In the foodservice industry, it will be necessary to create new growth strategy to build up the drastic operational efficiency. A deployment of “digital recipe” concept as a method for making digital data of cooking ingredient and its process is now one of the issues. In this paper, it was shown the way to industrial futures that encourage broad use of “digital recipe” concept and Kansei information through industrial case-based study. As results, it will be pointed out to fulfill the necessary conditions as next 3 factors; 1) To evolve into the type of consolidated production management 2) To develop readily-digital controlled kitchen equipment as network-linked type 3) To set network-linked POS system to communicate between BOH and FOH by XML format. An idea of implementation level for “digital recipe” applied system was suggested as 6 step as an incremental progress. Finally, as deployment method used digital recipe concept was suggested that it will be based on an actual pilot-project merit such as mass production catering and/or production sector having complex material ordering/ staff organization. Regarding Kansei application level to create drastic management efficiency was suggested as 4 step as an incremental progress for IT applications.

A new product can increase risks of failure in this recession. Therefore it is clearly demanded more efficient and accurate marketing procedures based on scientific approach rather than human prospect relying on their experience and intuition. The purpose of this paper is to describe a practical forecasting for new product a marketing management decision system which supports the profit planning under uncertainty. In our model, we treat such the model of consumption rate that not only the rate of trial consumption for goods but also the rate of a repeat consumption. The rate of trial consumption is used consumer research data such as results from the data of concept & after using of products and advertising and retailing exposure volume. And the rate of a repeat consumption is used the variable data of change rate from the three months after product launch and degree of wish of purchase after product used test and advertising and constant. We take 18 consumer goods as an object of study. In this case, the time period under analysis is 2008. We succeeded in building the model with multiple regression analysis. Under this approach we were able to secure coefficients of determination of (0.92) and correlation coefficient of (0.96) at the twelve months after product launch which is more than equal to the past model.

This paper aims to consider the Kansei of the third graders of the elementary school to the public space through the analysis of the environmental estimation and the proposal by means of the use of the five senses′ icons. The method can be categorized into three stages, the first being the conduction of the fieldwork and workshop, organized as follows (1) “try to reserch”, (2) “try to encode”, (3) “try to survey”, (4) “try to propose” and (5) “try to criticize”, the second being the collection of the result data discriminated in quantitative terms in order to understand their tendency and the third stage being the qualitative consideration of the results.
According to the analysis during the estimation phase by the third graders of the elementary school, there exists a gap between the Hiroshima Peace Memorial Park and the Motomachi area. On the other hand, the “proposal” is more related to Kansei rather than the “estimation” where the Kansei of the children concerning the public is understood as a continuous space among both areas.

There are quite a few cases that the lack of mutual understanding and the discrepancy of communication obstruct smooth progress in projects that have a lot of stakeholders who have a different interest. The importance of Kansei communication in the project management has recognized. In a theme of project that planners cooperate with developers, this study verified the requirement that promote a project without the discrepancy of communication between them. Concretely, we did experiment to confirm effect under the hypothesis that the role of (1) the field of review and (2) the project manager is a promotion factor in good communication. As a result, we found that (1) is effective for the decrease of a product risk and (2) is effective for the decrease of a project risk. Moreover, in the process that developers materialize planner's concept, we suggested it is possible to evaluate the state of Kansei communication in project with the content of vocabularies.

In Japan, where population aging and the trend toward nuclear families are rapidly advancing, various problems attributed to changes in disease structures and life styles have become serious. Especially when someone develops difficulty in speaking and writing, there is a tendency for the person to become socially isolated because he/she does not have the ability to convey his/her intention and in some cases this might become a matter of life and death. The brain-machine/computer interface (BMI/BCI) technology is expected to allow treatment of patients with disabilities in brain or physical functions and improve the quality of life for handicapped people. One of the good examples of BMIs is the P300 speller (Farwell and Donchin, 1988). The previous P300 speller systems give the timing to the subjects with the change of brightness or colors. In this study, we suggested a new method of short-time presentation of face or word stimuli. We used those stimuli to decrease the prediction errors between adjacent choices based upon the knowledge from previous studies showing that the face and word elicited N170 component mainly in the right and left hemispheres respectively. We assumed that the difference would contribute to the decrease of adjacent errors. We compared the success rates of predictions among four conditions of visual stimuli (“brightness”, “face only”, “word only” and “face/word combination”). The better performance was obtained by “word only” and “face/word combination” than by “brightness”. These results suggest that P300-based communication will be more efficient by our methods.

