Özet: This paper presents a micro-controller based ultrasonic system developed to help the blind person navigate in closed spaces and be in contact with nearby traffic lights by sensing them and sending a signal for the traffic light to change to red signal. The system consists of two related but independent systems. The first one is a specially designed helmet with ultrasonic sensors which is equipped with RF circuit, and the second is a hand tool again equipped with ultrasonic sensors. The sensors are in the form of ultrasonic transmitters and receivers, and are configured to measure the distance to obstacles in-front of the sensor pair. The paper describes the design and testing of the system with blind people.
