用移动机器人辅助视障者参与混合视觉群体导览。
Robot-Assisted Group Tours for Blind People
- 设计机器人系统支持视障者在导览中导航与互动。
- 8名视障者参与实地测试，普遍感到安全且希望获取环境信息。
- 适合关注无障碍交互与智能导览的开发者与设计师。
群体互动对社会功能至关重要，但有效参与依赖于识别和解读视觉线索，这对视障人士构成重大挑战。本文研究移动机器人如何支持视障者参与群体活动。基于对5名视障者和5名博物馆专家的访谈，设计并原型化了一套支持视障者参与导览的机器人系统。在科技馆开展实地研究，每名视障参与者（n=8）与一名导游及两名视障者共同参与导览（共8组）。结果表明，机器人导航支持提升了用户的安全感，但在群体参与中仍存在顾虑，并体现出对环境信息获取的偏好。研究提出未来助盲机器人系统的设计启示。
原文摘要 · Abstract (English)
Group interactions are essential to social functioning, yet effective engagement relies on the ability to recognize and interpret visual cues, making such engagement a significant challenge for blind people. In this paper, we investigate how a mobile robot can support group interactions for blind people. We used the scenario of a guided tour with mixed-visual groups involving blind and sighted visitors. Based on insights from an interview study with blind people (n=5) and museum experts (n=5), we designed and prototyped a robotic system that supported blind visitors to join group tours. We conducted a field study in a science museum where each blind participant (n=8) joined a group tour with one guide and two sighted participants (n=8). Findings indicated users' sense of safety from the robot's navigational support, concerns in the group participation, and preferences for obtaining environmental information. We present design implications for future robotic systems to support blind people's mixed-visual group participation.
