**Augmented reality (AR)** is primarily used for enhancing the user's interaction with the real world by overlaying digital information onto physical environments. It enables applications in various fields, including **gaming**, education, retail, and training. For instance, AR can provide users with interactive experiences such as trying on clothes virtually or visualizing furniture within their home space. By bridging the gap between the virtual and physical worlds, AR enhances user participation and can lead to greater customer satisfaction and engagement.
