Artificial intelligence (AI)
Artificial intelligence (AI) is a computer system that does tasks that normally need human thinking. Examples: recognising faces, understanding speech, making decisions.
Many AI systems learn from large amounts of data. The more examples they see, the better they get.
Uses: voice assistants, chatbots on shop websites, spotting fraud in bank payments, medical image analysis, self-driving cars.

Artificial intelligence (AI) (continued)
| Positive impacts | Negative impacts |
|---|---|
| Can work all day without tiring, so faster and more consistent | Can replace some jobs, causing unemployment |
| Can spot patterns in data humans would miss, e.g. early signs of disease | Only as good as its training data, so it can be biased or wrong |
| Can do dangerous or boring tasks | Expensive to develop; people may rely on it too much |

Extended reality: VR and AR
Extended reality (XR) is the general name for technologies that mix the real and computer-made worlds.
Virtual reality (VR) replaces the real world completely. The user wears a headset and sees only a computer-generated world. Sensors track head movement.
Augmented reality (AR) adds computer images on top of the real world. The user looks through a phone camera or smart glasses and still sees what is around them.

Extended reality: VR and AR (continued)
| Virtual reality (VR) | Augmented reality (AR) | |
|---|---|---|
| Real world visible? | No, fully replaced | Yes, with extra images added |
| Equipment | Headset, often with hand controllers | Smartphone, tablet or smart glasses |
| Example uses | Pilot and surgeon training, games, virtual tours of a museum | Seeing furniture in your room before buying, navigation arrows on a street, games like catching virtual creatures |
| Disadvantage | Can cause motion sickness; user cannot see real hazards | Needs a good camera and processing; drains battery |

Extended reality: VR and AR (continued)
Do not mix them up. VR = you are inside a virtual world. AR = virtual things are added to your real world.
