• Keywords: Sleep, Social VR, VRChat, Experience, Motivation, Virtual Reality, Sociality, Hardware Challenges, User Habits, Bodily Perception

Research Background and Problem Statement

1. Identified Problems or Challenges:

   • The importance of sleep quality for physical and mental health is widely recognized, yet modern society faces prevalent issues of insufficient and poor-quality sleep.
   • While there have been clinical studies on using VR to assist sleep, these primarily focus on improving sleep quality and lack attention to experiential and practical aspects of sleep.
   • Very few studies have explored the impact of VR technology on sleep culture and experience, particularly in non-clinical settings involving autonomous VR sleep practices.

2. Significance of the Research:

   • VR offers unprecedented immersive experiences, enabling the creation and enhancement of spaces that are difficult to achieve in the real world.
   • Understanding the motivations and experiences of sleeping in VR can expand our knowledge of human sleep behaviors and their relationship with technology, while also providing recommendations for improving VR design and applications.

3. Research Motivation and Related Work:

   • Previous research has primarily focused on the interactivity of social VR and the construction of virtual societies, with little in-depth exploration of the culture and experience of sleeping in VR.
   • This study aims to delve deeper into why people choose to sleep in VR (motivations) and how they engage in this activity.

Proposed Solution

1. Proposed Methodology:

   • Conduct semi-structured interviews with 14 participants who have experience sleeping in VR to deeply explore their motivations and experiences.
   • Use inductive thematic analysis to extract core motivations, experiential elements, and challenges, along with suggestions for improvement.

2. Innovative Contributions:

   • The first study to focus on the unique cultural phenomenon of VR sleep, providing guidance for future VR application designs.
   • Redefines the motivations and significance of sleeping in VR from the perspectives of "experience" and "social interaction."

3. Implementation Steps and Techniques Used:

   • Study Design: Recruit 14 participants through online channels and snowball sampling.
   • Data Collection: Conduct 45-minute in-depth discussions via remote voice/video interviews, with audio recordings for subsequent analysis.
   • Data Analysis: Perform thematic analysis, coding interview data into themes and categories to identify core themes.

Research Findings

1. Specific Findings:

   • Motivations for intentionally sleeping in VR can be categorized into two main types:
     1. Experiential Motivations: Enjoying the immersive and novel experiences provided by VR environments, such as a beautiful starry sky or a peaceful rainy night.
     2. Social Motivations: Experiencing intimacy by sleeping with friends, simulating physical interactions like virtual cuddling.
   • The experience of VR sleep involves preparation of both virtual and physical spaces, such as adjusting equipment, selecting virtual sleep worlds, and configuring virtual body postures.

2. Advantages and Innovations:

   • Transforms a private activity—sleep—into a social behavior.
   • Provides a means to escape the pressures or unfavorable conditions of the real world, such as noisy or undesirable living environments.
   • Offers a potential new approach for treating insomnia by helping users fall asleep faster in relaxing virtual environments.

3. Challenges and Limitations:

   • The physical discomfort of current VR devices (e.g., the weight and heat of head-mounted displays) is a major challenge.
   • Laser tracking struggles to penetrate blankets, leading to suboptimal full-body tracking during sleep.
   • Lack of automatic adjustments for virtual world brightness and sound effects; blue light may interfere with sleep quality.
   • Public sleeping spaces are vulnerable to disruptions by "griefers," with insufficient sensory protection mechanisms.

4. Experimental or Evaluation Results:

   • Most users reported that the benefits of VR (e.g., faster sleep onset and social intimacy) outweighed the physical discomfort of the hardware.
   • Some users noted negative effects, such as visual strain and nasal discomfort.

5. Future Directions:

   • Improve VR hardware design to reduce headset weight and enhance ventilation.
   • Develop global control features for adjustable environmental parameters (e.g., automatic screen dimming or soothing sound effects).
   • Explore better support for coexistence of minors and adults in shared spaces, addressing potential ethical concerns.
   • Expand research to understand the impact of VR sleep on novice users or its potential applications in therapeutic contexts.

This study provides valuable insights for the future development of VR, sleep-assistive technologies, and digital social behaviors, while revealing new dimensions of technology's role in personal experiences and social interactions.
