Understanding Everyday Experiences of Reminiscence for People with Blindness: Practices, Tensions and Probing New Design Possibilities

Paper Information

• Field of Study: Human-Computer Interaction (HCI) and assistive technology design for people with visual impairments
• Keywords: Digital memory, reminiscence, blindness, interaction design, sensory experience, assistive technology, personalized archiving, digital media, social memory, audio recording

Research Background and Problem Statement

• Identified Issues or Challenges:

  • Existing interaction design research primarily focuses on the reminiscence experiences of sighted individuals, neglecting the significant population of blind and visually impaired individuals.
  • Technologies designed for visually impaired individuals mainly address practical issues (e.g., navigation, web browsing) rather than improving quality of life aspects such as reminiscence and reflection.

• Research Significance:

  • Reminiscence contributes to constructing life meaning, self-identity, and social connections, which are equally important for blind individuals.
  • Understanding the reminiscence practices and needs of blind individuals can empower design, enhance technology inclusivity, and reduce social marginalization.

• Research Motivation and Related Work:

  • The importance of material objects and digital content in reminiscence experiences is widely recognized, but research in this area has rarely focused on blind individuals.
  • Previous studies have inadequately explored how blind individuals use material and digital memories and the role these memories play in social reminiscence.

Proposed Solution

• Proposed Solution:

  • Conduct qualitative, field-based, user-centered research with blind individuals to understand their current reminiscence practices, challenges, and needs.
  • Based on the findings, propose design interventions, such as technologies that support blind individuals in capturing, sharing, and revisiting significant past memories.

• Innovative Contributions:

  • This study is the first to systematically include blind individuals in the exploration of reminiscence experiences, emphasizing the roles of sensory capabilities and social interactions.
  • It delves into the rich possibilities of tactile, olfactory, and auditory sensory cues in triggering memories, which have been overlooked in traditional design.

• Implementation Steps and Key Technologies:

  1. Study Design:
     • Employ a diverse sample of 9 blind participants, covering different life stages and social practices.
     • Conduct semi-structured interviews lasting 1.5 to 2.5 hours in participants' homes, documenting nostalgic objects and their contexts through home-based guided tours.
  2. Data Collection:
     • Record audio and photograph participants’ everyday objects, home environments, and memory-related object displays.
     • Gather detailed accounts of participants’ use and sharing of digital content.
  3. Data Analysis:
     • Use open coding to extract thematic data, followed by axial coding to organize it into structured models.
     • Apply semantic theme modeling and affinity diagrams to reveal commonalities and differences among participants.
  4. Key Technologies:
     • Support audio recording, AI image description, tactile photo generation, and the construction and preservation of hybrid multimedia archives.

Research Findings

• Specific Findings:

  • Summarized the diverse reminiscence experiences and practices of blind individuals, including sensory triggers, material/digital possessions, and visual narratives shared by others.
  • Identified several tensions hindering their experiences, such as the exclusionary nature of visually-based collective reminiscence activities and the challenges of managing dispersed and fragmented digital archives.

• Comparative Advantages:

  • Highlighted several unexplored design opportunity areas:
    • Designing personal reminiscence support using acoustic recordings and enhanced metadata.
    • Developing new collaborative reminiscence mechanisms for annotating and extracting photos.
    • Enhancing memory simulation through customized tactile archival methods.
  • The proposed research pathways aim to facilitate smoother interactions between blind and sighted individuals and increase sensitivity to blind culture.

• Experimental and Evaluation Results:

  • Emphasized the roles of sound, touch, and real-time interaction in data and digital design, demonstrating their potential beyond visually-oriented technologies.
  • Audio recordings emerged as the most meaningful "digital memory objects," alleviating participants' concerns about fragmented and inconsistent digital and material archives.

• Limitations and Future Directions:

  • The current study’s sample size is limited, and the findings may not be fully generalizable to the global blind population.
  • Future work could involve collaborative design workshops to explore how blind individuals redefine memory-related technological artifacts and storage methods.
  • Generative design approaches and more extensive field participation should be integrated to further enhance the ethical and practical aspects of reminiscence-related technologies.

Conclusion

This paper systematically explores the everyday reminiscence practices of blind individuals, focusing on sensory triggers, social interactions, and cultural heritage preservation. It provides new insights and design entry points, laying a solid foundation for advancing inclusive technology design and opening up further avenues for research in human-computer interaction and studies of special populations.
