CS408: HUMAN COMPUTER INTERACTION
Human Computer Interaction (HCI)
HCI “Human-Computer Interaction is a discipline for the design, testing and operation of interactive computer systems for human use and for the study of major events around them”
It is now the 21st century and during the last thirty years technology has advanced so that almost everyone communicates with computers in one way or another. See near you how many items have some kind of computer embedded in it? Think for a moment about what you use on a typical day; ATM, mobile, VCR, remote control, ticketing machine, personal digital editors, calculator, clock, camera, toaster, bank, air conditioner, broadcast, satellite, microwave, medical equipment, industries, companies… .the list is endless. Computers are everywhere. We are surrounded by computers. They are now part of our daily routine.
The traditional concept of computers is no more. Unlike the early days of computers, when only highly skilled people used computers, today the scope of knowledge and knowledge of different users is very wide. Computers are no longer just on your desk. Computers are now a tool used on a daily basis. They are everywhere, everywhere, and in everything. They permeate every aspect of our lives. They took our lives. When computers first appeared on the commercial scene in the 1950s, they were very difficult to use, difficult, and sometimes unexpected.
The development of personal computers in the early 1970s was a major milestone because these devices provided interoperable computer power to individual users at a low cost. So, instead of having a handful of experienced programmers exclusively users, people from all walks of life – commercial, farming, education, marketing, defense, production, and entertainment – began using computer systems. Computers are becoming more and more powerful.
Modern Computers
Computers do extra tasks. These technological advances have opened up many new possibilities for computer use. The low cost and the time required to run programs on the first machines meant a variety of commercial systems where computers could be used. Businesses such as banks and accounting, with major record-keeping operations, have become the first to adopt computing technology. Companies involved in operations through ‘rapid’ cycles, such as processing the work of airlines and sales, were unable to use these machines. They were not fast enough or responsive, but this is not a problem with modern computers.
Computers have also found a place in most people’s homes. In fact, this has become so widespread that now almost everyone, young or old, capable or disabled, skilled or unskilled, uses or is directly affected by computers in some way. Machines are rewarding in all aspects of life. So now the concept of life, without a computer is like the idea of a life without electricity, and obviously, it is hard to live without light and a computer!
Human Versus Computer
Humans
Humans are the most fascinating animals on earth. They are the most complex living creatures on earth. It has many variations in its nature. She is wise in her own actions. People think and decide according to their will. Yes, they are naturally free. They love freedom. They think about the problem in a flexible way and can find many solutions that may not have been available before. They can invent. They are not only sensible but also emotional. They also think emotionally. They act emotionally. And fortunately, or unfortunately, they make mistakes. They make mistakes that sometimes become harmful to them and sometimes a blessing to them.
Computers
In contrast, computers are a human creation. They are complex and yet dumb. He can also think but he cannot think of his own will, he thinks how he is directed to think. There is no doubt that its speed is amazing. It doesn’t matter. It has no feelings. It has no emotions, no desires. It works as instructed. And they do not make mistakes.
