Augmented Reality (AR) is a technology that overlays digital information, such as images, videos, or 3D models, onto the real-world environment in real-time. Unlike Virtual Reality (VR), which immerses users in a completely virtual environment, AR enhances the physical world by adding digital elements. AR technology is commonly experienced through devices like smartphones, tablets, smart glasses, and AR headsets.
Push notifications are messages or alerts that are sent to a user's device from a server or application, even when the user is not actively using the app. These notifications appear on the device's home screen or notification center and can contain various types of information, such as news updates, reminders, promotional offers, or messages from friends.
Marketplaces are platforms where multiple third-party sellers can list and sell their products or services to a wide audience of potential buyers. These platforms facilitate transactions between buyers and sellers, often providing tools and services to support various aspects of ecommerce.
