摘　　要：触摸屏是常见的计算机输入设备,其数据处理方法直接影响了输入操作的准确性,特别用于文字手写输入时,其笔划数据的准确性直接影响到识别率。本文提出一种简单有效的提高触摸屏汉字笔划数据处理算法,即滤波、平滑和变换“三步法”,经过实验证明,可以提高汉字笔划输入数据的准确性。As a popular input device of computer system,touch screen provides a simple and convenience way for human-computer interaction. The input veracity is mostly depended on data disposing method. Especially, when a touch screen is useed for handwriting input, the input veracity plays an important role in character recognization. A data disposing algrithm of touch screen is proposed to improve the veracity. The algorithm can be divided into three steps, i.e. filtering, smoothing and transformation. The results of experiment show that it can improve the input veracity of Chinese strokes.
