Augmented reality (AR) applications enhance user engagement by overlaying digital information onto the real world, creating immersive experiences. These applications utilize devices such as smartphones or AR glasses to blend virtual elements with physical environments. By providing interactive features, such as 3D models or contextual information, AR can make user experiences more intuitive and engaging. This technology is widely used in sectors like education, marketing, and gaming, allowing users to visualize products, participate in simulations, or access interactive learning materials, which enhances retention and understanding.
