Bibliographic Information

• Research Domain: Human-Computer Interaction (HCI), Digital Health, and Technology Design
• Keywords: Digital health, slow technology, screen-time reflection, YouTube, materiality, persuasive technology, user agency, environmental objects, IoT

Research Background and Problem Statement

• Identified Issues or Challenges:
  • Current internet platforms (e.g., YouTube) are overly focused on user engagement, leading to attention economy problems. This results in excessive screen time that often misaligns with users' goals.
  • Existing solutions fail to effectively help users reflect on and adjust their usage habits, especially in resisting persuasive technologies.
  • Digital tools (e.g., notifications) may cause "digital overload," making it difficult to foster meaningful reflection.
• Significance:
  • Prolonged and low-quality screen time can lead to shortened attention spans, information overload, and technology addiction.
  • Research on user agency indicates that the inability to adjust screen time directly hinders the fulfillment of user needs.
• Research Motivation and Related Work:
  • Inspired by the concepts of "slow technology" and "material-centric design," the authors propose a novel approach to materialize the cost of screen time through printed paper receipts to encourage user reflection.
  • Compared to traditional digital methods, leveraging tangible household objects may more effectively trigger reflection and behavioral change.

Proposed Solution

• Proposed Method or Solution:
  • A printing device was designed, integrated with a browser plugin, to materialize users' YouTube viewing records into printed paper receipts.
  • The receipt includes video titles, viewing duration, and total usage time, with the receipt's length representing the cost of usage.
  • The printer, composed of thermal-reactive paper and a wooden casing, aims to highlight the "cost" metaphor behind digital usage.
• Innovative Aspects:
  • Redefining the perception of screen time through "material-centric design" and cultural memory (e.g., the cost metaphor of receipts).
  • Using tangible objects to create interactions with the digital ecosystem, enhancing user reflection on screen time while avoiding digital overload caused by notifications.
• Implementation Steps and Key Technologies:
  • The system consists of three components: a browser plugin, an ESP32 module, and a cloud server:
    • The browser plugin records HTML events and timestamps during user viewing and uploads the data to the server.
    • The ESP32 module retrieves data from the server and controls the printer to print receipts.
    • A Rust-based backend service was developed to coordinate data storage and device interaction.
  • The system supports three experimental conditions:
    1. On-demand digital reflection (providing data via HTML tables).
    2. On-demand material (paper receipt) reflection.
    3. Randomly timed material reflection.

Research Findings

• Specific Findings:
  • Effectiveness of Materialization: The physicality of receipts significantly enhanced users' depth of reflection, making them more attentive to the quality and quantity of their usage.
  • User Agency Needs: Participants preferred controlling the timing of reflection (on-demand printing), though there were mixed opinions on the effectiveness of randomly generated receipts.
  • Reduction in screen time or improvement in content quality was partially driven by a self-motivated effort to produce "respectable" receipts.
• Advantages Over Existing Solutions:
  • Traditional screen monitoring tools lack appeal due to being overly digital or insufficiently tactile, whereas reflection through receipts is more intuitive and meaningful.
  • Receipts with a "cost metaphor" offer a novel way of fostering reflection while reducing unnecessary digital interference.
• Experimental and Evaluation Results:
  • In a 3-week home deployment study, all six participants reported that the system effectively increased their awareness of screen usage.
  • Responses to the randomly timed reflection method were divided: some users felt the lack of agency reduced engagement, while others believed it broadened their perspective.
  • The materiality of receipts inspired creative usage scenarios (e.g., using receipts to document "algorithm-driven content jumps").
• Limitations and Future Directions:
  • Participant samples were concentrated in high-income regions; future studies should expand to diverse cultural and socioeconomic contexts.
  • Privacy concerns regarding receipts (others potentially seeing detailed content) require further exploration and solutions.
  • Applicability to short video platforms (e.g., TikTok) and longer-term user behavior studies could be explored.
  • Recommendations include adding more flexibility to the system (e.g., combining digital and materialized methods) to accommodate different user habits and reflection needs.
