Abstract

“HCI concept came into the spotlight after various researches; the improvement of GUIs paved the path for a better and advanced interaction between humans and computers.

Interaction with computers has become so close; it almost devoured the human life styles. Future human life will be much dependent upon technology than ever before.”

Introduction

People live in a curious and modern world where they go to no lengths to embrace technology. It is people who pick and choose what to use more efficiently. HCI (Human Computer Interface) is one of the catalysts which revolutionised the computer technology to a greater extent during the past three decades.

HCI concept came into the spotlight after various researches which had been done on various universities and other research labs mainly across USA. But HCI took the centre stage after the rapid growth of GUI (Graphical User Interface) s. HCI revolutionised the computing technology and even laid the foundation for WWW (World Wide Web).

Evolution of HCI

The improvement of GUIs paved the path for a better and advanced interaction between humans and computers. According to http://old.sigchi.org/cdg/cdg2.html#2_2_1 website, “Human-computer interaction arose as a field from intertwined roots in computer graphics, operating systems, human factors, ergonomics, industrial engineering, cognitive psychology, and the systems part of computer science.”

Thus introduction of personal computers have made the growth of HCIs more rapid. Following will briefly determine the gradual development of HCI via GUIs and other various interactions.

• Ivan Sutherland was the first to show direct manipulation of graphical objects via sketchpad, a system build at Lincoln labs. Apart from that William Newman's Reaction Handler, AMBIT/G system was among the pioneers of developing GUI which eventually aided in the evolution of HCI technology. Introduction of Xerox Star, Apple Lisa and Macintosh computers laid foundation for a speedy growth in HCI throughout the world. Distance between human and computer became much closer due to the emergence various GUIs and tactile technologies which had enabled a smoother interaction among the humans and computers. Also the inclusion of mouse as a tactile device which can interact with a computer GUI proved to be a revolutionized aspect in the evolution of HCI.

• Whenever since computer and its technology became household equipment, the interaction between human and computers had become a reality which not only belonged to IT professionals, but also for ordinary people. With the development of windows, a virtual place in the computer which people can interact, and applications included in the windows environment aided in improving far better interaction among people towards the computer. Gradually with the inclusion of applications such as drawing programs, word processing programs, spread sheets, etc. HCI became a normal routine in peoples’ life.

Important features and facts to ponder

Typically HCI mainly concerned about the design which interacts with the user. Over the past couple of decades, the usability has increased immensely, providing far better interaction between human and computers.

1 Operating systems and their role in HCI

Since the evolution of GUIs, the operating systems which GUIs built upon played a major role in dissolving the fact that GUI is only a virtual mirage. From typing commands to interacting with graphical objects on the screen, operating systems have been an essential instrument in HCI.

“From GUIs to multi-touch, speech to gesturing, the ways we interact with computers are diversifying as never before.”

Harper, Rodden, Rogers, Sellen (2008) Being Human: Human-Computer Interaction in the year 2020, 1st Edition, United Kingdom: Microsoft Research Ltd

Operating Systems which aided HCI, in brief

• Microsoft’s windows operating system platform was a pioneer in closing the gap between humans and computers via its graphically armoured operating systems. It has devoured the computers with its user friendly environment. Sooner GUI objects on the windows operating systems, which people interacted with clicking the mouse, became household names.

• With the growth of mobile computing, android, apple operating systems revolutionized the HCI via tangible interfaces. It closed the gap between human and computers, allowing a smoother interaction by the touch of a finger.

Thus operating systems played a vital role throughout the evolution, and will play a major role towards the future of HCI.

2 HCI in the making of a virtual reality

One of the salient features of HCI is the creation of a virtual world, which make day-to-day routines of humans much easier with a touch of a fingertip. From buying goods to paying bills, all are being done through virtual interfaces. Growth of HCI have overtaken most of the essential aspects of human life to its virtual reality, and made the living more comfortable.

Towards a Virtual Reality in Brief

“By 2020 more people than ever will be using computing devices of one form or other, be they a retiree in Japan, a schoolchild in Italy or a farmer in Africa.”

Harper, Rodden, Rogers, Sellen (2008) Being Human: Human-Computer Interaction in the year 2020, 1st Edition, United Kingdom: Microsoft Research Ltd

As scientists predicting, the whole world is going through a technological revolution, thus HCI will be a fact to ponder. Since the gap of human and computer interaction is getting closer day by day, people will glue to the virtual reality which is being created by HCI.

