项目摘要

An assistive system for the blind was developed and completed. It enables the Java programming by tactile and hearing methods. This system consists of the three sorts of software shown below.Each of them has the function to output braille onto a Braille display terminal, and works without suppressing the speech output of the screen reader in use.1. Text editor :In addition to the basic functions required for editing text data, it has the functions to cooperate with Java compiler. It also informs the user of the current location (line number and method name) of the cullet when requested. The outlining function shows the structure of the Java source program currently edited.2. Alternative command prompt :It enables a blind user to operate the Windows system in command line mode. He/she can read character strings on the screen such as input command, execution result, system message etc. by means of Braille display terminal and speech output.3. Front processor for compiler :It is operated in command line mode in the same way as the Java standard compiler javac. But if any error is detected, a window is opened to display the error list. Choosing one of the item in the list, the line of source code in which the error occurred can be directly accessed through the text editor.The result of an experimentation showed that the system worked properly and was enough useful to help the blind in practicing Java programming.

开发并完成了一个盲人辅助系统。它使Java编程的触觉和听觉的方法。该系统由以下三种软件组成，每种软件都具有将盲文输出到盲文显示终端的功能，并且不抑制屏幕阅读器的语音输出。1.文本编辑器：除了编辑文本数据所需的基本功能外，还具有与Java编译器配合使用的功能。它还在用户请求时通知用户碎玻璃的当前位置（行号和方法名称）。大纲功能显示当前编辑的Java源程序的结构。替代命令提示符：它使盲人用户能够在命令行模式下操作Windows系统。他/她可以通过盲文显示终端和语音输出读取屏幕上的字符串，如输入命令、执行结果、系统消息等.编译器的前端处理器：它以命令行模式运行，与Java标准编译器javac的方式相同。但如果检测到任何错误，则会打开一个窗口以显示错误列表。选择列表中的一项，通过文本编辑器可以直接访问出错的源代码行。实验结果表明，该系统工作正常，对盲人学习Java编程有一定的帮助。
