Emotional state before sleep affects the subsequent sleep onset. The purpose of this study was to investigate how positive/negative emotion before sleep effected hypnagogic state. The movies eliciting positive or negative emotion were presented before sleep. Hypnagogic imagery was recorded as a probe of emotional experience and EEG microstate analysis was used for finding the emotion related EEG activities. The score of emotion ratings for hypnagogic imagery indicated that positive emotion was reported in not only positive condition but also in negative condition. This implied that hypnagogic state might be accompanied by positive emotion. Comparing the appearance of maps obtained from microstate analysis between conditions, the map of right temporal activity was significantly greater in positive condition while the map of the left frontal activity was greater negative condition. These results suggested that the emotion not just in presleep but also in hypnagogic state was involved in sleep onset process.

This paper describes linguistic features of generally unreadable person names, which are defined as “KIRAKIRA names,” and proposes a method to detect KIRAKIRA names based on the features. Through the discussions, the following eight features are founded as the linguistic features of KIRAKIRA names: 1) Too many Kanji characters, 2) Too many syllables, 3) Multiple usage of a common Kanji character, 4) Kanji variants are used, 5) The pronunciation of Kanji is generally unknown, 6) Too many stroke count for Kanji, 7) Mismatching of gender between a person and the name, and 8) The pronunciation of name equals an imported word. Based on the features, KIRAKIRA names are automatically detected by using Support Vector Machine. The experiments to detect KIRAKIRA names were conducted for 10,000 names. The results of the experiments showed 81.79% accuracy, 76.89% precision, and 91.84% recall.

“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.

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.

We examined how changes in participants' heart rate affect their estimation of time when listening to music. We manipulated participants' heart rate using a cycling task on an exercise bike and by varying the tempo of music. The heart rates of 48 participants were measured before and after the pedaling task on the exercise bike. One week later, they listened to the music and estimated the temporal duration (60 seconds) under the non-manipulated condition (without exercise) and heart rate manipulated condition (with exercise). The results showed that the duration of the music (60 seconds) was underestimated after light exercise and overestimated after strenuous exercise. These results suggest that the acceleration of the internal time mechanism due to an increase in the heart rate affects the perceived duration of time with relation to music.

In this paper, we propose an automatic generation system of the comic from a newspaper article. In the proposed system, two characters appear in the generated comic: one has a role of questioner and the other is elucidator. These characters are created using an automatic comics generation tool named “Komipo!”. First, the proposed system analyzes the text of a newspaper article and every sentence is presumed the importance and importance analysis and emotion analysis using language resources are carried out for each sentence. From the result of importance and emotion analysis, the system chooses the characters having suitable expression and a pose to the sentence of an article. The system converts the text of an article into spoken language from the literary language. If there is a difficult word in a text, the proposed system generates additional frame to explain the meaning of the difficult word. The background image for every frame is chosen from Flickr. In the image selection process, not only language processing, but also the result of image analyses is used. Evaluation experiments have been carried out and we confirmed that the system is able to choose the image suitable for the text of an article by performing image processing. In addition, it has shown that the expression by a comic style contributes to readability and easiness of understanding for newspaper articles.

Kawaii is one of the representative concepts of Japan-original Kansei. In this paper, we categorized Kawaii motion of Roomba and investigated the correlation between physical properties of motions and Kawaii-ness. First, we classified motions of Roomba into 10 types. Impressions of those motions were investigated and three of them were found to be Kawaii by subjects. Based on the findings, we formed a hypothesis that variations in acceleration, namely the jerk, affect Kawaii-ness. Second, we evaluated parameters of seven physical properties (position, velocity, acceleration, angle, angular velocity, angular acceleration, and time) of three Kawaii motions of Roomba. Then, we created 24 types of robot motions and evaluated impressions of them. The physical features of created motions were correlated with the Kawaii-ness of them. The result indicated that the jerk certainly affects the Kawaii-ness of motion but not always. It clearly indicated that the Kawaii-ness of motion is multifaceted.

