Facial expression-enhanced recommendation for virtual fitting rooms

With the development of Augmented Reality (AR) technology in the retail industry, virtual fitting room (VFR) are considered promising enhancement of e-commerce by providing users with an immersive environment to try on new products, especially fashion products. While allowing users having more vivid impression of products, virtual fitting rooms also offer sellers more channels to collect information on user preferences, which can be used to enhance recommender systems. This study proposes to leverage facial expression recognition technology together with fine-grained human-computer interactions in virtual fitting rooms to personalize product recommendations. This paper proposes a recommendation algorithm based on confidence setting, negative feedback sampling, and matrix factorization to model user behaviors in virtual fitting rooms. We conduct an experiment on 81 subjects to evaluate the proposed method. Experimental results show the proposed method outperforms existing methods using traditional behavior information. Our study provides a strong support to the value of AR in enhancing e-commerce.
