Google is bringing AR Stickers later this year to its Pixel 2 and Pixel 2 XL phones that react to the other stickers as well as the world around them.
I got to see a demo of the new feature with Google’s Clay Bavor. He showed how you can place multiple AR stickers in a single space and size them to your liking. I saw, for instance, two versions of the demogorgon from Stranger Things. One was life size and the other stood action figure-sized on the table. He also placed Eleven from the show in the space and she immediately interacted with the creature. The lighting on the AR characters also adjusts dynamically as well, so the digital characters look more realistically inserted into the scene no matter the environment.
