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

我们已经研究改善环境，使视障人士可以在Web上自由地访问由MathML编写的科学和数学材料。为了将MathML无障碍地集成到数学表达式中，我们开发了“MathML代理”，这是一个在浏览器上表示数学公式的接口。这个程序是一个代理服务器，将包含在主页中的MathML更改为可访问的形式。它的功能如下：(1)作为代理在web服务器之间充当浏览器的中介，(2)向web服务器发出内容请求，(3)将包含从web服务器接收到的内容的唯一MathML转换为可访问的形式，(4)将翻译后的内容发送给浏览器。利用windows系统上现有的屏幕阅读器几乎可以在浏览器上大声朗读数学公式，并且为了在不显示MathMLOn构建教育内容的浏览器上表达数学公式图像，我们调整了数学公式数据库，使其能够在web上浏览。我们打开URL http: //pegasus。盖亚。jcn。倪hon-u。我们开发了CGI程序编辑和上传公式数据库或数学编辑器（Infty编辑器等）创建的教材。在开发输入/输出界面和阅读数学材料的宏方面，我们制作了日文版的《Chatty Infty》和英文版的《Chatty Infty Editor》，并在其中添加了语音朗读系统。在未来，我们将继续研究一种更加无障碍的浏览器。

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.