• Transformation in interaction between human and computer will make virtual reality a fact hard to resist. Computers will work upon the control of human eye; embedded computers in human bodies will calculate every aspect in human body interacting accordingly, which will results in closing the boundary between computers and humans towards a virtual reality.

• With the embedded computation, people will no longer have to depend upon interface stability, which will make a virtual reality wherever people step into. Combining of physical objects via digital information will make a virtual mirage in the lives of people, which is hard to resist.

Glimpse towards the future of HCI

1 HCI for enhancing human life

From point-and-click to tangible interfaces, HCI has come a long way during the past couple of decades. Human life style has altered accordingly to the changing technology, which has improved the quality of living up to certain extent. Interaction with computers has become so close; it almost devoured the human life styles, making them an essential aspect of living.

Future human life will be much dependent upon technology than ever before which will make the living comfortable. Since everything future human needs can be fulfilled with a simple interaction through a computer, it is obvious that the life style will improve.

“The interfaces of the future will use gesture recognition, speech recognition and generation, "intelligent agents," adaptive interfaces, video, and many other technologies now being investigated by research groups at universities and corporate labs”

Myers (1998) A Brief History of Human Computer Interaction Technology, 1st Edition, ACM interactions

• Embedding of bio-sensing devices will enhance the human health and hygiene, further preventing human from diseases.

• Computers will be embedded into furniture to clothes, making human life a digital dependant.

• Sophisticated computers and artificial intelligent devices will enhance human life by reducing workload of human beings and will even involve in complex procedures.

• Online learning will enable in compiling the knowledge of the whole world into every door step.

• Future of HCI will be so powerful; it will almost take over every aspect of human life. Interactions will be upon touch, eyes, gestures, etc. which will eventually turn human beings into semi-robots. Typical human will interact with thousands of computers per day, making a total virtual life. Robots and other intelligent devices will reign supremacy in the future upon many aspects.

• Creative engagement, social integration will reach its peak with the tight interaction between computers and humans. Since everyone is interconnected via embedded devices and other modes of HCIs, communication among others will be a matter of seconds.

2 Uses and Impacts of HCI

Uses

HCI will be used upon every possible aspect of the human life, and it will be varied from bio-sensing clothes to highly sophisticated computers.

“In future, a computer is more likely to be embedded in furniture, rooms, cars, doors, clothing, and packaging than in a recognisable ‘box’.”

Harper, Rodden, Rogers, Sellen (2008) Being Human: Human-Computer Interaction in the year 2020, 1st Edition, United Kingdom: Microsoft Research Ltd

• HCI will also be used upon people with physical disabilities to interact with computers according to their wish.

• Human brain waves will be used to interact with computers which will enable control over human emotions.

• With the use of high-bandwidth interactions, people will never feel left behind as interconnection among anyone will be a matter of seconds via embedded HCIs.

• Use of sixth sense devices where communication is done with hands, will grant people to access internet, check mail and do other related things everywhere on the earth.

Impact of HCI

Since whole world is going through a technological revolutionising period, the HCI will reach its peak. Thus there will be many impacts upon society.

Benefits

• Considering about the society and human life, growth of HCI will enable a stress free life as computers will be doing more work and humans will be just giving orders.

• Whole world will be a one village as HCI will be interconnecting everyone on the plant. It will aid in spreading knowledge throughout the whole world.

• Human life expectancy rate will go up due to the growth of bio-sensing devices, which will involve in tracking human health and providing pre-warnings when they sense abnormality within the human body.

Drawbacks

• Since future human will be fully interacted worldwide via embedded and other various kinds of computer technologies, the privacy of humans will be a threat to be ponder.

• People will face new kinds of health issues such as loss of vision, due to excessive hours of interaction with computers.

• Another drawback will be the humans’ sole dependency upon computers for every essential aspect of life. Since computers will be providing all the essential guidance and support, the creativity and the thinking capacity of mankind will fade away. Moreover, people will find it hard to survive without the interaction between computers in their daily routines, which will eventually develop human kind into semi-robots.

Conclusion

Considering all the facts, it is definite that HCI will revolutionise the whole world and the benefits which people can gain will be plenty. But not being too complacent, considering the drawbacks of the technology and mapping the technology accordingly will be the most appropriate thing to do.

