Human computer interaction or HCI analyzes humans’ interconnection with computers and examines the developments in the field of machines for productive and fruitful human-computer cooperation. Stated, HCI formulates the design of human and computer interactivities. It concentrates on the design of computer technology and specifically the interaction between humans (the users) and the computers.
Human computer interaction comprises three main parts: the person who’s using the PC, the computer, and the procedure they perform in conjunction with. The users contemplate maximum aspects that may affect their interaction with a machine, including their sight, sound and touch system, age, civilization, academic level, and social inequalities.
Justine Cassell, who’s an American Professor and researcher interested in Human computer Interaction, once had an interview with World Economic Forum to discuss what computers will be able to perform and attain by the year 2030?
From incandescent bulbs that act entirely as electronic computers to 3D printing heart tissue, Justine discussed how Human computer Interaction (HCI) would influence every industry in upcoming years. She emphasized that the developments in Human computer Interaction should benefit and satisfy all levels of society, not just the affluent or those who are contributing to the new economy.
Human computer Interface is a socio-technological system (a term refers to the relationship between society’s multiplex substructure and human demeanor) whose main objective is to bring communication system and powers of the computer to people is such a way that both are approachable and efficient in our acquirements, recreational lives, interface and working.
Feasibility and practicality are the basis and critical points in HCI. As we know, in our quotidian life, several systems and products have been formed with hardly any consideration for serviceability. This inappropriateness brings about infuriation, misconception, and wastage of time.
The improvement in the field of human computer interactions entails designs on both sides of communications. The designer must have a rigorous knowledge and understanding of the accessible software and hardware tools and components on the technology side. On the human hand, the designer must have a better understanding of how humans acquire, understand, and work.
HCI developers strive to acknowledge the aspects and facets that discover how people utilize technology. The main focal point of HCI is on finding the systems and techniques that assist people. Its goals are to produce applicable, feasible, and functional structures. HCI uses productive ways, security, and amusement to support and accomplish human-computer activities.
HCI is applied to several systems of computer which incorporate nuclear processing, air traffic control, computer gaming, and offices. HCI systems are protected, easy to learn, uncomplicated, shielded, practical, and effective to use, and entertaining.
A primitive and cardinal objective of human computer interaction is to provide more facilities to the users of computers by promising that the machines will be more viable, handy, adaptable, and capable of fulfilling the users’ requirements.
Human-computer interrelation has enormous impacts on our society, and it’s, undoubtedly, simplifying the use of computers and other devices for all and sundry. One of the numerous examples of HCI is of a hotel guest as the user to book hotel rooms and airline tickets online. Another example is of the staff of a guest-house as the user to keep a record of the check-ins and check-outs of the guests using a computer system.
HCI has deeply embedded in our daily lives. It helps us to be connected with people having different opinions, different thoughts, and various countries and can get awareness of their culture, lifestyle, and civilization. It’s HCI, which brings emails to the tap of a finger.
Documents and other files can be distributed much more conveniently through emails and text messages. Many manufacturing tasks can be accomplished through HCI. It’s an HCI system which helps you to order online a delicious pizza. This system helps in finding your location through Google Location Service. It tells you to turn left, right, or take the U-turn to reach your site.
The modern and contemporary developments in technology have left significant positive impressions on the human computer interaction. The way humans interact with computers has changed spectacularly over the last decade. Voice commands, eye movement, hand gestures, and touch screen are further advancements in computing.
Human computer interaction examples
Here are a few examples of human computer interaction:
Voice can be a powerful tool for use in human computer interaction. Voice or speech commands allow the computer to turn the speech into text through the process of understanding. Speech recognition technology is on the rise nowadays. This technology provides communication between humans and machines.
Eye movement can be seen as an essential consistent data component for human computer interaction, which is exceptionally critical for people with physical insufficiency. The proposed structure revolves around giving a direct and invaluable shrewd mode by only using the user’s eye.
A hand gesture recognition system amazingly provides the natural, ingenious, and modern way of non-verbal communication with computers. The setup comprises a camera to capture the gesture made by the user and take his hand depiction as an input. It doesn’t require any training, and it takes less computation time.
Touch screens are instinctively uncomplicated to utilize and very different from a keyboard. Instead of a mouse, humans move their fingers around the screen to access icons and other features of their laptops and smartphones. A touchscreen is a concealed and invisible keyboard attached to the front of your computer monitor. Divergent touchscreens work differently. Some can sense one finger at a time and some can detect more than one keypress at once.
Let’s have a look at more examples of the human-computer interface that manifests this relationship has made our lives more cozy, relaxing, and agreeable.
The human-computer interface has made it possible for us to purchase different things via internet, to communicate with our acquaintances, to pay our utility bills, to check our bank balance, to keep our confidential records, to maintain our accounts, to play online games, to save patients’ history, to collect paperless information, to sell our products and contact customers, to manage account systems, to get information regarding goods and services, to conduct different manufacturing systems and ceaseless, uninterrupted running of the industry, to calculate lengthy calculations, to educate students in the form of distance learning programs, to estimate revenues and other business activities and so on.
HCI also helps in setting up video conferences in which all employees of an industry can take part without leaving their offices physically. The examples of human-computer interconnection are never-ending and will thrive on challenges.
The future of HCI holds excellent possibilities. HCI has been regarded as an essential tool for our quotidian lives. We have so dependent on computers that many people become stressed and unable to do anything without computers. In the future, HCI will be a thousand times faster and smarter than the present day.
Technology has made great leaps and bounds in the past few years and we have no exact idea that what kind of drastic change will future of HCI show in our lives? I think the human computer interface will fundamentally change. You won’t carry your interface around any longer. Interfaces will be where you require them to be.
The future computer technology will penetrate the lives of people at an enormous rate. It will vanish into tables, walls, and glass or micro-objects. Sensors will trigger every action for you instead you show it manually. An example is of lights that turn on when you walk into the house or the garage door tracks you when you leave the house.
The future computers will be supernatural. The Future computers will perform inexplicable functions. It will entirely be a world of advanced and astounding technology full of magical things that we can’t visualize yet. We’ll only think of something to occur, and they will. The substantial technological change will come in HCI.
Virtual assistants will become ubiquitous. In-the-air gesture will be the future of gaming and the human-computer interface. For example, imagine a laughing face emoji will be added to your text messages when you laughed out loud and other actions of your body language will be sent through text messages.
It’s patently true, and I believe that future computer technology will make our lives easy-peasy, and trouble-free, and will assist us with better ways in our lives
The future of the human-computer interface is right on the corner. It will surely be a startling and thrilling world.
