    This paper aims to discuss the creative Kansei about life environments and urban environment concerning the process from the estimation to the proposal by means of the use of the five senses' icons by the third graders of elementary school. For this qualitative study, we have organized the fieldwork and the workshop as follows; (1) “attempt to research”, (2) “attempt to encode”, (3) “attempt to survey”, (4) “attempt to propose” and (5) “attempt to criticize”. According to the analysis, we found out the different types of estimations for the life environments and the urban environment. However, such an environmental difference does not influence in the proposals by the children. Self-centeredness and consciousness of others coexistence in the concept of the proposal for the environments.

    In recent years, along with the development of robot technology, it has become possible to move dolls and toys realistically. Robot therapy is expected to achieve similar effects to those of animal therapy. However, which element of a robot is important for robot therapy has not been examined. We surmise that humans obtain more emotional healing based on biological functions related to hugging a doll with similar size and weight to those of a human baby. This paper describes analyses of the relation between human impressions and elements of the object such as size, weight, motion, and touch. The experimentally obtained results for human impressions using dolls of five kinds, including a robot, were evaluated. The results show that motion, tender touch, sufficient size to be hugged, and weight suggestive of a human baby all gave humans good impressions.

    Rough set approach has been applied successfully to many studies of product design analysis and design support systems. Essence of the approach is regarded as acquisitions of design knowledge from a decision table, where design attributes of existing products and consumers' impressions build from their outer appearance are contained. This approach helps us design products with the target impression in a systematic way. However, impressions of products designed in the way might be generated in the same cognitive process as ones of existing products. In the sense, impressions of those products might not have any novelty. The paper proposes a systematic approach to design products that have novelty as well as the target impression. It defines a design distance in the attributes space using conceptual hierarchies of attributes values, and explores the space to find designs that satisfy both novelty and the target impression. The approach was applied to glasses design and shown to be effective for design that seeks novelty.

    In recent years, China has accomplished remarkable development. On the other hand, China has the problem that the traffic infrastructure has not caught up with economic development. In the maintenance of traffic infrastructure, it is important to perform development not only for convenience but also suitable to landscape. In this paper, especially we focused on the street landscape in the traffic infrastructure. And we investigated 32 graduate students of Southwest Jiaotong University to get the degree of satisfaction of the street landscape in Chengdu China. In the investigation, we evaluated the degree of satisfaction of the street landscape from “comfort” and “activity” these two factors by using five-stage method on 120 sheets of pictures. Moreover, the physical characteristic of these pictures was investigated. We searched for the physical factor which affects the degree of satisfaction of a street landscape by multivariate adaptive regression spline (MARS).

    Shikkai is a person who mediates between clients and artisans in order to produce printed Kimono by the best method. In the dyeing and sale system of Kimono, there are three kinds of Shikkai. There are Shikkai in mass production for manufacturers; Shikkai in custom-made system for stores and Shikkai for consumers. In this paper, in order to try to clarify origin and history of Shikkai, we investigated documents about Shikkai and interviewed several Shikkais and an artisan. As a result, we understood that Shikkai was a supervisor for artisans whose work was to dye Kimono, and how the three kinds of Shikkai came to be. In addition, we showed that Shikkai in custom-made system for consumers will be important in the future.

    The purpose of this study was to evaluate the utility of three commercially-available standing assist chairs. The control chair was a normal chair without an assist function (chair 1), while the other three chairs provided varying levels of assistance (chairs 2-4). Subjects were ten elderly individuals (age range, 65-74 years) and five younger individuals (age range, 25-40 years). We measured the extent of posture displacement when standing up from the chairs using a video motion tracking system. Elderly subjects were further asked to subjectively evaluate the chairs in a personal interview. We found that the peak hip flexion angle decreased slightly when standing up from the assist chairs compared to the control chair. The difference between angles of the hip and knee joints was smallest when using the chair that offered a medium level of assistance (chair 3). In the subjective evaluation, seven of ten elderly subjects chose chair 3 as the best chair. Furthermore, most subjects answered that the assist chairs made standing up easier compared to the control chair. These results suggest that standing assist chairs enhance body motion stability and decrease the muscular burden associated with standing up.

