I Stan Alien Idols and Also the People Behind Them: Understanding How Seams Between Virtual and Real Identities Engage VTuber Fans – A Case Study of PLAVE

Research Background and Issues

• What problems or challenges did the authors identify?
  This study focuses on the phenomenon of "seams" in VTubers (Virtual YouTubers)—moments of ambiguity or inconsistency between virtual and real identities, such as technical glitches or behavioral revelations—and how these affect audience experiences. These seams disrupt the continuity of the carefully crafted virtual identity of VTubers, potentially breaking audience immersion but also fostering emotional connections. However, existing research rarely explores how audiences perceive and respond to these seams.

• Why is this issue important?
  With the rapid growth of the VTuber market (projected to reach $498 billion by 2032), understanding the impact of seams on audience experiences can help platforms optimize content design to meet diverse user needs. Additionally, seams reveal the complex interactions between virtual and real identities, offering new perspectives on authenticity and user engagement in the digital age.

• Research Motivation and Related Work
  Existing research focuses on how VTubers construct virtual identities and interact with fans but rarely addresses audience reactions when the boundary between virtual and real identities becomes blurred. Furthermore, while the Human-Computer Interaction (HCI) field often views "seams" as obstacles in system design, recent theories on "seamful design" suggest that revealing seams can create opportunities for engagement and reflection.

Solutions

• What methods or solutions did the authors propose?
  The authors extend the concept of "seams" to the VTubing domain, redefining their role in the interaction between virtual idols and fans. Through a case study of PLAVE, a South Korean VTuber virtual K-pop idol group, they analyze the manifestations of seams and their impact on audience experiences.

• What is innovative about this solution?

  1. Proposing that seams are not merely disruptions to immersion but opportunities to enhance users' emotional connections.
  2. Defining two types of seams: technical glitches (e.g., motion capture failures) and identity revelations (e.g., performers disclosing personal information).
  3. Integrating "seamful design" theory to propose platform and content design strategies that help audiences manage seams according to their preferences.

• What are the implementation steps and key technologies used?

  1. Case Selection: Choosing PLAVE as the research subject due to the frequent occurrence of seams in their interactive content.
  2. Data Collection: Conducting interviews with 24 PLAVE fans to explore how they identify, interpret, and respond to seams.
  3. Data Analysis: Using thematic analysis to categorize and compile different patterns of audience responses to seams.

Research Findings

• What specific findings were achieved?

  1. Identified two main sources of seams: technical glitches (e.g., motion capture failures causing virtual avatar distortions) and virtual identity breakdowns (e.g., performers unintentionally revealing real personality traits or details).
  2. Audience responses to seams were categorized into two types:
     • Accepting seams: Integrating virtual and real identities to form a holistic understanding of the VTuber's multifaceted identity, thereby deepening emotional connections.
     • Avoiding seams: Steering clear of real identity information to maintain immersion in the virtual character.

• What advantages does this solution have compared to existing ones?
  Unlike approaches that view seams solely as obstacles, the authors attribute positive significance to them and propose how seamful design can enhance fan experiences.

• What were the experimental or evaluation results?
  The study found that technical seams (e.g., motion capture failures) often attracted audience interest due to their humor, converting many casual viewers into fans. Additionally, the separation or integration of virtual and real identities influenced audience patterns of long-term engagement.

• Limitations and Future Directions

  • Limitations:

    1. Respondents were predominantly women aged 20–30, limiting diversity.
    2. The study focused on PLAVE, which may not be generalizable to VTubers with lower technical capabilities or different cultural contexts.
    3. The study primarily examined fan perspectives, without adequately considering performers' views on seams.

  • Future Directions:

    1. Expanding to more diverse populations and cultural contexts to evaluate the universality of seams.
    2. Investigating how other VTuber groups and varying technical levels influence seam experiences.
    3. Exploring how performers balance work stress and authenticity demands in seamful design.

Conclusion

This study reveals the complex role of seams in VTuber content: they can disrupt audience immersion but also provide opportunities to foster authenticity and deeper interaction. Through the case study of PLAVE, the research clarifies the role of seams in fan experiences and offers strategies for designing VTubing platforms and content that flexibly accommodate seam exposure. These findings hold significant implications for the future development of virtual entertainment, content production, and the redefinition of digital authenticity.
