Reflective Spring Cleaning: Using Personal Informatics to Support Infrequent Notification Personalization

Paper Information

• Research Area: Human-Computer Interaction (HCI), Personal Informatics, Notification Management
• Keywords: Personalization, Visualization, Notifications, Disruption, Personal Informatics

Research Background and Problem

• Identified Problem or Challenge: The disruptive nature of mobile notifications has become a focus of research and public discussion, yet users exhibit relatively low engagement with existing notification management tools. This is due to factors such as the complexity of settings and the need for users to perceive clear benefits of personalization before investing time.
• Significance: Disruptive notifications not only cause user stress but also make it difficult for users to concentrate on core tasks, especially when notifications are non-urgent, irrelevant, or unhelpful.
• Research Motivation and Related Work:
  • Previous notification management tools primarily support users in actively defining their notification preferences, but users are often only willing to adjust notifications after triggering events.
  • Deep reflection on users' notification habits could serve as a motivational factor, but the reflection process itself is complex and time-consuming.
  • Personal informatics tools have demonstrated the effectiveness of reflection in behavior improvement in other domains, such as mental health.

Solution

• Proposed Method/Solution:
  • Introduce the concept of "Reflective Spring Cleaning," combining notification management with personal informatics visualization to enhance user experience through infrequent reflection and personalization (e.g., every six months).
  • Develop a data abstraction model called "Who-What-When" to simplify and visualize notification usage trends.
• Innovations:
  • Simplified personal informatics visualization helps users identify and reflect on key trends in notification usage, breaking away from the current model of frequent personalization suggestions that disrupt users.
  • Integrate deep reflection with hybrid proactive personalization suggestions to make notification management more action-oriented.
• Implementation Steps:
  1. Design the data abstraction model and integrate user behavior trends.
  2. Develop a notification visualization tool incorporating the "Who-What-When" data abstraction.
  3. Evaluate the design using a lightweight HTML prototype.
  4. Conduct long-term logging of notification usage, followed by user-driven personalization actions.
  5. Conduct interviews to reflect on the impact of personalization on user experience.

Research Findings

• Specific Results:
  • The study demonstrated that the "Reflective Spring Cleaning" design effectively encouraged users to deeply reflect on their notification habits.
  • Reflection increased users' motivation to personalize notification management, significantly improving their notification experience, including reduced stress and disruption.
  • The "Who-What-When" data abstraction provided practical and actionable insights.
• Advantages:
  • Compared to traditional hybrid proactive personalization systems, it reduced frequent disruptions while enhancing user experience through the added value of reflection.
  • Offered clear action recommendations to address the challenge of converting reflection into actionable steps in personal informatics.
• Experimental Results:
  • A total of 21 participants completed the study, with over half reporting significant improvements in their notification experience. On average, users personalized approximately 28% of their notifications.
  • Simple reflection and visualization significantly enhanced users' ability to manage notifications.
• Limitations and Future Directions:
  • The prototype design was low-fidelity; future work should develop features that directly connect notification visualization with personalization settings.
  • Data primarily came from users willing to engage in notification management; broader validation with general user groups is needed.
  • Explore expanding "Reflective Spring Cleaning" into a more comprehensive personal health and behavior management system.

This study demonstrates that combining personal informatics with personalization tools not only enhances the value of reflection but also offers important insights for system design across multiple domains.
