①Hangzhou, together with five other cities in Zhejiang, hosted the 19th Asian Games from September 23rd to October 8th The Games are very “smart” with the use of many exciting technologies. Let’s have a look!

②Every dish at the Asian Games should be safe and healthy to eat. In the kitchen of the athletes’ (运动员) village in Hangzhou, there is a special system (系统) that can tell people’s faces. If a “stranger” goes into the kitchen, an alarm will go off to let people know. The managers of the kitchen will also get messages on their phones. There’s also a system to keep an eye on the temperature of the fridges.

③Want to walk around at the stadiums (场馆) but can’t make it in person? You can try the Asian Games’ metaverse! It’s a mini program (程序) on Alipay. It’s like an online cartoon world. You can see the stadiums both from the outside and inside. Also, you can have your own character in the metaverse. You can choose clothes for your character who is able to “run” around the stadiums and talk with other online users.

④Say that you are in Hangzhou and going to watch one of the events. It will be sad if you can’t find your way. Augmented Reality (AR) is here to help. There’s a mini program called the Hangzhou Asian Games AR service. You simply turn on your phone’s camera and it will see where you are and then show you the way. You can also get more information about the stadiums as you walk by.

y = sin x, x∈R, y∈[–1,1],周期为2π,函数图像以 x = (π/2) + kπ 为对称轴
y = arcsin x, x∈[–1,1], y∈[–π/2,π/2]
sin x = 0 ←→ arcsin x = 0
sin x = 1/2 ←→ arcsin x = π/6
sin x = √2/2 ←→ arcsin x = π/4
sin x = 1 ←→ arcsin x = π/2
