The huge, American-based technology show CES has changed in recent years because of the COVID-19 pandemic.
Last year, an online version of the event was held for the first time.
This year, the physical show returned to Las Vegas, Nevada. But the number of attendees decreased by about 70 percent. In addition, several major technology companies suddenly decided to pull out, The Associated Press reported.
CES is produced by the Consumer Technology Association. It is known as the place where many companies launch their latest technology offerings. Here is a look at some of the top products presented at CES 2022.
Taiwanese computer maker ASUS announced the launch of a foldable laptop computer. It is called the Zenbook 17 Fold. While several companies have already launched foldable versions of phones, the idea has not yet caught on with laptop computers.
中国台湾电脑制造商华硕公司发布了一款可折叠笔记本电脑。它就是Zenbook 17 Fold。虽然已经有数家公司推出了可折叠手机，但是这个想法在笔记本电脑上尚未流行开来。
The company says its new device is a powerful personal computer, or PC, with a high-quality OLED display that is about 44 centimeters across. But it folds down to about 32 centimeters for easier transport.
Electronics maker AirSelfie launched its latest self-flying camera designed to take "selfie" pictures. The new device, called Air Pix, is a small, light camera that flies through the air and captures high-quality photographs and video. A video on the company's website explains that Air Pix can fly, frame and take pictures all by itself before landing back on the user's hand.
电子产品制造商AirSelfie推出了用于自拍的最新款自动飞行相机。这款名为Air Pix的新设备是一款小巧轻便的相机，它可以在空中飞行并拍摄高质量的照片和视频。该公司网站发布的一段视频解释说，Air Pix可以自行飞行、构图并拍照，然后降落到用户手中。
Technology company Anker announced the launch of an "all-in-one" device designed to improve communications for employees working from home. The AnkerWork B600 sits on top of the computer display like a traditional webcam. But it combines several elements of communication into one device that includes a camera, speaker, microphone and a light.
Robotic Wi-Fi router
TP-Link showed off a new Wi-Fi router that the company says uses robotic antennas to find and lock onto the best wireless signals to improve internet speeds and performance. Images of the Archer AXE200 Omni device show its motorized antennas rising, falling and changing positions in search of strong signals.
TP-Link公司展示了一款新的无线路由器，该公司称该路由器采用自动调节天线来寻找并锁定最佳无线信号，以提高互联网速度和性能。这款Archer AXE200 Omni设备的影像显示了它的电动天线升降和改变位置以寻找最强信号。
Labrador's assistive robot
Robot maker Labrador announced the launch of its Retriever robot. CES has historically been known to present different kinds of robots, including many designed to look and act like people or animals. But Labrador says its Retriever robot was designed to be truly useful in helping those who need assistance at home.
The small, self-driving machine is designed to hold things and, as its name suggests, also retrieve things. The robot can be controlled by voice commands or from an app on a phone. It can also be programmed based on an exact map of a user's home. The company says the Retriever is designed "to serve as an extra pair of hands and lighten the load of everyday tasks in the home."
Samsung Odyssey Ark
South Korean electronics maker Samsung is known for announcing major new products at CES. Many involve bigger television sets with new abilities. This year, the company presented several new computer displays meant to serve people who play video games, known as gamers.
One of them, called the Odyssey Ark, has a curved design and measures nearly 140 centimeters. Samsung demonstrated how the huge display can also be turned on its side, to curve right above the user's head for a more intense gaming experience.
American-based farm equipment manufacturer John Deere presented a fully self-driving tractor. The company says the vehicle is equipped with six different cameras and a series of sensors to guide the tractor through the fields. Farmers can control the vehicle and see the tractor's progress in real-time through a mobile device. John Deere says the idea is to help farmers do more work with less equipment and people.
The company noted that such machines can help improve farming methods as the world's population grows and food demand is expected to rise 50 percent by 2050.
