Human-Computer Interaction POOJA RANI DEPARTMENT OF COMPUTER SCIENCE & TECHNOLOGY CENTRAL UNIVERSITY OF PUNJAB, BATHINDA poojat320@gmail.com Abstract—Human-Computer Interaction focuses on the interfaces between users and computers. Human-computer interaction is not only the study of how people design, implement and use interactive computer systems but also how computers affect individuals, organizations and society. This covers new interaction techniques for encourage user tasks, provides better approach to information and create more powerful forms of communication. It requires input-output devices and interaction techniques that use them. Human-computer interaction has different accent: computer science (application design and engineering …show more content…
It told us at what extent computers are developed for successful interaction with users. With the definition it is observed that it is the discipline concern with design, evaluation and implementation of interactive computing systems for human use. For achieving this it study major phenomena surrounding them. Human Computer Interaction plays a leading role in the creation of tomorrow exciting new user interface software and technology. With the support of broad spectrum of fundamental research transform human computer interaction experience so that the computer is no longer a distracting focus of attention and become invisible tool that empowers the individual user, facilitates natural, productive human-human collaboration. Goals:- The goals of human computer interaction are to produce the functional systems as well as usable and safe system. In order to produce the computer system with good usability the developer must attempt to:- Firstly the factors that determined how people use technology are needed to be understood. Secondly for building a suitable system the tools and techniques are to be developing. Third is to achieve interaction should be efficient, effective and …show more content…
The basis for this Human computer interaction is the study of cognitive psychology. The results we get from the work of cognitive psychologists told us some lessons. These lessons help us a lot. We can apply these lessons in the design of computer interfaces. Human Information Processing: Human Computer Interaction is also the task of processing the information. The human information processing is depends on the human performance.i.e from displayed information to the response. It will contain various processing stages.i.e how it is arranged, the factors that influence how quickly and accurately a particular stage operates. With the help of appropriate research methods we can discover all these. We can use human information processing analysis in human computer interaction in several ways: When we are designing interfaces and task we considered the facts and theories about the information processing. The empirical studies that are used in HCI to evaluating the cognitive requirements of various tasks require the information processing methods. These methods are used in the Human computer
Cognitive processes are the unseen systems used by our minds to complete tasks such as solving problems, recognising an object, or learning a language. These unseen mental processes take place in the brain, which is a complex piece of equipment often compared to a computer. When the internal workings of a computer are exposed, all that we see are microchips, circuit boards, hard drives and other assorted pieces, which, all work and ...
However, Carr and Turkle both agree that technology has done good, but it has come at the cost of our ability to think critically. In the two articles, both authors heavily emphasize the negative effects of computer technology on how it is diminishing human cognition and the ability to process information.
According to Ahmed et al., 2007, user interface design has received a limited attention from IR researchers. There is a need for adopting human-computer interaction (HCI) techniques into IR interface designs, but this is an issue that has not yet been fully recognised by the commercial database vendors and distributors.
12. Information Processing Approach - Information processing approach is an approach to the study of intelligence that focuses on mental operations, such as attention and memory that underlie intelligent behavior.

Most of the day the human mind is taking in information, analyzing it, storing it accordingly, and recalling past knowledge to solve problems logically. This is similar to the life of any computer. Humans gain information through the senses. Computers gain similar information through a video camera, a microphone, a touch pad or screen, and it is even possible for computers to analyze scent and chemicals. Humans also gain information through books, other people, and even computers, all of which computers can access through software, interfacing, and modems. For the past year speech recognition software products have become mainstream(Lyons,176). All of the ways that humans gain information are mimicked by computers. Humans then proceed to analyze and store the information accordingly. This is a computer's main function in today's society. Humans then take all of this information and solve problems logically. This is where things get complex. There are expert systems that can solve complex problems that humans train their whole lives for. In 1997, IBM's Deep Blue defeated the world champion in a game of chess(Karlgaard, p43). Expert systems design buildings, configure airplanes, and diagnose breathing problems. NASA's Deep Space One probe left with software that lets the probe diagnose problems and fix itself(Lyons).
The way we interact with the world around us has developed significantly since the first desktop computers. First access to the internet for general, public use was really only available to those who were able to afford the large, expensive desktop computer systems, but as computing evolved and smaller, higher performing systems were becoming more available and affordable, our dependence on having this connection to the internet was also developing. The trend continues to grow with the conti...
Using brain imaging techniques like the fMRI, cognitive psychology is now capable of analyzing the connection between the physiology of the brain and its mental processes. Looking into the future, cognitive psychology will without a doubt focus on computer based approaches even more. It is because of this that the field of cognitive psychology will benefit from the advancements in the area of IT. Also, computer based approaches can be joined with classical behavioral approaches, where understanding someone’s mental state from exhibited
The influence of the computer technology is mainly manifested on the internet in daily lives. In the 20th century, mass media went through network improvements around the world. Information technology, digital and networked information communication has brought human free, convenience and interaction. The wide application of information technology improves the working efficiency. It not only helps individuals to get relaxed, but also extend the circle of friends; however, this can be problematic for some individuals as well. Improvement in computer technology may lead to over dependence on the computer, social deficit and changes of communication.
...introduced to all these facts, it is clearly visible that graphical user interfaces played a major role in the development of modern society, and its relations with computing, and IT. Introducing the GUI in the early 1980s did in fact make computers and digital devices more accessible to people, often with no knowledge of computers, and revolutionized the way, in which media and information function today. The GUI has further made the abstract Information Technology more friendly towards a regular user, by allowing user customization of the work environment, and hence, made computers an integrated part of our lifestyle, work and leisure. Finally, because GUI is an inseparable of the most common computer work environments, it has become an element of our compulsory education, which just concretes its role as both facilitator, and prompter of social and life changes.

People in the present society have turned from the use of the old means of communication to the more advanced and technological ways of communicating. Technology has made it easier for people to communicate in a faster, efficient, and cost saving means through the introduction of the communication channels. The world has turned out to be the centre for technology with different technologies emerging daily as the people continue to develop from time to time to cope with the growing technology. The benefits of adopting the communication technology are explained in this article which shows why people do not function without technology.
The late 20th century has successfully witnessed the boom of sophisticated technology, which gave birth to a wide range of technological outcomes, including computer technology. Computer technology, that is a skill to manage information, communicate and a kind of entertainment media, has become an important part in modern life at work, in recreation and social networking. Whether computer technology is better or not is a complicated issue. There are different arguments that need to be examined. Most people support that computer technology is better for individual lifestyles. It improves quality of working and study, provides a wide range of entertainment and is a wonderful tool of communication. On the other hand, others believe that computer
From classroom activities to space flight and everything in between, computers are a vital part of daily life. Everything we do and every aspect of our life is affected by modern technology, like the computers. Computers let us dissect any sort of data. Computers make us reflect, hence we develop. Because of computers and the Internet, we can talk with individuals from diverse nations, and even see them via webcams.
...of input device. As I read and reflect on the vast and varieties of input devices, I now realised its importance of mankind as it brings enormous advantages to us. As a conclusion, input device is a part of computer hardware. It allows users to enter and give instruction to be able in process into the computer system. An input device has improved so much with time. It is substantial to say that people of this generation cannot live without those input device. Input device have not only made our life easier but it also helps in easing our financial and time. For example, the innovation of recent popular application, Wechat. This application is designed for those who are illiterate. People can just touch the ‘hold to talk’ button and says the word out. Then, release the button, the device will record down your voice and sent it out. This will be much easier for them.
