项目摘要

As a research environment, we constructed a wide-area wireless network in Matsuyama city The wireless network is composed of ten wireless routers, and the area is few kilometers tip to tip. We examined a through-put to find the network is not stable and frequent packet-losses took place. We also constructed a wired network using campus network in Ehime University in order to compare the performances of the following applications with ones on the wireless network.As an assistance application for auditory difficulties, we constructed a movie transfer system, which provides us with real-time communication by sign languages. We examined file people whose main language is sign language. Through the reading tests, we found that 5 fps (frames/second) is enough to "read" most of sign language. This suggests that this frame rate is possible even on the wireless network as long as it is stable. However, it should be noted that comfortable sing language communication is possible with this frame r … More ate. We also constructed a character-based support system for those who don't use sign language. Voice recognition are included in this system and applied to some classes in Ehime University.We also constructed a remote Braille printing system based on WWW, e-mail and original server application. One simply drops a BSE (Braille format) file on the WWW page to print it out at the Ehime University The WWW page is designed for those with visual impairments. (Enhancements of characters and change of colors of characters or backgrounds are supported.) We also implemented a data convert filter program, which converts HTML format file to Braille lay-out file. One, who is unfamiliar with Braille language, can convert word-processor file to Braille using this filter via HTML format.Finally we developed a communication application for children with autistic spectrum disorder. Since this application are programmed based on Java applet, it does not require any special program, and works on any PC which is connected with the Internet. Less

作为研究环境，我们在松山市构建了一个广域无线网络，该无线网络由十个无线路由器组成，覆盖范围为几公里。我们检查了吞吐量，发现网络不稳定，经常发生丢包。此外，为了比较无线网络和爱媛大学校园网的性能，我们构建了有线网络。作为听觉障碍的辅助应用，我们构建了一个电影传输系统，它为我们提供了手语的实时通信。我们调查了以手语为主要语言的人。通过阅读测试，我们发现5帧/秒的速度就足以“阅读”大部分的手语。这表明，只要稳定，即使在无线网络上，这种帧速率也是可能的。然而，应该注意的是，舒适的歌唱语言交流是可能的，这一框架r ...更多信息吃过了我们还为那些不使用手语的人构建了一个基于字符的支持系统。该系统包括语音识别功能，并应用于爱媛大学的部分班级，还构建了一个基于WWW、电子邮件和原始服务器应用程序的远程盲文打印系统。人们只需将BSE（盲文格式）文件放在WWW页面上，然后在爱媛大学打印出来。WWW页面是为视力障碍者设计的。（支持字符的增强和字符或背景颜色的更改。）我们还实现了一个数据转换过滤程序，它将HTML格式文件转换为盲文布局文件。一个不熟悉盲文语言的人可以使用这个过滤器通过HTML格式将文字处理文件转换为盲文。最后我们开发了一个自闭症谱系障碍儿童的交流应用程序。由于该应用程序是基于Java applet编程的，因此不需要任何特殊的程序，并且可以在任何与Internet连接的PC上工作。少
