Application of Virtual UI Interface Design Based on Mobile Terminal App Products

With the improvement of mobile communication network infrastructure and the popularization of intelligent mobile terminal equipment, mobile terminal equipment is gradually replacing other network equipment. According to statistics, 127 million Internet users in China only use mobile phones, accounting for 18.5% of the total Internet users. Mobile terminal devices have become an indispensable part of people's mobile social life. Mobility is an important trend of Internet development, which provides necessary conditions for the wide application of big data. Combined with the relevant theories of design psychology, ergonomics and user experience, this paper expounds how to carry out the workflow of prototype generation of mobile terminal app products and testing, using the methods of literature research and case analysis, explores the method of visual design application based on mobile terminal interface, and discusses the application of virtual UI interface design from three aspects: the specification requirements of human-computer interaction, information architecture optimization, the visual expression elements of interface, in order to provide reference for innovative design theories of mobile terminal app products. It plays a positive role in improving the theoretical system of the development of mobile Internet industry.
