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

我们一直在研究如何改善视觉障碍者可以在Web上自由访问MathML编写的科学和数学材料的环境。为了通过MathML将无障碍纳入数学表达式，我们开发了“MathML代理”，这是一个在浏览器上表达数学公式的接口。该程序是一个代理服务器，它将主页中包含的MathML转换为可访问的形式，其功能如下：（1）在作为代理的Web服务器之间中介浏览器，（2）向Web服务器请求内容，（3）将从Web服务器接收的内容中包含的唯一MathML转换为可访问的形式，（4）将翻译后的内容输出到浏览器。几乎可以使用运行在Windows系统上的现有屏幕阅读器在浏览器上大声朗读数学公式，并在不显示MathML的浏览器上表达数学公式的图像。我们调整了数学公式数据库，使其能够在Web上浏览。我们在URL http：//pegasus上打开它。盖亚jcn。你好。AC. jp.开发了CGI程序，用于编辑和上传由数学编辑器（Infty编辑器等）创建的公式数据库或教材，在开发输入/输出接口和阅读数学教材的宏的基础上，制作了日文版“Chatty Infty”和英文版“Infty编辑器”，并在“Infty编辑器”中增加了语音朗读系统。在未来，不断发展的技术，我们着手研究一个更无障碍的浏览器。

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.
