BBeep: A Sonic Collision Avoidance System for Blind Travellers and Nearby Pedestrians

早稲田大学 小野梓記念学術賞

We present an assistive suitcase system, BBeep, for supporting blind people when walking through crowded environments. BBeep uses pre-emptive sound notifications to help clear a path by alerting both the user and nearby pedestrians about the potential risk of collision Download Tom Goldrun. BBeep triggers notifications by tracking pedestrians, predicting their future position in real-time, and provides sound notifications only when it anticipates a future collision 구글 어스 이미지 다운로드. We investigate how different types and timings of sound affect nearby pedestrian behavior. In our experiments, we found that sound emission timing has a significant impact on nearby pedestrian trajectories when compared to different sound types Download multiple classes. Based on these findings, we performed a real-world user study at an international airport, where blind participants navigated with the suitcase in crowded areas Download the Kakao Taxi app. We observed that the proposed system significantly reduces the number of imminent collisions.
