The term augmented reality (AR) refers to the technology that overlays digital information—such as images, sounds, and other data—onto the real world in real time. Unlike virtual reality that immerses users in a completely digital environment, AR enhances the user's perception of their physical surroundings by adding digital layers of content. This can be achieved through devices like smartphones, tablets, or dedicated AR glasses. AR applications are used across various fields, including gaming, education, and marketing, enriching user interactions with contextual information.
