectives of "diversity" and "extended lifecycle."
  2. Introduces an integrated dynamic design process of "material-textile-form."
  3. Focuses on changes from design and production time to usage time, achieving zero waste and localized on-demand production.

• Implementation Steps and Key Techniques:

  1. Material/Process Analysis: Conduct a series of case studies analyzing textile production methods, including knitting, 3D printing, molding, and growing.
  2. Textile Form Classification:
     • Flat textile forms (e.g., weaving and growing).
     • Three-dimensional textile forms (e.g., molding and 3D printing).
  3. Dynamic Form Analysis:
     • Distinguish dynamic textile forms that change during design/production time versus usage time.
     • Propose multimorphic textile forms capable of changes across both time scales.
  4. Case Study Validation:
     • Provide practical cases (e.g., Programmable Knit, Zero Waste Weavers) demonstrating how to integrate dynamics at material, social, and ecological scales.

Research Outcomes

• Specific Outcomes:

  1. Proposed a clear definition and design framework for Multimorphic Textile-forms.
  2. Summarized five methods for creating textile forms, including knitting, weaving, 3D printing, growing, and molding.
  3. Demonstrated through cases like Programmable Knit and Zero Waste Weavers how to combine eco-friendly materials and dynamic change mechanisms to innovate textile forms.

• Advantages over Existing Solutions:

  1. The integrated design reduces the distributed production process issues of traditional textiles, minimizing waste.
  2. Dynamic design expands the adaptability and personalization potential of textiles.
  3. Combines interactivity and sustainability theories, exploring textiles with longer lifecycles.

• Experimental or Evaluation Results:

  • Programmable Knit: Utilized humidity-triggered programmable knit structures to achieve fully degradable and recyclable innovative textiles.
  • Zero Waste Weavers: Demonstrated the feasibility of zero-waste production through multilayered woven structures combined with thermally active fibers.

• Limitations and Future Directions:

  1. Current dynamic textile form cases mainly focus on shape changes, while other aspects such as color, scent, and energy changes remain underexplored.
  2. The application of biomaterial design is still in its exploratory phase and requires integration with more bioactive materials for sustainable production.
  3. Insufficient tools and systems exist to support modeling and visualization of complex textile temporal behaviors.
  4. Future work should develop specific design methods to better support designers in adopting the MMTF framework in practice.

Conclusion

This paper proposes the MMTF design approach, providing a theoretical foundation and practical direction for sustainability, interactivity, and dynamic design in textiles and HCI. This method encourages research and design to transcend considerations limited to a single time or scale, paving the way for sustainable smart textiles in the future.
