    We build a method for new feature descriptions of 3D models. This method is based on independent or combined descriptors with shape and specular reflection to retrieve 3D models with light. Light plays an important role in form and appearance of 3D objects. We obtain a good relationship between shape and specular reflection and high-grade of 3D chair models. We compare independent descriptors and combined descriptors for shape and specular reflection by multiple regression analysis. As a result, we find that form and the position of specular reflection play an important role in high-grade response to 3D chair models using two kinds of light.

    This study investigates lighting conditions for elderly people under which object is perceived as “kirei”, according to implications of clarity and preference. An experiment was conducted using Semantic Differential method with young and elderly subjects to assess the appearance of objects under white LEDs, incandescent lamps, and fluorescent lamps. Results suggest that lighting under which objects are perceived as “kirei” for elderly people is that from incandescent lamps. Additional study is necessary to determine whether this result was obtained from the correlated color temperature or lamp-specific characteristics. Furthermore, assessment structural analysis was conducted using Graphical Modeling per age groups. These models suggest age-related differences of the assessment structure under which objects are perceived as “kirei”, especially the relation between “kirei” and brightness.

    Effective online search for apparel products was investigated, and three systems were proposed, constructed and evaluated. The first system developed (Projection System) can project and display apparel products along a plane of two attributes chosen from a master list attributes relevant to apparel products. A second system (SOM System) was developed to resolve the problems found in “Projection System”. “SOM System” was created, based on a Self-Organized Map (SOM). In the last system (Improved SOM System), the arrangement of products in “SOM System” could be customized for each user and provided a better user experience with more effective results. Search experiments were conducted for these systems. The number apparel products displayed in “Projection System”, was much higher than that of a conventional search system, due to duplicate displays. While the display of “SOM System” seemed to be more effective, the arrangement of products was difficult to understand. In “Improved SOM System”, the issue of the arrangement of the products was resolved. With each new system, it was possible to find the desired product from a larger product offering, while also improving the quality of the search experience.

    For the purpose of providing information for the apparel field, the effects of changing the pleat number and skirt length on the visual image of 30 types of pleated skirts by age group were analyzed. The major results are as follows. Changes in the pleat number and skirt length were strongly related to the visual image of pleated skirts; the more pleats there are, the more complicated, dressy and feminine they look, while the fewer pleats there are, the more calm and plain they are regarded. In addition, it was revealed that the shorter the skirts are, the more casual, childlike and simple they look, while the longer they are, the more formal, heavy, mature and luxurious they appeared. Image changes were much more significant for the skirt length than they were for the number of pleats, while for age groups, the number of pleats accounted for much larger differences in visual image than the skirt length. In particular, compared to other age groups, there was a significant difference in image scores for subjects aged 10 to 19 for skirts that were uncommon, and for subjects in their 50s for skirts that gave them a sophisticated and charming image. As a result of principal component analysis, it is considered that the 1st principal component analysis (PC1) largely contributes to an element expressing sensitive fashion image based on expression, while PC2 contributes to the age factor based on activity. However, it was revealed that the items which strongly influence the major components are different by age, as are the items which determine the image of pleated skirts.

    This is a feasibility study that uses various visual images of products to investigate an abstract concept known as tiresomeness. Tiresomeness can be an important criterion when consumers make up their minds to purchase new products. This study aims to grasp the characteristics of tiresomeness and how consumers generally recognize its existence, as well as to clarify the conditions that evoke tiresomeness. Based on a discrimination experiment, visual elements associated with product designs are extracted to study the conditions that influence whether a consumer gets tired of observing visual images of 12 products. Tiresomeness is produced as “function”, “design”, “experience”, “time” and “interest”. It is clarified that the design elements that controll tiresomeness are “simplicity”, “statement”, “the number of colors”, and “usability”.

    In this study, we focused on the rarely utilized temperature sense, and examined the sensory characteristics of temperature in order to develop an interface device that utilizes the distribution of temperature in the palm. First, we evaluated the sensory characteristics of temperature in a part of the palm. Moreover, we investigated the relationship between the distance of two-point temperature stimuli and the identification characteristics based on the sensory characteristics of temperature in a part of the palm. For this experiment, we obtained the knowledge regarding the relationship between temperature and sense of temperature. Moreover, the results suggest that the discrimination rate improves when the distance between the two-point temperature stimuli is more than 20mm. From this study, we were able to ascertain the knowledge required for developing an interface that utilizes the distribution of temperature in the palm.

    This study compared psychological and physiological indices while listening to different music compositions to examine whether music compositions that differ in their psychological index also differ in their physiological index. In this study, the physiological index was the brain activity measured by near-infrared spectroscopy (NIRS). First, the psychological indices of six music compositions were determined, from which two music compositions that resulted in opposite affective values were identified. The activity of the brain was measured by NIRS while the subjects listened to these two compositions. A trend was found that the two compositions with different psychological indices were also different in the physiological index, suggesting that the difference in psychological index may be reflected in the brain activity in and around the prefrontal cortex.

    This paper compares impressions between music and images aiming at construction of an automatic music-and-image-combination determination system by taking the personal preference into consideration. Since the combinations may depend on personal attributes such as his/her age, taste, etc., the preference to these music and images may change person by person. In order to solve this problem, psychological tests are conducted to clarify the relationships between the impressions of music and images, and a study for similar-impression combination grouped by favorite genre is explored. As a result of these experiments, we confirm that similar-impression combination depends on user's preference with regard to their favorite genre of music.