...The History of Computers Thousands of years ago calculations were done using people’s fingers and pebbles that were found just lying around. Technology has transformed so much that today the most complicated computations are done within seconds. Human dependency on computers is increasing everyday. Just think how hard it would be to live a week without a computer. We owe the advancements of computers and other such electronic devices to the intelligence of men of the past. The history of the computer dates back all the way to the prehistoric times. The first step towards the development of the computer, the abacus, was developed in Babylonia in 500 B.C. and functioned as a simple counting tool. It was not until thousands of years later that the first calculator was produced. In 1623, the first mechanical calculator was invented by Wilhelm Schikard, the “Calculating Clock,” as it was often referred to as, “performed it’s operations by wheels, which worked similar to a car’s odometer” (Evolution, 1). Still, there had not yet been anything invented that could even be characterized as a computer. Finally, in 1625 the slide rule was created becoming “the first analog computer of the modern ages” (Evolution, 1). One of the biggest breakthroughs came from by Blaise Pascal in 1642, who invented a mechanical calculator whose main function was adding and subtracting numbers. Years later, Gottfried Leibnez improved Pascal’s model by allowing it to also perform such operations......

Okey The University of Georgia [pic] Research in the area of user interface design for computer-based learning environments (Jones, 1993) found that screen and interface design should be considered at the same time during the design and development process. Additionally, the research produced a list of interface design concepts and a corresponding list of guidelines for implementing those concepts. The concepts presented in this paper are broad issues to be considered during the design and development process. The guidelines that are associaàted with the concepts are intended to be flexible, and allow for the creativity of the individual designer, and the needs of a particular project. Names for some of the concepts were taken from an analysis of the literature in computer-based instruction (CBI), computer-based learning environments, and human computer interaction (HCI). Names for the other concepts were emic categories generated by the participants in the study. The guidelines were derived through an analysis of the literature, an analysis of six commercially produced computer-based learning environments, and interviews with the designers and developers of the six computer-based learning environments. Further research is being conducted to determine how designers and developers can implement these guidelines. If......

Evolution of the Human Eye

...The human eye is an incredibly complex organ, it acts like a camera to collect and focus light and changes this light into an electrical signals that the brain then reads to form images. Instead of using film, the eye has specialized components such as the retina that detects light and process it using many types of neurons. The eye is so complex that its origin has long been a hot topic of debate and is often used to defend a creationist point of view, they say the eye is too complex to have evolved instead it must has been designed. The eye is a system that cannot function in the absence of any of its components. Even Charles Darwin remarked in the origin of species that ‘it might seem absurd to think the eye formed by natural selection’. (Fernald. R.) He did however firmly believe that the eye did evolve in this way, despite the only the small amount of evidence at that time. This evidence is hard to come by since soft-tissue structures like the eye rarely ever fossilize. However the scientific community has made recent advancements in tracking the origin of the eye by studying the formation of eyes in developing embryos and comparing these different structures and genes across many species to construct when and where key traits arose. The study indicates that ‘the human eye took shape in less than 100 million years, evolving from a simple light senor to sophisticated optical organ.’ (Lamb. T) Humans have an unbroken linage going back for 4 billion years. Almost a......

Zaki, and James Thompson Abstract Over the past two decades, Computer Science (CS) has continued to grow as a research field. There are several studies that examine trends and emerging topics in CS research or the impact of papers on the field. In contrast, in this article, we take a closer look at the entire CS research in the past two decades by analyzing the data on publications in the ACM Digital Library and IEEE Xplore, and the grants awarded by the National Science Foundation (NSF). We identify trends, bursty topics, and interesting inter-relationships between NSF awards and CS publications, finding, for example, that if an uncommonly high frequency of a specific topic is observed in publications, the funding for this topic is usually increased. We also analyze CS researchers and communities, finding that only a small fraction of authors attribute their work to the same research area for a long period of time, reflecting for instance the emphasis on novelty (use of new keywords) and typical academic research teams (with core faculty and more rapid turnover of students and postdocs). Finally, our work highlights the dynamic research landscape in CS, with its focus......

Introduction to Human Computer Interaction

...Introduction of Human Computer Interaction Human computer interaction is communication between user and system, and is the study of the way in which computer technology influences human work and activities. With the rapid advancement of technology, our lives almost depend on computer or any kind of machine. For example computer, Global Positioning System (GPS), cell phone, and even for tuning musical instrument you have a digital device that helps tune your instrument. Therefore it is very important that the interface of any device should be very user friendly, meaning the person who does not have much knowledge of system should be able to use it. Because not all of our populations are computer or technology literate, but still they have to use it because of requirement and necessity (Dix, A. 2009, pp. 1327-1331). Analysis of Google Home Page The strength of Google is the simple look and feel which every single user can access and gain useful information. The speed of the search engine is amazing and can gain any information within no time. Google has the provision to integrate with various languages and its localized search is an added features compared to other search engines. The information is well organized. Google’s products are its major strength which has created a huge user base. This enhances the trust to its customers and shareholders.

