Mood Worlds: A Virtual Environment for Autonomous Emotional Expression

Paper Information

• Field: Application of virtual reality technology in enhancing mental health and well-being
• Keywords: Virtual reality, well-being, emotional expression, emotion regulation, positive technology, immersive interaction

Research Background and Problem

• Identified Issues or Challenges: While virtual reality (VR) holds significant potential for promoting positive emotions and psychological health interventions, existing research primarily focuses on pre-designed environments for emotion induction, offering limited user autonomy and customization. Most applications rely on predefined scenarios to alter user experiences, lacking in-depth exploration of user-driven virtual environment creation.
• Importance: Mental health and well-being are crucial for societal and individual efficiency. Providing autonomy and personalized design methods can better meet the needs for emotional expression and regulation, fostering positive psychological experiences.
• Research Motivation and Related Work: Current studies on emotion induction and positive technology often focus on singular factors such as color or environmental impact, without adequately integrating the potential therapeutic effects of user-driven creation on emotion regulation.

Solution

• Methods and Solutions:

  1. Develop a virtual reality application named "Mood Worlds," enabling users to autonomously create virtual environments to express emotions.
  2. Provide various tools and options, including brushes, predefined 3D objects, panels for controlling environmental lighting and colors, among others.
  3. Apply an emotion induction method based on the Affective Emotion Memory Task (AEMT) to enhance the emotional expression experience.

• Innovations:

  1. Propose, for the first time, a solution allowing users to autonomously design virtual environments for emotional expression.
  2. Integrate principles of emotional psychology and design requirements, making the creation process not only passive but also an active emotion induction method.
  3. Combine color psychology and dynamic animation technology to enhance users' visual experience and emotional engagement.

• Implementation Steps and Key Technologies:

  1. Preliminary study: Simulate environments for users to express emotions and collect design requirements.
  2. Application development: Extend functionalities based on the Open Brush platform, designing diverse customization tools and environments.
  3. User study: Conduct usability tests with 16 participants, including surveys and semi-structured interviews, to evaluate emotional enhancement effects.

Research Outcomes

• Specific Results:

  1. Quantitative evaluation (PANAS questionnaire) indicates a significant increase in positive emotions after using Mood Worlds.
  2. Mood Worlds supports users in expressing multidimensional emotions, enhancing well-being and emotional engagement.
  3. Insights into personalized design effects and sensory interaction experiences were obtained, providing direction for future VR positive technology design.

• Advantages:

  1. Mood Worlds allows users to design environments based on personal emotions rather than relying on predefined scenarios.
  2. By integrating dynamic animation and sensory elements, it offers a more immersive emotional expression experience.
  3. Incorporating psychological models (e.g., PERMA theory) has created a comprehensive framework for supporting well-being.

• Experimental or Evaluation Results:

  1. PANAS data shows a significant increase in positive emotions (from 20.2 points to 33.7 points).
  2. Participants expressed in interviews that the experience met their expectations, providing a sense of autonomy and satisfaction in creation.
  3. All participants had a positive experience with Mood Worlds and perceived it as highly valuable.

• Limitations and Future Directions:

  1. The current study focuses primarily on short-term emotional enhancement effects, without exploring long-term impacts. Future research should conduct longitudinal studies to assess long-term efficacy.
  2. This study only addresses positive emotional expression; future work could explore its effectiveness in managing negative emotions.
  3. Investigate the potential enhancement of social relationships through shared multi-user scene design.
  4. Integrate olfactory and gustatory interaction technologies to enrich sensory experiences.

Mood Worlds provides users with new possibilities for expressing and regulating emotions through autonomous construction of immersive environments. By combining perception, psychology, and technological practices, it offers a robust reference for the design and application of future VR positive technologies.