This paper is aimed at evaluating the effect of prolonged mental stress on human physiological state. The human secretory immune and endocrine substances were introduced as “biomarkers” of such a prolonged stress. This relatively new field of study investigating the relationship and/or interaction between human mental and somatic states has been developed according to the development of the molecular analysis techniques, such as Enzyme-linked immunosorbent assay (ELISA), and showed that the several secretory hormones and immune substances could possibly be useful stress markers. However, what types of stressors and its duration could be evaluated by such biomarkers is not well understood. In this article, the effect of prolonged mental stress during long-term graduation examination of undergraduate students was investigated comparing with the effect of short-term mental stress by simple arithmetic task. As a result, one immune substance within saliva, immunoglobulin A, was showed as a possible stress marker for both long- and short-term stressors.

In this paper, we propose an automatic manzai-dialogue creating system. Manzai is performed mainly by a pair of two comedians. One (called boke) says strange things in a funny way and the other (called tsukkomi) corrects them. This is how they can make their audience laugh. In the proposed system, first, a sentence in a text is changed to a sentence having strange meaning. Then the proposed system produces a sentence which points out the mistakes and sometimes corrects it in a funny way. Tsukkomi does not only correct the mistakes but also compares them to something (called tatoe tsukkomi). By repeating this kind of processing, the proposed system can change a text to a manzai script. MeCab, Japanese language morphological analyzer and Japanese Google N-grams are employed to choose the candidate words considering word similarity and phonological similarity. We conducted experiments to evaluate the proposed system and confirmed the effectiveness of the proposed automatic manzai-dialogue creating system.

In product development, a method of cost cutting is required for manufacturing prototypes. Based on our recent research, we propose a low-cost prototyping system for subjective evaluation using a virtual environment. We call this method “Virtual prototyping using Kansei evaluation”. We determine the surface roughness and orientation, surface reflectance and transmission of surface-finished papers. Measured data are analyzed using directional statistics and subjective evaluation of surface-finished papers. As a result, we obtain the surface roughness and orientation, as well as the directional intensity of the surface-finished papers. We described the Kansei structures of subjective evaluation “thin”, “weighty”, “airy”, “hard”, and “tender” from kurtosis and luminance of surface reflections and transmissions. Using these techniques, it is possible to create surface appearances for virtual prototyping.

Kimono is a traditional Japanese garment. Several types of dyeing artifices have evolved through the process of printing traditional patterns on cloth in Japan. Paper stencils can be considered merely tools used at an intermediary stage of the dyeing process. And yet another problem is that most stencil cutting craftsmen are getting older, and thus the traditional art of paper stencil cutting may be lost under present circumstances.In this study, we explored the possibility of replacing paper stencils produced by traditional techniques with those produced by a laser cutter. And we compared actually dyed textiles by using existing and new techniques, in an attempt to achieve a quality of paper stencils produced by a different method that is closer to the superb quality of traditional artifices. As a result, we were able to suggest the guidelines on materials and patterns suitable for producing the stencils with a laser cutter.

We produced the average face by combining forty-one facial images of female college students in order to investigate how the facial impression changes depending on distance between eyes and eyebrows. Furthermore, we produced ten experiment samples by shortening or widening distance between them of the average face in five steps respectively. These images were presented individually to ninety college students, and they were asked to evaluate them using twenty adjective pairs. Consequently, the average face received high evaluations about likability-related impressions, while the faces with shorter distance between eyes and eyebrow got high evaluations about activity-related impressions. Moreover, two principal component (“degree of refinement” and “femininity”) were extracted as a result of principal component analysis to evaluation scores. It was found that degree of refinement was likely to be affected by the perceived size of the eyes, and femininity was defined by distance between eyes and eyebrow.

