1. INTRODUCTION

1.1 OVERVIEW

The main purpose of the project is to develop an application called Non Visual

Search Engine for Visually Challenged is a need for web based application where we provide a

user friendly application for visually impaired people. This application works just like Google

search engine but with a new feature for visually challenged. The data entered anywhere on the

screen is taken into to a textbox with focus in it. So it gives all the results of it in a systematic

manner. When the user clicks the right mouse the first result is read heard. For next result, left

mouse is pressed. In this way the user can listen all the results of the required data.In the flexibility of the uses the interface has been developed a graphics concept in

mind, associated through a browses interface. The GUIS at the top level have been categorized

as Administrative user interface and the operational or generic user interface.

The administrative user interface concentrates on the consistent information that is

practically, part of the organizational activities and which needs proper authentication for the

data collection. The interfaces help the administrations with all the transactional states like Data

insertion, Data deletion and Date updation along with the extensive data search capabilities.

The operational or generic user interface helps the users upon the system in transactions

through the existing data and required services. The operational user interface also helps the

ordinary users in managing their own information helps the ordinary users in managing their

own information in a customized manner as per the assisted flexibilities.

2. ANALYSIS

2.1 EXISTING SYSTEM

The Word Wide Web has come to take an important part in our lives: it has become

indispensable for finding information, communicating with others, and performing daily tasks

for work, banking, and shopping. Web sites are designed mostly for graphical interaction,

limiting access for an entire community of people with visual disabilities. According to the

WHOs World Health Report, there are approximately 45 million people without sight

worldwide. These people dont have proper tool to get the information they want.

2.1.1 PROBLEMS IN THE EXISTING SYSTEM

Visually challenged people dont have proper tool to get the information they want

Fewer Users Friendly.

2.2 PROPOSED SYSTEM

A web based application is needed where we provide a user friendly application for

visually impaired people. This application works just like Google search engine but with a new

feature for visually challenged. The data entered anywhere on the screen is taken into to a

textbox with focus in it. So it gives all the results of it in a systematic manner. When the user

clicks the right mouse the first result is read heard. For next result, left mouse is pressed. In this

way the user can listen all the results of the required data.

3. IMPLEMENTATION

Implementation literally means to put into effect or to carryout. The system

implementation phase if the software deals with the translation of the design specifications into

the source code. The ultimate goal of the implementation is to write the source code and the

internal documentation so that it can be verified easily. The code and documentation should be

written in a manner that eases debugging, testing and modification. System flow charts, sample

run on packages, sample output etc., is part of the implementation.

An effort was made to satisfy the following goals in order

Clarity and simplicity of the code.

Minimization of hard coding.Minimization of the amount of memory used.

Through phased implementation we can use our proposed system

HARDWARE & SOFTWARE REQUIRMENTS

Requirement Specification plays an important role to create quality software solution;

Requirements are refined and analyzed to assess the clarity.

Requirements are represented in a manner that ultimately leads to successful software

implementation. Each requirement must be consistent with the overall objective. The

development of this project deals with the following requirements:

Hardware Requirements

Software Requirements

HARDWARE REQUIREMENTS:

The selection of hardware is very important in the existence and proper working of any

software. In the selection of hardware, the size and the capacity requirements are also

important.

4. TEST CASES

Testing is one of the most important phases in the software development activity. In

software development life cycle (SDLC), the main aim of testing process is the quality; thedeveloped software is tested against attaining the required functionality and performance.

During the testing process the software is worked with some particular test cases and

the output of the test cases are analyzed whether the software is working according to the

expectations or not.

The success of the testing process in determining the errors is mostly depends upon the

test case criteria, for testing any software we need to have a description of the expected

behavior of the system and method of determining whether the observed behavior confirmed to

the expected behavior.

LEVELS OF TESTING

Since the errors in the software can be injured at any stage. So, we have to carry out the

testing process at different levels during the development. The basic levels of testing are Unit,

Integration, System and Acceptance Testing.

The Unit Testing is carried out on coding. Here different modules are tested against the

specifications produced during design for the modules. In case of integration testing differenttested modules are combined into sub systems and tested in case of the system testing the full

software is tested and in the next level of testing the system is tested with user requirement

document prepared during SRS.

There are two basic approaches for testing. They are:

FUNCTIONAL TESTING

In Functional Testing test cases are decided solely on the basis of requirements of the

program or module and the internals of the program or modules are not considered for selection

of test cases. This is also called Black Box Testing

STRUCTURAL TESTING

In Structural Testing test cases are generated on actual code of the program or module

to be tested. This is called White Box Testing.


20/29

TESTING PROCESS

A number of activities must be performed for testing software. Testing starts with test

plan. Test plan identifies all testing related activities that need to be performed along with the

schedule and guide lines for testing. The plan also specifies the levels of testing that need to bedone, by identifying the different testing units. For each unit specified in the plan first the test

cases and reports are produced. These reports are analyzed.

TEST PLAN:

o Test plan is a general document for entire project, which defines the scope,

approach to be taken and the personal responsible for different activities of

testing. The inputs for forming test plans are

o

Project plano Requirements document

o System design

TEST CASE SPECIFICATION:

Although there is one test plan for entire project test cases have to be specified

separately for each test case. Test case specification gives for each item to be tested. All test

cases and outputs expected for those test cases.

TEST CASE EXECUTION AND ANALYSIS:

The steps to be performed for executing the test cases are specified in separate

document called test procedure specification. This document specify any specify

requirements that exist for setting the test environment and describes the methods and

formats for reporting the results of testing.

UNIT TESTING:

Unit testing mainly focused first in the smallest and low level modules,

proceeding one at a time. Bottom-up testing was performed on each module. As developing

a driver program, that tests modules by developed or used. But for the purpose of testing,

modules themselves were used as stubs, to print verification of the actions performed. After

the lower level modules were tested, the modules that in the next higher level those make

use of the lower modules were tested. Each module was tested against required functionally

and test cases were developed to test the boundary values.


21/29

INTEGRATION TESTING:

Integration testing is a systematic technique for constructing the program structure,

while at the same time conducting tests to uncover errors associated with interfacing. As the

system consists of the number of modules the interfaces to be tested were between theedges of the two modules. The software tested under this was incremental bottom-up

approach. Bottom-up approach integration strategy was implemented with the following

steps. Low level modules were combined into clusters that perform specific software sub

functions. The clusters were then tested.

SYSTEM TESTING:

System testing is a series of different tests whose primary purpose is to fully exercisethe computer-based system. It also tests to find discrepancies between the system and its

original objective, current specifications.

6. CONCLUSION

It has been a great pleasure for me to work on this exciting and challenging project.

This project proved good for me as it provided practical knowledge of not only programming in

ASP.NET and C#.NET Frameworks web based application and no some extent Windows

Application but also about all handling procedure related with Non Visual Search Engine for

Visually Challenged. It also provides knowledge about the latest technology used in

developing web enabled application and client server technology that will be great demand in

future. This will provide better opportunities and guidance in future in developing projects

independently.


28/29

7. FUTURE ENHANCEMENTS

The entire actions performed by the user are stored in the database i.e the right click and

the left click whenever they are clicked.

Preference types are given to the user so that he can search it with more ease.
