盲人与导航机器人互动后，逐渐形成何时依赖、何时自主的判断。
How Does Delegation in Social Interaction Evolve Over Time? Navigation with a Robot for Blind People
- 六名盲人用户在真实博物馆中反复使用导航机器人
- 随时间推移，用户更明确区分何时该依赖机器人或独立行动
- 研究揭示人机协作策略随交互演化，适合设计自适应机器人
自主与独立导航对日常生活至关重要，但对视障人士仍具挑战。机器人系统可通过智能导航辅助提升移动能力与信心。然而，完全自主系统可能削弱用户的控制感，即使他们希望保持主动参与。尽管人机协作的重要性已被认可，但关于用户对协作关系感知如何随重复使用变化的研究仍较少。本研究通过六名视障参与者在真实博物馆环境中与导航辅助机器人进行多次交互，完成穿越人群、靠近队列及避障等任务。结果显示，参与者随时间推移优化了自身策略，逐步形成对何时依赖机器人、何时自主行动的清晰偏好。该工作为理解人机协作策略的动态演化提供了洞见，并为能随用户需求自适应的机器人设计提供指导。
原文摘要 · Abstract (English)
Autonomy and independent navigation are vital to daily life but remain challenging for individuals with blindness. Robotic systems can enhance mobility and confidence by providing intelligent navigation assistance. However, fully autonomous systems may reduce users' sense of control, even when they wish to remain actively involved. Although collaboration between user and robot has been recognized as important, little is known about how perceptions of this relationship change with repeated use. We present a repeated exposure study with six blind participants who interacted with a navigation-assistive robot in a real-world museum. Participants completed tasks such as navigating crowds, approaching lines, and encountering obstacles. Findings show that participants refined their strategies over time, developing clearer preferences about when to rely on the robot versus act independently. This work provides insights into how strategies and preferences evolve with repeated interaction and offers design implications for robots that adapt to user needs over time.
