    This paper reports on the early stages of a long-term effort to develop an efficient methodology for managing an international design workshop, using English as the medium of communication. With the aim of fostering design students who are better able to compete in the global workforce, an international design workshop was established between a Japanese and a Turkish university. Subsequently, data was gathered based on the results of student questionnaires, personal interviews, and teacher observations. The results indicate that although it required careful planning and coordination, the workshop was beneficial for students in many ways. This report also discusses ideas for how future workshops of this kind might be improved.

    The effects of a patternmaker's prior working experience with a designer on their patternmaking efficiency was investigated by comparing two patternmakers' (P1 who had considerable experience working with the designer involved and P2 who had none) work processes. P1 had a high level of understanding of the design and required less verification points by the designer. Besides, few modifications were required. Conversely, P2 asked the designer more questions and the designer requested more modifications in the toile check. It was shown that patternmaker came to be able to understand the designer's intention in the design and to predict designer's requirements by experience of working with a designer. Thus, the patternmaker was able to make a pattern that satisfied the designer's requirements more quickly and with fewer modifications. This finding increases our understanding of the effects of experience of the work of patternmakers with designers on efficient clothing design.

    The problems facing elderly who are living independently, are considered to be one of the most important motivations of the activity recognition research. The advances in sensing technologies allow collecting several types of data and communicate it wirelessly. However, most existing activity recognition systems requires pre-calculated pattern recognition models. This paper lays the theoretical foundations of a real-time methodology for activity and emotional recognition based on body and environment sensors simultaneously, then tackles one aspect of the method which is the path estimation using chest-mounted IMU sensor, for which a zero velocity update criteria is proposed. Finally path estimation results for sitting down, laying down, falling down and standing up are discussed.

    Typeface is a ubiquitous component in graphic design and multilingualism. It has increasingly become a common need in design works for people in different language systems. In this paper, we propose an affective font selection approach for exploring the juxtaposition of different languages. Japanese and English fonts are the targets. First, some evaluation experiments are conducted to gain the affective data for selected fonts. Second, these fonts are classified into several clusters proposed with similar affective propensity by hierarchical cluster analysis. Third, we analyze the relationships between type clusters and impressions by quantification theory type I. We propose to select and combine Latin and Japanese fonts in the clusters which have the closest relations with a specified impression. It is verified that the combination of Latin and Japanese type clusters could have a better effect than using original Latin letters designed with similar shape features in Japanese font packages.

    In this study, we aimed to clarify comfortable lighting locations (on both the wall and ceiling) for office work. To this end, we measured brain activity using fNIRS during arithmetic and copying tasks for various lighting locations in a simulated office space, and had participants provide subjective evaluations of these lighting conditions. There were four main results: (1) for the subjective evaluations, we observed no differences in impressions according to lighting condition. (2) The cerebral blood flow in the “wall” condition was significantly lower than that during the “ceiling” condition. (3) Changes in oxy-HB concentrations were found to differ according to condition even when task performance was the same. (4) For cognitively demanding tasks, the walls-only lighting condition seems to be the most comfortable environment. Conversely, for tasks requiring little concentration, the environment seemed most comfortable by having the lighting on the walls be brighter than that on the ceiling.

    This paper intensively examines the effects of gender and seasons on impression factors of pictures using word pairs. Previous studies have presented four impression factors for females and males: Evaluation, Potency, Sharpness, and Freshness. However, this paper finds that, for males, the factor of Sharpness could more accurately be described as Tenseness. Additionally, the factor of Freshness could be more appropriately described as Dryness for both males and females, although they have different impressions. This paper also shows that several impression factors are affected by the season rather than the temperature.

    Variety of affective states are evoked by visual art. To explore the process of feelings towards art, we studied different patterns of figures. The affection of complex pattern to feelings of goodness is still undetermined mind process. Thus, the first objective was to reveal how physical properties of complex patterns affect pattern goodness. In this investigation, we used fractal dimension and standard deviation of distance to the nearest neighbor as objective indexes related to the subjective randomness. The second objective was to determine the changes of skin conductance which reflect people's feelings when they evaluate patterns as good. We asked participants to choose the best pattern among 39 different stimuli, in the continuously changing pattern. Consequently, we proposed that the subjective randomness might be related to an affection of feeling of goodness on patterns. Additionally, we found out the tendency of increase of skin conductance value after their decision making.

    It is widely believed that there is a relationship between scent and music. For example, there is congruence among certain scent, music, and consumers' buying behaviors according to previous study. However, only limited number of scents and music have been analyzed, which is not sufficient to conclude common characteristics of congruence between scent and music in arousal dimension. Consequently, we investigated the effect of scent on the mood evaluation of music by using four kinds of scents and two music samples. Overall, our results showed the arousal quality of scent would effectively modify the perceived arousal level of music, and scent which was congruent with music on arousal could also increase the affirmation of music. These results therefore underline the potential of scent to enhance listening experience, and those working in the music industry may feel progressively further optimistic in adopting appropriate scent to achieve advanced listening experience.

    Moral Judgment is the task of judging whether the action invoked by the input sentence is good or bad from the viewpoint of the morality. In this paper, we propose a new moral judgment system using attention-based distributed representation and co-occurrence information. Compared to the previous methods, the proposed attention-based system can utilize better representation of the input sentence. In addition, the proposed system can take into account not only distributed representation but also co-occurrence information which is effective in this task. The proposed system can be divided into two parts. First one is a distributed representation learning network using attention-based Long Short-Term Memory. Second one is a moral judgment network using distributed representation and co-occurrence information. In the experiments, the proposed system significantly outperforms the other models. Furthermore, we confirmed that attention-based distributed representation and co-occurrence information contribute to the accuracy improvement.

    It is known that criminal investigation assistance systems that use face images are unreliable when profile images are queried. Although frontal facial recognition has matured, profile facial recognition is not yet well developed. To compensate for such unreliability, the use of ear recognition is a promising direction, as ear shapes are known to be unique and visible in profile images. However, the ear has a complex, three-dimensional concave shape. Thus, accurate ear identification is challenging when the angle of an ear image from a surveillance camera is different from that of images in an image database. Some studies (including our past work) have addressed this issue and improved the robustness of ear recognition against off-angle ear rotation. However, there is room for improvement in this area. To improve on our earlier work on single view-based ear biometrics, another estimation method for the camera angle of an ear image based on principal component analysis is examined in this study. Experimental results show that the proposed method can improve the accuracy of the estimation of the camera angle. In conjunction with this enhancement, the improvement in robustness against off-angle ear rotation is examined. Therefore, the proposed method improves the robustness of ear recognition by accurately calculating the camera angle of the image of the ear.

    Human senses are nonlinear to physical quantities, and a change in a minute stimulus is considered to bring a change in any sense. In the study of tone/timbre, most research considers relatively loud sounds. However, even if the physical characteristics of a tone are similar, the sensory evaluations may differ. For example, in a sound amplifier, although the differences in the physical characteristics are very small, they can be described with the adjectives, “metallic” and “soft”. Usually, specialist evaluations using adjectives are often in agreement. In this study, we examine how minute changes in sound influence a tone. Therefore, the threshold amplitude compression/expansion (ThACE) method for changing the sound in minute ways was proposed. The results of the listening test conducted in this study show the effectiveness of the proposed method. Furthermore, in case of “metallic” and “soft,” the frequency band that influences the sensitivity evaluation was found.
