INPUT OUTPUT DEVICES

Input output devices are very important component of computer systems. Earlier we have discussed various components of computer system. Here we will discuss about input/output devices, of computer system.

First, we will discuss briefly about input/output devices and then move on to the function and structure of some input and output devices. Finally, we will discuss about the newer technologies in input output devices used in computer system.

Input/output devices are the devices that connect you to your computer. Input devices let you input data and other information into your computer and they also let you give your computer special instructions so that it will know what to do. For example, you can type in data by using a keyboard, or you can input data in picture form by using a scanner or give some instruction by clicking of mouse.

On the other hand, output devices display the results of your computer’s computations. Examples of these would be your computer’s monitor, which displays all of the programs you’re running, as well as the printer, which will print out a hard copy of the information.

COMPUTER VISION

 Computer Vision is the branch of Computer Science whose goal is to model the real world or to recognize objects from digital images. These images can be acquired using video or infrared cameras, radars or specialized sensors such as those used by doctors, scientist, geologist etc. Vision is a most powerful interfacing device for computers. They have the potential to sense body movements and their position, head orientation, direction of the body, and gestures. When the vision based interaction is established with the machine, they could make  the interaction between both of us enjoyable or safer. The algorithms for the computer vision should be reliable, work for different people, and work in odd conditions. The responding time of these algorithms should be very fast. The user should sense delay between when he moves or make gesture and when computer responds. The student will understand the basic techniques of the field of Computer Vision. We will also discuss what are the t...

FUNDAMENTALS OF EMBEDDED SYSTEMS

Embedded systems are basic electronic devices used to control, monitor or assist the operation of equipment, machinery or a plant. The choice of word “embedded” reflects the fact that these are integral part of the system. Uses of embedded system in our real life are increasing day by day. Children need such systems to play video games and to operate chocolate vending machine, Housewives need embedded systems for microwave, TV, music system, and other system appliances. Here we will discuss about basics of embedded system: its uses, its components, its basic requirements in terms of Hardware and Software and support of Programming Languages. We will also highlight some application of embedded system in our real life scenario at the end of this unit. Embedded system is a kind of computer system or computing device that performs a dedicated function and/or is intended for use with a specific embedded software application. It has been found that such systems are not usable as a commercial...

ADVANCED METHODS OF COMMUNICATION WITH A COMPUTER

Human computer interaction is a discipline concerned with the design, evaluation and implementation of interactive computing systems for human use. If the interface is well designed, it will allow the systems functionality to support the user’s task. This unit tracks the development path of human computer interaction from the command line mode to hyperlinks, hypermedia, voice user interface etc. Here we have discussed about different perspectives of communication with computer. Humans communicate with computers in many ways, and the interface between humans and the computers they use is crucial to facilitating this interaction. Different perspectives of human computer interface are human perspective, computer’s persona, user interface and interactions etc. To communicate with computers, we require different kind of input and output devices are available. Controls are the software elements, usually shown on a display, which you use to set preferences and make choices. Some familiar cont...
