This document describes a guide cane mobile application that aims to help visually impaired people navigate and communicate more easily. The application would allow blind users to locate nearby buses, get directions, make phone calls, read messages, check their location and battery level using text-to-speech and speech-to-text features. It follows a typical project structure, outlining objectives, existing systems and their disadvantages, the proposed system, advantages, system specifications, implementation details, use case diagrams, sequence diagrams, class diagrams and data flow diagrams. The goal is to provide blind individuals with independence and privacy by allowing independent use of their mobile devices.

3. INTRODUCTION
 Now a days e-commerce application development is at most demand
due to its unique features and compatible services.
 GUIDE CANE helps visually impaired people to access all kinds of information
easily.
 GUIDE CANE is a navigation guidance that helps blind user to interact with
their devices more easily.
 This App adds audible feedback to user’s device.

4. INTRODUCTION (cont..)
 Features of this App includes Call making, Message reading(inbox &
outbox),Check battery percentage, Location access, Finding route of near by
bus, Locating a remote bus etc..
 It includes both speech to text and text to speech conversion feature.
 Those who have installed our application will be able to track the route and
location of any bus, thus our application provides a complete communication
and a navigation assistance to blind person.

5. OBJECTIVE
 Usually Smart Phones and tablets may not be useful to blind people.
 But by implementing this App appropriately will make this as a boon to Blind
person.
 For example people with vision problem can use voice commands in Smart
Phones to make a call, read messages from inbox and outbox etc.
 This has features for navigation and communication.

6. OBJECTIVE (cont..)
Navigation features
 Finding route of nearby bus
 Locating a remote bus
 Getting current location of blind person etc..
Communication features
 Calling from contact list
 Reading out messages

7. EXISTING SYSTEM
 At present there is no application for better navigation of a blind person.
 In case of navigation they can’t access nearby buses, current location of a bus
etc.
 Now they have to depend others to know their current location.
 For knowing Day, Date, time they have to interact with others

8. EXISTING SYSTEM DISADVANTAGES
 Always seeking others help.
 Cannot interact with QWERTY keyboard easily, So text messaging is difficult.
 So our secrets have to be shared with others.
 No privacy.
 They can be cheated easily in many ways, for example while paying auto fare,
fake locations etc.

9. PROPOSED SYSTEM
 GUIDE CANE , which is built specifically to help blind users in navigation like
catching a bus, reading printed text and knowing their exact whereabouts in
unfamiliar areas.
 GUIDE CANE is also going to help in solving routine problems for blind people
so they can be more confident about navigating in the real world.
Application implemented by using
1. Location services
2. Text-to-speech/Speech-to-text services
3. JSON parsing

10. ADVANTAGES OF PROPOSED SYSTEM
 Can call to any number directly from the contacts or a number itself.
 Read messages in the inbox & outbox.
 Checking the current day, date and time.
 Find the current location updates and helps in navigation.
 Find battery level of the phone.
 Read bus route.

11. ADVANTAGES OF PROPOSED SYSTEM (cont..)
 Locate bus by using GPS.
 Get auto fare of travel using timer.
 Viewing 3D map view of places.
 View route map of two places.
 View route of particular day they travel.
 Add favorite places in map.
