BBeep: A Sonic Collision Avoidance System for Blind Travellers and Nearby Pedestrians
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 Best Citizen. BBeep triggers notifications by tracking pedestrians, predicting their future position in real-time, and provides sound notifications only when it anticipates a future collision Download the php bulletin board. 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 bat 파일 다운로드. 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 모털엔진 자막 다운로드. We observed that the proposed system significantly reduces the number of imminent collisions.
