MUNEMORI JUN, OHNO SUMIKA, YOSHINO TAKASHI

IPSJ journal ( Information Processing Society of Japan (IPSJ) ) 47 ( 7 ) 2071 - 2080 2006.07 [Refereed]

Pictographs have widely spread to add nuance to mails of mobile phones in Japan and foreign countries, e.g. China. We have developed a pictograph chat system, which can communicate each other using nothing but pictographs. We prepared 550 pictograph symbols. We applied the system for communication to 3 groups, which consist of the intimate friends group, the strangers group, and the Japanese students and foreign students group. The foreign students consist of Chinese (four persons), a Malaysian, and a Vietnamese. We have carried out experiences 18 times (six times in each experiment). We report the results of the experiments as below. (1) The subjects understood over 70% of the content of the very simple chat. (2) There seemed to be no difference between foreign students and Japanese students about the context of the chat and about the evaluation of the system. Japanese students tended to make the same context as foreign students. (3) Proper nouns should be prepared sufficiently. Proper nouns were used very well between intimate friends.

Development and Application of a Location-based Universal and Two-way Guide System xExplorer

MUNEMORI JUN, KAMISAKA DAISUKE, TRI THAI MINH, YOSHINO TAKASHI

IPSJ journal ( Information Processing Society of Japan (IPSJ) ) 47 ( 1 ) 28 - 40 2006.01 [Refereed]

There have been developed many guide systems using location information. But most of systems have one-way communication system. These systems don't aim to mutual communication between sightseers by information sharing. The two-way communication, such as a chat or exchanging digital files included photos, is a common sense in Japanese ubiquitous society. Therefore, we have developed a prototype universal guide system, which was named xExplorer. xExplorer has real-time information sharing functions including image data, a chat, and mutual location information. We applied the system to the streets in the southern bound of Osaka and the Palace museum in Beijing. Subjects were Japanese and Chinese. The results of experiments show below : (1) The evaluation of the image data sharing function was high in both Japanese and Chinese. Because they can share the others with view points in real timely. (2) The chat was used for not only communication but also explaining relating shared contents. Sometimes, the content of chat messages is about an image data. (3) The system should have a function that helps the correlation between image data and chats. Then, the image data, which is an object of chats, can be found easily. (4) It is necessary that image should be appended with other information such as the meeting point, etc.

MUNEMORI JUN, SHIGENOBU TOMOHIRO, MARUNO SHINJI, OZAKI HIROSHI, OHNO SUMIKA, YOSHINO TAKASHI

IPSJ journal ( Information Processing Society of Japan (IPSJ) ) 46 ( 1 ) 26 - 37 2005.01 [Refereed]

We have designed an intercultural teleconference system "RemoteWadaman III" and applied to presentations between Japan and China. RemoteWadaman III has the communication functions of text translation, a shared screen, shared pointers, a shared whiteboard, audio and video communication, a chat with pictograph. We use every function to understand about a presentation of partners. We carried out the experiment 8 times for measuring the effects of the multimedia support functions. We report the results of experiments as below. (1) The subjects thought that they understood about 70% of the content of the partner's presentation intuitively even if they didn't understand their partner's language. The rate of understanding was almost the same as they used English for discussion. (2) 59% of the sentence of chats has pictograph. Question mark and/or its pictograph existed about 17% of the whole sentence. 5% of the sentence consisted of only pictograph. These results suggested that pictograph could be used as supporting language of intercultural collaboration.

