Human-Computer Interaction


Introduction: The planned design and study of the interaction between human and computer is known as Human-Computer Interaction. HCI uses security, productivity, and entertainment to accomplish and support human-computer activities and is implemented on a variety of computer systems, including atomic processing, air traffic control, office, and computer gaming. HCI systems are safe, easy, effective and enjoyable.

HCI considers a combination of machine and human. It used to support learning on both human and machine side. Strategies in the programming language, development environment, operating system, and computer graphics on the machine are relevant. On the other hand, disciplines of graphics and industrial design, communication theory, linguistics, social science, human factors, and cognitive psychology are significant in the human side. Human-Computer Interaction is a topic that you might search for an online assignment help for completing your assignments.

What is Human-Computer Interaction


J. Presper Eckert and John Mauchly, in the year of 1943-45 at the University of Pennsylvania’s Moore School, built for the War effort by Prescott, however not given to the military until the end of the war, the ENIAC which is also known as Electronic Numerical Integrator and Computer was the main universally useful electronic digital computer. The width of the computer was 150 feet with 20 blazing light and it was around 300 X faster than the Mark 1.

Knowing history is very essential while making the assessment on Human-Computer Interaction as suggested by various assignment help websites.

1945 Vannevar Bush

An electromechanical machine known as Memex is used for saving a lot of articles in a machine and organizing them in a manner that,  an individual can get numerous articles or pictures and remark on the monitor and also they have the ability to give whatever comments they want and it can be stored and backup.

1952 Speech Recognizer

In 1952, as the examination subsidized by the U.S. government started to quicken, Bell Laboratories built up a programmed discourse acknowledgment framework, which effectively recognized the digits verbally expressed by it on the phone from 0 to 9. Significant improvements of MIT were followed In 1959, a system effectively recognized the vowel with 93% efficiency. After that seven years after the fact, a system with 50 vocabularies was effectively tested.

1954 Mobile Phone

Martin Cooper accomplished an Electrical Engineering degree at the Illinois Institute of Technology. Later, in the year 1954, he joined Motorola, he drove the team of the researcher to build up a portable telephone, the Motorola Dyna Tac, which was known for its Dynamic Adaptive Total Coverage. Its weight was about a kilo, 1089 grams, in the year 1983, they released the first version for the public.

9 x 5 x 1.75 inch was the size of the mobile phone, with a total of 30 onboard circuits. In comparison to the mobile phone today, there was no monitor on the phone and the main part was call, listen and dial (what more you want?). The batteries were very heavy and were able to last only for approx 35 min of talk time and that only after a recharge of 10hrs.

1960, J.R Licklider

J.R Licklider was one of the known people in the history of Computer Science. He was the manager in IPTO Information Processing Techniques Office, and it was a part of Advanced Research Projects of Pentagon, he was the one who proposed for the backing priorities that can support internet between the year 1963-1964. He also developed the concept of “hypertext”, “mouse” and “windows”.

Middle of the 1960s

During this time, the PCs used to be very heavy and big, also they were very expensive and this was the reason that only some people were able to operate PC. At that time availability of PC to the common people and making them more efficient was one of the major tasks.

1961, Era of Industrial Robots

Although the robots were very commonly known at that time, the concept of Industrial Robot was introduced for the first time in that year and the company in which it was installed was UNIMATE.

1963, the introduction of Sketchpad

When we talk about CAS, also known as Computer- Aided- Drafting software of the modern time, then Sketchpad was CAD of that era. When it comes to computer graphics development, it was one of the major breakthroughs.

The concept of GUI (Graphic User Interface) was developed from Sketchpad only, and also the concept of modern OOPs (Object Oriented Programming). It was Ivan, who displayed that computer graphics can be utilized for both technical purposes as well as artistic purpose.

1963-1964, Mouse

During this period, the mouse was invented by Douglas .E.Engelbart in Stanford Research Institute laboratory and in the year 1970, its patient was issued.

Personal Computers

A personal computer is a device whose features like capabilities, size and price make it very user-friendly.

1989, Virtual Reality

A Virtual Reality is the computer simulated graphics that resembles the reality of a place and the person watching may feel the view physically.

How a Human-Computer Interaction works?

Role of HCI at work

Training and Learning

Human-Computer Interaction used to play an essential role in the training and learning, with the use of guided techniques and projectors. The projector has a major role during training. It can meet the needs of the user which can be both an expert or a regular user.

Enhance the use of Software

Today, clients can utilize the program with hardware to improve their efficiency at work environments. The present program is set to increase performance and save time on different Human-Computer Interface gadgets. Automatic Checkout Machine used at the hypermart is one of the examples in this case.

Specific interfaces for disabled people

There are various Human-Computer Interface gadgets that are utilized for individuals with a disability. These devices are intended for daily support for disabled in regular day to day life. Automatic typing by the software without any interference.

Interface for the environment of Hostile

To decrease the risk of risks and hazards, exceptional interfaces have been set up for use in antagonistic situations. The model could be Military Night Vision Glass, which can be utilized by Armed Forces to look better in the night. Automobile parking sensors are introduced on vehicles to reduce mishaps.

Safety and Health

Human-Computer Interface used to play a critical role in increasing safety and health in work. In situations where the machinery is used manually, at that point, there can be safety and health issues. HCI devices have been installed today so that the security and health of the scholars be made a priority. In case of electric shock, earth cable and cutoff system is seen at the start. For large machinery, HCI can be utilized in electric supply regulation and reduction of temperatures.

Working Environment that is Varied

Some HCI gadgets can be utilized for different working environment conditions. For example, ATM cards we use for monetary exchanges can be utilized in various conditions.

Effect of human-computer interaction on culture and vice versa

In the present time, we are crossing through a historical time where individuals are employed to work on a PC, human work has been limited since the PCs are capable of doing almost everything. The system of the network is getting to be universal in everyday life and all are more effectively taking part in the science and business foundation.

Data innovation has grown drastically in the previous two decades and can now effectively support a worldwide market. Specifically, the Internet or World Wide Web has empowered worldwide distribution of products and services through sites. To push ahead in the coming years, for HCI, it is important to have superior knowledge of developing and dynamic communications in which Focus is never again restricted to work area but reaches into a complex world of networking.


We can clearly observe the tremendous future of HCI. The current physical interaction will go on intelligent 3D projection, where 3D projections are evaluated from a portable gadget as instead of utilizing the keyboard, monitor or mouse. Speeches and body gesture will be utilized for the discussion.

This will take the HCI to another dimension, where the client won’t just think and type, but will also physically perform and chat on the PC. At the point when this level is accomplished, then, the way of living will be totally impacted and replaced.


Every one of these improvements is because of new programming and innovations that are being utilized. Ongoing research plans, for example, ethnography for HCI advancement are additionally helpful. The web application is being created with the utilization of new methodologies. Along these lines, the environment of HCI has grown a lot.

HCI has turned into a basic part of everyday life for Americans and a large number of other people around the world. Concentrating on the best way to interact with them with inspecting these sites has proved that it is critical that website designers should concentrate on HCI while structuring sites.

Even though that focus may not be to improve the collaboration for the normal user, rather the focus must be to improve the connection for everybody who can utilize that site. Taking a look at the sites evaluated here, which are all around intended for every normal user, designers still have far to make these locales simple to utilize.
