Document Title

User Onboarding in Virtual Reality: An Investigation of Current Practices.

Document Information

• Subject Area: User onboarding and instructional design in virtual reality.
• Keywords: Virtual reality, user onboarding, learning, human assistance, computer-aided.

Research Background and Issues

• Identified Problems or Challenges:

  • Beginners face difficulties in learning operations within immersive virtual reality (VR) applications, especially due to a lack of experience with hardware devices and interaction modes.
  • VR applications lack unified interaction standards, such as variations in object-grabbing button operations across different applications.
  • User onboarding techniques in VR systems remain fragmented, lacking a standardized optimization framework.

• Research Significance:

  • The increasing popularity of virtual reality devices, especially among public users, highlights the importance of onboarding processes.
  • Ineffective onboarding may limit users' understanding and adoption of VR systems, reducing usage efficiency.

• Related Work:

  • Existing research on software user onboarding includes two methods: tutorial-based automated onboarding and instructor-based manual guidance. The practical effectiveness of these methods in VR contexts requires further analysis.
  • Specific onboarding techniques in VR (e.g., animations, text instructions, spatial cues) have shown exploratory progress but still face design blind spots, such as insufficient feedback and adaptive design, as well as limited support for non-verbal communication.

Proposed Solution

• Proposed Method:

  • Analyze the advantages and disadvantages of current VR onboarding methods through a literature review, evaluation of 21 VR tutorials, and semi-structured interviews with 15 experienced VR experts to construct a conceptual framework for VR user onboarding.
  • Propose a series of design dimensions, such as contextual relevance, flexibility, interactivity, and feedback mechanisms, and identify key design parameters.

• Innovations:

  • Developed a multidimensional conceptual framework covering various onboarding methods, from tutorial-based guidance to instructor-assisted onboarding, incorporating design context as a core analytical perspective.
  • Systematically analyzed the complementarity of instructor-assisted and automated tutorial-based onboarding methods, while proposing future optimization directions based on specific scenarios.

• Implementation Steps and Techniques:

  1. Design and conduct tutorial reviews based on heuristic evaluation methods, adopting evaluation standards suitable for virtual environments.
  2. Collect and analyze common issues and current solutions in practical onboarding work through semi-structured interviews with VR experts.
  3. Summarize findings from collaborative interviews and theoretical research to design the conceptual framework and list key future research directions.

Research Outcomes

• Specific Outcomes:

  • Defined a framework for VR user onboarding, encompassing eight major dimensions (e.g., coverage, interactivity, feedback mechanisms, instruction formats), providing references for analyzing and designing VR onboarding methods.
  • Completed heuristic evaluations of 21 VR tutorials, revealing three major challenges in current VR instructional tutorials: understandability, feedback and feedforward, adaptability, and accessibility.
  • Identified specific needs for VR onboarding through expert interviews, such as supporting visual mirroring for human instructors and mechanisms for non-verbal communication.

• Comparison with Existing Solutions:

  • More comprehensively covers the current state and challenges of VR onboarding, addressing the limitations of single tutorial analysis or instructor interviews in generalization and application levels.
  • Emphasized the complementarity of automated tutorials and instructor-assisted modes, proposing directions for better integration of the two.

• Experimental or Evaluation Results:

  • Tutorial evaluation results indicate that most tutorials perform well in intuitiveness (e.g., clarity of instruction placement, balance of quantity) but show significant shortcomings in providing fine-grained feedback and assisting user behavior.
  • Interview analysis revealed challenges faced by instructors, such as device adaptation issues, lack of virtual scene awareness, and optimization space for instruction delivery efficiency.

• Limitations and Future Directions:

  • Limitations: Current tutorial evaluation sample size is limited, and most interview participants come from academic backgrounds, lacking comprehensive feedback from industrial application scenarios.
  • Future Directions:
    1. Design more flexible and adaptable tutorial systems, such as dynamically adjusting instruction difficulty and coverage.
    2. Develop tools to support rapid customization and optimization of onboarding tutorials, such as generating dynamic tutorials through recorded real demonstrations.
    3. Enhance communication tools between instructors and learners, such as immersive onboarding systems supporting non-verbal communication.
