Research Background and Problem Statement

• Identified Issues or Challenges:

  • In the design industry, although digital tools are widely used for activities such as wireframing, prototyping, and user testing, designers still prefer traditional tools like pen and paper during brainstorming and ideation phases.
  • Can digital tools effectively support divergent and convergent thinking in the design process? Can these tools encourage designers to abandon traditional analog tools?

• Research Significance:

  • Creative problem-solving typically involves two critical cognitive processes: divergent thinking (exploring diversity and possibilities) and convergent thinking (evaluating and focusing on a single solution). Understanding the impact of digital versus analog tools on these processes is crucial for optimizing the selection and development of design tools.

• Research Motivation and Related Work:

  • While the HCI field has extensively studied the development of new digital tools to support designers' creative processes (e.g., digital sticky notes and virtual whiteboard tools), the specific impact of digital versus analog tools on divergent and convergent thinking remains unclear. Moreover, the cyclical alternation of divergent and convergent thinking forms the core of the design process and underpins models such as the "Double Diamond Model."

Solution

• Proposed Method or Solution:

  • This study designed and conducted a comparative experiment analyzing the effects of analog tools (e.g., pen, paper, whiteboard) versus digital tools (the "Cards and Boards" system) on the divergent and convergent thinking of 24 designers solving design tasks.
  • Linkography and protocol analysis methods were employed to break down the design process into specific "design moves" and assess thinking types by analyzing the number and patterns of links between these moves.

• Innovative Aspects of the Solution:

  • Linkography is a systematic method for analyzing design cognition and processes, combining quantitative and qualitative analysis to deeply explore the micro-mechanisms by which digital and analog tools influence design behaviors.
  • The comparative experimental design is rigorous, reflecting the characteristics of real design scenarios while avoiding biases, such as controlling for learning effects and order effects through task randomization and condition counterbalancing.

• Implementation Steps and Key Techniques:

  1. Experimental Design: Groups of designers completed two design tasks (e.g., developing an online service or smart home tool) using analog and digital tools, with random counterbalancing to equalize task and tool conditions.
  2. Data Collection and Analysis: Design activities were fully recorded via audio and video, high-resolution scans documented analog materials, and digital tool usage was comprehensively logged via system backend.
  3. Linkography Analysis: Protocol content was segmented into design moves, and their link relationships (e.g., isolated moves, critical moves, link index) were annotated to quantify divergent and convergent thinking metrics.

Research Findings

• Specific Results:

  • Compared to analog tools:
    • Digital tools increased the proportion of "backlinking critical moves" supporting convergent thinking from 2.6% to 7.2%.
    • The proportion of isolated moves was lower with digital tools (14% vs. 23% for analog tools), reflecting higher idea adoption rates.
    • Digital tools enhanced the density of links between moves (link index increased from 0.57 to 0.75), indicating designers were more inclined to associate and integrate information.
  • No significant differences were observed between digital and analog tools in the number of design moves or metrics supporting divergent thinking (e.g., forelinking critical moves).

• Advantages Over Existing Solutions:

  • Commercial digital tools often lack in-depth research based on design psychology, whereas this study demonstrates that the "Cards and Boards" system not only effectively replaces analog tools but also better supports the convergence process in specific contexts.

• Experimental and Evaluation Results:

  • T-test results showed statistically significant effects of digital tools on convergent thinking (e.g., backlinking critical moves, link index).
  • Analysis of video-recorded points of interest revealed that the higher information density and instant visualization capabilities of digital tools might be key contributors to their advantages.

• Limitations and Future Directions:

  • This study focused on the ideation phase of design and only explored the relative impacts on divergent and convergent thinking. Future research should incorporate additional dimensions, such as team dynamics and time pressure.
  • Long-term effects in real-world design projects and the adaptability of digital tools to team heterogeneity (e.g., diverse professional backgrounds, skill levels) warrant further investigation.
  • Experiments are needed to confirm the independent contributions of specific digital tool features (e.g., interaction modes, real-time collaboration functions) to outcome variables.
