The term "augmented reality" refers to a technology that overlays digital information, such as images, sounds, or other data, onto the real world through devices like smartphones, tablets, or AR glasses. Unlike virtual reality, which immerses users in a completely digital environment, augmented reality enhances the user's perception of the actual world. This is achieved by using the camera and sensors of a device to blend digital content with real-world elements. Augmented reality has applications in gaming, education, training simulations, and retail, providing immersive experiences while retaining connections to the physical environment.
