摘要： A Chinese/Kanji on-line recognition system consisting of four main sections, these being tablet electronics, a signal filter and segment integration unit, a base stroke classification unit and a symbol element recognition unit, and a symbol recognition output table. The tablet electronics provides pen coordinate signals and pen up/down signals which are applied to the signal filter and segment integration unit to define segments of strokes which correspond to continuous motion of a pen on a tablet in a fixed direction. The base stroke classification unit classifies the motion of the pen between pen down and pen up occurrences into one of 42 categories and also indicates if the stroke has crossed a prior stroke. This is then analyzed by the symbol element recognition unit which interprets the base strokes that have been recorded for the word and generates a sequence of symbol elements, referred to as "alphabet" components, that occur in this symbol. The sequence of symbol elements are interpreted in the symbol recognition output table which provides a form of a simple table look-up to determine the word that had been written. Only 72 basic symbol elements (alphabet) are required to synthesize all of the Chinese/Kanji vocabulary.

摘要翻译： 中文/汉字在线识别系统，包括四个主要部分，分别是平板电子，信号滤波器和分段整合单元，基本笔划分类单元和符号元素识别单元，以及符号识别输出表。 平板电脑提供笔坐标信号和笔上/下降信号，其被施加到信号滤波器和段整合单元以定义对应于笔在固定方向上的平板电脑上的连续运动的笔画段。 基本笔划分类单元将笔的下移和笔触事件之间的运动分类为42个类别中的一个，并且还指示笔画是否已经越过了先前的笔画。 然后通过符号元素识别单元来分析，该符号元素识别单元解释已针对该单词记录的基本笔画，并生成在该符号中出现的称为“字母表”分量的符号元素序列。 在符号识别输出表中解释符号元素的序列，其提供了简单的表查找的形式来确定已经写入的词。 只需要72个基本符号元素（字母表）来合成所有的汉语/汉字词汇表。
