The main application of augmented reality (AR) in retail is to enhance the shopping experience for customers. AR technology allows consumers to visualize products in their own environment, try on clothing virtually, or see how furniture fits in their homes before making a purchase. This interactive experience can significantly increase customer engagement and satisfaction, as well as reduce return rates. Retailers leverage AR to provide personalized recommendations and create unique marketing campaigns that capture consumers' attention, ultimately driving sales and fostering brand loyalty.