Evolution of Computer

...Background of the study The computer as we know it today had its beginning with a 19th century English mathematics professor name Charles Babbage. He designed the Analytical Engine and it was this design that the basic framework of the computers of today are based on. Generally speaking, computers can be classified into three generations. Each generation lasted for a certain period of time,and each gave us either a new and improved computer or an improvement to the existing computer. First generation: 1937 – 1946 - In 1937 the first electronic digital computer was built by Dr. John V. Atanasoff and Clifford Berry. It was called the Atanasoff-Berry Computer (ABC). In 1943 an electronic computer name the Colossus was built for the military. Other developments continued until in 1946 the first general– purpose digital computer, the Electronic Numerical Integrator and Computer (ENIAC) was built. It is said that this computer weighed 30 tons, and had 18,000 vacuum tubes which was used for processing. When this computer was turned on for the first time lights dim in sections of Philadelphia. Computers of this generation could only perform single task, and they had no operating system. Second generation: 1947 – 1962 - This generation of computers used transistors instead of vacuum tubes which were more reliable. In 1951 the first computer for commercial use was introduced to the public; the Universal Automatic Computer (UNIVAC 1). In 1953 the International Business Machine......

The Human Computer Interface

...The Human Computer Interface By: Dustin Hudson March 4, 2014 CIS 106: Prof. Howell In today’s world, there are various types of technology that humans interact with on a day to day basis. Technology is an ever evolving industry that is constantly trying to meet the demands of its consumers. Whether you are trying to write a document in Microsoft Word, talking to your IPhone using Siri, or having your respiration rates being monitored by a machine at the doctor’s office, all of these technologies are designed to interact with humans. The science behind designing technologies to meet the needs of human interaction is known as the human-computer interface. The human-computer interface involves many different perspectives in order to be effective. Most companies assemble a team when trying to develop a software program. This team can include people from departments such as “marketing, engineering, and manufacturing to get different perspective” (G. Anderson, D. Ferro, and R. Hilton 2013). Some teams even include psychology majors in order to get perspectives on human behavior and human memory. Developing a sound software program is very important in order for it to be successful. It has to be not only technically sound and reliable, but it also must be visually appealing to the consumer and work hand in hand with that person’s memory storage. A person has three types of memory, sensory storage, short term memory and long term memory. “Sensory storage works as a buffer......

Evolution of Computer Applications & Architecture

...Evolution of Computer Applications and Architecture By Ken Jacobi, Computer Architecture (IT-501) In discussing the evolution of computer architecture, we find that there are many angles on how people tend to view things. Some will take consideration in how things have changed over the last few years. Others will take a stronger look at the direction of where they believe technology is going. A third focus is in regards to the unexpected mistakes that people have made. In conjunction with the past, how can these mistakes be avoided in the coming future and evolution of technology; both for equal and competitive reasons. In part with this, we can turn to the very basic view about what makes a good design. Many architectural topics once began with the idea that if you build something and develop it correctly, change is not something one should expect. If it’s developed right the first time then you don’t have to change it. In this successful strive, people have come to the underlying conclusion that this is a very unrealistic position to be. A very good place to stress the relevance here is by dating back to the start of an exciting architectural turn of events that have gotten us to where we now are: the birth of modern computing. Many will say that this “landmark” of progress has lead to an evolutional launch that we constantly live within. It’s safe to say that these embarking events once began somewhere amongst the early 1970s. Coming out of the...

Computers have become such a necessity in my everyday life that it is hard to think what I would be doing without them. In today’s economy a cheap price on a personal computer is not hard to find. Personal computers have extraordinary amounts of uses compared to those in the past. Some older computers only had the ability to calculate data that was entered into them. As personal computers have advanced, so have the operations that they can perform. Specifically, I use my computer for many helpful things. I have used my computer to plan multiple vacations and book airfare online. Also, I have used it to do homework for classes in the past. Unfortunately, I look at personal computers as outdated. Laptop computers are a new “must have” item. Today owning only a personal computer is considered a thing of the past. Before college, the only computer I owned was a personal computer. Now that I’m in college, my professors post things online, use email, and require typed papers. Since I have to use a computer to complete my work I had two options, try to find a computer on campus or drive home to use my PC. In......
