おしぼりの温度が感性評価に与える影響について
添田泰弘, 北本拓磨, 長谷川光司

Oshibori is a small wet towel to wipe hands before meal in Japan. Most of researches on oshibori have investigated the towels from the perspective of cleaning and sanitation. Few studies have assessed the qualitative and sensory characteristics associated with oshibori. In this paper, subjective evaluation experiments were carried out using cotton oshibori of different temperatures such as 5, 15, 30, 45, 60, and 75 °C in the laboratory temperature at 20, 25 and 30 °C over four seasons. 29 males and 33 females evaluated oshibori on following properties such as “favorite,” “rare,” “hot,” “feel-smooth,” “high-grade,” “comfortable,” “soft,” and “moist,” according to five point grading. As results, the oshibori at the temperature of 5, 15, 45 and 60 °C were evaluated to be comfortable. Contrary, those of 30 and 75 °C were evaluated uncomfortable. Moreover, sexual specificity of the evaluation was observed.

腹部への被服圧が心身に与える影響とその閉眼・開眼における比較
上前真弓, 上前知洋, 上條正義

The purpose of this study is to investigate the effect of clothing pressure on physiological and psychological responses, to create an evaluating method of the clothing comfort. We have investigated the physiological and psychological responses to the clothing pressure in both situations which eyes open and eyes closed. The pressure amounting to 90% of the subjects' waist size was applied to their abdominal region by the waist belt. The influence of clothing pressure on physiological and psychological responses were evaluated by the following measurements: sensory test, electrocardiogram, electroencephalogram and blood pressure. Consequently, when subjects were fastened by waist belt, sympathetic nerve activity increased in case of eyes closed. On the other hand, parasympathetic nerve activity increased in case of eyes open. The physiological and psychological responses are different in eyes closed and eyes open conditions. The results mean that the clothing comfort on the pressure requires a sensory multimodality evaluation.

香りの分類における心理学的検討
若田忠之, 齋藤美穂

Classification of fragrances has not accepted widely, because the range of stimuli was very wide and words of evaluation were a little. This study picked up essential oils, and selected words from prior questionnaire. Purpose of this study was to classify fragrances by psychological method. This study consisted of 2 experiments, A and B. The same materials and procedures were used in both experiments. Subjects were asked to evaluate fragrances by SD(semantic differential) method. In experiment A, a total of 220 subjects were joined and 15 pair words were used. In experiment B, 75 subjects were joined and 18 pair words were used. Cluster analysis and Factor analysis were used for analyzing the data. As a result, in both experiments, 11 clusters and 3 factors were observed, and clusters of citrus fragrances were showed. The factor of “Pleasantness” was showed in the first factor. This factor was common both experiments.

CGで作成された人物の印象形成に外見特徴と背景が及ぼす効果
松田憲, 楠見孝, 瀬島吉裕

We investigated the effects of pre-preferences for CG characters (avatar), gender of CG characters, exposure frequency, and the concordance between CG characters and the background on the impression formed about CG characters. During 8 sessions, 36 participants were shown a succession of CG characters presented against concordant or discordant backgrounds. During sessions 1, 3, 5, and 7, participants evaluated each CG character in terms of post-preference, intelligence, and reliability using a 7-point scale. Session 8 involved a delay condition. The results showed that post-preference evaluation scores in the high pre-preference condition were associated with better first impressions of CG characters, and increased with exposure frequency. However, background conformity influenced the impressions of CG characters when pre-preferences were medium or low. In addition, post-preference and reliability evaluation scores were higher for female than male characters.

Twitterを用いたニュース記事における読み手の感情推定手法の提案とアクセス解析への応用
本間幸徳, 萩原将文

In this paper, we propose an estimation of reader's emotion towards news articles using Twitter, and apply this method to the access log analysis of a news website. The proposed estimation method is divided into 3 steps: 1) The system collects tweets about news articles from Twitter. 2) The system tags each tweet with an emotion. 3) The system estimates the reader's emotion towards the news articles using tweets obtained in the second step. The system can tag an article with one or more of 11 emotions (anger, dislike, excitement, fear, like, joy, relief, sadness, shame, surprise, nothing). The experimental result shows the effectiveness of this method using Twitter for estimating the reader's emotion. For access log analysis based on emotion, we collected the access log of a self-produced news website. The system tags each collected news article with emotions using the proposed method. We analyzed the access log by using Hidden Markov model (HMM). As the result of access log analysis, we obtained some interesting findings such as that the users tend to read the article which causes excitement or surprise at the start.

インタラクションの同期タイミングにおける感性的要素を利用したインタラクティブな大規模配信システムの設計
山田博之, 久積英朗, 手林大輔, 久保田大輔

Streaming views of stable video images are now available to any household thanks to today's widespread Internet use and faster speeds. Seminars that combine moving images with documents are now proliferating, particularly in markets that target user education. The POWERLIVE GigaCast online seminar system was developed based on an overall system design that focuses primarily on user interaction. With a balance of stable basic functions and optimized interactive functions, the system supports large-scale communications at a significantly reduced cost. Throughout the development of GigaCast, we have identified the following 3 elements in regards to the user interaction: 1) information which should be synchronized with user actions; 2) information which provides the illusion of being synchronized as long as kept within a certain timing in order; and 3) information which does not require to be synchronized. Especially, for the above 2) and 3), we have discovered that it is possible to free up some space in design by dispersing the load required to the server system through providing explicit control while taking advantage of their characteristics.

