A. Definition of HCI
Human–computer interaction (HCI) studies the design and use of computer technology, focused on the interfaces between people (users) and computers. Researchers in the field of HCI observe the ways in which humans interact with computers and design technologies that let humans interact with computers in novel ways. As a field of research, human–computer interaction is situated at the intersection of computer science, behavioural sciences, design, media studies, and several other fields of study. The term was popularized by Stuart K. Card, Allen Newell, and Thomas P. Moran in their seminal 1983 book, The Psychology of Human–Computer Interaction, although the authors first used the term in 1980 and the first known use was in 1975. The term connotes that, unlike other tools with only limited uses (such as a wooden mallet, useful for hitting things, but not much else), a computer has many uses and this takes place as an open-ended dialog between the user and the computer. The notion of dialog likens human–computer interaction to human-to-human interaction, an analogy which is crucial to theoretical considerations in the field.
B. The differences between the terms “User Interface” and “Human Computer Interface”
The Difference Between The Terms “User Interface (UI)” And “Human Computer Interaction (HCI)” The junction between a user and a computer program. An interface is a set of commands or menus through which a user communicates with a program. A command-driven interface is one in which you enter commands.
C. The important of HCI in every aspect of life
HCI is very important because it will be fundamental to make products more successful, safe, useful and functional. In the long run, it will make more pleasurable for the user. Hence, it is important to have someone with HCI focused skills involved in all phases of any product of system development. HCI is also important to avoid products or project going wrong or totally fail. HCI is extremely important when designing clear intuitive systems which will be usable for people with a varied range of abilities and expertise, and who have not completed any formal training. HCI takes advantage of our everyday knowledge of the world to make software and devices more understandable and usable for everyone. For example, using a graphic of a miniature folder in a computer’s interface helps the user understand the purpose of the folder, as everyone has experience with real paper folders in their everyday lives. Ultimately, if a system is well designed with HCI techniques, the user should not even have to think about the intricacies of how to use the system. Interaction should be clear, intuitive, and natural.
D. HCI Revolution: Past, Present and Future
PAST
since 1941, people already start the invention for computer. As shown in the above video, the earliest computer is Zuse Z3, invented by Komrad Zuse in 1941. This computer is improved version of Z1, and Z2, used to perform statistical analyze of wing flutter. This computer is weighted around 1000kilogram, it has only 22-bits 64 words length for the size of memory. In 1944, team from Harvard University built Mark 1, used by Von Neumann in Manhattan Project. This computer use to calculate immense number to built atomic bomb, which is more efficient than gun design during that era. Mark 1 had 60 sets of 24 switches for manual data entry and can store 72 numbers, with 23 decimal digits long. It could do three additions or subtractions in a second. Another HCI invention in the past is earliest sketchpad and mouse. First sketchpad was built in 1963, by Ivan Sutherland in his PHd project. This sketchpad is considered as pioneer, of working way in between human and computer (other word, HCI). This invention also considered as breakthrough of computer graphics.Earliest operating system built was MS-DOS, in 1981. MS-DOS, stands for Microsoft Disk Operating System, was developed by Microsoft for IBM personal computer in 1980 to the mid-1990’s, before it was succeeded by Graphical User Interface OS particularly Microsoft Windows family.Windows 1.0, first GUI operating system, was released in 1983, to compete with Apple Lisa. Achieve little popularity, Microsoft release an update Windows 2.0 with several improvement: with better user interface and memory management.Microsoft later releases Windows 3.0, and achieved bigger success.
Present
In present, more HCI base invention is done as user centered. From entertainment, to communication, devices, systems in developed and invented for more rich experience by user. Video Game Console .Video game console, one of the HCI-wise creation, is solely invented for entertainment purposes. Start with 1972 Magnavox Odessey, and followed by the famous Atari, now days the world is served with most interactive video game console, Playstation 4. Mobile Phones One of the widely use device, that contain human & computer interaction is mobile phones. First mobile phone in the world was Motorola DynaTAC. Using LED display, this phone have 8 hours standby time, and the display only show numbers to dial and recall only 30 phone numbers.
Future
This is how human interaction with computer in the future looks like. With the interactive and integrated system, it makes human life easier, and not missing anything important. From the workspaces, to living home, future human interaction with computer will be more integrated and full involvement.All this invention will make human life easier and better productivity
