Research on Development of Incorporating BanierFree into Mathematical Educations on the Network

我们一直在研究改善一个环境，让视力残疾的人可以在Web上自由地访问由MathML编写的科学和数学材料。为了在MathML的数学表达式中加入无障碍功能，我们开发了‘MathML Proxy’，这是一个在浏览器上表示数学公式的界面。该程序是将主页中包含的MathML改变为可访问形式的代理服务器。其功能如下：(1)在作为代理的Web服务器之间调停浏览器，(2)向Web服务器请求内容，(3)将从Web服务器接收到的包含内容的唯一MathML翻译成可访问形式，(4)将翻译后的内容输出到浏览器。使用在Windows系统上运行的现有屏幕阅读器，几乎可以在浏览器上朗读数学公式，并且在浏览器上表示数学公式的图像，我们调整了数学公式数据库，以便能够在网上浏览，然后在URL http：//pegasus上打开它。盖亚。JCN.倪汉宇。交流电。我们开发了CGI程序来编辑和上传公式数据库或由数学编辑人员(如Infty编辑器等)创建的教材。在开发输入/输出界面和数学材料阅读宏的过程中，我们制作了日语版的Chatty Infty和英文版的Infty，并在Infty编辑器中增加了语音系统。在未来，随着技术的发展，我们将继续研究一种更无障碍的浏览器。

We have studied to improve the environment that a visually disabled person can freely access to science and mathematics materials written by MathML on the Web. To incorporate barrier-free in mathematical expressions by MathML, we developed the 'MathML Proxy' that was an interface expressing mathematical formulas on a browser. This program is a proxy server changing a MathML included in homepages for an accessible formIts function is following that(1) Intermediating a browser between a web server as a proxy,(2) Making a request to a web server for contents,(3) Translating an only MathML which is contained the contents received form web server into an accessible form,(4) Putting translated contents out to a browser.It is almost possible to read mathematical formulas aloud on a browser, using the existing screen reader running on windows system, and to express image of mathematical formulas on the browser not showing MathMLOn constructing educational contents, we adjust the database of mathematical formulas enabling to browse on the web.And we open it on URL http : //pegasus. gaea. jcn. ni hon-u. ac. j p.We develop the CGI program editing and uploading the formula database or the teaching material created by a math editor (Infty editor, etc).On developing an input /output interface and a macro of reading mathematical materials, we made the Japanese version 'Chatty Infty' and English version one adding a speech aloud system to 'Infty Editor'. In future, evolving the technique, we proceed to investigate a more barrier-free browser.
