We have developed a pen-based Japanese character input system for the visually disabled persons, especially persons with acquired blinds. This system is composed of a character input tablet, a voice synthesizer and character recognition system. The main purpose of this system is to be applied to an electronic mail system for the blind persons. The results we got in this grant term are as follows:(1) Data base construction of the handwritten characters 3216 categories of Japanese characters, totally about 100 thousand characters were gathered from visually disabled persons and blindfold persons.(2) Enhancement of on-line character recognition algorithm Before we started this project, we had already developed an recognition algorithm for about 1000 category Japanese characters (Kyoiku Kanji Category). We enhanced this algorithm to apply 3216 category Japanese characters, including JIS No. 1 level Chinese characters, Hiragana, Katakana, Symbol, Alphabet.(3) Selection of the error correction algorithms of characters by word level knowledge. Three kinds of error correction algorithm were comparatively applied and evaluated. As the result, the Trigram method was found to be a best choice for our purpose.(4) Prototype of man-machine interface device We developed a prototype of man-machine interface device. This device is composed of an electric tablet for writing a character by the right hand, a hand controller for controlling the system condition by the left hand.(5) Document control system for visually disabled persons Document control system in CPU, like file management, document editing, and e-mail receiving/transmitting, was developed.

我们已经为视障人士，尤其是有盲人的人开发了一个基于笔的日本角色输入系统。该系统由字符输入平板电脑，语音合成器和字符识别系统组成。该系统的主要目的是将其应用于盲人的电子邮件系统。我们在本授予术语中获得的结果如下：（1）手写字符的数据基础构建3216个日语字符类别，从视觉残障人士和眼罩的人群中收集了大约1万个字符。（2）在我们启动这个项目之前，我们已经开发了一个公认的Algorithm angoriki a agan a agan kanj kan Jy（2）在线角色识别算法的增强（我们已经开发了一个公认的algoriki kan）（kanjory kan）。我们增强了该算法以应用3216个类别的日语字符，包括JIS No. 1级中文字符，Hiragana，Katakana，symber，Alphabet。（3）通过单词级别的知识选择字符的错误校正算法。相对应用和评估了三种误差校正算法。结果，发现Trigram方法是我们目的的最佳选择。（4）Man-Machine接口设备的原型我们开发了Man-Machine接口设备的原型。该设备由用于用右手编写角色的电平台组成，用于通过左手控制系统条件的手部控制器。（5）开发了用于视觉残障人士的文档控制系统文档控制系统，例如CPU中的文档控制系统，例如文件管理，文档编辑和电子邮件接收/发送/发送电子邮件。
