AI Technical Summary
Existing React Native solutions suffer from issues such as low real-time layout calculation efficiency, page lag, visual interference caused by fragmented text rendering, and coordinate system conflicts in synchronous voice and text display, especially on low-end devices.
The data preprocessing module groups and merges fragmented text by paragraph ID, pre-calculates the mapping index between text and audio time, uses a binary search algorithm for fast location, and switches between automatic and manual scrolling modes in the interactive control module, combined with exception handling and cross-platform adaptation optimization.
It significantly improves the scrolling positioning efficiency of low-end devices, reduces visual fatigue, enhances ease of operation and cross-platform compatibility, and optimizes the performance and interactive experience of synchronized voice and text display.
