Brainy Fact
In 2019, CBSE introduced AI as a skilled subject for grades 8 and 9. It’s the first board in the world
to introduce it as a discipline at a school level.
Human-Machine Interaction
Human-Machine Interaction (HMI) can be defined as the communication or interaction between humans and
machines through a user interface to fulfil a specific task or operation. With the help of the user interface, a human
communicates with a computer while working on the computer. In human-machine interaction, hardware and
software plays a major role.
Nowadays, natural user interfaces (NUIs) have gained
attention of the humans. NUI is a type of sensory input
system that is invisible to the user. They allow humans
to interact with the machine in natural ways like touch,
speech, and gesture. The main aim of an NUI is to create
seamless interaction between the human and machine.
In this type of HMI, sensors are used to capture human
postures and motions. For example, the Microsoft Kinect
sensor captures your body movement and controls the character in the game.
Now, let us learn about the domains of AI.
Domains of AI
As we have discussed in the previous segment, human intelligence is composed of various domains like perception,
reasoning and learning. Similarly, Artificial Intelligence is also composed of three domains which are Data Statistics,
Computer Vision and Natural Language Processing. They are quite distinct from each other; they together constitute
the concept of artificial intelligence.
When we interact with an AI machine, we actually interact with these domains of AI. HMIs are done through these
three domains of AI:
