Artificial Intelligence (AI)
What is artificial intelligence?
Artificial intelligence (AI) is a machine that can simulate intelligent behaviours similar to that of a human
AI is a system that can:
Learn - acquire new information
Decide - analyse and make choices
Act autonomously - take actions without human input
There are two main types of AI:
Weak AI, also known as narrow AI, is designed to perform a specific task or set of tasks
Strong AI, also known as artificial general intelligence (AGI), is designed to perform any intellectual task that a human can do
Advantages and disadvantages of AI
Advantages | Disadvantages |
|---|---|
Increased efficiency | Job losses |
Increased accuracy | Potential for biased decision making |
Scalability | Ethical concerns over its use |
Extended Reality (XR)
What is extended reality?
Extended reality is an emerging technology that involves blending the virtual and real worlds together to create immersion for a user
Popular examples of extended reality are:
Virtual (VR)
Augmented (AR)
Virtual reality
Virtual reality is a technology that tries to shut out the 'real world' and immerse them in fully simulated environment
Virtual reality blocks out the 'real-world' by having users wear headsets with built in screens that provide a 360 degree view
Users are often able to interact with the virtual world through motion tracking
Augmented reality
Augmented reality overlays digital information or graphics into the 'real-world'
Users are not fully immersed and can still interact and see what is in front of them
Users view augmented reality via a smartphone or headset

Worked Example
Some smartphones connected to the internet can allow the user to point their phone’s camera at an object or image to display information about it on the phone’s screen. The object acts like an item in a search engine. This is called augmented reality.
One example of its use is in mobile games, where the user tries to catch characters from the game as the characters appear to walk in the streets. Explain, using examples, other ways in which augmented reality could be used in everyday life.
