Abstract Inputting written Chinese, unlike written English, is a non-trivial operation using a standard keyboard. To accommodate this operation, numerous existing phonetic systems using the Roman alphabet were adopted as a means of input while still making use of a Western keyboard. With the growing prevalence of computing devices capable of pen-based input, naturally sketching written Chinese using a phonetic system becomes possible, and is also generally faster and simpler than sketching… CONTINUE READING

Key Quantitative Results

  • With this new test data, our recognition system was able to achieve an accuracy rate of over 94%.
  • In regards to our recognition system’s accuracy rate of 94%, we found this to be quite reasonable for the set of MPS1 symbols.
  • While the accuracy rate of our system is not as high as the 95% and better accuracy rates for various vision-based system in the larger domain of Chinese characters, our approach can perfectly differentiate between positive and negative examples in terms of stroke order.
