Paper Information

• Research Domain: Human-Computer Interaction and Robotics, focusing on assistive technologies and navigation for visually impaired individuals
• Keywords: Accessibility, collaborative robots, human-computer interaction, guide dog robots, user needs study, personalized design, qualitative analysis, guide dog training, artificial intelligence, perception systems

Research Background and Problem Statement

• Identified Problems or Challenges:

  • Currently, only a small percentage of blind or visually impaired individuals have access to guide dogs due to limited resources and high maintenance costs.
  • Guide dogs face limitations in understanding complex environmental information, human instructions, and adapting to new or changing environments.
  • Although the demand for robotic guide dogs is rising, existing research lacks user-centered design benchmarks and fails to fully consider actual user needs and interaction characteristics in real-world scenarios.

• Significance:

  • With the increasing global population of blind and visually impaired individuals, providing effective and safe navigation assistive devices has become a pressing need.
  • Robotic guide dogs have the potential to address the scarcity of guide dog resources and overcome the limitations of current mobility assistive devices.

• Research Motivation and Related Work:

  • Current robotic guide dog studies primarily focus on technological development, with limited emphasis on user experience and practical usage needs.
  • This study aims to extract core interaction characteristics between guide dogs and users through user research, providing design insights for robotic guide dog development.

Solution

• Proposed Method or Solution:

  • Employing a user-centered research approach, conducting semi-structured interviews and observational studies with 23 guide dog users and 5 professional trainers to identify core attributes and limitations in guide dog-user interactions.
  • Utilizing qualitative analysis to extract user requirements suitable for robotic guide dog design, including hardware, perception capabilities, and interaction interface design.

• Innovative Contributions:

  • For the first time, proposing user research-based design guidelines for robotic guide dogs, revealing the need for flexible perception and refined personalization capabilities in robotic guide dogs.
  • Integrating the evolving interaction characteristics between guide dogs and users into robotic design, a topic not sufficiently explored in existing robotics literature.

• Implementation Steps and Key Technologies:

  • The study design includes detailed interview procedures and field observations to collect interaction data in real environments.
  • Data is processed using thematic analysis to generate patterns and themes of user requirements.
  • Specific design recommendations for robotic guide dogs are proposed, including body design, human-computer interaction interfaces, sensor technologies, and battery energy requirements.

Research Outcomes

• Specific Findings:

  • Identified three major limitations in current guide dog-user interactions: insufficient environmental perception by guide dogs, restricted one-way communication, and low adaptability in unfamiliar environments.
  • Highlighted the importance of personalized training for guide dogs to match user needs, a characteristic critical for robotic guide dog design.
  • Gathered user and trainer expectations and concerns regarding robotic guide dogs, such as the need for trust-building, personalized adaptation features, and whether robots can compensate for the emotional support provided by guide dogs.

• Advantages Compared to Existing Solutions:

  • A more user-centered design approach, introducing robotic guide dog design concepts based on long-term interaction and personalized needs.
  • Practical technical suggestions for using multimodal sensors to reduce visual blind spots and improve environmental perception capabilities.

• Experimental or Evaluation Results:

  • User feedback indicates overall optimism about robotic guide dogs and acknowledges their potential advantages in navigation, safety assurance, and environmental adaptability.
  • Design guidelines derived from qualitative research significantly address the shortcomings of existing robotic designs in neglecting user interaction and trust-building.

• Limitations and Future Directions:

  • User studies based on robotic guide dog experiences have not yet been conducted; current findings are limited to the expectations of guide dog users.
  • Future work should integrate perspectives from technology developers and validate design solutions through user field experiments.
  • Explore methods for personalization and trust-building to address acceptance issues when robotic guide dogs replace human-animal relationships.
