Research Background and Problem

• Problem or Challenge:

  • Current research on how to meaningfully and respectfully include adults with severe intellectual disabilities in co-design remains limited.
  • The complexity of knowledge and communication increases uncertainty in design environments, requiring continuous methodological and emotional support.
  • Participatory design often relies on linguistic and cognitive expression, which is highly limited for individuals with severe intellectual disabilities, leading to constrained contributions or substitution by proxies.

• Significance:

  • Diverse and inclusive design approaches can enrich the perspectives of technology and design, ensuring fair benefits for all.
  • Fully integrating individuals with severe intellectual disabilities into the design process is not only an ethical imperative but also provides unique perspectives and insights for design.

• Research Motivation and Related Work:

  • Progress has been made in participatory design and disability-focused design, such as developing simple prototypes or personalized systems, but methodological limitations persist.
  • Existing work (e.g., simple prototypes, exploratory design methods) is often confined to specific environments and lacks long-term, in-depth interaction with users.
  • The authors propose using "Active Support (AS)" as a design methodology to establish interactive relationships with adults with severe intellectual disabilities, integrating cutting-edge Human-Computer Interaction (HCI) concepts for innovation.

Solution

• Core Methodology:

  • Introduce "Active Support (AS)" as a methodological framework to ensure individuals with disabilities can participate in activities in ways tailored to their abilities.
  • Four core principles of Active Support:
    1. Every moment has potential: Every moment can be an opportunity for meaningful participation.
    2. Graded assistance: Provide appropriate levels of support, avoiding over-assistance or neglect.
    3. Little and often: Avoid prolonged monotonous activities by maintaining engagement through short, distributed collaboration.
    4. Maximizing choice and control: Empower individuals by encouraging them to lead in making choices and controlling situations.

• Innovative Aspects of the Method:

  • Combine long-term fieldwork with core co-design methodologies to explore the potential of non-verbal communication.
  • Introduce the concept of "Partial Participation," emphasizing empowerment through support and small-scale collaboration to enable individuals with severe intellectual disabilities to express themselves.
  • Promote "Relational Autonomy" through the AS approach, focusing on the dynamics of interaction between designers and individuals with disabilities.

• Implementation Steps and Techniques:

  • The authors conducted over two years of fieldwork in community centers, using qualitative methods (e.g., field notes, photographs, and interaction videos) for data collection.
  • The vignette method was employed to organize typical design cases, illustrating the four principles of participatory design.

Research Findings

• Specific Outcomes:

  • Developed multiple design prototypes (e.g., visual aid boards, sensory vests, and speech boards) to support participation by different types of users with severe intellectual disabilities.
  • Validated the AS methodology in design practice, deepening HCI methodologies through micro-scale iterative interactions.
  • Proposed the concept of "Partial Participation" through small-scale tasks, enabling individuals with severe intellectual disabilities to partially engage and experience the design and technology process.

• Comparative Advantages over Existing Solutions:

  • Unlike traditional co-design approaches that rely on linguistic and cognitive abilities, the AS method emphasizes embodied communication (e.g., gestures, facial expressions, brief non-verbal expressions).
  • De-emphasizes the designer's dominance, highlighting the agency and participation of users during interactions.

• Experimental or Evaluation Results:

  • Case studies (e.g., using visual aid tools to help individuals express their needs) demonstrated increased depth of participation and perceived control for individuals with severe intellectual disabilities.
  • High acceptance and adoption rates of the methodology among participants and their support workers, with some support workers integrating AS principles into their daily practices.

• Limitations and Future Directions:

  • Limitations:
    • The study focuses on the early design stages and micro-level interactions, without exploring systemic or long-term strategic participation arrangements.
    • Data collection and analysis rely primarily on qualitative methods, lacking more systematic and quantitative evidence.
  • Future Directions:
    • Integrate Active Support with other co-design methodologies and apply them in broader, more complex environments.
    • Explore how supporters (family members, community workers, etc.) can adopt AS principles and sustain design outcomes.
    • Further investigate the long-term impact of partial participation on design outcomes.

Conclusion

Through this paper, the authors provide a new pathway for involving adults with severe intellectual disabilities in co-design, proposing a Human-Computer Interaction methodology based on Active Support from both theoretical and practical perspectives, offering significant insights for enhancing inclusive design.
