What is commonplace in life, there are some things that actually have a high technological content. Here are some examples:
1. Cell phone: cell phone is not only a communication tool, it 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 a high-definition display function, but also has an intelligent operating system and network connectivity, which allows you to watch a variety of content through the Internet.
3. Computer: A computer is a powerful computing tool that uses microprocessors and operating systems to perform a variety of complex calculations and data processing tasks.
4. Drone: A drone is a flying machine that can fly autonomously, using advanced sensors and control systems to perform tasks such as aerial photography, logistics and distribution, and agricultural operations.
5. Self-driving cars: Self-driving cars use sensors such as LIDAR, cameras, and radar to sense the surrounding environment, and use artificial intelligence and autonomous control systems to realize self-driving functions.
6. Smart home devices: smart home devices use wireless communication technology and sensors to realize home automation, such as smart lamps and lanterns, smart door locks, and smart speakers.
7. Virtual Reality: Virtual Reality technology brings users into a virtual environment through head-mounted displays and sensors, allowing them to experience various scenarios immersively.
These things are already very common in daily life, but the science and technology involved behind them is very high, involving knowledge and technology from multiple subject areas.
