Development of support system for educational telecommunication network

培养适应国际社会的人才需要英语能力和沟通能力。然而，在非英语母语人群的语言学习交流中，语言墙是很高的。本研究旨在建构顺畅通讯之教育支援工具。利用通信网络进行远程交换，克服了距离的限制，适合于国际间的连续交换。特别是在学生之间的交流中，他们的积极性大大提高。日本学生在跨文化交流中有很大的优势，主要由于他们的文化背景，他们倾向于不尝试说出自己的观点。解决这个问题的第一步是准确把握会议的讨论主题。对于没有进行过很多英语国际交流实验的学生来说，语言支持对于充分理解内容是必要的。在本研究中，我们提出了一种在电信领域使用…More keywords的方法，让主讲人持有关键词，观众看到的是带有翻译、图像、3D模型等附加信息的关键词。期望学生能够理解内容，在讨论中阐明主题或论点。为了实现所提出的方法，我们开发了一个原型系统，通过增强现实技术，检测远程站点之间交换的图像中的关键词，并呈现相关信息，如翻译，图像，3D模型和声音。该系统由服务器和客户端组成，考虑到一位老师和多名使用不同母语的学生之间的通信。我们也做了提高准确性的字符识别系统的稳定性，多样化的语言类型呈现的关键字，为不同的学生。我们还研究和总结了有效处理电信多媒体内容的交互技术。少

Bringing up talents who cope with international society requires English abilities and communication skills. However, the language wall is high in the language learning exchange between people with non-English mother tongues. This research aims to construction of an educational support tool for smooth telecommunication.Remote exchange with communication networks is suitable for continuous international exchange because of overcoming the distance. Especially, in the exchange between students their motivation is improved greatly. The Japanese students have large handy in the intercultural exchange, having tendency not to try speak their own opinions mainly due to their cultural backgrounds. The first step to solve this problem is to grasp the discussion topic or theme exactly in the session. The language support is necessary for sufficient comprehension of the content for the students who do not have many experiments of international exchange in English. In this research, a method using … More keywords in telecommunications is proposed, so that a presenter holds keywords and the audience see the keywords with the additional information such as translation, image, and 3D models. It is expected that students can understand the content, clarifying the theme or the contention in the discussion.To realize the proposed method, we developed a prototype system by applying augmented reality technology, detecting keywords in images exchanged between remote sites and presenting the related information such as translation, images, 3D models, and sounds. The system consists of server and clients, taking account of telecommunication between a teacher and multiple students with different mother tongues. We also did improvement of accuracy on character recognition for system stability, and diversification of the sort of language presenting keywords for various students. We also investigated and summarized interaction techniques effectively dealing with multimedia content in telecommunications. Less
