    This paper proposes a series of evaluation method in environmental psychology using evaluator's self describing words by estimating the individual evaluation structures through the interview test applying the evaluation grid method. Because it is impossible to prepare for concrete questionnaires completely covering evaluator's views beforehand, or it is not realistic to evaluate from among a lot of choices. Applying ordinary method, it was difficult to design the completely covered questionnaire beforehand analyzing with the multivariate analysis, such as the factor analysis. The method of the proposal here consists of the next three steps. The first step, extracts the aspect of the evaluation of the evaluators by Web radaring that automates radaring which uses the evaluation grid method. Next, the layered structure of the evaluation is expressed as a network chart of the co-occurrence relations by using a hierarchical relation of the concept. At the third step, the quantitative survey is taken place by using the evaluation words obtained. And finally the layered structure is verified as a hypothesis model by graphical modeling and the structural equation modeling. This evaluation method attains minimum mental workloads evaluate by using the self describing word of the evaluator. Further this paper shows that the topological differences of evaluation structures between groups of evaluators which causes the deference of attitude among individuals. While in the previous researches formulated the individual variations by using the multi population analysis on the structural equation modeling (SEM), which means the common evaluation structure is assumed, and the individual variation causes by its waits of passes.

    Many definitions of “Kansei”have been proposed. This fact shows that “Kansei”covers very wide research regions and the suitable research systems of “Kansei”are required for each region. In this study, a framework of “Kansei”for examining the problems of practical fields as education is proposed. The proposed framework is not only focused on the results cultivated to children, but also the process of formalizing “Kansei”. In addition, using the framework of “Kansei”the examination in actual practical fields is carried out, and possibility and problem of the framework are discussed.

    The purpose of this study is to design the selection-supporting system by which everyone can easily select leather shoes suitable for events. To achieve this purpose, this research is made to find how leather shoes in the fashion match an event. Each combination of suitable leather shoes with each event is indicated as a combination of some attribute values. And then the investigation is made to find which combination is acceptable for the subjects, while using the supplemental rule. The results of the i nvestigation show that the system proposed in this paper functions to find the appropriate leather shoes corresponding to the characteristics of an event. In addition, the system based on the method of the rough sets is useful as a selection-support system.

    Evaluating Kansei from tactile feelings is useful to develop products touched by human' s hand. In this paper, we focused on the way to generate present surface shapes with asperities and proposed the method presenting surface shapes and textures of object for Kansei engineering systems and Kansei evaluations. In order to feel tactile senses of various objects, we developed a system which presents virtual tactile senses by adjusting surface shapes utilizing a haptic device. And we attempted to reproduce surface shapes and textures of virtual objects with parameters such as height of asperity, density of asperity and so on. Accordingly, the user can feel various virtual tactile senses from the reaction force of a haptic device by changing parameters in the system. We conducted a Kansei evaluation experiment to consider the difference among virtual tactile feelings and the availability of applying to the Kansei engineering. Furthermore we considered relations between virtual tactile feeling and Kansei words.

    In this study, Pictograms from a point of view of Kansei engineering and rough sets are considered. The study proposes an evaluation method of the pictogram to improve the quality of pictogram currently used. The main feature of the method is to use the Rough Set for the evaluation. As the program handles obtained from many Pictograms, the method has advantage to use Rough Sets for extraction rules that can select some appropriate data from plenty of information. Moreover, this method enable to extract the rules in the if-then assumption that can evaluate the appropriateness of pictogram already standardized and offers a new expression standard of the pictogram that has been difficult to evaluate. The result of analysis is that, the Pictograms selected from the combination table shows a good quality of information transmission method to meet with public recognition.

    Although previous studies have examined what kind of object arrangement could give observer beautiful impression, they have not achieved agreement. While some studies found observers' preference for the arrangements whose centroids were congruent with the center of the picture frame, the other studies found the observers' preference for the arrangement whose centroids were in the right side in the frame. The main purpose of this study is to solve this disagreement among previous studies. We conducted three experiments in which concreteness of the picture was manipulated, and observers rated their impression for the pictures with different centroid position. We used black circles (Experiment 1), concrete objects on white background (Experiment 2), and concrete objects on backgrounds of natural scenes (Experiment 3). Only in Experiment 3, we found that observers consistently preferred for the pictures whose centroid of the arrangement was in right side. Our results indicate that concreteness of the pictures caused the biased preferencefor the right side of the pictures.

    The present study aimed to investigate the influences of the differences in configurations of the face with no makeup on the effects of makeup in young Japanese females. Preliminary research was conducted to examine the classifications of facial configurations based on the anthropometric data of 15 parts of the heads and faces of 50 young Japanese females. The results revealed six types of facial configurations. By means of morphing software, six types of composite images were created using six non-makeup stimuli. Based on these six stimuli, two types of makeup images were created using the makeup simulation software, and these stimuli were added to the rest of the stimuli. These 18 facial images ware rated by 100 Japanese student subjects, using 14 adjective semantic scales and 13 apparent morphological scales. With regard to factor analysis, the following four factors were extracted: “femininity, ”“activity, ”“attractiveness, ”and “favorability.”The factor scores of “femininity”and “activity”had a greater influence on the effects of makeup than facial configurations. However, those of “attractiveness”and “favorability”provided the differences in facial configurations more than the effects of makeup. The interaction of facial configurations and makeup was identified in the factors of “attractiveness”and “favorability.”Although the degrees of “attractiveness”in all the facial configurations increased when makeup was added, the degrees of the increase or decrease of “favorability”as a result of adding makeup differed depending on the facial configurations. In addition, the apparent features of the eyes were affected by both makeup and facial configurations.