GUNGEN DX II : Idea Generation Support System with Grouping-labels Function for Hundreds of Labels

SHIGENOBU TOMOHIRO, YOSHINO TAKASHI, MUNEMORI JUN

IPSJ journal ( Information Processing Society of Japan (IPSJ) ) 46 ( 1 ) 2 - 14 2005.01 [Refereed]

We have carried out experiments using an idea generation support system, named GUNGEN, which supports the KJ method. We have used about one hundred labels in the experiments. Several hundred labels can improve the results of experiments in the KJ method. When we treat several hundred labels, we should understand all contents of them. We should equip a special function for understanding the content of labels. We have developed GUNGEN DX II, which has a special function for a lot of labels. We have carried out experiments using GUNGEN DX II. GUNGEN DX II have a special function named "the draft islands generating function" to support the KJ method which can handle hundreds of labels. The draft islands generating function supports the grouping-labels step of the KJ method by grouping labels easily. Each participant stacks similar labels dropping from the top of a window in order intuitively. The features of the function are to restrict a dropping time and to operate easily. The stacked labels of the same column become an island. Each participant performs the task individually. The function generates draft islands from the common part of each participant's islands automatically by majority decision. Participants make conclusive islands by correcting the arrangement of draft islands. We carried out the KJ method using hundreds of labels. We compared with results of experiments using GUNGEN. Even if the number of labels increased, the time required to group labels decreased about 30 percent.

Hajime Yoshida, Takashi Yoshino, Jun Munemori

Digest of Technical Papers - IEEE International Conference on Consumer Electronics ( Institute of Electrical and Electronics Engineers Inc. ) 159 - 160 2005

We developed a prototype of a chat system using sense of touch. Depending on the power of grasping a mouse, two kinds of face marks ((∧∧), (&gt
&lt
)) are inputted to the chat window. We applied this prototype to a kind of an electronic conferencing system, named a remote seminar support system. From the results of experiments, we found that the system was effective for transmitting the tension to participants. We think this approach can be applied to various types of communication, for example, interactive TV with excitement level of audience. © 2005 IEEE.

SHIGENOBU TOMOHIRO, NODA TAKAHIRO, YOSHINO TAKASHI, MUNEMORI JUN

IPSJ journal ( Information Processing Society of Japan (IPSJ) ) 45 ( 1 ) 255 - 266 2004.01 [Refereed]

We have developed a flexible lecture support system using PDAs and wireless LAN, named SEGODON-PDA. A conventional fixed lecture support system has been carried out only in the classroom such as a computer room. The problem is the trouble of management. PDAs are comparatively cheap and their portability is good. A flexible system can be built using PDAs. The system can support two types of lectures. We applied SEGODON-PDA to a lecture-type class. Students could download the contents for the lecture using a wireless LAN in class and could write something on a blackboard while carrying and seeing a PDA. They could do their homework outside of the classroom. We applied SEGODON-PDA to an exercise-type class. Students could collect ideas for the exercise of an idea generation method. They make a presentation about results of the exercise using their PDA with a wireless LAN. We have applied the system for third year students. The results of the applications are shown below. (1) The results of the application show that SEGODON-PDA is effective and highly evaluated. The class became interactive between the lecturer and students. (2) The system could support several types of lectures. The system could also support the homework or the preparation outside of the classroom.

Development and Application of a Weakly Sense of Solidarity Support System with Semi-automatic Self-declaration Function of Situations

MUNEMORI JUN, MORI NAOTO, YOSHINO TAKASHI

IPSJ journal ( Information Processing Society of Japan (IPSJ) ) 45 ( 1 ) 188 - 201 2004.01 [Refereed]

We have developed a weak-collaboration system. which shared situation information of each participant. named "hima-hima notes". Participants had forced to input the information into the system themselves manually. The load of input for the participants would be very high and then the information providing of the system would become to poor situation. We modi-fied the "hima-hima notes" and the system could provide the semi-automatic self-declaration of situation. The system forces to input participants' situation between constant periods automatically. The system decides the situation of participants based on their response time automatically. We also provide our original parameter of situations named 'himado'. The 'himado' means the ratio of the spare time. We applied the system. The results of experiments show below : The semi-automatic self-declaration function of 'himado' was effective for a weak-collaboration. The semi-automatic self-declaration became trigger to active for participants. The function must occur to increase the action, for example, the browsing other participants' situation or writing the shared white board or self-declarations of their situations.

