| Research Abstract |
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.
