Augmented reality (AR) is used in the retail industry to enhance the shopping experience by overlaying digital information onto the physical world. Retailers utilize AR applications to allow customers to visualize products in their own environments, such as seeing how furniture looks in their home or trying on clothing virtually. This technology not only engages customers but also helps reduce return rates by ensuring that purchases meet consumer expectations. Additionally, AR can provide interactive marketing experiences, making the shopping process more enjoyable and informative.