This study analyzes the factors for detecting agents to implement a human-like agent in werewolf games, which are new themes in game studies of artificial intelligence. A comparative experiment was conducted to reveal the influences regarding the degree of disclosure of the agent existence; seven players and an agent participated in four games. Communication logs were collected from the game logs. Impressions for each player was reported in questionnaires with five-point scales and detection of the agent were reported in a free writing. Although the most players, who did not know that an agent played the games, did not be aware of the true character of the agent, the most players who knew the existence could detect the agent. The statements of detected agents differed from them of other players. This study concludes that the technical requirement for agents is to adapt to statements of other players.

This study investigated the basis of a right-side dominance in aesthetic arrangement. In experiment 1, in order to examine the effect of attended position in pictures on aesthetic arrangement, we manipulated the positions of the fixation points, which attract observer's attention, and centroids of triangle arrangement for three objects. Participants rated preference, balance, beauty and harmony by the use of seven points scale for each of the pictures. We found that participants evaluated highly aesthetic in viewing the pictures whose arrangement centroids were near to the fixated position. In experiment 2, in order to examine the effect of participant's dominant hand on aesthetic arrangement we presented the objects which the participants are willing to manually manipulate, or the object which they should avoid to manually touch for right-handed or left-handed participants. We found that right-handed participants evaluated highly aesthetic in viewing the pictures whose arrangement centroid was at right side, but left-handed participant did not.

Humans have various impressions for visual stimulus such as order/disorder and aesthetic preference, but the brain characteristics that each impression reflects are not readily apparent. We hypothesized that perception of order/disorder reflects the stimulus processing fluency. We conducted one preliminary experiment and two main experiments. The preliminary experiment simultaneously presented two stimuli to participants, who judged which stimulus was the more disordered. We scored perception of order/disorder using participants' responses. The main experiments used a same-different judgment task to assess the hypothesis. We presented two stimuli simultaneously, scored with perception of order/disorder. Participants reported whether the stimuli were the same or not. Participants easily judged whether the two stimuli were the same or not when the same-difference task included the stimulus perceived as orderly. Results suggest that the impression of order/disorder reflects the processing fluency for each stimulus.

This paper proposes a method to detect attractive phrases from musical lyrics. The method considers not only acoustic but also lyrical features which attract human attention. Through the interview on impression for lyrics, we have found that “uniqueness of co-occurred terms” and “repetition” significantly influence human attraction. Therefore, we modeled these linguistic expressions as mathematical features. The proposed method detected attractive phrases using support vector machine with the modeled features. The results of the model evaluation experiments showed the 69% accuracy and 86% precision. Moreover, the results were compared and discussed with the key sentences detected by the existing summarization methods. As the result of comparison, it is confirmed that the proposed method detected attractive phrases more accurate than the existing summarization methods.

Short-pause is one of the important elements of presentation. In this study, we have investigated differences of taking short-pauses between winners and losers of book review presentation game, Bibliobattle. In order to find short-pauses, non-utterance sections in presentations are detected by converting time discrete audio signal to energy. Length, times and appearance position of short-pauses of winners and losers were compared. As a result, the following things were revealed. The first is that the average times of winners' brief (less than 0.4 sec) short-pauses is significantly smaller than losers' one. The second is that the losers' average times of short-pauses which appeared in unnatural position (between noun and postpositional particle or suffix) is significantly larger than winners' one.

Onomatopoeia refers to words that represent the sound, appearance, or voice of things, which makes it possible to create expressions that bring a scene to life in a subtle fashion. In this paper, we propose an onomatopoeia thesaurus map to enable the construction of a map that visually confirms “similarity relationships between a number of onomatopoetic words” and “similarity relationships between unknown onomatopoetic words and existing onomatopoetic words,” which are difficult to grasp from a conventional thesaurus. It is also possible to label objects with onomatopoetic words and visualize the similarity relationships between the objects on a map. In this paper, we introduce an example of labeling onomatopoetic words relating to the textures of sweets (desserts).