Recently, in both Japan and U.S.A. the number of employees and GDP of service industries occupy 70 percent and 75 percent respectively. Service industries are now contributing most of economic growth after 2001. In this situation in order to keep and strengthen the power of our country to compete, service innovation and great improvement in efficiency and productivity are necessary in various services of private companies, administration services of government and local self-governing communities or education services of Universities. Systematic arrangement however is behind and the design of service system almost relies on human senses and experiences, hence it is not too much to say that there is no theory to design service system. The scientific approach to design service is therefore needed. Here food business is taken up and it is discussed how to evaluate consumers' Kansei on food by using dominant AHP and utilize the result of the evaluation to be able to offer various services to consumers aiming for higher productivity of service.

“Kawaii” is a Japanese word that represents a kansei value; it has positive meanings, such as cute, lovable, and small. In this article, we introduce our trials to measure kawaii feeling, a positive and dynamic feeling that occurs when “kawaii” stimulus is presented, by examining biological signals. The stimulus was presented as a screen with a colored surface in the first experiment, and as a virtual object of a certain size in the second experiment. The average heart rate obtained in these experiments indicated a significant difference between “kawaii” stimuli and “non-kawaii” stimuli, suggesting that the mental state while watching “kawaii” stimuli is more active than that while watching “non-kawaii” stimuli.

In health care science, some researchers point out that human posture is related with general physical complaint and/or any diseases. While and objective measurements to human postures as well as their classification and evaluation have been studied in this field, any reliable method has not been established. We measured human back shapes as numerical indices for human posture, and classified them by using method of functional non-hierarchical cluster analysis. Moreover, we applied silhouette statistics to find suitable number of cluster. We proposed statistical analytical process which is able to represent median back shape for each cluster graphically. We could evaluate the numerical characteristics about human back shapes using fitted curve for functional non-hierarchical cluster analysis.

Recently, neuromarketing has attracted attention, in which the customer's response to commodity and advertisement is analyzed from brain activity. In this study, electroencephalogram (EEG) was recorded while the commodity characters are presented and the familiarity towards them being evaluated. We analyzed the difference of the EEGs by the responses to the subjects (KNOWN or UNKNOWN). In the analysis of event-related potential (ERP) component P2, we found higher P2 amplitude for KNOWN than UNKNOWN. In addition, cognitive states affected induced gamma band responses (iGBR), KNOWN activated amplitudes in high gamma frequency band. From these results, we suggested that iGBR and P2 reflect cognitive states to the characters as human face familiarity.

This experiment started to find the answer to the question like ‘There might be a common stereotype image when people think of a certain object’. In the experiment three different types of character expression (Kanji, Hiragana, and Katakana) for ‘chair’ were shown to the object. The object was to sketch the first image brought up when they heard of the word. Through the experiment it was able to find how Japanese think of the object based on their use experience in past. From the result of the experiment most of the Japanese regard the shape of the chair from past memory of early learning period. On the other hand experience of using certain shape of the chair during school years have affected bringing stereotype image up of the object.

The aim of our project is to develop a design method that integrates expert knowledge with user-side kansei. In this study, as an example of a designed product, we extract design rules for the grip of a stamp. First, an experiment is conducted to obtain data for the usability and accurateness of sealing. Secondly, design rules on the grip shape of the stamp are extracted from this dataset by decision tree analysis. The results show that [1] the shape of the stamp grip affects stamping performance and leads to systematic bias, [2] especially in right-handed people, who tend make a stamp seal with a shift toward the upper right direction, along with a clockwise rotation and a blurring of the right side of the stamp mark, and [3] the key design areas of a stamp are the contact face of the thumb and the thickness of the bottom.

