ABSTRACT
The aim of this project is to construct a digital assistant for blind people that assist them during travel. Micro controller based voice alert system for blind with GPS is designed to get alerts for few places. It is a micro controller based device, which intellectually finds the location in which it was currently located and gives the alert to the blind man if it was his destination area.
GPS is the acronym for Global Positioning System. It is employed to find the position where the user is located on the earth. This information is provided by the GPS with the help of the data it receives from the satellites.
Microcontroller is the heart of the device. It stores the data of the current location which it receives from the GPS system. So that it can make use of the data stored to compare with the destination location of the user. By this it can trace out the distance from the destination and produce an alarm to alert the user in advance. This device helps the blind people in their journeys. It helps him to get the alerts regarding the arrival of his destination before few minutes.
This device is designed to provide with a greater advantage producing voice based announcement for the user i.e. the user gets the voice, which pronounces his destination location as and when it is about to reach the destination. Here instead of the alerting sound the user can directly here the location recorded by the user itself.
