Designing Anekdota: Investigating Personal Metadata for Legacy

Paper Information

• Subject Area: Human-Computer Interaction and Design Research, particularly the application of personal metadata in commemoration and legacy practices.
• Keywords: Research Through Design, Legacy, Metadata, Prototyping, Interaction Design, Personal Data, Commemoration, Remembrance, Digital Legacy, HCI

Research Background and Problem

• Identified Problems or Challenges:

  1. In modern technological environments, personal metadata (e.g., location data, music listening history) often logs daily behaviors, but this metadata is typically forgotten or underutilized after an individual’s death.
  2. Practices surrounding data inheritance and commemoration are becoming significant topics in the field of Human-Computer Interaction (HCI). However, existing digital legacy management systems (e.g., Google’s "Make a Plan for My Account" or Facebook’s memorialization features) lack a design perspective that views metadata as material for commemoration.

• Significance:

  1. Through this data, individuals can reflect on the past and establish strong emotional connections by observing metadata linked to the daily behaviors of deceased loved ones.
  2. Exploring how metadata can be used to design future legacy practices provides a new perspective for inheritance and commemoration, offering both social value and design significance.

• Research Motivation and Related Work:

  1. Highlighting the value of metadata: Metadata (e.g., GPS records, music, and consumption habits) is not the content of events themselves but can offer intriguing insights into daily life.
  2. Using Research Through Design (RtD) to explore issues such as intergenerational design, data inheritance, and personal data privacy, drawing inspiration from earlier designs like "Technology Heirlooms."

Proposed Solution

• Proposed Solution: The authors developed a handheld metadata exploration device called "Anekdota," designed to enable inheritors to experience and understand the daily records of the deceased through location metadata in new ways.

• Innovations:

  1. The design concept revolves around the potential of metadata as "material for legacy practices," emphasizing the use of "Slow Technology" to guide users in reflecting and gradually discovering the meaning of metadata.
  2. Achieved the physical representation of metadata, transforming abstract data into tangible, perceivable interactive experiences through wearable devices and real-time engagement.
  3. Introduced metadata visualization with temporal and spatial dimensions, allowing exploration and filtering through cyclical time (e.g., seasons, days of the week) and linear time (e.g., years).

• Implementation Steps and Key Technologies:

  1. Research and Inspiration: Conducted semi-structured interviews with four participants to analyze the legacy potential and emotional connections of personal data.
  2. Prototype Design:
     • Experimented with and visualized ten years of the author’s location data (e.g., heatmaps, trajectories).
     • Developed initial concepts such as "Synchronous Compass" and "Forecast" to explore interactive experiences with metadata in real-world locations.
  3. Iterative Optimization:
     • Redesigned heatmaps into waveform visualizations to make metadata more vivid.
     • Added haptic feedback (e.g., vibrations) to enhance user perception, improving the experience of the watch-style device.
     • Enabled users to filter data through linear and cyclical time, exploring and interpreting hidden metadata patterns.
  4. User Testing and Evaluation: Collected data through guided urban walks and think-aloud protocols to refine the prototype and identify design themes.

Research Outcomes

• Specific Outcomes:

  1. The Anekdota prototype transformed location metadata into a physical, interactive commemorative experience, exploring how real-time metadata exploration can redefine legacy practices.
  2. Provided sensitizing concepts such as "Mystery and Traceability" and "Presence and Purposefulness" to guide future metadata design.
  3. Proposed "Imaginary Leaps" as a design direction, including using metadata for "Slow Acquaintance" and "Companionship" in commemoration.

• Advantages Over Existing Solutions:

  1. Offered richer interpretation and emotional connections than traditional data inheritance tools, transforming abstract information into concrete experiences through physicalized design.
  2. Combined interaction design with emotional research, imbuing metadata with intuitiveness and narrative quality.

• Experimental and Evaluation Results:

  1. User testing revealed that the presentation of metadata could convey personalization and presence, inspiring users to make behavioral and emotional inferences.
  2. Anekdota mitigated potential data privacy concerns through ambiguous and indirect expressions while emphasizing the narrative value of metadata.

• Limitations and Future Directions:

  1. Limitations:
     • The test data was limited to the author’s personal data, lacking deeper personalized connections for users.
     • Did not fully address potential ethical and privacy challenges related to metadata.
  2. Future Directions:
     • Enhance ethical considerations and user agency in metadata sharing.
     • Explore how larger datasets can be designed to be comprehensible and socially meaningful.
     • Develop broader usage scenarios, such as cross-cultural or family-based data legacy practices.