When operating a product, images of icons or buttons have crucial roles for understanding the use. This study focused on understanding a diverse tendency among people from different countries on image recognition. We studied two different ways of cognizing images: Attribute-oriented Thought versus Relationship-oriented Thought. Two experimental methods were tested: one was an experiment of categorizing images and the other was an experiment of image association. Through the experiment on categorizing images, it was found that there were cognitive differences among nationalities; 71 British and 81 Chinese subjects had stronger tendencies in Attribute-oriented Thought than 76 Japanese and 81 Korean subjects. Next, we examined an experiment on image association. As a result, the British and Chinese subjects had lesser tendencies in Attribute-oriented Thought than the Japanese and Korean subjects; the subjects' responses of the second experiment differed from the ones of the first experiment. These results suggested that the difference of experimental methods could influence on the way of thinking of human beings. The differences were considered as two experimental conditions: the existence of related stimuli, and the differences of cognitive processes.

We have developed a new content-finding navigation system “Roaming Navi”, in which subjective relevance between TV contents is accurately predicted by a complex non-linear formula. In order to optimize the formula, it was necessary, but difficult, to obtain enormous reliable subjective data on the relevance between TV contents. To tackle this problem, we proposed a new probabilistic method to handle subjective data, and the validity of the method was confirmed in empirical questionnaire data. Then, we conducted optimization of the prediction formula combining various optimization methods. As a result, the accuracy of the prediction was significantly improved. Moreover, these methods are broadly applicable in the discipline of Kansei engineering.

The purpose of this paper is to consider the Kansei (sensibility) of the architect concerning ‘roof’ in the journey by the text analysis from the viewpoint of Kansei-philosophy. This paper deals with Le Corbusier's journey to the east (1911). At first, we analyze Le Corbusier's descriptions extracted from Voyage d'Orient Carnets and Le Voyage d'Orient. We find that Le Corbusier describes the non-modern and physical themes for ‘roof’ (‘material’, ‘form’ and ‘color’), and the metaphysical theme concerning ‘toplight’ and ‘landscape’. We can say that the fundamental Kansei of the architect, in other words, the operation of hand on journey, takes part in the process that the non verbal tacit knowledge in the journey are written from his records, or the process that the non-modern themes obtained through the experience of journey are converted into the modern architectural theories.

The purpose of this paper is to consider the process that Kansei (sensibility) of ‘roof’ on the work of Le Corbusier (1887-1965) in the journey is converted into the modern architectural concept from the viewpoint of Kansei-philosophy. We analyze Le Corbusier's descriptions extracted from Le Corbusier's records from the journey Le Voyage d'Orient (1965), and his work collection Le Corbusier & Pierre Jeanneret Œuvres complètes, vols.8. We can extract 5 non-modern themes concerning ‘roof’ (‘material’, ‘form’,‘color’,‘toplight’ and ‘landscape’), and that Le Corbusier modernizes these 4 themes in the earlier stage of his architectural activity, and afterwards, he transforms them into the ambiguous (modern and non-modern) concept. On the other hand, Le Corbusier makes ‘landscape’ to the theory ambiguous concept in the early stage of his activity. We can say that the memory of Le Corbusier's hand in journey is not simply referred and quoted, or rather than being forgotten, the Kansei of journey is converted into the Kansei of architectural creation beyond his intention.

This paper is an attempt to describe the causality phenomenon of “Kansei Information” and its affect on buying behavior. We are focusing on information taken in through the five senses and processed within the brain, causing a positive affect, and we refer to this as “Kansei Information”. And since the year 2000, throughout Japan, in various different industries, we have been researching the phenomenon of “Kansei Information” and its affect on buying behavior. Based on our observations of this phenomenon and the marketing and sales activity it results in, we are researching possibility to make a model that relies on the affects of “Kansei Information” as the main component. In this paper we present “Kansei information/Buying behavior model”. And we examine this model by focusing on non-planning purchases in the supermarket. We will also present experiment of actual store fronts which are actually using “Kansei Information” to affect buying behavior. In this case the sales of the product, which had been around 20 pieces a month in previous years, dramatically improved and reached 280 pieces in the first month. Six months afterwards, grew constantly to reach 1,000 pieces a month. And, we examine the possibility of making the simulation model based on this outcome of an experiment.

