Understanding Older Adults’ (Dis)Engagement with Design Materials

Research Background and Issues

• Identified Problems or Challenges:
  The authors analyzed the participation process of older adults in the early stages of design and found that certain common design materials might lead to insufficient participation or even non-participation. For instance, craft materials (such as scissors, colored paper, and markers) might be perceived by older adults as childish or overly focused on artistic aspects, which could result in resistance to design activities. Additionally, unfamiliar or irrelevant elements in design materials or activities (e.g., content related to social media) might further disconnect older adults from the design process.

• Importance of the Issue:
  Traditionally, older adults have typically been involved in technology design activities only during the prototyping or product evaluation stages, rather than during the conceptual design and idea generation phases. By participating in design activities earlier, older adults can better reflect their needs in technological solutions, avoiding the development of technologies that are disconnected from their actual life requirements.

• Research Motivation and Related Work:
  Previous studies have pointed out that design materials influence design outcomes and users' creative expression, but these studies have primarily focused on the interactions of young or professional designers. There is a lack of in-depth research on how these materials affect motivation and creativity in the design participation of older users, especially non-professionals.

Solution

• Proposed Method or Solution:
  Through an empirical study involving two design workshops with a total of 32 older participants, the authors explored how design materials influence participation and non-participation in design activities. They investigated the roles of design cards and craft materials and examined how older adults used these materials during the design process.

• Innovative Contributions:

  1. Overcoming the Limitations of Traditional Materials: Even when participants did not use traditional design materials provided by the researchers (e.g., colored paper or cards), they found alternative ways to express creativity, such as using body movements or research equipment (e.g., cameras).
  2. Dual Role of Material Properties: Material properties could both inspire creativity (e.g., flipable paper doors sparking ideas for sensor designs) and lead to resistance by conveying inappropriate messages (e.g., "artistic standards" or a "childish" impression).
  3. Emphasis on the Diversity of Creative Expression: By encouraging the use of body language and physical movements as tools for design expression, the study showcased the potential of older adults in creative expression.

• Implementation Steps and Key Techniques:

  1. Workshop Setup: Two workshops were organized, incorporating both standard and customized design materials (e.g., design cards, craft materials).
  2. Data Collection and Analysis: Interaction analysis methods were employed to deeply analyze video recordings, participants' design outputs, and observation notes.
  3. Participant Observation and Intervention: Researchers acted as facilitators, providing necessary prompts and guidance while observing how participants interacted with design materials and the activity environment.

Research Findings

• Specific Findings:

  1. Diversity in Creative Interaction: Design cards had a positive effect on stimulating creativity, while craft materials were more often used for concretely representing and refining ideas. However, when materials failed to meet participants' expressive needs, they improvised alternative methods (e.g., body movements) to convey their design concepts.
  2. Identifying Reasons for Non-Participation: The main reasons for non-participation in design activities included:
     • Materials or activity content exceeding the skill range of older adults (e.g., "craft materials requiring artistic talent").
     • Materials or activities lacking relevance or being perceived as impractical (e.g., concerns about safety, lifespan, or the time required for technology implementation).

• Advantages Compared to Existing Solutions:

  1. Provided a detailed understanding of how older users participate in design activities and the barriers they face, particularly regarding how materials shape creativity and participation.
  2. Proposed innovative design expression methods (e.g., body language), offering new directions for future research on older adults' participation in design.

• Experimental or Evaluation Results:
  Active participation in design activities was directly related to the quality of the materials. When materials could embody participants' life experiences or inspire new ideas, the effectiveness of the design activities significantly improved. Conversely, craft materials or design cards lacking relevance often made participants feel distanced, leading to withdrawal.

• Limitations and Future Directions:

  1. The study sample had a relatively high educational background, and there was limited participation from minority groups, which may not fully represent the diversity of the older population.
  2. Future research could explore broader design environments (e.g., homes) and long-term design activities to examine older adults' participation patterns.
  3. Further development is needed for tools to capture and analyze non-traditional design expressions (e.g., gestures and body movements).

Conclusion

Through a carefully designed empirical study, the authors revealed the dual role of design materials as both "catalysts" and "barriers" in older adults' participation in design activities. Their research not only challenges stereotypes about the creativity of older adults but also emphasizes the need for material diversity and flexible adjustments to enhance older adults' active participation in early-stage technology design. This provides profound insights and valuable recommendations for future research on age-friendly design.
