ABSTRACT
This paper represents how your PC and Laptop can be controlled from with your T.V remote
with the help of Frontend Application. It means the conventional PC mouse operations controlled by
using T.V Remote. It turns your Remote into a wireless mouse and don’t need any surface. It
requires Forntend application on your computer. This is an implementation of RC5-remote reception
on an 8051 micro controller. The received code is decoded and sent to the PC IR remote software
written in Visual Basic. The cursor position is moved according to the keys pressed. There are two
modes of operation one is as mouse control and second is Windows media player control without
monitor running. The convenience of selecting TV channels using your remote and then pointing the
same remote to your Computer so that you can control the whole system using the single remote
control. The 8051 microcontroller is used to control all the system. An integrated Infrared Receiver
is used to receive the infrared signal from the remote control handset. The received infrared signal
was decoded by using the program, which was written on the ROM of the Microcontroller. The
programs are flashed on the ROM area of the Microcontroller. The Flash memory is a type of
EEPROM. The Details of the switch pressed was sent to the PC through its serial port. In the PC,
Visual Basic was used to control the PC through the API functions.
INTRODUCTION
Consumer electronics devices and personal computers have become inevitable part of our
life. Similarly, mobile devices and computers like CELL PHONEs and Tablets are becoming more
and more commonly used in our daily life. Controlling consumer electronics devices and computers
remotely is an important aspect of the technology. Today, we have remote control devices to control consumer electronic devices such as DTMF sets. Similarly, it is desirable to remotely control
stationary desktop/laptop PCs and their applications. Which offers a wireless means of
communication between the computer and the user and also helps to overcome the disadvantages of
wired and wireless mouse. For ex- ample, an instructor in class-room may want to control a
PowerPoint presentation running on his laptop computer and projected on the screen using a TV
Remote (i.e. wireless mouse). Our application will be primarily based on .Net Technology [4]. The
one side of the system runs on top of the Windows operating system [1] and the other side is a .Net
based application built in IR technology.
Controlling of electrical appliances through IR remote is interesting and very useful
application. This system is widely useful to industries, offices, Banks, hotels, hospitals, and display
boards. In this, IR remote is used for controlling PC\Laptop in your room. We identified the
following as the requirements of a system that enables a TV Remote to be used as a remote control
device for desktop PC while he is moving around in the class-room freely. In this way, he does not
have to go to the laptop each time when he wants to use the Power Point screen. Its architecture is
based on IR Transmitting - Receiving paradigm. It consists of two parts: a transmitter part and a
recevier part. The transmitter part is known as TV Remote. The recevier part consists of
microcontroller, TSOP Receiver, serial communication and PC. This side of the system is capable of
listening incoming connections, sending and receiving data, processing control, commands taking
screenshots, modify applications [5].
This device helps to have better control of computer without mouse. As a result mouse can be
avoided and mouse functions are incorporated in the PC remote control. The commands made by the
user through the PC remote control is read and interpreted by the 8051 microcontroller. The button
pressed in PC remote control by the user will be detected by microcontroller based circuit and these
details are sent to PC via RS232.It can be also used for windows media player functioning. PC
remote control is basically an alternative for a mouse. PC remote control offers a wireless means of
communication between the computer and the user. PC remote control helps to overcome the
disadvantages of wired and wireless mouse [1]. Such devices can be easily attached to computers.
PC remote control has become an indispensable component of modern desktops and laptops.
2. OBJECTIVE
1. It operates PC\Laptop from our living room using with key pad inputs of TV Remote.
2. It allows a power button, as well as a switch or series of buttons to select which device the
remote is controlling at the moment.
3. It allows a numeric keypad for moving the mouse cursor.
4. It allows Arithmetic Keys for controlling media player and slider also.
5. It allowing the user to program command sequences to 5 User defined Programs.
6. It allowing the remote to be programmed to control new devices not already in its code list by
IR coding
7. Accept infrared signals from any remote and transmit them to the device being controlled
using repeater.
3. DEVELOPMENT PROCESS
This paper is about how to control PC applications remotely inside a house, an office, or a
conference room. As the remote control device, we consider using a TV Remote with Visual Basic
capability. For this purpose, we have designed and implemented a frontend application, called
Remote Control that enables a Remote to act as a remote controller device for desktop PCs and their
applications. In this paper, we introduce of, its architecture, and how we have realized it. Remote Control is a system/tool that allows users to control their desktop computer applications from a TV
Remote by using its inbuilt RC5 Protocol technology [3]. The designed system was successfully
tested on a personal computer with the use of TV remote. During the testing stage, the components
and devices were connected and implemented on the workstation and the user by installing the
system interface to Remote. Application successfully enables user to remotely access their
workstation while being cost effective and user friendly. We identified the following as the
requirements of a system that enables PC control using TV remote. Those identified requirements
helped us as the basic guidelines in designing our system.
Ease of use: The system should be easily launched, configured and used. It should have a nice
and graphical user interface [7].
Mobility: The system should support mobility of the user while controlling the desktop computer
application. Mobility can be enabled if the remote control device is portable and if its connection to
the desktop computer.
Wireless: The wireless connection can be a short-range local or personal area connection, most of
the time. In this case, the operating range can be up to 20 to 30 meters depending on the wireless
technology used and on the propagation environment.
Flexible Control: A user should be able to control and execute as much functionality as possible. It
is the best if the user can do everything that he/she can do in a remote manner. The user should be
able to give keyboard inputs and mouse inputs to the desktop PC and also should be able operate
media player while monitor off condition.
Power: The system should be power efficient since Remote are power constrained device and have
limited energy.
Reliability: The system and connectivity should be reliable enough so that a user can control the
desktop computer with-out losing data and/or commands.
Bandwidth: The system should be bandwidth efficient on the wireless link between Remote and
desktop PC.
No Surface: The system can be operated on any direction and those don’t need any surface like
wired and wireless mouse.
