The best way to learn abstract knowledge in the initial phase is to liken it with some concrete illustrations. For example, we start acquiring literacy by using a picture storybook. Children notice the correspondence between the picture and the shape of the characters beside it first, and acquire literacy step by step. In this research, we aim to develop a new methodology and its supporting technologies for beginners to learn about computation and programming using the same step. We describe technical subjects for this system and build the 1st trial system.

We describe a design for a collaborative virtual learning environment (VLE) to support massively multi-user and multi-institutional learning communities. This architecture extends Croquet to encompass a tier of distributed cache servers that allow intelligent caching and pre-fetching of objects, scene definitions, and textures. The design also provides for interactivity servers tied to specific regions in the VLE. Interactivity servers provide persistence for neighborhoods, coordinate modification and transient phenomena for locales in the virtual space, and ensure trust relations by managing user identification, authentication, and authorization via integration with existing institutional authentication infrastructure. This system supports real-time interactions that promote a self organizing, interdisciplinary knowledge sharing system within a scalable VLE in a manner that ensures accountability and trust relations.

Development processes of embedded systems have been discussed many years and there exist number of advanced development environments. A well-designed development system may give us a unified design concept but such environment consists of components provided by a single vender in most case. A mixed-vendor environment can pick up nice feature of each system, however the coherency of concept and operation may be sacrificed. We discuss about unification of design process based on UML methodology. We are developing prototype of Squeak/Croquet based embedded system development environment in which mixed-vender design components are integrated in unified operation style.

We propose an operating mechanism for device cooperative content, which is a concept to provide new content on ubiquitous networks. There are two types of device cooperative content. The first is temporal synchronizing content and the second is semantical synchronizing content. Therefore, the content operation mechanism consists of two types of cooperative operation. Device cooperative playing plays various content synchronously after distributing user profile information to other accessible devices in setting up a cooperative playing environment. Device cooperative browsing is an interactive method, which can be used to browse related content for being content watched. Both operation mechanisms are based on multi-device operation, which are connected to a peer-to-peer network; the former operates cooperatively to find its own interests and maintains these around itself, the latter is a synchronous multi-device player. Multi-devices sharing common information might have common interest topics on various user devices. When new devices are connected to the environment, they detect suitable information through filtering, and obtain this from other devices on a local ubiquitous network. We describe this concept and discuss the device cooperative SMIL player and WebBoard, which are implementations of our concept.

This work presents the lifestyle of a "dream university" of the future, digitalized out of a real university campus. This "dream university" is actually a multipurpose digital campus facilitating for a better e-learning environment as the core of the research. It is an elaborate digital campus created with virtual collaborative environment in 3D system in the virtual world where users can learn and experience the campus life of the university while collaborating with other users involved. We propose all the available features that the digital campus can provide and discuss the points that have been proven to be advantageous for the users. Our goal is to create a dream university on the Web so that anybody can participate anytime, anywhere, depending upon his/her needs, removing all the barriers and solving problems involved in the real university.

This work presents an extension to the existing multilingualization work (ml7n) which allows people to collaborate on Squeak Etoy projects across different natural languages. Squeak etoys support several languages, both ISO-Latin based ones (erg., English, German, French), and nonISO languages (e.g., Japanese). Switching between languages for the Etoy tiles is fairly easy to support as the tiles provide a predefined set of words and phrases, which only need to be translated once. There are two areas where we need to go beyond the predefined and pretranslated set of phrases: user supplied names and communication between collaborators. This work presents an approach based on online translation services. We demonstrate a working prototype and a first analysis of the feasibility of this approach.

Summary form only given. In order to discuss experimental results or simulation results in the joint research between remote locations, it is indispensable to share visualization results (collaborative visualization). The Center for Promotion of Computational Science and Engineering of Japan Atomic Energy Research Institute (CCSE/JAERI) has performed the research and development of the visualization system having such a function in the Information-Technology-Based Laboratory (ITBL) project. The ITBL project aims to construct the virtual research environment which shares intellectual resources such as the remote computers, the programs and data in Japanese research institutions and supports joint researches between remote locations. Six institutions have joined as initial project members: National Institute for Materials Science (NIMS), National Research Institute for Earth Science and Disaster Prevention (NIED), Japan Aerospace Exploration Agency (JAXA), the Physical and Chemical Research Institute (RIKEN), Japan Science and Technology Agency (JST) and Japan Atomic Energy Research Institute (JAERI). In this project, CCSE/JAERI has developed the ITBL infrastructure software. An environment for operating the infrastructure software is composed of user terminals, ITBL servers and supercomputers. The infrastructure software offers a communication and security service, an application development service, etc. In the communication and security service, the communication function which can coexist with a firewall has been constructed using HTTPS protocol. Moreover, in the application development service, various services to share intellectual resources and support joint researches are constructed. The visualization system is positioned as one of these services. CCSE has developed two visualization systems: the parallel tracking steering (Patras) ZITBL and the application visualization system (AVS)/ITBL.

This work proposes Cooking Studio, a cooking support system for cooking novices. First, we describe a method to generate cooking scenario from Web recipe by morphological and semantic analysis, which is a basic document to represent cooking processes specifically in the system. We also provide cooking scheduling algorithm that maps the graph that represents cooking processes into a time chart to satisfy given restrictions. We also show a prototype system of Cooking Studio.

We reached a consensus that the main factor behind the current decline in community power might be the rapid deterioration in the volume and quality of communication within the community, as it sees its common conventions and goals being lost. Our research revealed that "children, women and the aged", while thought generally to be the key players in community revitalization, were also unfortunately perceived as being on the isolated side of the digital divide. Based on these premises, we set a common goal for the internal community as a whole, i.e., "to inculcate children with a sense of the community's responsibility". By assisting in the development of educational programs with which it was involved, this began to lead to the establishment of common agreement. For the following period of around a year, during the "Periods for Integrated Study" at a municipal elementary school, we implemented "the development of curricula and environments to enhance child creativity and problem-solving skills without requiring special personal or financial resources" through the use of IT.
