The document describes a navigational shoe system for blind persons. The proposed system uses vibration motors in shoes connected to a microcontroller and Bluetooth module. An Android app and the blind person's mobile phone GPS would provide location coordinates to the microcontroller. The microcontroller would then vibrate the motors in the shoes to guide the blind person along the route from their starting point to their destination. This navigation system is intended to help blind persons travel independently without needing to refer to sign boards for route information.

1. Navigational shoes
for Blind Person

2. Introduction :-
The main aim of this project is to implement a real time system for a
Blind Person to navigate them route to destination.
In existing system Blind Person need to look around to sign boards
for the information about the route he wants to travel.

3. Proposed System :-
 In our proposed system we design a shoe that navigates the route from source to destination.
Since the system is implemented in shoes we used a battery for power supply. Bluetooth is used
to get the location coordinate from mobile phone by using GPS setting from mobile. Need an
android app for searching the route destination to source route. Our control unit gives vibration
according to the route coordinates in shoes to indicate Blind Person. So the Blind Person moves
in the direction of the vibration.

5. Description of Block Diagram :-
3.1.1 Micro Vibrator motors: -
It vibrates on receiving the signal. Diameter of motor is 10mm. Voltage range is 3V-4.5V.
3.1.2 Bluetooth :-
It provides connectionless service between app and vibrators. We are using HC05 module for
our project. Frequency of this module is 2.4 GHz .Class 2 Bluetooth module with serial port profile.
3.1.3 Android App :-
It gives navigation from source to destination
3.1.4 Microcontroller :-
It is the heart of our system. We are using PIC18f4520 microcontroller. It is enhanced flash
microcontroller with 10 bit ADC and Nano watt technology.

6. Hardware & Softwares Required :-
 Hardware:
Micro vibrator motors, Bluetooth Module, LCD module, PIC
microcontroller.
 Softwares:
 ECLIPSE,(java)
 Google map libraries
 MPLAB
 Proteus
 DIP trace(Designing)

7. Technologies :-
GPS:
The Global Positioning System (GPS) is a satellite-based navigation system
made up of a network of 24 satellites placed into orbit by the U.S. Department of
Defence. GPS transmit data, which can be used to identify precise location on
earth by calculating the distance from various satellites. GPS can be used to get
longitude, latitude, altitude, speed and precise timing information.
Bluetooth:
Bluetooth is the international standard of wireless communication. It uses
microwave frequency of about 2.4GHz. Bluetooth technology is optimized for
use with WPANs and mobile. Bluetooth technology uses FHSS as a way to deal
with undesired interference.

8. Study of Android Basic :-
2.1 Technology we will use in android app are:
2.1.1 XML
-XML is used for designing UI.
-It consists of markup language with drag and drop facility.
- In this we are going to use different layouts such as Relative, Linear, Fragment etc.
2.1.2 Java:
-Java is used for controlling the events and internal processing of application.
- The database connectivity is done using the Java.
2.1.3 Google play service APIs:
-This is used for accessing the google services.
-This provides the set of libraries which we are going to import into Java.
-We will visit the Google developer console site for getting Google API keys.

9. 2.2 For developing an android app we are going to install :
2.1.1 XML
ADT plugins into eclipse IDE .This will provide us different API levels.
2.3 For installing ADT plugins steps are:
- Open eclipse -> go to windows -> install new software
- Enter the URL of android studio->click on install button.
- This will show us android AVD manager and android package manager.
- We can install the API’s using android package manager.

16. Conclusion :-
 We design a shoe that navigates the route from source to destination. Since the
system is implemented in shoes, we use a battery for power supply. Bluetooth is
used to get the location coordinate from mobile phone by using GPS setting from
mobile. Need an android app for searching the route destination to source route. Our
control unit gives vibration according to the route coordinates in shoes to indicate
Blind Person. So the Blind Person moves in the direction of the vibration. System will
have low cost, low power consumption, and high accuracy
 Future scope of this project is, we can add pressure sensors to count
number of steps and speed in addition to navigation.
 We can calculate the distance travelled.
Future Scope & Application:-

17. Application :-
 While driving, it helps the person to navigate with the directions via vibrations.
 Mainly used for navigation purpose.
