Snapchat is one of the first applications to provide ar experience with iPhone 12 Pro lidar sensors, followed by tiktok , a popular short video application. In the first AR special effect launched, it provided a ball similar to the ball that fell on Times Square across the University. After the countdown, it would "explode", and then hang "2021" in the air and release colored paper.
From the actual effect, there is no difference between the falling effect of the colored paper released after the explosion and the real colored paper. After people move away, the colored paper will fall further under the influence of gravity. Tiktok said that due to the interaction between AR effect and user environment, it can visually connect the digital world and physical world.
