Abstract: The aim of the project is to enable the visually impaired people to smoothly navigate with the help of buzzers. Ultrasonic Navigation for Visually Impaired is the multidisciplinary project with computer science, electronics engineering and health science which helps the blind people to navigate with speed and confidence by detecting the nearby obstacles using the help of ultrasonic waves and notify them with a buzzer sound. It allows visually impaired individuals to travel through familiar and unfamiliar environments without the assistance of guides or a stick. One of the main peculiarities of this device is that it will be affordable. It will be equipped with ultrasonic sensors, consisting of a module. Using the sensor, visually impaired can detect the objects around them and can travel easily. When the sensor detects any object, it will notify the user by a beep sound. The device also contains a heartbeat sensor which keeps a track of the blind person’s heartbeat. In case the heartbeat crosses the threshold value, the caretakers will be notified with an SMS on their phone about the person’s location. The caretakers can also receive a notification about the person’s location and can track them if required using an android application. The android application also lets the blind person to receive the messages on his/her phone in the form of audio. This is an automated device. Thus, this device will be of a great use for the blinds and help them travel different places.
