The purpose of this project is to provide the self-assistance for the visually impaired persons. In case of blind people fall in a critical position, the sensor network connected with microcontroller will senses the situation and passes the information to the caretakers. In this paper we proposed that GPS and GSM based navigation system for blind people with a Braille capacitive touch keypad. The reason behind choosing the Braille keypad is that blind people can’t see the key digits, for that they need a touchable interface, with some symbols they will remember the input instructions on capacitive touch keypad. The navigation system consists of GPS for location finding along with wireless sensor nodes such as temperature sensor, ultrasonic sensor and accelerometer sensor. These sensors will be useful for monitoring the surrounding situations. Additionally we have a device control section which will be operated by using Braille touch keypad, the device control section of a microcontroller connected with the load devices as per our need. The AC devices such as bulbs, fans can be controlled to the controller through a relay.
