Visually impaired people face unique challenges in their day to day life while navigating in unfamiliar public locations. Using a walking stick relies on trial and error, particularly in unfamiliar locations. Also from a walking stick the user can only identify obstacles which are touching the stick and cannot identify the obstacles which are above his waist height. Electronic Travel Aids (ETAs) are devices that use sensor technology to assist and improve the blind user’s mobility in terms of safety. In this context, we implement a system whose objective is to give blind users the ability to move around in unfamiliar environment, whether indoor or outdoor, through an interface specifically designed to cater the visual imperfections. In this blind people issues the commands and then receive the response using audio signals. GPS receiver is used to receive the values of the latitude and longitude continuously. With the advancement in technology usage of voice recognition is easier to send commands regarding directions to the blind people. As an application of this GPS technology here GPS based voice alert system for the blind persons are explained practically in subsequent paragraphs.