    This paper proposes a method for Kansei value creation to be actually reflected in consumer behavior. Looking at business from Kansei (emotional/sensitive) value creation perspective, we realize that the current situation is that in most cases value creation for products or services is not done practically. For most of the products and services put on the market, it is hard to say that their value is recognized. That is not because they lack something that reaches into the hearts of consumers but because of the poor transmission of kansei information, which leads to value creation, during the selling process. The current issues and challenges of value creation in business are shown. It provides an important aspect to show the mechanism and its elements to achieve value creation in marketing and sales activities. Some case studies are shown for demonstrating the proposed method.

    The satisfaction questionnaire survey to 130 patients who received the radiation therapy was done in this research. We used Rough-Sets to extract rules from the questionnaire survey. Various items related to the satisfaction and dissatisfaction were able to be extracted using Rough-Sets. As a result using Rough-Sets, we showed items they were satisfied were a waiting room and medical staff. When treating patients in the linac room, it was greatly related to patient's satisfaction whether radiological technologists ease patients' mental status or not. The quality and quantity of discussion with medical staff were greatly related to the satisfaction. We can say that Rough-Sets can extract the rule from the questionnaire survey with difficult extractions like patients who can't answer about questions honestly.

    In this paper, the objective assessment scale for Deep KANSEI evoked by high quality sound reproduction was investigated in the following experiments.(1) Subjective evaluation of the quality of musical sound reproduced by two different systems. One was a conventional system and the other was the Extra HI System M which could reproduce superior high quality sound by characteristics of precision wave front and planar wave.(2) Measurement of the nasal skin temperature, which is known to be an index of autonomic nervous system activity. Results showed that a greater pleasant feeling seemed to be evoked in the Extra HI System M condition compared to the condition of the conventional sound reproduction system. The long-term decrease of the nasal skin temperature, which strongly correlates to sympathetic nervous activity, showed a correlation with the subjective evaluation implying the possibility of objective assessment scale for Deep KANSEI.

    In this study, the cognition process of Müller-Lyer illusion was studied by electroencephalogram (EEG). Müller-Lyer illusion (ML illusion) is a famous geometrical illusion. In the ML illusion, the length of the shaft is overestimated when it forms wings-out (i.e., >-<) and underestimated when it forms wings-in (i.e., <->). ML illusion is frequently thought as an optical illusion because it is assumed that such an illusionary effect could be brought from its geometrical construction in terms of depth perception. However, number of behavioral studies showed that the ML illusion could be taken place not only in vision but in touch (haptic illusion). Moreover, it gives the same length miss-estimation effects to the subjects who are congenital and acquired blind. Thus, somehow, higher information processing than the optical processing in the brain is expected to be involved in the cognition of ML illusion. We investigated visual evoked potentials (VEPs) under subjects' perceiving ML illusion and non-illusionary figure (i.e., I-I) by 256chigh-resolution electroencephalography. As a result, we found a marked difference of evoked potentials between ML condition and control condition. Because such differences were more remarkable around the midline of the parietal brain where the multi-modal perception information was thought to be integrated, this result suggests that some higher information processing than the optical one in the brain might be involved in the cognition of ML illusion.

    We herein propose the usability evaluation method that is able to introduce into the process of interface design in manufacturers that often depend on qualitative method. The proposed method is characterized by the addition of the quantitative method to the conventional qualitative method. We selected the rough set theory and the interval AHP as quantitative method. It ispossible to extract cognitive advantages and disadvantages by using the method.
    In addition, we considered and verified the usefulness of the proposed method through a case study involving five digital musicplayers. As a result, samples of five digital music players were divided into two groups of high rank and low rank based on the resultsof evaluation. Furthermore, we calculated rough sets using the table of cognitive parts of the digital music players. Finally, weextracted some cognitive factors that contribute to or disturb usability of those machines.

    For the realization of the motion of a robot holding an object out to a human, which takes individual difference of affinity into account, we construct a system in which human can adjust the motion characteristics of the robot using voice instruction. Acurved path is considered as an adjustable characteristic of the motion in addition to the conventional characteristics such as velocityprofile, maximum velocity, and receiving point. The effectiveness of introducing the curved path is discussed in this research. Thecurved path is characterized by two parameters: one is the offset, which is maximum deflection from straight path, and the other is theposition of the offset. These parameters can be adjusted by the human using the voice instruction. It is clarified from the actualparameter adjustment by human subjects that the curved path is one of the important characteristics affecting human psychology, andthe desirable values of the offset and the position of the offset show individual differences.