In the positioning analysis performed during design development, the external preference analysis in which PREFMAP method is used has negative ideal points and saddle points, making it difficult to interpret the desired position of the design. This paper proposes a preference regression method that fits a preference function similar to a Gaussian probability density function to improve the effectiveness of the positioning analysis. Because this method can express individual preferences on a perceptual map of the consumer without any sense of incongruity, it can help designers easily interpret the desired design position. An experiment using the product design of digital still cameras confirmed the effectiveness of the proposed method.

In the field of marketing, questionnaires are often carried out and the acquired data are analyzed in order to design a marketing strategy. Association analysis is one of the most powerful techniques for the analysis of questionnaire data. The purpose of this analysis is to extract important rules, e.g.,{Sex=male ⇒ Evaluation of product A=3}, from the data, called association rules. It is an interesting approach to apply the association analysis to profiling in questionnaire data. However, it is difficult for the analyst to grasp the relations between rules and to find interesting rules from a large set of rules. This paper proposes a visualization method of relations between association rules with hierarchical graph structure to support the association analysis. This paper applies the proposed method to an actual questionnaire data on the impression of clothes for men's suits, and shows that the proposed method supports users to grasp relations between rules and to find interesting rules.

Companies often carry out questionnaire(s) in order to design marketing strategies or to grasp the trends. Recently, Web questionnaire survey becomes popular with the spread of the Internet in order for companies to reduce cost and to get a lot of questionnaire data. However, in the Web questionnaire survey, some respondents do not answer the questions seriously, because it is not done face-to-face and is done just for giveaway basically. The authors have tried to quantify the conflict of response based on the contradiction by the pair(s) of questions with counter meaning. One of the most important matters in the quantification of the conflict of response is the selection of the pair(s) of opposing questions, which are actually regarded as opposite meanings by respondents. This paper defines the distance between questions which shows the similarity of questions for respondents and proposes a method to derive pair(s) of opposing questions based on the distance between questions. This paper applies the proposed method to an actual questionnaire data and shows more appropriate opposing questions for respondents can be extracted than the prepared pairs of opposing questions.

This paper evaluates the impression of questions and answers at Q & A sites in order to avoid the problem of mismatch between the questioner and the respondent. First, 50 impression words effective in evaluating impressive expression of statements are selected from a dictionary in order to measure the affinity of the question to the response so that we could match them properly. We then conduct an impressive evaluation experiment for 60 question and answer statements posted at Yahoo! Chiebukuro by using those impression words. Nine factors are obtained by applying the factor analysis to the scores obtained through the experiment. Lastly, the best answers, which are decided by questioners, are tried to be estimated by using the factor scores.

Human kansei is one of the important factors in recent product development. Thus, management of knowledge about consumers' feelings is an essential task in current industrial design. For the purpose of such the knowledge management, development of a descriptive method to identify feelings is needed. In this paper, we measured implicit attitudes to color combinations using affect misattribution procedure, and we analyzed proportions of positive responses to each stimulus. The results showed that chroma contrast was explained by a concept of perceptual fluency. According to the finding, we discuss significance of the perceptual fluency which links physical features and impressions from the viewpoint of ontological description. The discussion indicated a need for development of a descriptive method for correspondence between physical features and impressions explained by perceptual fluency (e.g. symmetry, contrast, prototypicality).

We develop the ethno-cognitive interview which is the interview method to grasp the business reality, and it was tried whether it was applicable in visualization in a gap and an analysis of consciousness of customer satisfaction. We interviewed per 1 person for 1.5 hours to customer which thought law customer satisfaction to us and to our SE, business worker. As a result, a CS gap was classified into 3 of territory. (1) There is a clear difference in the value of the customer and us, and you point the sweetness of our recognition out to a customer, (2) The customer and we recognize dissatisfied, but the recognition isn't being handed down to a customer, (3) There are no differences in recognition, but both are unsatisfactory. We found out that there is a root in a CS gap in difference between mutual organization and recognition of a system.