GDA: A Combined or Shared Screen System Based on Several PDAs

NODA TAKAHIRO, YOSHINO TAKASHI, MUNEMORI JUN

Transactions of Information Processing Society of Japan ( Information Processing Society of Japan (IPSJ) ) 44 ( 10 ) 2478 - 2489 2003.10 [Refereed]

PDAs (Personal Digital Assistants) have spread widely. Radio network technology, such as wireless LAN, has also spread widely. There are many systems that support cooperative work using the latest advanced environment. However, it is difficult to do cooperative work smoothly on a PDA because the screen of a PDA is too small. Then. we have developed GDA (Group Digital Assistant). GDA can combine or share screens of PDAs. Vve experimented in cooperative work using KJ method support application that operates on GDA. We found the followings from the results of the experiments. (1) Users used combined screen of PDAs for large workspace effectively. Users used shared screen of PDAs when one of two persons mainly operated a PDA and the other advised an operating person. (2) Users changed a combined screen and a shared screen at a cooperative work frequently.

T Yoshino, T Noda, J Munemori

IEEE TRANSACTIONS ON CONSUMER ELECTRONICS ( IEEE-INST ELECTRICAL ELECTRONICS ENGINEERS INC ) 49 ( 3 ) 524 - 529 2003.08 [Refereed]

This paper proposes a new concept of a shared and combined screen for new small devices called GDA (Group Digital Assistant). In the GDA, the screens of two PDAs can be shared at a sharing view mode, and can be treated just like one screen at a combination mode. The GDA uses a wireless LAN and Bluetooth for radio communication. We have developed application software and experimented in cooperative work for evaluation. We found that functions of the GDA were effective in actual cooperative work. The concept of the GDA can make flexible usage of a cellular phone and a PDA in the next generation.1.

KAJITA KOUHEI, YOSHINO TAKASHI, MUNEMORI JUN

Transactions of Information Processing Society of Japan ( Information Processing Society of Japan (IPSJ) ) 44 ( 2 ) 317 - 327 2003.02 [Refereed]

Most of work of drawing a picture have been performed by one person. A realtime and cooperation work could be easily performed by the spread of networks. Then, we have develoved a real-time four-frame strip cartoon creation support system AB-DOKAN. AB-DOKAN is a support system for the four-frame strip cartoon creation by a few people in real time. A four-frame strip cartoon is originally drawn by one person. If comics can be drawn by many people, we can share the processes of the four-frame strip cartoon. Handwritten comics creation without computers were also performed by one person for comparatively. Consequently, we found that the four-frame strip cartoon was able to be created by a few people. The comics created by three persons take more time than by one person, but the contents tend to be interesting. Because three persons draw each frame and they think the last frame cooperatively.

YOSHINO TAKASHI, YOSHINAGA TAKAFUMI, MUNEMORI JUN （Part： Lead author )

Transactions of Information Processing Society of Japan ( Information Processing Society of Japan (IPSJ) ) 44 ( 2 ) 297 - 308 2003.02 [Refereed]

Mobile phone, PHS and PDA (Personal Digital Assistant) are highly portable, and positioning data will become important data for human communication. There are many location-aware services. However, most of services only transmit or display a partner or the position information on target as a map. There was no service using the sense of hearing or touch as expression of position information. Then, we have developed the electronic tag-playing support groupware with awareness support functions. We performed experiments 30 times with the awareness support functions and without the awareness support functions at two universities. The results of the experiments were showd below. (1) We found that the evaluation of interesting was improved by awareness support functions and additional map information. (2) It is necessary to change the method of awareness support corresponding to the size of the place of an experiment. (3) The awareness support functions are more effective by the increase in the number of times used.

