Bibliographic Information

• Research Areas: Augmented Reality (AR), Human-Computer Interaction (HCI), and Collaboration Studies
• Keywords: Literature Review, Social Presence, Augmented Reality, Head-Mounted Displays, User Studies, Collaboration, Presence Questionnaire

Research Background and Issues

• Issues and Challenges:

  1. Social presence is widely used as a quality metric for assessing the role of augmented reality (AR) in supporting collaboration. However, existing literature presents conflicting findings regarding how social presence affects collaboration quality.
  2. Some studies suggest that high social presence enhances collaboration quality, while others find no significant relationship or even negative impacts.
  3. Due to differences in usage scenarios and technical characteristics between virtual reality (VR) and augmented reality (AR), findings about social presence in VR cannot be directly applied to AR.

• Significance:

  • Understanding the role of social presence in collaboration can provide support for designing more effective AR tools.
  • In the field of augmented reality, especially in remote support and interactive collaboration scenarios, clarifying the role of social presence is crucial for improving user experience and optimizing systems.

• Research Motivation:

  • The exact role of social presence in AR collaboration remains unclear, particularly in scenarios involving head-mounted displays (HMDs). There is a lack of systematic literature reviews in this area.

Solution

• Method:

  • The authors conducted a literature review, collecting and analyzing empirical studies on social presence and AR collaboration.
  • Through rigorous screening across multiple literature databases, 19 relevant research articles were selected for in-depth analysis.
  • The selected studies were summarized and analyzed across multiple dimensions, including research methods, scenario design, device usage, and measurement metrics.

• Innovative Contributions:

  • This is the first systematic literature analysis focused on social presence in AR head-mounted display research.
  • Based on the exploration of social presence dimensions in AR collaboration, the authors proposed design recommendations and identified current research gaps and future directions.

• Implementation Steps:

  1. Define the scope of literature collection and search keywords, selecting studies published after 2012.
  2. Apply clear screening criteria to select relevant literature.
  3. Conduct detailed analysis of the selected studies based on scenario design, collaboration types, participant backgrounds, social presence measurement methods, and other factors.

Research Findings

• Specific Findings:

  1. Mechanisms of Social Presence:

     • Identified interventions that enhance social presence, such as gaze cues, virtual avatars, and immersive cues.
     • High social presence generally improves user preference and interaction experiences, but its impact on task completion time and cognitive load varies by context.
     • In asymmetric collaboration (Task Asymmetry), social presence is often positively correlated with other metrics such as task completion time and usability.

  2. Effects of Interventions:

     • Humanized virtual avatars (e.g., scalable avatars) in augmented reality significantly enhance social presence in most scenarios.
     • Task type and scenario greatly influence the effects of social presence: symmetric collaboration scenarios show less benefit, while asymmetric tasks exhibit significant impacts.

  3. Measurement Methods and Metrics:

     • Commonly used questionnaire tools include the "Social Presence Questionnaire" and "Networked Minds Measure," but the authors noted that relying solely on self-reports may be insufficient. Behavioral analysis or physiological data should be incorporated.

  4. User Preferences:

     • Users generally prefer designs that enhance social presence, particularly in remote support tasks.

• Comparison with Existing Research:

  • Compared to findings in virtual reality (VR) research, augmented reality emphasizes the integration of real and virtual elements in task environments, which is the root of the complexity of social presence in AR.

• Experimental/Evaluation Results:

  • In most settings, scenarios with high social presence received higher preference ratings from participants, though improvements in task completion time or cognitive load were not universally observed.
  • Specially designed interventions, such as virtual avatars simulating real behaviors, effectively enhanced social presence.

• Limitations and Future Directions:

  • Limitations:

    1. The literature review was based on specific screening criteria, potentially overlooking contributions from non-English studies.
    2. Most experiments did not explicitly reveal causal relationships between social presence and collaboration quality, only showing correlations between co-occurring metrics.

  • Future Directions:

    1. Expand measurement methods for social presence by combining questionnaires, autonomous behavioral observations, and physiological data to improve external validity.
    2. Explore the application value of mini and life-sized avatars in complex symmetric collaboration scenarios.
    3. Develop more realistic interventions that elicit natural responses to more effectively enhance AR collaboration experiences.
