---- PROTOTYPE ---------BBeep is a Sonic Collision Avoidance System consisting of a smart suitcase, coupled with a camera and the NavCog way-finding smartphone application designed help people with visual disabilities navigate airport terminals safely and independently. NavCog, uses Bluetooth technology to create a beacon system that helps users navigate their way through the airport terminal. The beacons help the app provide audio directions around the airport, which includes detailed instructions to restrooms, restaurants, gates and ticketing counters. The app is able to determine a user’s location with less than 1.5 meters (less than 5 feet) of error BBeep uses the pre-emptive sound notifications to help clear a path by alerting both the user and nearby pedestrians about the potential risk of collision. BBeep triggers notifications by tracking pedestrians, predicting their future position in real-time, and provides sound notifications only when it anticipates a future collision. A series of beeps begins five seconds before collision. The frequency of the beeps increases at 2.5 seconds. When collision is imminent, BBeep issues a stop sound, prompting the blind user to halt immediately.
