Media Integration for Aid of Intellectual Activities

本研究旨在创造媒介整合的应用，以协助资讯获取与理解、资讯传递或沟通、资讯呈现等智力活动，并建立媒介转换的基本理论，分析资讯符号描述或媒介表达规范的结构。后两个问题甚至以这样一种有些抽象的方式得到了解决：对媒体中包含的信息进行可逆的符号描述由两部分组成：一部分表示信息的内容，另一部分表示特定于媒体的表示信息。这表明，至少在符号描述中，媒体转换的理论解决方案是用替代媒体的描述取代对呈现媒体的描述。另一方面，每一种信息都有自己有利于人类感知和理解内容的形式或媒介。因此，在构建人类智力活动支持系统的过程中，关键问题是选择适合用户信息获取的媒体以及将一种媒体转换为所选择的媒体。本课题发展的理论为完成任务提供了一个基本的理论方案。应用这个想法，我们成功地实现了一个支持系统，用于理解地理信息，也用于操作ews上的文档，如参考文献中的文章所述。

This research project aimed to create applications of media integration to assisting intellectual activities such as information acquisition and understanding, information transfer or communication as well as information presentation, together with establishing fundamental theories for media conversion and analyzing the structure in a symbolic description of information or that of the specification of a media expression. The last two issues are solved even in such a somewhat abstract manner as follows : A symbolic description in a reversible way of information contained in a media consists of two parts : one of them represents the content of information and the other does the information for the presentation specific to a media.This indicates that a theoretical solution for media conversion at least in symbolic description is to replace the description for a presentation media by that for an alternative one.On the other hand, every kind of information has its own favorable forms or media to human perception and understanding of the contents. Consequently, in constructing support systems for human intellectual activities, the key issues are the selection of media appropriate to user's information capture of each part of contents and the conversion of a media to the selected one. The theory developed in this project offers a basic and theoretical scheme to accomplish the task.Applying the idea, we successfully implemented a support system for understanding of geographical information and also that for manipulating documents on EWSs as described in the articles in the references.
