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.
Brainy Fact
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 organisations 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:
