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）针对互联网中的虚拟形象技术，提出了“虚拟形象语言”的新概念，以实现一种非语言交流，其中虚拟形象的手势和情感表达使用CG（计算机图形）动画显示。(2)我们开发了一种新的编程语言Lifo，它是Lisp和Forth语言的后代，以实现Avatar语言的CG动画制作和显示的高速处理。(3)我们开发了一个CG系统，用于生成CG动画对应的话，从化身语言，以跨越语言障碍进行交流。一个服务器-客户端系统开发的化身语言通信使用开发的CG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，该系统的构建无需复杂的计算机编程，从而实现了简单的聊天系统。(5)在日本和韩国环境中的化身之间进行实验以使用化身语言进行通信，从而收集基本数据以在将来开发使用化身语言的非语言通信的实用系统。(6)使用日本通信卫星JCSAT进行通信实验，以确认开发的化身语言聊天系统的有效性。(7)我们提出了虚拟执行环境控制系统，以适用于通过通信卫星的化身语言通信，其中远程访问的响应性得到了改善。(8)提出了一种新的移动的广播地球同步卫星城市屏蔽和卫星分集特性的估计方法，为将来通信卫星虚拟通信的实际应用提供数据。

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.
