AR, or augmented reality, is a technology that allows you to superimpose digital content on top of the real world. You can use AR to view 3D models of objects, play games, and even create your own AR experiences.
To use AR on your Galaxy Note 9, open the Camera app and switch to the AR Mode. Then point your camera at a flat surface and tap the screen to place a virtual object in your environment. You can move around and view the object from different angles, or even walk through it if it's transparent.
If you want to get really creative, you can even create your own AR experiences using Samsung's AR Emoji or Scene Maker features. With Scene Maker, you can add 3D characters and objects to your photos and videos, then share them with friends. And with AR Emoji, you can create a custom avatar that looks just like you (or anyone else) and use it in all kinds of fun ways.