看護師に対する緩和ケアのアンケート調査データのルール・アンサンブル法による分析
下川敏雄, 布内美智子, 松本晴美, 辻光宏

The importance of team medical treatment in which doctors and co-medical colleagues (i.e., nurse, pharmacist, CRC, and so on) treat cancer together has been increasing. The nurse's main roles are to help with the cancer therapy and provide mental support to patients and families. We surveyed the concerned nurse's involvement in the cancer therapy using a questionnaire. We asked them the need for palliative care, importance of team medical treatment, etc. The purpose of our analysis was to explore factors that influence the nurse while providing palliative care. Multiple linear regression analysis is one of the most popular methods for performing data analysis of questionnaires. However, it cannot construct a model with an interaction effect and nonlinear structure. We adopted the rule ensemble (RE) method because it can model nonlinear and interaction structures. Furthermore, in the RE method, the estimated model can be interpreted based on rules (base learner). Moreover, we illustrated some graphical representation evaluation of estimated RE model. Therefore, we provided some influence factors about the intention of the nurse during palliative care and illustrated them using a graphical representation.

地域ブランドにおけるブランド想起の測定手法の開発
林靖人, 阿部隆夫

In this study, we have examined the objective phenomenon and mechanism of Place “Brand Recall” by a DRM paradigm which mainly used in psychological study of False Memory. In experiment, the participants have learned about local resources name lists which do not contain the local place name and some major resources. And after some questionnaire task, they have answered recognition test which consist of list presented words, non-presented place relation words and non-presented non-relation words. As a result, in spite of not having been displayed in learning phase, participants have reported the existence of non-presented Place name and other local resources as False Memory, but non-relation words not reported. The result of experiment shows that occurence of False Memory means the strong convergent associations of local resources with place name.

ラバン理論に基づいたヒューマンフォームロボット身体動作の動作特徴抽出と表出感情推定
増田恵, 加藤昇平, 伊藤英則

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.

デザイン開発におけるポジショニング分析の活用
池本浩幸, 山岡俊樹

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.

物語のシーンの印象に基づいた声楽曲の生成
石塚賢吉, 鬼沢武久, 加藤茂

This paper describes a system which composes operetta songs fitting to story scenes represented by texts and/or pictures. Inputs to the system are original theme music, numerical information on given story scenes and story texts. The system composes variations on theme music and lyrics according to image of music and lyrics obtained from numerical information on given story scenes. Evolutionary computation is applied to generations of variations and lyrics. Using a vocal synthesizer and a general midi synthesizer, the system plays operetta songs as the variations on theme music with the lyrics. The system reflects user's Kansei to variations on theme music and lyrics using interactive evolutionary computation. This paper also describes the evaluation experiments to confirm whether the composed songs reflect impressions of story scenes appropriately or not.

飽きを感じる感性のモデル化に関する研究
稲村博央, 野間裕子, 荻野晃大, 庄司裕子

There are many existing studies on information recommendation technology for presenting information better suited for the user's preference; however, no existing studies took account of human nature of being tired of the same old thing. This study has proposed a Kansei model that can be conscious of the boredom that arises from similar things repeated. Specifically, the model takes menu planning as a problem domain and formulates a sense of being tired of the same old thing. In addition, the study applied this Kansei model to actual data of menu planning and simulated a transition of the monotonousness level. Finally, it carried out an experiment with subjects to make a subjective evaluation for the same actual data, compared with a simulation result obtained using the model, and discussed the validity of the model created in this study.

ル・コルビュジエの東方への旅における「壁」への感性
千代章一郎, 萩野亮

The purpose of this paper is to consider the Kansei (sensibility) of the architect of ‘Wall’ 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 of ‘Wall’ (‘Material’, ‘Opening’, ‘Color’ and ‘Ornament’), and the non-physical theme concerning ‘Light’. From his records, we can say that the Kansei of the architect, his non-verbal, tacit knowledge, is fundamental to his experiences during this journey. These non-modern themes obtained through the experience of journey are converted into the modern architectural theories.

嚥下性に優れた錠剤形状の研究
佐藤英明, 齊藤静男, 林豊彦

Drugs and supplements come in various forms, such as tablets, granules, hard capsules, soft capsules, jellies, and syrups. We examined how the shape of round tablets affects ease of swallowing, since tablets come in various shapes, sizes, and colors. Round tablets are characterized by their diameter, radius of curvature, and thickness. There have been no studies of the relationships between these factors and ease of swallowing, and no method is available for sensory evaluation of ease of swallowing. We therefore constructed a “Map of tablets shape for swallowing” using the RSM-S (Response Surface Method by Spline) to examine the relationships between three factors (diameter, radius of curvature, and thickness) and ease of swallowing. Our “Map of tablet shape for swallowing” was found to be effective in the initial phase of tablet design.

感性・主観を用いた地理認知促進のための地図モデル提案
平林里葉子, 田野俊一, 市野順子, 松村一男

Current map systems fail to provide the information that a walker really needs. Because the information that the walker wants is always changing. Current map systems are inadequate because of giving only one index in indication of a map. The conventional map expression technique have used only one kind of indexes such as a sight substance, a hearing substance, or a sensitivity substance. In contrast, an aim of our study is map expression of the forms that system compound, and each layer supplements them each other. Our map is made by investigating at first which kind of map should be used for the promotion of the human geographical recognition. Therefore this paper investigated the number of the landmark in their recognition and the difference between persons who could read a map well and who could not. We carried out three experiments. The first experiment is designed to find out the differences in the concrete landmark between persons who understood a map and who cannot read a map. The second experiment was based on the result of the first experiment and clarified of the important element except the visual object in the human cognitive map. The third additional experiment was performed with the result of the second experiment to examine how map system show multimedia elements. The technique of four kinds of map expression designs was implied from the result of three experiments. And the Layerd-map model is proposed as a presentation method to display them adequately.
