• Research Domain: Remote Collaboration, Human-Computer Interaction, and Drone Technology
• Keywords: Drone, User Interface, Remote-Controlled Aircraft, Remote Collaboration, Telepresence, Collaborative Work, Quadcopter, Remote Collaboration Control

Research Background and Problem Statement

• Identified Problems or Challenges:

  • Current drone technologies have limitations in supporting real-time collaboration and social interaction among multiple remote users.
  • Existing remote drone operations often require assistance from on-site users, lacking the freedom for multiple users to independently control and manage drones.
  • Hardware constraints, such as noise and limited field of view, hinder the development of drone telepresence systems.

• Significance:

  • Drones have immense potential in scenarios such as humanitarian crises, search and rescue missions, and aerial surveys, reducing risks, improving efficiency, and expanding access to hard-to-reach areas.
  • Remote drone systems that support multi-user real-time collaboration can enhance decision-making processes and improve team situational awareness.

• Research Motivation and Related Work:

  • The motivation is to develop a drone remote control system that supports mid-air remote collaboration. Traditional drone platforms, such as experimental drones by Google or existing remote video platforms, fail to adequately address these issues.
  • Rae et al.'s telepresence design framework provides the theoretical foundation for this study. By evaluating previous research, the authors identified the need to address multi-user synchronized drone control issues across both software and hardware domains.

Proposed Solution

• Proposed Approach:

  • Development of the "Squadrone" system, an aerial telepresence drone platform supporting real-time collaboration among multiple remote users.
  • Key features include shared 360-degree views, multi-user control switching, integration of virtual reality technologies, and user-friendly interface design.

• Innovations:

  • Supports multiple users connecting to the drone simultaneously, allowing independent adjustment of viewpoints without interfering with others.
  • Provides users with the ability to share flight operations, utilizing game controllers for intuitive control.
  • Offers an immersive experience through high-resolution 360-degree cameras and real-time audio streaming.

• Implementation Steps and Key Technologies:

  1. Adopted a human-computer interaction design approach, developing Squadrone through three design iterations.
  2. Technological implementation combined game controller APIs, WebRTC video streaming, cloud interfaces, and drone control modules.
  3. Developed a web-based user interface compatible with drones for real-time management, control, and task customization.
  4. Conducted hardware modifications, such as adding anti-vibration damping pads to reduce the impact of vibrations on camera quality.

Research Outcomes

• Specific Outcomes:

  • The Squadrone system successfully supports multi-user remote collaboration, providing shared aerial views and real-time communication capabilities.
  • Participants reported improved awareness of remote environments through the platform and successfully completed collaborative tasks, such as aerial exploration and object localization.

• Advantages:

  • Compared to existing solutions, Squadrone offers enhanced immersion and user experience, particularly in terms of drone control flexibility and 360-degree view support.
  • In experiments, Squadrone's design improved team members' engagement and efficiency.

• Experimental and Evaluation Results:

  • Data was collected from 13 participants (aged 19-32) over three design iterations, with a total flight time of approximately 380 minutes.
  • Participants expressed overall satisfaction with the platform's immersive features and collaborative experience, with an average score exceeding 6.16/7 (based on an immersion questionnaire).
  • In multi-user scenarios, team engagement and task contributions were relatively balanced.

• Limitations and Future Directions:

  • Limitations:
    • Drone flight time is constrained by battery life, and audio capture quality depends on the physical position of the drone operator.
    • Users may experience an initial adaptation period to devices such as VR headsets, which could impact early usage experiences.
  • Future Directions:
    • Further research on the collaborative benefits of multi-user remote control switching and visual focus.
    • Optimization of user interfaces and information display methods (e.g., HUD) to accommodate complex task scenarios.
    • Exploration of more efficient noise suppression methods and drone audio capture technologies.
