Matching Mind and Method: Augmented Decision-Making with Digital Companions based on Regulatory Mode Theory

Paper Information

• Research Domain: Decision-support technologies and human-computer interaction design
• Keywords: Decision-making, digital companions, assistive technologies, augmentation technologies, regulatory mode theory, user experience

Research Background and Problem Statement

• Identified Problems or Challenges:

  1. How can digital companions adapt to users' psychological states and preferred decision-making strategies to enhance acceptance?
  2. Can existing technologies provide support tailored to users' psychological states during complex decision-making processes?
  3. Current solutions lack sufficient consideration of users' subjective satisfaction and decision-making confidence.

• Significance of the Research: Enhancing human decision-making processes not only improves efficiency but also enhances user experience. Both in daily life and professional domains, addressing complex and diverse decision-making challenges requires adaptability and agility in the design of digital companions.

• Motivation and Related Work: Based on "Regulatory Mode Theory," the authors explore two regulatory modes of users—Assessment Mode and Locomotion Mode. This theory posits that individuals tend to employ evaluation and comparison strategies or action-promotion strategies in goal pursuit. Previous studies have demonstrated that when regulatory modes align with task strategies, the "Regulatory Fit Effect" can enhance user experience and satisfaction.

Proposed Solution

• Proposed Solution: The authors designed a digital companion that guides users into different psychological regulatory modes while providing decision-making strategies aligned with these modes, thereby enhancing the decision-making process and technology acceptance.

• Innovative Contributions:

  1. First application of Regulatory Mode Theory in the field of human-computer interaction.
  2. Creation of a decision-support framework based on regulatory fit, improving users' subjective evaluations of the system.
  3. Offering an optimized approach that integrates psychological states with technology design.

• Implementation Steps and Key Techniques:

  1. Using a text-based companion system to induce users into either Assessment Mode or Locomotion Mode.
  2. Comparing two strategies during decision-making tasks:
     • Global Evaluation Strategy: Users in Assessment Mode comprehensively consider all decision information.
     • Stepwise Elimination Strategy: Users in Locomotion Mode progressively filter and eliminate decision options.
  3. Measuring user satisfaction and evaluations of the companion system under different decision-making strategies through experiments.

Research Findings

• Specific Findings:

  1. When regulatory modes align with decision-making strategies, users' evaluations of decision quality significantly improve.
  2. User satisfaction with the system itself is also significantly enhanced under matching conditions.
  3. No significant impact of regulatory fit was found on decision accuracy or speed.

• Comparative Advantages Over Existing Solutions:

  1. This study focuses on users' subjective experience rather than solely on objective decision quality.
  2. The system can proactively adjust strategies to align with users' psychological states, offering greater personalization and interactivity.

• Experimental or Evaluation Results:

  1. Decision evaluations under matching conditions (mean=5.53) were significantly higher than under non-matching conditions (mean=4.63).
  2. Evaluations of the companion system also showed significant differences (matching mean=4.97; non-matching mean=3.66).
  3. No statistically significant differences were observed in decision accuracy or decision speed.

• Limitations and Future Directions:

  1. The authors employed a low-interactivity text-based system rather than highly interactive voice or visual systems.
  2. The study only examined immediate effects in specific scenarios, without exploring dynamic changes in long-term applications.
  3. The applicability of the regulatory fit effect under conditions of "uncertainty" has not been fully validated.

Conclusion

This study represents a significant step forward in the field of augmented intelligence and human collaboration. By integrating psychological theories with technology design, it validates that regulatory fit can enhance user experience and technology acceptance. The research paves the way for designing more personalized and highly interactive digital companion systems in the future, while providing theoretical and practical references for constructing technology support frameworks in complex tasks.