YOSHINO Takashi, MUNEMORI Jun （Part： Lead author )

Transactions of Information Processing Society of Japan ( Information Processing Society of Japan (IPSJ) ) 43 ( 2 ) 555 - 565 2002.02 [Refereed]

We have developed a real-time distributed remote seminar support system, named RemoteWadaman II. The system can connect several computers via the Internet. Each student can operate his or her own computer. This system uses the following two communication methods. The first method is for large amount data and asynchronous information using a file server. The second method is for shared cursors and a shared screen using a direct communication by the mesh-type network. We developed functions to send and receive a file all over a seminar for the increase in efficiency of a seminar. RemoteWadaman II was applied seminars between two Universities 55 times and estimated by log analysis and questionnaires. Each participant was seen a shared report and shared cursors on his or her own PC, and each participant was able to use a chat. The number of sheets of a report increased by the functions to send and receive a file after a seminar start. As the result, this system has improved both the quality and quantity of a seminar.

Jun Munemori, Takashi Yoshino

Digest of Technical Papers - IEEE International Conference on Consumer Electronics 232 - 233 2002

We propose a new communication technique, which is named the brain model hyper communication mechanism for group-ware. The mechanism mimics the brain processing. The sending mechanism sends almost all kinds of data of environment. The receiving mechanism integrates and processes the data selectively and hierarchically. We developed the prototype based on the mechanism and applied it to a collaboration game. The prototype has video, voice, and the touch of sense communication channels. The results of experiment were evaluated comparatively high value when we used the touch of sense detection system.

Takahiro Noda, Takashi Yoshino, Jun Munemori

Proceedings of the IEEE International Conference on Systems, Man and Cybernetics 1 300 - 305 2002

We proposed a new concept that combines the screen of a PDA flexibly and that can flexibly choose the radio communication methods. We have developed the prototype of the system, called GDA. The screens of two or more PDAs can by treated just like one screen. That is, two or more screens of PDAs are flexibly combinable depending on the situation. As radio communication methods, GDA can choose PHS data communications and wireless LAN freely depending on the situation. We considered application to an idea generation support system. We performed the KJ method using the GDA. The KJ method with a GDA obtained relatively good evaluation from the results of the questionnaire.

Jun Munemori, Takashi Yoshino, Atsushi Yoshida

Proceedings of the IEEE International Conference on Systems, Man and Cybernetics 1 294 - 299 2002

We have developed a movable lecture support system using PDAs and wireless LAN, named SEGODON-PDA. We have applied the system lectures of third year students. The results of the application show that SEGODON-PDA (with wireless LAN) is very effective and highly evaluated, because students can download the contents for the lecture using the wireless LAN in class and can write something on the blackboard while carrying and seeing the SEGODON-PDA. The class became interactive between the lecturer and students.

MUNEMORI Jun, MIYAUCHI Emi, MUTA Tomohiro, YOSHINO Takashi, YUNOKUCHI Kazutomo

Transactions of Information Processing Society of Japan ( Information Processing Society of Japan (IPSJ) ) 42 ( 11 ) 2584 - 2594 2001.11 [Refereed]

PDA(Personal Digital Assistant)is highly portable, and the positioning data will become important data for a PDA. There are many location-aware services. But most of services using PDAs and GPSs are one-way services. So, we should develop two-way interaction services. That is, the services that clients of the system should move freely and get and present location information of other clients easily. We have developed the electronic playing tag support groupware. The system consists of a PDA, a GPS and a mobile phone. We performed five types of experiments at two universities 24 times. Four types are the electronic playing tags and the remainder is a conventional playing tag. One of the experiments can realize participation between remote universities. The results of experiments were showed below. (1) The devised services based on the electronic playing tag support groupware were better estimation than that of the conventional playing tag. The mutual positioning information using a GPS was effective for the playing tags. (2)If the accuracy of a GPS decrease, we spend a little more time to catch. But the time did not exceed the playing time of the conventional play tag. (3)We can realize the electronic playing tag between remote universities. But we should add the fealty using the remainder of five sense for lack of seriousness.
