Construction of an intelligent work space with communications satellite networks and development of techniques of collaborative usage of it using an avatar language

研究结果如下：（1）为了进行构筑智能工作空间的研究，准备了利用通信卫星的网络环境，连接了北海道地区的主要大学，即包括KIT工学研究生院和水产科学研究生院在内的北海道大学的计算机系统。（北见工业大学）、HIT（北海道工业大学）和MIT（室兰工业大学）。(2)我们开发了一个新的概念“化身语言”在互联网上的化身技术，适用于建设一个智能工作空间，这些大学之间的合作研究上述。我们使用开发的技术进行了基础实验，例如CG技术的化身显示，使用化身语言的通信，通信卫星的图像传输，活体信息的传输，水印技术， 关于我们 通过通信卫星广播的教育节目、计算机辅助的音乐表演和使用网站的远程教育。(3)我们构建了一个基于知识处理的远程教育系统，假设一个由通信卫星连接的客户机-服务器系统。我们进行了实验，以估计开发的系统主要是在KIT，从而确认开发的系统的效率。(4)我们特别是哈工大的研究人员提出了一种新的移动的广播地球静止卫星的城市屏蔽和卫星分集特性的估计技术，以获得数据，为实际使用的通信卫星的化身通信在未来。(5)我们讨论了通过通信卫星广播内容的安全性。在MIT建立了一个邮件自动密码服务器的试验系统。(6)我们推动了e-Silkroad活动，这是在亚洲实现网络的新运动，我们帮助一家韩国公司在化身技术方面与日本公司联系。少

The research results are listed as follows ;(1) We prepared a network circumstance using communications satellite in order to conduct researches of constructing an intelligent work space, by connecting computer systems of major universities in Hokkaido area, that is Hokkaido University including graduate school of engineering and graduate school of fisheries sciences, KIT ( Kitami Institute of Technology), HIT ( Hokkaido Institute of Technology) and MIT ( Muroran Institute of Technology).(2) We developed a new concept of 'avatar language' in relation to the avatar technique in the Internet to apply to construction of an intelligent work space for collaborative researches among those universities listed above. We conducted fundamental experiments using the developed techniques, such as display of avatars by CG technique, communication using avatar language, image transmission by a communications satellite, transmission of information of living body, watermarking technique, monitoring of … More educational programs broadcasted by a communications satellite, computer-aided musical performance, and remote education using web site.(3) We constructed a remote education system based on the knowledge processing, supposing a client-server system connected by a communications satellite. We conducted experiments to estimate the developed system mainly in KIT, resulting in confirming the efficiency of the developed system.(4) We, especially the researchers of HIT, proposed a new estimation technique of urban shielding and satellite diversity characteristics for mobile broadcast geo-stationary satellite to obtain data for the practical use of communication satellite for avatar communication in future.(5) We discussed the security for broadcasting contents by a communications satellite. A trial system of an automatic cryptograph server for mail was constructed in MIT.(6) We promoted the event of e-Silkroad, which is a new movement to achieve a network in Asia, and we helped a Korean company to contact Japanese company in term of avatar technique.
