Collaboration mainly consists of two tasks; one is each partner's task that is performed by the individual, the other is communication with each other. Both of them are very important objectives for the collaboration support system. In this paper, a collaboration support system for 3D shape evaluation in virtual space is developed on the basis of studies in 3D shape evaluation and communication support in virtual space. The present system provides the two viewpoints for each task. One is the viewpoint of back side of user's own avatar for the smooth communication. The other is that of avatar's eye for 3D shape evaluation. Switching the viewpoints satisfies the task conditions for 3D shape evaluation and communication. In this paper, the some characteristics of the present system are described and the effectiveness of them is also demonstrated by the sensory evaluation and questionnaires analysis.

This paper proposes an intelligent diagnosis method for plant machinery in multi-fault state using wavelet analysis, genetic programming (GP), and possibility theory. The wavelet analysis is used to extract feature spectra of multi-fault state from measured vibration signal for the diagnosis. Excellent symptom parameters for distinguishing fault states are automatically generated by GP. Because the value of symptom parameter calculated to express the feature of the vibration signal fluctuates even if machine state does not change, fuzzy diagnosis is necessary. After obtaining the excellent symptom parameters by GP called GP-SPs, the membership functions of GP-SPs are needed for fuzzy diagnosis. We also discuss the identification method of membership function of symptom parameters using probability theory and possibility theory, and show the inference method for identifying faults types. The methods proposed in this paper are verified by applying them to the diagnosis of rolling bearing in multi-fault state.

In this paper, we develop a 4-DOF force display system for the analysis by synthesis of facial color for the interaction with anthropomorphic agent. By using the system, we analyze the changes in facial skin temperature and facial color associated with circulation dynamics in response to forced actions. On the basis of the analysis, we propose a synthetic method for the affect display of virtual face with facial color and expression in force display, and the effectiveness of the method is confirmed. Finally, we develop a prototype of virtual arm wrestling system with anthropomorphic agent using synthesized dynamic three-dimensional facial color and expression.

An embodied virtual face-to-face communication system is developed for three human interaction supports and the analysis by synthesis. The system provides networked virtual communication environment in which three remote talkers can share embodied interactions by observing their interaction of avatars called VirtualActors including themselves in the same virtual space. The effectiveness of the system is demonstrated by the sensory evaluation of the communication experiment and selected most favorite viewpoint when talker's own VA was semitransparently presented in 8 groups, 3 talkers per group. The importance of mutual embodied sharing in communication is also clarified. The system would be expected to form the foundation of group embodied interaction support system as well as the analysis and understanding of group embodied interaction.

A speech-driven embodied interactive actor called InterActor with both functions of speaker and listener is developed for activating human interaction and communication by generating expressive actions and motions coherently related to speech input. InterActor is the electronic media version of the physical interaction robot called InterRobot for robot-mediated communication support, which sets free from the hardware restriction. This paper demonstrates the effects of InterActor on interaction in human speech input by the analysis of speech temporal parameters. It is found that speech duration increases because of the increase of total silence duration and the number of silent parts in human-to-InterActor speech input, which is the advantage of real time processing for word-spotting and speech recognition. Interaction with InterActor is also highly evaluated in smoothness, enjoyment and preference by sensory evaluation.

In this paper we present a multimethod approach for induction of a specific class of classifiers, which can assist physicians in medical diagnosing in the case of mitral valve prolapse. Mitral valve prolapse is one of the most controversial prevalent cardiac condition and may affect up to ten percent of the population and in the worst case results in sudden death. MultiVeDec is a general framework enabling researchers to generate various intelligent tools based on machine learning. In this paper we focused on various decision tree methods, which are capable of extracting knowledge in a form closer to human perception, a feature that is very important in medical field. The experiment included classifiers with various classical single method approaches, evolutionary approaches, hybrid approaches and also our newest multimethod approach. The main concern of the latest approach is to rind a way to enable dynamic combination of methodologies to the somehow quasi unified knowledge representation. The proposed multimethod approach was capable to outperform all other tested approaches by producing classifier for diagnosing mitral valve prolapse with the highest overall and average class accuracy.

In this paper we present the results of an intelligent analysis of osteoporosis database gathered during a longitudinal study in which a random sample of 100 women who had passed precautionary examinations for detection of osteoporosis over five years and were not referred for a definite medical diagnosis was pulled from the records. The intelligent data analysis using advanced methods for decision tree construction was used in order to try to find the main factors that can reduce the risk for development of osteoporosis in women. Most of the extracted knowledge confirmed known medical criteria that put women to risk for osteoporosis, however some new interesting patterns have also been shown.
