Overview and Components of Human and Computer Interaction
Thebestindonesia.com – Along with the development of computer technology which has a positive or negative impact, various views arise among the public on this problem. Between the early period of the emergence of computers and now, the opinions or statements of people are also different.
General View of Computers
We can see this in the following problems:
a. In 1963
Public views/opinions on the early existence of computers:
- The computer can complete various calculations with good results.
- Do not know the applications and programs that support the computer.
- Assume that all types of computers have excellent capabilities and capacities.
- The data obtained is comprehensive and accurate.
- Computers are considered a threat to human potential and self-confidence, not a threat to job opportunities.
b. In 1971
There are different views/opinions among the public towards computers:
- People think computers produce helpful information.
- Assume computers will be able to create new jobs.
- Thinking that computers can degrade human dignity.
c. In 1983
At this time, the emergence of personal computers widely / popularly, which gave rise to new opinions:
- The public believes that personal information is stored in archives, but how it is used is unknown.
- People believe computers will increase their free time to do creative things.
d. In the 1990s
At this time, positive opinions/views of the community towards computers began to emerge. This was because:
- The amount of public interest in computer development.
- The use of computers in various fields with mutually supportive applications.
- Increasingly widespread computer networks to communicate, obtain information, and work.

1.6. History of Computer Development
In this sub-chapter, we will discuss a little about the development of computers. This is very important because it will make it easier for us to study HCI.
The first calculating tool was created by Blase Pascal in the XVII century, to be precise, in 1642.
Characteristic features:
- Digital calculating machine
- its ability is limited to additional operations
A calculating machine that could work automatically without using electricity in 1824 by Charles Babbage.
Characteristic features:
- Calculating machines capable of subtraction operations are called analytical engines
- Arithmetic unit and card input-output facility
- Has memory.
A calculating tool that is automatic but does not yet use electricity by the Harvard Mark I in 1941
Example: Calculator

The first computer that uses Mavrice Wiles invented electricity in 1947.
Characteristic features:
- Using an electronic tube
- Has a giant size
- Birth of Modern Computers in 1948 IBM, the biggest computer product at that time, developed several computers to develop the Automatic Sequence Controlled Calculator machine in 1944. The emergence of these computers made IBM a leading company in the world.
- The birth of the computer with the Stored Program Concept in 1945 by John Von Neuman. Several computer products produced a year include the Universal Automatic Computer (UNIVAC) and BINAC for the Northrop aircraft company in 1949.
- Personal computers appeared 30 years later after electronic computers were made in the 1980s, to be precise. Personal computers, also known as Personal Computers (PCs), were produced by the Apple Computer company and followed by IBM, which seized the world market.
Before we discuss human and computer interactions further and in detail, the following will describe the author’s visualization of IMK itself (W.Verplank and S. Card):
HCI Components
Several components support the implementation of this interaction to form good communication between humans and computers. The components are:
a. Input and Output Devices
Input: Keyboard, Mouse, Remote, Light Pen, etc
Output: Monitor, Printer, sound generator, Patter, etc.
b. Man : Psychologist, Indra, SIM.
c. Interaction Techniques or Dialogue Variety
