What are some things that are common in life, but are actually high in technology?

Some common things in life are actually high in technology. Here are some examples:

1. Mobile phone: The mobile phone is not only a communication tool, but also integrates many high-tech functions, such as wireless communication technology, touch screen technology, camera technology, artificial intelligence assistant and so on.

2. TV: Modern TV not only has high-definition display function, but also has intelligent operating system and network connection function, and can watch various contents through the Internet.

3. Computer: A computer is a powerful computing tool, which uses a microprocessor and an operating system to perform various complex computing and data processing tasks.

4. UAV: UAV is an aircraft that can fly autonomously. It uses advanced sensors and control systems, and can perform tasks such as aerial photography, logistics and distribution, and agricultural operations.

5. Self-driving cars: Self-driving cars use sensors such as lidar, camera and radar to perceive the surrounding environment, and realize the automatic driving function through artificial intelligence and autonomous control system.

6. Smart home equipment: Smart home equipment uses wireless communication technology and sensors to realize home automation, such as smart lights, smart door locks and smart speakers.

7. Virtual reality technology: Virtual reality technology brings users into a virtual environment through head-mounted displays and sensors, allowing users to experience various scenes on the spot.

These things are very common in daily life, but the technical content behind them is very high, involving the knowledge and technology of many disciplines.
