　View Summary

We have developed an idea generation support system, called GUNGEN-Spiral. GUNGEN-Spiral supports collecting ideas, saving ideas, sharing ideas, shaping ideas and reusing ideas. The system consists of GMemo running on a Personal Digital Assistant(IBM WorkPad), Wadaman(Whole mediA DAta MANagement system), WWWW(World Wide Web Wadaman, W4)and GUNGEN(GroUpware for a New idea GENeration consistent support system). Users can collect and input ideas in free handwriting using GMemo immediately anytime and anywhere, and the ideas are saved in Wadaman and shared all together using W4 on the Internet. Moreover, participants use those ideas directly as data for GUNGEN. We can reuse the results of GUNGEN as topics for further ideas, and others' ideas sometimes give rise to new ideas. We have applied this system on a trial basis.

　View Summary

We have developed data collecting software, called GMemo(GUNGEN Memo), running on a Personal Digital Assistant(PDA). GMemo is a piece of input equipment foe GUNGEN. GUNGEN is a groupware for a new idea generation consistent support system. Users can collect data for the KJ method using GMemo easily with no omission, and input ideas in free handwriting. we thought that such sudden ideas need to be stored in anytime and anywhere. The feature of GMemo is using handwriting data as input data for GUNGEN directly. We requested members of the Wakayama University Information Science Center to use GMemo regularly. They have used GMemo for about five months. The kinds of collected data were about the improvement of centers works and the improvement of GMemo. We carried out KJ method using handwritten data collected by GMemo. In this paper, we describe the result of the data collection using GMemo and the result of KJ method using handwritten data collected by GMemo. Furthermore, we show the effectiveness of the data collection using PDA.

Transactions of Information Processing Society of Japan ( Information Processing Society of Japan (IPSJ) )  40 ( 11 ) 3946 - 3956   1999.11  [Refereed]

　View Summary

We have developed a distance learning support system called SEGODON for exercise-type classes, and applied this system to "Applied Mathematics Exercise" classes four times, continuously. The system consists of 40 personal computers, a workstation and inexpensive input equipment. A teacher can conduct an exercise-type class with students via a network. We developed a report submission system to conduct exercise-type classes. A student can submit a report to a teacher during class, and the teacher can mark the report and return it to the student. We have solved problems of applications to exercise-type classes and have developed the necessary functions for the "Applied Mathematics Exercise". We found the following results from these applications. (1) The distance learning class (exercise) using SEGODON was as effective for the students as the normal class (exercise). (2) We found that the treatment of reports was important in an exercise-type class. We found that the maximum number of submitted reports that could be checked by a teacher and a TA was approximately 70. (3) We found that special functions for the exercise, i.e., the expression input support palettes, were required.

Transactions of Information Processing Society of Japan ( Information Processing Society of Japan (IPSJ) )  40 ( 1 ) 150 - 160   1999.01  [Refereed]

　View Summary

We have developed a multi-user electronic conferencing system, named DEMPO III. DEMPO III is a text-based desktop electronic conferencing system for a face-to-face environment. This system was implemented in a network in our program-practicing room, consisting of 40 personal computers and one workstation. Most systems for multiple users have a chat function, but there are few real systems that can move opinion labels on the screen freely. We have developed an electronic conferencing system that can represent opinions among large numbers of people. The system has two distinctive methods, as follows: First, all recorded information is stored under a file name but not in file contents. Secondly, access from personal computers to the workstation is performed by the use of FTP at a constant interval. We have applied this system to actual conferencing 6 times with more than 10 people, and some functions, especially opinion labels freely moving function, have received a favorable reception by the users. The experiments using 40 computers showed the stable acquisition of data.

Transactions of Information Processing Society of Japan ( Information Processing Society of Japan (IPSJ) )  39 ( 10 ) 2788 - 2801   1998.10  [Refereed]

　View Summary

We have developed a supporting system for distance learning classrooms via Internet, which can consist of 40 personal computers and inexpensive input equipment. This system may support a classroom, in which a teacher lectures for students in a remote computer practicing room. In the teacher side, a picture of the classroom is always displayed by a remote control camera, and the upper half of the teacher's body is always seen on a screen in the classroom. For questions and answers a direct connection between the teacher and any student in the classroom can be set up for video and audio signals. Additionally, this system is equipped with shared cursors between a teacher and students, a blackboard system and a note system. Three kinds of distance learning classrooms have been tried; (1) between Osaka University and Kagoshima University, (2) between two buildings in Kagoshima University, and (3) within a computer practicing room. In these applications, it has been found that better understanding may be performed for students by this system.

　View Summary

Recently, it has been actively studied that a support system for advanced education that is mixed some of groupware, multimedia, and hypertext. However, being closely related them each other, it is necessary to build a software platform for computers. So, we have developed an educational platform named DEMPO II. DEMPO II consists of an electric conference system, a question-answer system, a progress report system, an e-mail system, a database with distribution link, a file system with 3D like visual interface, and a distributed computer managing system. We have used this system for programming exercises and we found various things. We describe merits, demerits, and future specification of DEMPO II in this paper.

　View Summary

A distributed multlmedia platform, DEMPO, has been developed for studying next generation of computer software environment. DEMPO consists of WildCard, Emc, and Wadaman. WildCard based on a desktop system manages the whole system and permits a 3-D screen display. Emc is an electronic meeting system having an extra function to take in chats on the way of meeting. Wadaman is an intellectual productive work support system based on HyperCard. DEMPO was implemented on a computer system for student education and applied to a programming exercise of students with satisfactory results.
