A Novel Position-based VR Online Shopping Recommendation System based on Optimized Collaborative Filtering Algorithm

This paper proposes a VR supermarket with an intelligent recommendation, which consists of three parts. The VR supermarket, the recommendation system, and the database. The VR supermarket provides a 360-degree virtual environment for users to move and interact in the virtual environment through VR devices. The recommendation system will make intelligent recommendations to the target users based on the data in the database. The intelligent recommendation system is developed based on item similarity (ICF), which solves the cold start problem of ICF. This allows VR supermarkets to present real-time recommendations in any situation. It not only makes up for the lack of user perception of item attributes in traditional online shopping systems but also VR Supermarket improves the shopping efficiency of users through the intelligent recommendation system. The application can be extended to enterprise-level systems, which adds new possibilities for users to do VR shopping at home.
