AR Emoji is a feature available on Samsung devices that creates an animated version of yourself that can be used to record your movements and facial expressions. It is a type of augmented reality (AR) technology that allows you to view your avatar in the real world through your camera and animate it with your facial expressions in real-time. You can customize your AR Emoji by choosing different hairstyles, outfits, and other features. Once you have created your AR Emoji, you can use it to make custom emoji, stickers, GIFs, and send them to people. To use AR Emoji, you need to launch the camera app and tap on the AR Emoji option. It is important to note that AR Emojis are only available on specific Samsung devices and some movements or expressions may not be recognized.
