Implementation and Performance Evaluation of WWW Conference System for Supporting Remote Mental Health Care Education.

Recently in Japan, the mental health care has become a very important issue because there are many people suffering from mental problems. Also, there are only few specialists and researchers to deal with these problems. The information technology (IT) has changed our life. People can communicate between them and students can study various courses at anywhere and anytime using the Internet. The IT can be helpful for mental health care, education, aftercare and counseling for patients and their families. It is very important to decrease the moving time because there are very few mental healthcare specialists. Also, it is very important to see the facial expression and speak to the people for mental healthcare education, aftercare and counseling. For this reason, the video and voice are needed. But, it is not easy to use the conventional TV conference systems for general people, mental health care specialists and their students because they are not computer specialists. In order to realize a remote mental health care education, we have developed a WWW conference system. Our system can communicate between the mental health care specialists and their students. Also, our system can provide the communication between the mental health care specialists, patients and their families by using the live video on WWW browser, point to point communication, point to multi point communication and multi point to multi point communication. In this paper, we show the implementation of proposed system.

Relation between Kansei words and the room space in digital traditional Japanese crafting system

In Japan, there are traditional Japanese craftings such as fittings, furniture, textiles, etc., which are closely related to Japanese culture and life. The design of Japanese houses and their rooms is a very important problem to attract people. However, this design is not easy because people have different feelings. In order to deal with this problem, we have developed a Digital Traditional Japanese Crafting System (DTJCS) which provides a presentation space for traditional Japanese crafting. In this paper, we analyze the effect of room change of fittings to peoples feelings using the presentation system.

Kansei retrieval method using VPIC of traditional Japanese crafting objects

We propose Kansei retrieval method using the quantitative feature of traditional Japanese crafting object to provide a user with the desired presentation space in digital traditional Japanese crafting system. First, we extracted visual quantitative feature values by using visual pattern image coding (VPIC). Those values include the total number, the frequency, the dispersion rate and the deviation rate of variety for edge. Next, those quantitative feature values for traditional Japanese crafting objects are registered in the multimedia database. On the other hand, the relation between Kansei words and the visual feature of traditional Japanese crafting objects are analyzed by using the questionnaire. Last, the visual feature is related with the quantitative feature values. Through the above process, Kansei retrieval method can be realized. We describe the possibility of realization for Kansei retrieval method using the quantitative feature of 3D object.

Traditional Japanese crafting presentation system based on VR and Kansei information processing techniques

Technical evolution of traditional crafting industries by multimedia and network technologies performs very important role to survive in modern industrialization in the world. In this paper we propose a three-dimensional CG presentation system using Kansei information processing and Virtual Reality technologies. A large number of data concerned with traditional Japanese fittings are stored in the database distributed over Internet. User can easily retrieve the desired fittings according to his/her Kansei and design not only the traditional Japanese interior but also combine those with western interior to build creative and original houses, hotels and other buildings. We built a prototype system in which user can also walk through the designed virtual space as a Japanese room organized by Japanese traditional fitting in. Taturu-Hama-Cho and interactively change those fittings by the selected ones based on his Kansei from the distributed databases over Internet. As a result, we could verified the usefulness of our suggested system not only for Japanese crafting presentation fields but also for worldwide design industries.

EVALUATION OF KANSEI RETRIEVAL METHOD FOR QUANTITATIVE FEATURE EXTRACTION

In this paper, we propose a Kansei retrieval method based on the design pattern of traditional Japanese crafting object to provide a user with the desired presentation space in digital traditional Japanese crafting system. The visual quantitative feature values are extracted by using Visual Pattern Image Coding (VPIC). These values include the total number, the frequency, the dispersion rate and the deviation rate for different edges. The quantitative feature values for traditional Japanese crafting objects are registered in the multimedia database and the relation between Kansei words and the visual feature of traditional Japanese crafting objects are analyzed by using the questionnaire. Then, the visual features are compared with the quantitative feature values. Through the above process, we can find the relation between the design pattern components and edge types using VPIC. By finding this relation, the Kansei retrieval method can be realized.

Method of sharing virtual traditional crafting system based on high-speed network

In this paper, it proposes the method of sharing space that enables collaborative work in the virtual traditional crafting system based on high-speed network (JGN2). We are building the presentation system which deals with human sensitivity in virtual reality environment. So far we have proposed three different presentation systems of an Internet version and a SGI version. In this research, when the business model is considered, we think that collaboration support in sharing space is required of remote users. Therefore, JGN2 which is a next-generation high speed network was used to interconnect remote CAVE systems, and realize of the system which can perform interactive operations in sharing space is aimed.
