An information real-time synchronisation system across different media based on position encoding for mobile computing

In the education field, a typical scenario is that information must be synchronised across different media. Interactive paper system has been proved to successfully realise information synchronisation in real-time. However, existing solutions have some deficiencies such as poor reproducibility, delay in recognition, positioning error, not suitable for large-scale promotion and even expensive. In order to solve the problem of information fusion across different media at low-cost, an information real-time synchronisation system based on SONIX Code was designed and implemented innovatively in this paper, which redesigned the size of the code and code unit, and the decode algorithm . The experiments conducted on an A4 paper and a practical test among 350 users proved the system had good performance on visual effect, writing fluency and positioning accuracy.
