A smartphone gps receiver can also use the known locations of phone cell towers and regularly updated maps of wi fi radio hotspots to improve accuracy.
Gps and gsm based guiding system for blind person.
If the person wants to give some instruction to the blind person he can send any of predefined sms and corresponding tone will be generated there.
This eta is fixed to the stick of the blind people.
In the kit guiding system for blind person based on gps gsm there is a gps receiver attached with the microcontroller will keep sending its current position to the microcontroller.
Stand alone gps devices usually have map and points of interest poi data preloaded onto the device.
If the person wants to give some instructions to the blind person he can send any predefined sms and the corresponding tone will be generated there.
Here we used gsm gps microcontroller which are the main essentials of the project.
This complete setup will be fixed to stick.
The term blindness refers to the people who have no vision at all or people who have less vision.
In the kit guiding system for blind person based on gps gsm there is a gps receiver attached with the microcontroller will keep sending its current position to the microcontroller.
Most of the blind people take support from guide dogs to walk.
The blind person will give the destination s name as the input to voice recognition module.
The global positioning system gps and global system for mobile communications gsm are interfaced to the microcon troller to detect the blind person location the proposed archi tecture consists of a gps signal receiver and gsm vibratory circuitry connected to arm7.
We are explaining about the gps and voice navigation system for blind people.
Gps global positioning system based voice navigation system for blind people.
This system is intended to provide overall measures รข object detection and real time assistance via global positioning system gps the system consist of ultrasonic sensor gps module gsm module and vibratory circuit speakers or head phones.
This system helps the blind person to navigate.
The location of the blind is found using global system for mobile communications gsm and global position system gps.
A stand alone device usually uses gps exclusively to calculate your position.
In the guiding system for a blind person based on gps gsm there is a gps receiver attached with the microcontroller that will keep sending its current position to the microcontroller.
In this paper we have presented the design of the voice based navigation system for blind using voice recognition module and gps module implemented on arduino board.
If the person wants to give some instruction to the blind person he can send any of predefined sms and corresponding tone will be generated there.
