Wearable Navigation for Blind People

Abstract

ABSTRACT- To help the visually impaired and blind people walk to the destination efficiently and safely in indoor & outdoor environment, a wearable navigation device is developed in this project. The main components of the system are a microcontroller, various sensor, IOT modules. The locating, way-finding, route following and obstacle avoiding modules are the essential components in a navigation system.  A set of sensors used to track the path and alert the user of obstacles in front of them. The user is alerted by a sound emitted through a voice processor. Vibration on the wrist, which is helpful when the user has hearing loss or is in a noisy environment. In addition, the system alerts people in the surroundings when the user stumbles over or requires assistance, and the alert, along with the system location is sent as a phone message to registered mobile phone of family members and caregivers. The proposed system has more features than other similar system. And it is very useful tool to improve the quality of life.
