• Keywords: Idle Games, Deep Breathing, Therapeutic Games, Gamification, Behavior Triggers, User Engagement

Research Background and Problem

• Problem or Challenge:
  • Intermittent and sparse deep breathing practice remains difficult to sustain, primarily due to low motivation, time constraints, discomfort during execution, and forgetfulness.
  • Existing persuasive technologies improve engagement over long-term interventions but lack effective mechanisms for short and frequent practices.
• Significance:
  • Deep breathing has significant benefits for mental (anxiety relief), physical (cardiovascular health), and cognitive health (enhanced focus), yet its distributed practice model poses challenges for integration into daily life.
• Research Motivation and Related Work:
  • Building on the motivational mechanisms of idle games (which require minimal user interaction and reward long-term engagement), this study explores how they can promote intermittent deep breathing practices.
  • The Fogg Behavior Model (FBM) provides a theoretical framework for behavior triggers and persuasive design, focusing on "motivation," "ability," and "triggers."

Solution

• Method/Solution:

  • Developed an idle game called “BreathPurr-suade,” which uses gamified reward mechanisms to encourage users to engage in short, frequent deep breathing practices.
  • The system design integrates a core gameplay loop (action—anticipation—reward) and push/pull mechanisms to enforce breaks and attract users back.

• Innovations:

  • Introduced a gamified "push-pull mechanism," where resource limitations push users to take breaks, and reward feedback pulls them back for re-engagement, aligning with the optimal pattern for intermittent deep breathing.
  • Leveraged the behavioral patterns of idle games (e.g., the reward loops in Cookie Clicker) to transform users' willingness to practice.

• Implementation Steps and Key Techniques:

  • Game Design:
    • Developed a game with a “cat café” theme, where players earn “PawPoints” by practicing deep breathing to rescue more cats.
    • Push mechanism: Deep breathing consumes “cat food,” which is limited, forcing players to pause and wait for replenishment.
    • Pull mechanism: After prolonged inactivity, cats stop generating points, prompting notifications to re-engage users.
  • Experimental Design:
    • Validation phase: Conducted physiological experiments to test whether deep breathing combined with animations affects heart rate variability (SDNN) and other metrics.
    • 4-week user testing: Compared the game with traditional deep breathing guides in terms of motivation, participation frequency, and interval effects.

Research Outcomes

• Specific Outcomes:

  • Physiological Benefits Validation: The animations in the game did not negatively impact key indicators like heart rate variability and achieved effects comparable to traditional methods.
  • User Behavior:
    • The game increased daily participation rates for deep breathing (90.5% vs. 70.7%) and frequency (3.6 times/day vs. 2.1 times/day).
    • Reduced the interval between deep breathing practices (average return time decreased by approximately 10 hours).
    • Did not significantly change the duration of individual sessions (around 1.8 minutes/session).
  • User Experience:
    • The game significantly enhanced immersion, challenge, and progress feedback while reducing psychological burden and stress.
    • Motivation improvements were reflected in reduced feelings of compulsion (increased autonomy), though it did not significantly elevate subjective recognition of the importance and value of deep breathing.

• Comparison with Existing Solutions:

  • Compared to standalone visualizations and audio guidance, idle games effectively incentivized short, high-frequency practices.
  • Game elements reduced perceived stress and optimized the effectiveness of timed triggers.

• Limitations of Experiments or Evaluations:

  • The short experimental period could not fully validate long-term lifestyle benefits.
  • Breathing patterns were self-reported and not verified using external sensors.

• Future Directions:

  • Explore the applicability of idle games to behaviors requiring complex skills.
  • Integrate more dynamic time/environment-aware triggers to optimize timing.
  • Test the sustainability of game reward mechanisms and strategies for maintaining user interest in long-term deployments.
