Research and Application System Design of a Lightweight Mobile Augmented Reality Scene Creation and Experience Methodology

As a key development direction of human-computer interaction, Augmented Reality (AR) technology is faced with challenges such as high user experience requirements, high R&D costs, and insufficient terminal lightweighting. Smartphones as the platform for augmented reality applications, offering convenience, interactivity, and an excellent visual experience. Based on this, this paper proposes a lightweight Mobile AR scenario construction and experience method for mobile terminals and completes the design and development of the application system. The system adopts AR stereoscopic recognition technology to achieve feature extraction and matching, spatial positioning, and real-time rendering, and based on the WeChat Mini Program, a collaborative processing architecture for the server and the client is established, completing the full process spanning from scene creation, resource uploading, and mapping management to AR rendering. This study provides a viable technological approach for the popularization of lightweight augmented reality technology.
