Human-Machine Interaction is considered as an AI revolution. Human-Machine Interaction is
the key to successful interactive systems development. It involves the understandings of human
abilities, and technical understanding of hardware and software.
Brief History of Human-Machine Interaction
Since 1960, the information system grew rapidly and with that the need to make the computer
system more friendly & interactive along with making transparent system grow equally.
We all know that computers work on almost all capacities like clerical, programming, designing,
manufacturing, etc. However, until HMI came into the picture, their functionality remained the same.
Human-Machine Interaction is not necessarily between human and computer. It could be
between human and any machine.
With time, business enterprises and other public as well as private organizations deployed systems
that were complex in nature and were more powerful with automation. These machines not only
process information, but also have the capabilities to handle certain situations dynamically like
humans. For example, machines deployed in stock exchange, industrial plants, aircrafts, etc.
The journey of interaction between human and a machine used to be very complex but as
the evolution and inventions introduced, it has become a child's play. Lets look at the devices
which made it easier.
Components of Human-Machine Interaction
To perform a dialog between human and a computer system there are three components that
are interconnected— Human, Machine and the interface between them. A computer interface or
a program establishes interaction between the user and computer. HMI mainly focuses on this
computer interface. Humans and computers use very different channel of communication as you can
understand from the data given below:
S.No. Humans Computers
1. Sensory Memory Keyboard/Mouse/Touchpad
2. Short-term memory Speech Recognition
3. Long-term memory Text input devices
4. Visual Perception Eye-tracking
5. Auditory perception Display screens
6. Speech and voice Printing abilities
