Design Principles and Practices for Mobile User Interfaces in High-Fidelity Virtual Reality Environments

With the continuous development of virtual reality (VR) technology, high-fidelity VR environments are increasingly applied in fields such as education, healthcare, and entertainment. As the primary mode of interaction between users and virtual environments, mobile user interfaces (MUI) play a crucial role, where the design’s effectiveness directly impacts user immersion and operational efficiency. However, most current MUI designs rely on 2D interface design principles, lacking a tailored design framework for 3D VR environments. In particular, in high-fidelity VR environments, user interaction demands exhibit high dynamics and individuality, which presents challenges for traditional design methods that struggle with adaptability. To address this, this paper first proposes design principles for MUI in high-fidelity VR environments, aiming to provide theoretical guidance and a practical framework for interface design in this field. Secondly, the paper investigates an anchor-point matching method based on simultaneous localization and mapping (SLAM) to solve the dynamic matching problem between user position and interface elements in VR environments. The study shows that by integrating SLAM technology, the accuracy and smoothness of user interaction can be significantly improved. This study enriches the theoretical foundation of user interface design in VR and offers developers more efficient and flexible interaction approaches.
