Augmented Reality (AR) is a technology that overlays digital information, such as images, videos, or 3D models, onto the real world as viewed through a device like a smartphone or tablet. In social media, AR is commonly used to create interactive filters, effects, and games that enhance user engagement and creativity. Brands leverage AR to offer immersive experiences, virtual try-ons, and interactive advertisements, blurring the lines between the physical and digital realms.
