Know all about Human-Computer Interaction(HCI)


The planned design and study of the interaction between human and computer is known as Human-Computer Interaction(HCI). HCI uses security, productivity, and entertainment to accomplish and support human-computer activities. And it is implemented on a variety of computer systems. HCI systems are safe, easy, effective and enjoyable.

It considers a combination of machine and human. It used to support learning on both the human and machine side. Strategies in the programming language, 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 online assignment help for completing your assignments. If yes, then you can completely rely on

Human Computer Interaction
What is Human-Computer Interaction

A Brief History of Human-Computer Interaction

J. Presper Eckert and John Mauchly had come with the idea of human-computer interaction. They built it 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 our assignment experts.

  • 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.  So, 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, Bell Laboratories built up a programmed discourse acknowledgement framework, which effectively recognized the digits verbally expressed by it on the phone from 0 to 9. We could see significant improvements in MIT  in 1959, a system effectively recognized the vowel with 93% efficiency. 

  • 1954 Mobile Phone

Martin Cooper joined Motorola in 1954, 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. He released the first version for the public in 1983.

There was no monitor on the phone and the main part was a 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 the IPTO Information Processing Techniques Office. J.R was the one who proposed the backing priorities that can support the 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 robots were very commonly known at that time, the concept of the Industrial Robot was introduced for the first time in that year. Animate was the company that installed them.

  • 1963, the introduction of Sketchpad

When we talk about CAS, also known as Computer-Aided- Drafting software of the modern time. The Sketchpad was playing the role of CAD in that era. When it comes to computer graphics development, it was one of the major breakthroughs. After that, the mouse and the personal computer were invented which are very user friendly.

1989, The year of Virtual Reality

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

Human Computer Interaction
How does a Human-Computer Interaction work?

How HCI impact life at work? 

We can see several changes at work due to human-computer interaction. It makes a huge impact on people’s life. These changes were in favour or in opposition. Let’s see:

  • Training and learning

Human-Computer Interaction used to play an essential role in 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 in work environments. The present program is set to increase performance and save time on different Human-Computer Interface gadgets. The 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 the 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 at 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 at work. 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 has seen at the start. HCI can be used in electric supply regulation and reduction of temperatures in large machinery.

Effects of human-computer interaction on culture and vice versa

At present, we are crossing through a historical time where individuals are employed to work on a PC. Human work has been limited since 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 the 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 the work area but reaches into a complex world of computer networking.

Where do we see the future of human-computer interaction?

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 instead of utilizing the keyboard, monitor or mouse.

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.

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. 

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.