    Packages of over-the-counter (OTC) medicines offer various labeling information such as drug name, instructions before use, and risk-ranking information. In order to evaluate consumer attention and eye-catching effectiveness of such labeling information, an eye-movement experiment and questionnaire survey using cold remedies and vitamin supplements were conducted. For the eye-movement experiment, eye fixation duration and sequence were measured for each aspect of labeling information. After the eye-movement experiment, a self-evaluation of the consumer's attention and the eye-catching effect of each aspect of labeling information were conducted through a questionnaire survey. The results from the eye-movement experiment and questionnaire survey showed that the drug name ranked the highest for attention and eye-catching effect whereas risk-related information such as instructions before use and risk-ranking information were poorly attended. Moreover, the analysis of consumer judgment regarding the risk ranking of medicines using the normalized rank method clarified that the risk-ranking label has little influence on the consumers' risk judgment. The influence of package design on consumers' risk judgement was discussed.

    This paper aims at the scene frame generation based on the summarization of a narrative text, and studies effect of text summarization on generation of scene frame for manga drawing. Scene frames are generated from a summary using four kinds of importance degrees, the importance degree of an entire narrative text, the importance degree of a story and the importance degree of the first appearance of a character in a story, the importance degree of the sentence location. Subjects experiments are performed in order to verify the effectiveness of the present approach of scene frames generation, and study effect of text summarization. Experimental results show the present system can generate understandable scene frames of Manga from the narrative text with the summarization rate level smaller than 0.4.

    The purpose of this study is to propose a quantitative method for consumers' preference analysis using picture drawings. In this method, the picture drawings were broken down into its component elements. The component elements are analyzed by using singular value decomposition method, and the latent decision frames are estimated. The consumers' preferences are explained by the estimated decision frames using regression analysis. We demonstrated an example of this method and conducted a survey that the participants were asked to draw a picture of their feelings towards McDonalds and Mos Burger, which are considered competing hamburger restaurants in Japan. The participants in this study were 150 university students. Based on the estimated decision frames, we predicted their preference using logistic regression analysis method. The results indicate that the decision frames projected from picture drawing data explained participants' preference, and the component elements of picture drawings affecting preference were assessed quantitatively.

    To examine the effect of experience on the accuracy of travel time estimation, we compared the skilled drivers with the unskilled drivers in the estimation of time for turning across opposite traffic. In the experiment, the drivers made turn across opposite traffic at T-junction, and driving time was recorded. Estimations of driving time were also recorded before or after driving. We found that (a) the difference between driving time and the estimation of it was smaller for the skilled drivers than the unskilled drivers, (b) there was no significant difference between the estimations of driving time before and after actual driving. These results indicate that experience makes the estimation of driving time accurate.

    In this study, we focus on the sensitivity characteristic of the L-, M- and S-cones in human color vision, and construct a model that outputs two sets of Kansei values characterized as “bright - dark” and “light - heavy” using a four-layered neural network. In a subjective test, examinees evaluated 64 color patterns on a CRT display using two word pairs on a seven step rating scale. The evaluation results were standardized (min. -0.9, max. 0.9) as the output of the neural network. Three units of the input layer in the network model corresponded to the L-, M- and S-cones, respectively. The values of the absorption spectra characteristics of the L-, M- and S-cones were fed into each input unit. After training, the output of the model for both training results and performance test results were very close to the teaching Kansei values. We confirmed that the model has reproduced human Kansei values for colors. Furthermore, analyzing the synaptic weights values of the neural network model after training, we obtained the units that extracted individual differences of two color experts.

    Individual differences in impressions created by the color of cellular phones were investigated. In the study, participants were asked to evaluate the appearance of cellular phones of 16 different body colors by using the Semantic Differential (SD) method. Three-mode individual difference analysis model TUCKER 2 was used for the analysis. The results indicated that there were three types of impressions: masculine-feminine, gorgeous-staid, and evaluation. We used hierarchical cluster analysis for examining individual differences in impressions and separated the participants into three groups. Results of comparing individual evaluation structures in each group identified differences in color impression structures of cellular phones between the groups. In addition, it revealed that the color preference differences among the groups were related to some of Value-Intention Scale subscores that assess value-intending mental acts based on Spranger's classification of values.
