Development of a non-verbal communication technique using signlanguage and live CG techniques and its communication experiment across different languages using a communications satellite

研究结果如下：(1)针对互联网上的虚拟化身技术，提出了“虚拟化身语言”的新概念，利用CG（计算机图形学）动画来显示虚拟化身的手势和情感表达，实现非语言交流。(2)开发了一种新的编程语言Lifo，它是Lisp和Forth语言的后代，实现了虚拟化身语言CG动画的制作和显示的高速处理。(3)为了跨越语言障碍进行交流，我们开发了一个CG系统，用于生成对应于虚拟角色语言单词的CG动画。利用开发的CG系统，开发了一个用于虚拟语言通信的服务器-客户端系统。(4)我们使用MATLAB软件工具构建了一个虚拟语言聊天系统，该系统的构建不需要复杂的计算机编程，聊天系统非常简单。(5)在日语和韩语环境下的虚拟人物之间进行了虚拟人物语言交流实验，为将来开发虚拟人物语言非语言交流的实用系统收集了基础数据。(6)利用日本通信卫星JCSAT进行通信实验，验证了所开发的虚拟语言聊天系统的有效性。(7)提出了虚拟执行环境控制系统，应用于通过通信卫星进行的虚拟化身语言通信，提高了远程访问的响应能力。(8)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，为未来通信卫星的虚拟通信实际应用提供数据支持。

The research results are listed as follows ;(1) We proposed a new concept of 'avatar language' in relation to avatar technique in the Internet to realize a non-verbal communication, where gestures and emotional expressions of avatars are displayed using CG (computer graphics) animations.(2) We developed a new programming language Lifo, which is a descendant of Lisp and Forth language to achieve high-speed processing in producing and displaying CG animations of avatar language.(3) We developed a CG system for generating CG animations corresponding to words from avatar language in order to communicate across the linguistic barrier. A server-client system is developed for avatar-language communication using the developed CG system.(4) We constructed an avatar-language chatting system using a software tool : MATLAB, where the system is constructed without complicated computer programming, resulting in simple chatting system.(5) An experiment was conducted between avatars in Japanese and Korean environments to communicate using avatar language, resulting in collecting a basic data to develop a practical system of a non-verbal communication using avatar language in future.(6) A communication experiment using Japanese communication satellite JCSAT was conducted to confirm the validity of the developed avatar-language chatting system.(7) We proposed the virtual execution environment control system in order to apply to the avatar language communication via communication satellites, where responsiveness for the remote access was improved.(8) We 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.
