• Keywords: Smartphone, User Experience, App Meaning, Interview Study, Personal Identity, Online Communities, Memory, Dependency, Digital Self-Regulation

Research Background and Questions

• Identified Problems or Challenges:

  • With the widespread use of smartphones and the diversity of apps, users have developed special attachments to certain apps, but the community lacks an in-depth understanding of the mechanisms behind this uniqueness.
  • Existing research primarily focuses on observing user behavior patterns or attributing them to addiction frameworks, neglecting the role of user autonomy and the influence of apps on personal identity.

• Why It Matters:

  • Smartphones and their apps are deeply embedded in users' lives, playing a critical role in personal and social relationships as well as emotional regulation.
  • Understanding app uniqueness can contribute to designing more user-centered technologies.

• Research Motivation and Related Work:

  • Drawing inspiration from Csikszentmihalyi and Rochberg-Halton's 1979 study The Meaning of Things, which explored how household objects interact with people to create meaning. Applying this framework to the context of smartphones may reveal the relationships between apps and users.
  • Unlike existing studies, this research aims to uncover user-driven, diverse reasons rather than relying on predefined theoretical frameworks (e.g., addiction, meaningfulness).

Solution

• Methods or Solutions:

  • Propose a research method based on The Meaning of Things framework.
  • Conduct semi-structured interviews with 60 participants aged 21 to 41, discussing the apps they consider "special" and the reasons behind this perception.
  • Use thematic analysis to extract data and explore users' motivations for choosing specific apps.

• Innovations:

  • Use "specialness" as a core analytical perspective, emphasizing individual choices and context-related user experiences.
  • Define "apps" rather than the entire smartphone as the research unit, enabling precise exploration of user behavior.
  • Provide an open dataset for future research.

• Implementation Steps and Techniques:

  • Design interview questions focusing on app specialness, organizational patterns, and their impact on identity.
  • Data collection and processing: Conduct online interviews (recorded via Zoom), transcribe and anonymize data, and perform thematic analysis.
  • Data analysis: Use a six-phase thematic analysis to identify key themes influencing app specialness.

Research Outcomes

• Specific Findings:

  • Identified five themes of smartphone app specialness:
    1. Memory and Reminiscence: Helping users recall important past moments, such as photo or video apps.
    2. Social Connection and Community Engagement: Connecting with significant others and interest groups, such as instant messaging or forum apps.
    3. Personal Identity Creation and Maintenance: Supporting identity expression and goals, such as fitness or financial management apps.
    4. Complex Emotional Relationships: Many special apps have both positive impacts and potential for dependency or conflict.
    5. Active Organization of Phone Layout: Self-regulation behaviors through app placement and notification management.

• Advantages Compared to Existing Solutions:

  • Provides fine-grained app-level analysis rather than broadly studying overall smartphone behavior.
  • Highlights users' active choices rather than focusing solely on passive use or addiction.

• Experimental or Evaluation Results:

  • The study revealed that most users attribute strong personal meaning to their special apps, which are deeply intertwined with their lives, memories, and goals.
  • Includes unique personal preferences, such as keeping obsolete but commemorative apps or using mobile apps to adjust identity perceptions.

• Limitations and Future Directions:

  • Limitations:
    • Data is limited to participants aged 21 to 41, excluding children and older adults.
    • Participants are predominantly from English-speaking countries (U.S., U.K., Canada, Australia), which may affect cross-cultural generalizability.
    • Data collection during the pandemic may have influenced certain app usage scenarios.
  • Future Directions:
    • Expand the age range of participants to analyze generational differences in perceptions of "special apps."
    • Further explore the behavioral and meaningful differences between pre-installed and user-installed apps.
    • Use natural language processing and other technologies to uncover implicit psychological and behavioral patterns in interview texts.

This study provides a new perspective on understanding how smartphone apps influence users' lives in this broad field, laying the groundwork for future research into user behavior and related issues.
