Alibaba Group debuted its first “FashionAI” concept store on Wednesday, demonstrating a stress-free way to shop with the help of artificial intelligence. The pilot store, open for a limited time only from Thursday through Saturday at Hong Kong Polytechnic University, showcases Guess apparel through innovations such as “smart mirrors,” which display product information on a nearby screen when shoppers are touching or picking up a garment. The smart mirror also makes mix-and-match recommendations and points to where the suggested items can be found in the store, so shoppers can try on a complete outfit at one go. In addition, each item has its own intelligent lock, supported by radio-frequency identification, gyro-sensors and Bluetooth low-energy chips. This allows the mirror to more accurately capture movement and spot the colors, styles and attributes that are most popular among customers.
