Introduction

In the post-PC era, the market for network-

connected devices continues to grow at an

enormous rate. While new classes of devices like

smart cellular telephones, pagers, and PDAsproliferate, traditional consumer electronics

including televisions, VCRs, CD players, and game

machines are also becoming smarter and gaining

new capabilities. Whether these devices are new

or just more powerful versions of existing

products, all are becoming increasingly

interconnected across a network.

Today there is a strong need for solutions

which can make finest use of consumer electronic

devices like cellular phones and pack the power of

computer in it. May it be a large enterprise or a

huge network, user today wants the power to

manage then through his cellular phone or PDA.

Every human has a cell phone so why not

use it for variety of other purposes apart from

making calls.

We propose to use the cell phone as

remote control for a PC or laptop using Bluetooth

where the user can easily do common tasks from

his cell phone such as control slides of slideshow

or control the volume of media player restart or

shutdown the computer etc.

The solution for the above problem will

be incorporating a Mobile application wherein

through your cellular phone you will be able to

communicate with the computer executes the

applications in it.

The above said solution can be achieved

by using J2ME on the cellular phone, which will

send instructions to the software running on the

ANALYSIS OF THESYSTEM

Existing system



15/43

Blue Mouse

Existing system here would mean a

computer system with mouse and keyboard attached to

it. We can operate or control a computer system with

the help of a mouse and a keyboard. If we want to

operate computer system then we have to stay near

computer only. Many times it happens that we want to

change a slide in a power point presentation or an

audio record in a media player then we have to move

near computer system every time.

Disadvantages:

1. The system can not be operated from long distance.

2. Person/operator has to stay near computer system.

Proposed system

Today there is a strong need for solutions

for which can make finest use of consumer electronic

device like cell phones and pack the power of computer

in it.

Now a day everyone has cell phones. So why

not we use it for verity of other purposes apart from

making calls.

We propose to use the cell phone as remote control for

a pc using Bluetooth, where the user can easily do

common tasks like changing slides opening new folders

shut down computers and etc.

The solution for the disadvantages of existing

system is incorporating a mobile application wherein

through cell phone one will be able to control and

execute applications in it.The solution can be achieved by using J2ME on

the cell phone, which will send instruction to the

software running on the pc via Bluetooth and that

software will complete the request.

Advantages:

1. We can operate computer from long distances (within

the Bluetooth range).

2. An interface on the cell phone helps for giving proper

commands.

Software Engineering ParadigmApplied

Software Engineering Paradigm can be

considered as a set of methods, tools and procedures

that it is used to develop software. A method out lines

ways of planning a software project, analyzing userrequirements, designing a system, coding it, testing it,

etc. It also outlines certain diagrams and notations that

we can use to depict our system-in other words it

provides the technical how to answers, to actually

build the software. A tool provides automated or semi

automated support to implement a method. Procedure

tells us the sequence in which the software developer

tasks have to be performed, how quality has to be

enforced.

The various engineering paradigms are as follows:

Water Fall Model

Evolutionary Model

Formal System Development



26/43

Blue Mouse

Spiral Model

Incremental Model

Water Fall Model

Water Fall Model is useful when a system to

be developed is highly structured means when there is

a clear procedure to solve the problem this model can

be used.

This takes the fundamental process activities of

specification, validation and evolution and represents

them as separate process phases such as requirements

specification, software design, implementation, testing

and so on.

The principle stages in Water Fall Model are,

Requirements analysis and definition: The

systems services, constraints and goals are establishedby consultation with system users. They are then

defined in the detail and serve as a system

specification.



27/43

System and Software design: The system design

process partitioned the requirements to either

hardware or software system. It establishes overall

system architecture. Software design involves

identifying and describing the fundamental software

system abstraction and their relationship.

Implementation and unit testing: During this stage,

the software design is realized as a set of programs or

program unit. Unit testing involves verifying that each

unit meets its specification.

Integration and System Testing: The individual

program units and program are integrated and tested

as a complete system to ensure that the softwarerequirements have been met. After testing, the

software system is delivered to the customer.



28/43

Blue Mouse

Operation and Maintenance: Normally this is the

longest life-cycle phase. The system is installed and put

into particular use. Maintenance involves correcting

errors which were not discovered in earlier stages of life

cycle, improving the implementation of system unit and

enhancing the systems service as a new requirement

are discovered.

SOFTWARETESTING

SOFTWARE TESTING

Testing:

Testing is the process of testing the code or

the system to remove the bugs if parents. The bugs



33/43

Blue Mouse

may be the program errors, exceptions in case of white

box testing, low response time in case of load testing.

Testing is not ysed to check the program logic, it only

checks the bugs if present.

Testing can be categorized into many types

depending upon the needs of the system.

Unit, black box, integration, functional,

system, end-to-end, smoke regression, load, stress,

performance, usability, adhoc, exploratory, user

acceptance, alpha, beta, comparison, mutation.

Out of these many kinds of testing strategies

we tested our system using the following test

strategies:

Unit Testing - This is done to test the code.

White Box Testing - This is done to test the code.

Black Box Testing - This is done to check the

functionality.

Integration Testing - This is done to check theclient-server

connectivity.



34/43

Blue Mouse

Validation:

The comparison between the actual characteristics

of something(e.g. a product of a software project and the

expected characteristics). Validation is checking that you

have built the right system. This is done after completing the

coding.

Data validation means range of value that main

world attribute can take if user enters more or less this

value; he will be warned and asked for re-entry. The data

validation is been done for many attributes.

Verification:

The user should Log-in to valid User name and

Password.

The user must specify the respective server name while

Logging.

Group name should not contain spaces.



35/43

Blue Mouse

New user should be authenticated before joining any

group.

Unit Testing:

During the implementation of the system,

each module was tested separately to uncover error

within its boundaries. Detailed design description were

used as a guide in this project. Each unit is tested

separately using dummy data.

White Box Testing:

White box testing is based on

knowledge of the

internal logic of an applications code. Test are based

on coverage of code statements, branches, paths,

conditions.

Independent Path Test:



36/43

Blue Mouse

All independent paths through the

module were executed to assure that they behave

desirably.

Black Box Testing:

Black box testing is not based on any

knowledge of internal design or code. Tests are

based on requirements and functionality.

Interface Test:

This test was carried out to assure

that the information properly flows out of the

program units.

Integration Testing:

Testing of combined parts of an

application to determine if they function together

correctly. The parts can be code modules, individual

applications, client and relevant to client/server and

distributed systems.



37/43

Blue Mouse

All the units were integrated and

test was carried out to ensure that no flow existed in

the system. Test was successful of the proposed

system.
