Diagramming Working Field Theories for Design in the HCI Classroom

Document Information

• Subject Area: Human-Computer Interaction (HCI) education and design theory
• Keywords: HCI education, field research, perceptual concepts, visual thinking, design research, HCI classroom, interaction design education

Research Background and Issues

• Identified Problems or Challenges:

  1. The HCI field provides limited support for transitioning insights or theories from field research into design outcomes, particularly for beginners (e.g., students), where this transition lacks clear pathways.
  2. Students often face challenges in bridging detailed theories and practical design, relying on subjective assumptions or "marketing-style" self-rationalization during design decisions instead of grounding them in clear theories and field experiences.
  3. Traditional teaching methods in HCI courses are disconnected from the multidisciplinary backgrounds and design knowledge needs of students.

• Importance of the Issues:

  1. Building bridges between "field research" and "design processes" is critical for generating more meaningful and practical designs.
  2. Providing structured support can better assist students in transitioning from theory to design outcomes while enhancing creativity and relevance in design.

• Research Motivation and Related Work:

  1. This study is inspired by research methods such as rapid ethnography and contextual inquiry, combined with experience-focused HCI theories.
  2. It references common UX design methods (e.g., personas, customer journey maps) and academic literature on interaction design theories and intermediate-level knowledge.

Solution

• Proposed Method or Solution:

  • A working theoretical framework named "Field Theory" is introduced, which systematizes key insights and perceptual concepts related to specific design domains to guide interaction technology design.

• Innovations:

  1. "Field Theory" is proposed as an integrative framework for design education, combining field research, theoretical study, and design activities to mutually reinforce design insights and theoretical validation.
  2. "Field Theory" is presented in the form of visual diagrams to support clear communication and critical analysis.

• Implementation Steps and Key Techniques:

  1. Theory and Technology Inspiration: Students are guided to identify design opportunities through HCI theories (e.g., motivation theory) and example technologies (IoT, interaction prototypes).
  2. Field Research: Ethnographic methods are used to collect data, including interviews and cultural probe tools, to extract insights from the design context.
  3. Constructing Field Theory Diagrams: Students create simple, comprehensible diagrams based on field research results and perceptual concepts, emphasizing design opportunities and problem domains.
  4. Prototype Design and Testing: Student groups experiment with prototype designs to validate the field theory, translating the design process into tangible outcomes.
  5. Iteration and Optimization: Prototypes are introduced into field trials, allowing for reevaluation and refinement of the field theory.

Research Outcomes

• Specific Outcomes:

  1. Field theory diagrams serve as an effective structure for summarizing domain insights and guiding students in design.
  2. Students improved their ability to integrate perceptual concepts and strengthened the connection between theory and practical design through this framework.

• Advantages:

  1. Clearly supports students in overcoming cognitive and technical barriers during the transition from theory to design.
  2. Encourages creative design and critical thinking, focusing students on "real design contexts" rather than generic technical solutions.
  3. Reduces premature "marketing-style" self-reactions among students, emphasizing solutions to real experiential problems.

• Experimental or Evaluation Results:

  1. Evaluations of over 5 years and approximately 180 student projects revealed that the field theory framework significantly improved design thinking and interaction outcomes in classroom design practices.
  2. Students reported that creating field theory diagrams was a key skill for connecting theory and practice, particularly for STEM students without design backgrounds.

• Limitations and Future Directions:

  1. Some students found the framework's initial learning curve steep, with theoretical concepts being difficult to grasp, especially abstract HCI theories.
  2. The applicability of the field theory framework tool for larger-scale, multi-year studies and projects involving multiple stakeholders needs further exploration.
  3. Revised field theory methods may require higher academic rigor, such as vertical and horizontal validation strategies, to suit graduate-level and academic research contexts.
