Disentangling the Power Dynamics in Participatory Data Physicalisation

Research Background and Issues

• What problems or challenges did the authors identify?
  During the process of Participatory Data Physicalisation (PDP), potential power dynamics may lead to extractive participation, marginalization, or exclusion. For instance, how decision-making processes between designers and stakeholders influence the planning, implementation, and construction of PDP remains insufficiently recognized and addressed.

• Why is this issue important?
  PDP is not only a data practice but also a participatory approach that can support data-driven group decision-making. However, if power dynamics are not addressed, PDP may fail to achieve its potential and could even exacerbate social inequalities. For example, data collection, problem articulation, and data dissemination might be manipulated or lack transparency, thereby impacting genuine participation and equitable outcomes.

• Research Motivation and Related Work
  The authors argue that leveraging perspectives from Data Feminism can uncover the potential impacts of power dynamics in PDP and suggest ways to improve these dynamics through transparency and reflection. Particularly, as data practices inherently involve social, technical, and localized contexts, systematic analysis of the decision-making and participatory methods behind them is necessary.

Solutions

• What methods or solutions did the authors propose?
  The authors proposed an interdisciplinary ontology combining theories from visualization and participatory design to analyze these power dynamics. Additionally, they validated its applicability using a representative dataset of 23 PDP artifacts, synthesizing six PDP agendas (Pedagogy, Action Research, Practice, Engagement, Exploration, and Validation) and suggesting key considerations to balance power dynamics.

• What are the innovative aspects of this solution?

  1. An interdisciplinary ontological framework was proposed to systematically analyze PDP artifacts and related processes.
  2. Six key agendas relevant to current PDP practices were defined, revealing the diversity of stakeholder participation in PDP.
  3. Key considerations for balancing power dynamics were proposed, such as flexible artifact construction, contextualizing data, and improving modes of expression.

• What are the implementation steps and key technologies used?

  1. Ontology Construction: Developed a 5W+H ontological dimension (Who, What, Why, When/Where, How) based on selected key literature.
  2. Systematic Literature Review: Extracted 23 PDP cases from the literature using keyword searches for analysis.
  3. Thematic Coding Analysis: Encoded and analyzed the dataset using the ontology to extract themes, sub-themes, and codes.
  4. Agenda Synthesis: Summarized six PDP agendas based on the analysis results.

Research Outcomes

• What specific outcomes were achieved?

  1. Proposed an interdisciplinary ontology for analyzing PDP artifacts and processes.
  2. Summarized six PDP agendas to reveal diversity and power dynamics in participatory design.
  3. Offered key recommendations for optimizing power dynamics, including enabling broader participant decision-making, greater freedom of expression, and improved consent mechanisms.

• How does it compare to existing solutions?

  • Integrated key research from visualization and participatory design fields, providing a more comprehensive analytical framework.
  • Incorporated Data Feminism theories to refine PDP processes and address potential inequalities through transparency.
  • Provided actionable recommendations to enhance the purposefulness and diversity of PDP design.

• What were the experimental or evaluation results?
  The authors conducted a comprehensive analysis of 23 PDP artifacts, demonstrating how these agendas function in practice and revealing the impact of power imbalances between designers and participants on construction and dissemination.

• Limitations and Future Directions

  • Limitations: The analysis excluded unpublished or insufficiently documented practices; addressing systemic constraints under different agendas remains challenging; direct interaction with PDP designers to validate the theory was not conducted.
  • Future Directions:
    • Enhance participant decision-making in the planning and deployment stages of PDP.
    • Explore more flexible artifact construction approaches to support richer expression and reflection.
    • Further investigate how these recommendations can be implemented in diverse contexts, particularly considering global diversity and the needs of marginalized groups.
