Use Cases for Design Personas: A Systematic Review and New Frontiers

Paper Information

• Subject Areas: User Experience Design (UX Design), Human-Computer Interaction (HCI), Social Impact Design
• Keywords: Personas, Use cases, Literature review, Human-computer interaction, Social good

Research Background and Issues

• Identified Challenges and Issues:

  • Despite the recognized advantages of the "personas" method in design, there is a lack of systematic reviews on its specific application scenarios.
  • There is insufficient evaluation of how personas provide practical value to designers and end-users in design tasks.
  • It remains to be analyzed whether personas can go beyond commercial applications to make positive contributions to social impact.

• Significance of the Research:

  • As socio-technical problems become increasingly complex, adopting personas or similar tools to understand user group needs is becoming particularly critical.
  • A systematic review can help designers better select tools and apply them appropriately in social impact design.

• Research Motivation and Related Work:

  • The literature has reviewed current research on persona generation, but there is little systematic analysis specifically focused on how personas are applied in design tasks.
  • By summarizing existing application cases and evaluation methods, the study aims to provide guidance on how to use personas more effectively.

Solution

• Proposed Solution:

  • The authors conducted a systematic literature review, collecting and analyzing 95 research papers on the application of personas in design tasks.
  • They proposed a three-tier usage model for personas in design tasks (Three-Stage Design Hierarchy Model).

• Innovative Contributions:

  • For the first time, systematically categorized and summarized the application scenarios and evaluation methods of personas across multiple fields, presenting a clear design hierarchy model.
  • Evaluated the potential of personas in the social impact domain, exploring the shift from commercial to social benefits.

• Implementation Steps and Key Techniques:

  1. Literature Search and Screening:
     • Databases searched included Google Scholar, ACM Digital Library, and IEEE Explore, using keywords such as "Personas," "Design tasks," and "Human-computer interaction."
     • Duplicate data was cleaned, and 95 final articles were selected through the PRISMA process.
  2. Data Extraction and Analysis:
     • Key information was extracted and categorized from the articles, including fields, design tasks, evaluation methods, and social goals.
  3. Proposal of the Design Hierarchy Model:
     • Persona usage was divided into three stages: user information organization, short-term design task support, and long-term strategic goal support.

Research Findings

• Specific Findings:

  • The most prominent fields include software development (40%), healthcare (20%), and higher education (16%).
  • The design task hierarchy model ranges from basic information organization to complex strategic planning for final products.
  • Proposed social impact applications of personas include improving healthcare delivery, promoting social accessibility, increasing civic political participation, and fostering cross-cultural communication.

• Advantages Compared to Existing Solutions:

  • Filled the knowledge gap on persona application cases through systematic review and quantitative analysis.
  • Described methods and potential strategies for combining personas with other user-centered design techniques.
  • Data supported the trend of personas transitioning from commercial to social goals.

• Experimental or Evaluation Results:

  • The most common evaluation methods include ethnographic observation (42%), expert validation (23%), usability testing (20%), and semi-structured interviews (15%).
  • Evaluation methods need further standardization to enhance the value assessment of personas in the design process.

• Limitations and Future Directions:

  • Limitations: Current evaluations of the actual impact of personas rely heavily on case studies or unstructured observations, lacking systematic experimental validation.
  • Future directions include:
    • Expanding the application of personas in social impact areas, such as mitigating political polarization, reducing misinformation spread, and health behavior interventions.
    • Quantitatively evaluating the combined effects of personas with other design techniques through experiments.
    • Exploring potential use cases of personas in interdisciplinary problem-solving, establishing connections with fields such as social sciences and environmental sciences.

In summary, this paper not only provides a comprehensive overview of the application of personas in design tasks but also actively explores their potential value in addressing socio-technical challenges.
