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)我们利用通信卫星准备了网络环境，通过连接北海道地区主要大学的计算机系统，即北海道大学包括工程研究生院和渔业科学研究生院，KIT（北美工业大学），HIT（北海道工业大学）和MIT （Muroran工业大学），进行构建智能工作空间的研究。(2)针对互联网虚拟化身技术，提出了“虚拟化身语言”的新概念，并将其应用于构建高校间协同研究的智能工作空间。我们利用开发的技术进行了基础实验，如利用CG技术进行虚拟形象显示、利用虚拟形象语言进行交流、利用通信卫星进行图像传输、利用活体信息进行传输、利用通信卫星进行水印技术、利用通信卫星进行监控等。(3)以通信卫星连接的客户端-服务器系统为例，构建了一个基于知识处理的远程教育系统。我们主要在KIT中对开发的系统进行了实验评估，从而确认了开发系统的效率。(4)针对移动广播地球静止卫星，提出了一种新的城市屏蔽和卫星分集特性估计技术，为今后通信卫星在虚拟通信中的实际应用提供数据支持。我们讨论了通信卫星广播内容的安全问题。在麻省理工学院建立了一个用于邮件自动加密服务器的试验系统。(6)我们推动了e-Silkroad的活动，这是一个在亚洲实现网络的新运动，我们帮助一家韩国公司联系了日本公司的化身技术。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.
