| 摘 要： | 遵循泛化计算理论，设计实现了一个联机手写公式编辑系统，以提高识别率和交互(效)率．该系统采用上下文感知技术来辅助切分、解决符号的二义性；采用备选择优、直接指定技术来修正字符的识别结果；采用局部放大解决笔画交叉时的分割问题；最后还给出一个补笔算法．实验表明，这些技术的应用使得数学公式的识别率和系统交互(效)率得到有效的提高，同时使该系统具有自然、隐式交互的特点。

| Abstract: | An on line handwriting mathematics editing system in pursuance of ubiquitous computing theory and improving the recognition rates and interaction rates is designed and implemented In this system, we applied context aware technique to help segmentation and resolve the ambiguity meaning of characters, applied best choice and direct assignment method to correct the recognition results, applied local magnification to segment the adjoining strokes, and eventually provided an algorithm for supplementing strokes As we can see from experiments, the recognition rate and interaction rate are improved effectively by applying these techniques At the same time, the system shows natural and implicit interaction features |
