    • In order to improve the accuracy of recognition of hand-written input using a stylus (1), output signals from a plurality of accelerometers representing x and y axis acceleration and deceleration are sampled at a predetermined rate and passed through a digital bandpass filter (7) to remove high frequency components and dc components arising from gravity. x and y vectors derived from the original x and y input signals are passed to a classifier using a hidden Markov model. Bandpass filtering improves the robustness of the interpretation of the vectors against stored templates which may be templates of individual characterisations or of whole words.
    • 为了提高使用触控笔(1)识别手写输入的精度,来自代表x轴和y轴加速度和减速度的多个加速度计的输出信号以预定速率被采样并通过数字带通滤波器(7 )去除重力产生的高频分量和直流分量。 从原始x和y输入信号导出的x和y向量使用隐马尔可夫模型传递给分类器。 带通滤波改善了矢量对存储的模板的解释的鲁棒性,可以是单个特征或整个单词的模板。

    • An image scanner and an optical character recognition device using the scanner are provided to scan only "intended areas" on a document, perform character recognition in the background, and input the results of recognition directly to an application. The image data obtained by scanning "intended areas" on a document by an image scanner (20) is converted into text data by a character recognition program in a personal computer (10) and input directly to an application program. Since the starting position to scan "intended areas" is specified and confirmed on an LCD (26) fitted to the image scanner (20), the operation is easy and reliable.
    • 提供了使用扫描仪的图像扫描器和光学字符识别装置,仅扫描文档上的“预期区域”,在后台执行字符识别,并将识别结果直接输入应用程序。 通过由图像扫描器(20)扫描文档上的“预期区域”获得的图像数据通过个人计算机(10)中的字符识别程序被转换为文本数据,并直接输入到应用程序。 由于在安装在图像扫描器(20)上的LCD(26)上指定并确认了扫描“预期区域”的起始位置,所以操作容易可靠。
