With advancement of technology things are becoming simpler and easier for us. Automatic systems are being preferred over manual system. This unit talks about the basic definitions needed to understand the Project better and further defines the technical criteria to be implemented as a part of this project. This project work is on controlling a desktop computer with a remote control. The functions of a computer like opening and closing folders, opening media player and doing its operations, etc can be done from a distance. It requires a few hardware components to build. The project is to be interfaced with the desktop computer through the computer’s keyboard port.

 

 

 

CHAPTER ONE
1.0                                                        INTRODUCTION
A remote desktop service is a system whereby a person is able to connect to and use a specific computer from a remote location as if they were sitting in front of it at the time. The most common example is that of accessing your office computer from the PC or laptop at home, enabling you to manage files, use available resources and generally do everything you’d be able to do if you were actually at the computer in question.
Thousands of businesses the world over use and rely on RDS as a core part of their IT framework. From multinational corporations to educational institutes offering long-distance-learning and so many more besides, there are so many uses to RDS in innumerable industry sectors.
As with so many IT systems and initiatives however, RDS comes with both its inherent advantages and disadvantages. As such, it’s a case of weighing up the good and the bad in order to work out whether or not RDS is the right step forward for you and your business.

1.2                                             OBJECTIVE OF THE PROJECT
The project is designed to use a TV remote as a cordless mouse for the computer. A conventional PC/laptop uses a mouse to operate and control all its applications. As a PC mouse is wired to the system, one has to sit near the PC to operate it.
This becomes very tedious when the PC is used for presentation purposes (when using a projector). The objective of the system is to design a device that can use TV remote as a cordless mouse, and the user need not operate the PC sitting near it – using it to open a open files in the pc.

1.3                                                 SCOPE OF THE PROJECT
A typical TV remote sends coded infrared data that is read by an IR sensor interfaced to an AT8951 family microcontroller. This data so received by the microcontroller sends it to the COM port of a PC through a level shifter IC. This IR code is traditionally RC5 code as followed by some manufacturers. Software named PC remote is used on the PC that recognizes data received from the microcontroller through the COM port and performs the required operation.
Designated numbers on the TV remote are used to perform up – down, right – left cursor movement. Features like left click and right click of the mouse can also be performed with of the TV remote.
Further this project can be enhanced using Bluetooth/ RF technology to overcome the traditional line of sight communication drawbacks of the infrared type.
   
1.4                           PURPOSE OF THE PROJECT
The purpose of the project of controlling a desktop computer with a remote control. The functions of a computer like opening and closing folders, opening media player and doing its operations, etc can be done from a distance. It requires a few hardware components to build. The project is to be interfaced with the desktop computer through the computer’s keyboard port. It has a provision to connect a PS/2 keyboard to make it work simultaneously with the remote control. 

1.5                                         SIGNIFICANCE OF THE PROJECT

• Security – As all of your important data including files and documents will be held in the most secure data centres in the world, there’s practically zero chance of theft or loss. Connection to the remote desktop are protected by state-of-the-art encryption technology, which eliminates the risk of hacking and other data-loss cases common with standard computing and networking.

• Flexibility – The core purpose of RDS is to allow workers to perform their duties from literally anywhere at any time. The only thing needed is a computer and a secure internet connection, which adds up to the kind of freedom and flexibility that would be otherwise entirely impossible.

• Lower Costs – Often when using a remote desktop system, it isn’t necessary to invest in multiple copies of the same business software packages as they can be used via a single machine. In addition, the computers used to access the host computer do not necessarily have to be high-performance machines with equally high prices.
• portable
• can control devices more comfortably

      1.6                                     LIMITATION OF THE PROJECT

• Downtime – If the service provider is anything other than flawless in its consistency and performance, there’s a strong risk of downtime. And when it comes to downtime in the world of RDS, it can leave the entire network/system inaccessible until the necessary repairs have been made.

• Network Dependency – A little like the above, the system will work fine just as long as all third-party computers have strong and reliable internet connections available to them. If not, the system is completely out of reach.

• Bottlenecks – Depending on the power of the host system and how many are trying to access it at the same time, it’s possible that bottlenecks can be caused and reduce performance.

• Knowledge – The administrator of the RDS must have solid knowledge of the subject and be readily contactable if and when any problems should occur during normal working hours. Without the necessary help on standby to turn to in the event of a system outage, the results could be dire.
• Works using a battery which has to be regularly replaced.
• Has distance limit in controlling devices.