    The purpose of this study is to create a Kutani-ware positioning map, to find the optimal positions for new products and sales promotions by preference regression analysis and to find out effective design elements to use in conducting positioning analysis instead of Kansei evaluation data by consumers. As a result of conducting positioning analysis using Kansei evaluation data, Kutani-wares have been placed on a two-dimensional surface with Dimension 1 “Heavy - Light” and Dimension 2 “Dynamic - Calm.” Also, as a result of preference regression analysis, it has turned out that Kutani-ware popular with consumers are of non-traditional designs. As a result of conducting positioning analysis using design elements, we have found out design elements to obtain positioning map similar to positioning analysis using Kansei evaluation data. Such a method as used in this study can be anticipated as a low-cost positioning analysis. The results of this study are susceptible to the influence of elements that act as axes and the originality of designs, however, and a generalization of the results requires further research.

    An experiment was conducted to capture characteristics of human-agent interactions in a collaborative environment. The goal was to explore the following three issues: (1) Whether the user's emotional state is more stimulated when the user has a human schema, as opposed to a computer agent schema; (2) Whether the user's emotional state is more stimulated when the user interacts with a human-like interface, as opposed to a non human-like interface; and (3) Whether the user's cognitive state is more stimulated when the user interacts with a familiar representation, as opposed to an unfamiliar representation. Results obtained in the experiment suggest that: (a) Participants with a human schema produce higher ratings, compared to those with a computer agent schema, on the emotional (interpersonal stress and affiliation emotion) scale of communication; (b) A human-like interface is associated with higher ratings, compared to the cases of a non-representational interface, on the emotional (interpersonal stress and affiliation emotion) scale of communication; (c) A familiar interface is associated with higher ratings, compared to the cases of an unfamiliar interface, on the cognitive (information propagation) scale of communication.

    There have been a number of cultural anthropologic studies of masks. However, it is still considered difficult to make a principal component analysis of masks that represent human and animal faces due to the emotional factors they possess. This paper discusses one such principal component analysis of participant impressions of certain masks. Masks employed in this study share the property of being used to disguise oneself as something else. Participant impressions of masks were investigated as reference to a semantic differential method. Additionally, this data was analyzed using a basis analytical method. Thus, I hope to gain knowledge regarding the effects of sensitive amplitude where outward appearance may have an influence on audience experience.

    Recently, the number of studies concerning the development of an interface device using the tactile sense has increased. In this study, we focused on apparent movement occurring in response to temperature stimuli. Apparent movement has been widely studied; however, knowledge regarding apparent movement occurring in response to temperature stimuli is limited. Moreover, the relationship between the rate of occurrence of apparent movement and the factors associated with the occurrence of this movement remains incompletely understood. Therefore, we performed an experiment to evaluate the effect of 2 factors (stimulus duration and stimulus onset asynchrony) on the rate of occurrence of apparent movement. In this experiment, 10 healthy men were asked to place their hand on Peltier elements and answer whether apparent movement occurred. The results of our study show the presence of appropriate conditions for the 2 factors that increase the occurrence rate of apparent movement. Moreover, a strong correlation was found between the rate of occurrence of the apparent movement and clarity of the movement.

    The relationship between expressions of a class teacher on the class atmosphere was investigated. First, the frequency a teacher showing six basic expressions was assessed. Secondly, the atmosphere of the class was evaluated and factors that composed class atmosphere were subjected to factor analysis, which indicated that class atmosphere consisted of Unity, Friendly, and strict Factors. A model how expressions of a teacher affected the atmosphere of a class was developed using Covariance Structures Analysis (CSA). The results indicated that the expressions of a teacher had a significant effect on class atmosphere.

    An emotion tagging method using emotion-related words is proposed and applied to access log analysis of news site in this paper. We regard emotion as the feeling which ordinary people have from the viewpoint of a third party. The system tags one of 8 emotions (joy, like, safe, fear, anger, disgust, sad, shame) to one sentence. There are 5 steps in the proposed emotion tagging method. 1) The system tags emotion to the sentence directly which have the emotion-related word in emotion database. 2) The system does morphological analysis for the sentence which can't be tagged emotion in the first step. 3) Searching emotion queries based on emotion-related words are made using emotion database. 4) The system posts the searching emotion queries and each word in the sentence to Mainichi news database and calculates the co-occurrence score. 5) The system changes the score considering the importance of each word. The emotion which has the best co-occurrence score is tagged to the sentence. The experiment result shows that the rate of correctness of the proposed emotion tagging method is about 80%. For emotion based access log analysis, we gathered the access logs of Asahi web news site. The system tags emotion using proposed method to each gathered news headlines. After emotion tagging, the system extracts the emotion based rules from the access logs by counting the frequencies of emotion sequences. As a result of access log analysis we obtained some interesting rules such that users tend to read news which convey positive emotion successively.

    Humans are aware of their world due to sensory input and a variety of information from all five senses is integrated into the brain. Research on the mechanisms underlying sensory integration has been extensive; however, few studies have investigated information arising from three or more sensory inputs. The purpose of the present research is to clarify the importance of sensory integration of information arising from the visual, auditory, and tactile senses. Three experiments were conducted to determine the integration of visual images, sounds, and vibrations from a haptic mouse, to investigate the matching of a combination of multi-sensory information represented by digital information. A greater impact was seen for visual information than for auditory or tactile information when the three types of information were presented simultaneously. A difference was also noted for presentation time for visual, auditory, and tactile information.