It is necessary to understand design subjects correctly to develop products with attractiveness and problem solving for users. It is not easy to lead to a big improvement even if the problem on HCI of the product is individually solved. Additionally, the solutions will conflict together. It is necessary to grasp the problem as not individual but group. And also it is necessary to discover wide subject scope. The present study pays attention to the relativity of problems and situations in which the problems are caused. Situation key words are extracted from the problem situation. Next, the relations between situation key words are clarified by Hayashi's quantification method-3 and cluster analysis. And, the result of case experiment is described. In discusses, the content relates the fact concerning the number of situation key word and the number of the product which is surveyed.

Nonverbal communications involving physical contact convey “Kansei” information that is difficult to express in verbal communications. In this study, we proposed a method to investigate “Kansei” information in nonverbal communications, and surveyed how people perceive nonverbal communication involving physical contact. In the psychological experiment using questionnaire, we presented various words describing tapping and patting actions with Japanese onomatopoeias and sound symbolic words expressing a concept or nuance that is difficult to verbalize explicitly. Participants first imaged the situation wherein they made communication with another person through the physical contact, and then evaluated the “Kansei” information of communications and rated them by adjectives. We found that onomatopoeias added a variety of impressions to communications with physical contact. We then applied factor analysis using adjective rating to extract a factor space of the communicative actions. For both tapping and patting motion, the first factor represented atmosphere of the behavior, and the second dimension represented activeness of the physical motions themselves. We then mapped the rating scores of desirability of the communication onto the factor spaces. The scores of the first and the second factors well predict in an additive way the desirability of communication for both actions, and the influence of the first factor was stronger than that of the second factor. These results suggest that the structure of factor space represents desirability of the communication regardless of actions. The proposed method may be useful and efficient to investigate the Kansei information, factor space, and their inter-relation, of nonverbal communications.

Recently portable digital music player and music player application become popular. With these items, we can store and play thousands of songs. But it is very difficult to choice the music that suits his preference and the situation by the time. In this research we propose the new User Interface to selecting the favorable music. With this User Interface, user can know the next music. And if user judged that he don't want play it, he can change it with other music from the several choices. Based on this approach, user can avoid from playing the unfavorable music, and can easily select the favorable one. As the result of evaluation, it was confirmed that our User Interface has intensified the user's satisfaction.

This study focused on the estimation of cognitive information for unnaturalness that human feel. Estimation of unnaturalness from the human brain activity is one of key technologies for quality evaluation. Previous studies demonstrated that the amplitude of the oddball P3 component depend on the naturalness of visual stimuli. However the method requires multiple measurements for estimating clear ERP signal. This study, therefore, aims to estimate cognitive states about naturalness from single-trial EEG signal of the visual oddball task. This study adopted individual component analysis as pre-processing method, principal component analysis as feature extraction method, and, support vector machines, as classification method. This study estimated human cognitive state about unnaturalness from single-trial EEG.

There are many reports of medical errors mainly caused by the similarity of drug names in Japanese such as ‘_??__??__??__??__??_’ (Amaryl) and ‘_??__??__??__??__??_’ (Almarl). In order to prevent such errors, one of the authors studied methods of measuring the similarity of drug names and implemented a search engine to find pairs of similar medicine names. However, the existing methods only evaluate sequences of common substrings. In addition, although some methods took the similarity of character (letter) shapes into consideration, they assumed that the similarity of each character pair is given, usually by hand. In order to define the objective similarity index of medicine names, it is also necessary to measure the similarity of character shape objectively. In this study, we propose a method to evaluate character similarity by image processing and apply the method to the medicine name similarity that we propose.

A set of movement feature values, called a Laban's feature value set, is proposed here in order to explain observers' impression of bodily expression. The design concept of the Laban's feature value set is based on Laban Movement Analysis (LMA), which is a proven theory in body movement psychology. In this paper, we adopt a Human Form Robot (HFR) as an agent of bodily expression because this is the type of a robot better adapted to Human-Agent Interaction (HAI). Relations between Laban's feature values and HFR's emotions (Happy, Angry, Sad and Relaxation) which are the subjects of this study were examined using the analysis of correlations. By the consideration of Russell's circumplex model of affect, we discussed the correlation in terms of each axial (“pleasure-displeasure” and “degree of arousal”) characteristics. Next, principal component analysis was conducted to examine multi-dimensional correlations. Finally four estimated emotion equations are generated by using the Laban's features.
