The amount of money distributed in the seat category on the Rakuten market in April 2020 was a significant 280% higher than the same month last year. This shows that more and more people are using a seating chair to work on their computers in order to improve the environment for working at home. However, the 2016 study found several issues with working in a seated chair, such as poor posture and problems due to the height between the chair and the table. Therefore, the purpose of this study is to identify the factors that cause problems when using a sitting chair and the factors that make work comfortable, and to make suggestions accordingly.First, we conducted a basic experiment to identify problems when working in a sitting chair. From this result, this study proposes a cushion that makes PC work in a sitting chair more comfortable and a device that assists in standing up. The flow of the research is to pursue the functionality of the cushion itself, and then to clarify the elements of the necessary functions as a stand-up aid, and to consider adding these functions to the cushion.Experiments were conducted on existing smartphone cushions to identify factors that make working with them comfortable. Based on the experimental results and discussions, the height was set to 150mm and the size was set according to the results of the experiment. The surface is made of leather to improve stability.When we conducted a market survey on standing aids, we found that most of the ready-made products were pricey because they were for nursing care, and their appearance did not fit in with the interior design. In addition, most of them were over 300mm in height and required the user to stand up by grabbing the device with their hands, which is not familiar in daily life.In the end, we produced a final proposal that incorporated a standing aid into the cushion. Inside, a mixture of beads and cotton was placed in the gaps between the auxiliary devices to further enhance stability.The following five elements of peripheral devices that make working in a sitting chair comfortable were identified in this study.1) the height of the cushion should be 150mm, 2) the base of the cushion should be large enough to hold both arms, 3) the surface on which the PC is placed should be made of frictional material, and the surface in contact with the legs should be soft enough to fit the legs, 4) The auxiliary aid should be 300 mm in height, 5) The upper part of the auxiliary aid should be made of a material that fits the hand and makes it easy to find a place to place the hand.","PeriodicalId":164502,"journal":{"name":"Kansei Engineering","volume":"40 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129054338","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

When these psychological reactions lead to proactive behaviors such as an intention to purchase a disaster insurance policy, the psychological reactions are regarded as adaptive. According to the deficit model, information contents should strongly affect psychological reactions and proactive behaviors. However, the causal model postulates that the processing depth of information should affect psychological reactions and proactive behaviors. These models led to an examination of the deficit model in Study 1 and of the causal model in Study 2. In Study 1, 505 participants, who did not have disaster insurance at the time of the study, were randomly assigned to either the informative or less informative condition. Then, they responded to an online questionnaire which included items for demographics, risk perceptions regarding climate-change-related disasters, efficacy in dealing with climate-change-related disasters, anxiety about climate-related disasters, absence of worry about a climate-related disasters, and intention to buy disaster insurance. The results revealed no significant difference between the informative and less informative conditions, implying that the deficit model was not supported. In Study 2, 445 participants, who did not have disaster insurance at the time, were randomly assigned to shallower or deeper processing conditions, and all participants responded to the same questionnaires used in Study 1. The results indicated that risk perception and insurance purchase intentions were higher in the deeper processing condition, implying that the deficit model is partially supported. Taken together, manipulating the manner in which information is processed can be an effective way to promote proactive behavior.","PeriodicalId":164502,"journal":{"name":"Kansei Engineering","volume":"26 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116252799","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

{"title":"The Effect of the Visual Stimulus on During Rest About Online Learning","authors":"Ryusei Anzai, Wonseok Yang","doi":"10.54941/ahfe1001755","DOIUrl":"https://doi.org/10.54941/ahfe1001755","url":null,"abstract":"Online learning is spreading rapidly in the field of education with the development of ICT. Online methods are no need to spend time moving and is expected to improve learning effectiveness, but it is more tiring on the physical exhaustion and difficult to maintain concentration for a long time than in-person classes. For those reasons, it is crucial to take appropriate rest in the Physical and mental aspects and recommence learning smoothly. According to Matsui et al.'s research, the faster the visual stimulus is presented, the more humans tend to overestimate the time, which indicates that there is a correlation between visual stimulus and cognitive sense. Thus, we thought it would be possible to provide rest with a high relaxation effect by giving the learner a visual stimulus during the rest time of online learning. In this research, we investigate human’s Kansei to visual stimuli during breaks in online learning. Based on the results, the aim is to propose a resting method with a high relaxation effect. Firstly, we conducted a short-term experiment on how to display the remaining time during the rest time of online learning over a period of 4 days. The results showed that the abstract display of the remaining time was more relaxing than the concrete display. Secondly, we evaluated learners' impressions of visual stimuli during the rest time in online learning, focusing on animation. The results showed that constant, easing, steps, and coming and going animation have different impressions. We found that constant animation tended to have an impression of calmness and stability. We also found that easing animation was average in various senses and that ease-in animation was more likely to have an impression of a distraction than ease-out animation. The steps animation tended to cause psychological anxiety due to its coarseness and roughness. Furthermore, We discovered that coming and going animation was more likely to cause dynamic or flashy impressions. Based on these survey results, we proposed a resting method with a high relaxation effect. Specifically, we proposed a method to abstract the display of the break time and present the animation according to the purpose of the rest. For cooling down, it is better to use constant animation that gives a sense of calmness and stability. For raising the learners' feelings, it is better to use coming and going animation, which tends to be dynamic and stimulating. Other than that, easing animation, which has less emotional change, is considered to be effective. Thus, providing abstract visual stimuli and changing the animation depending on the type of the rest may be effective in helping learners to relax.","PeriodicalId":164502,"journal":{"name":"Kansei Engineering","volume":"81 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126225452","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Many companies have tried to create not only more powerful detergency of the products but also the new value of design in the laundry detergent bottle and package. And our lifestyle is changing like an increasing nuclear family and single life and enjoying a shopping using the internet in recent. Since selecting a detergent might be linked depending on such lifestyle, we need to survey the relationship between the design of detergents such as a bottle shape or package and the user's lifestyle. Therefore, we focused on the shape of bottles and packages of liquid laundry detergents in this study. Therefore, this study aims to clarify the difference in impressions of the bottle's shapes and packages of laundry liquid detergent based on Kansei engineering.So, we have experimented with ten bottles and packages using the ranking evaluation method to clarify the relationship between participants' decision to want to use bottles and the following items; 1) Luxury feeling level, 2) Easiness level to grip, 3) Fit feeling level to the laundry space, 4) Easiness level to store the bottle up, 5) Fleeing level of detergency power, and 6)Preference level to want to use. As a result, the item of \"Preference level to want to use\" had a stronger relationship with the bottle's packages of liquid laundry detergents than the bottle's shapes concerned with the usability of liquid laundry detergents. Even though the handle helps grip the bottles, participants preferred these bottles that do not have any handles with a luxury feel. Moreover, for the \"Preference level to want to use,\" the Kansei factors of the bottle's shape, such as \"Luxury feeling level\" and \"Fit feeling level to the laundry space,\" are more critical than the Usability factors, such as \"Easiness level to grip\" and \"Easiness level to store up.\" Also, in the bottle packages situation, the item \"Preference level to want to use\" had a more substantial relationship with the item of \"Luxury feeling level\" than \"Fleeing level of detergency power.\" This \"Preference level to want to use\" and packages differ depending on the participants' lifestyle, such as 'living style' and 'number of washes clothes per week.' For example, the participants who live alone want to use the bottle with a luxury feeling and easy to store. In contrast, the participants who live with family want to use the bottle with a luxury feeling, which fits their laundry space. These participants who live with family showed a similar tendency as the number of washes increased. Moreover, there are different characteristics in evaluating liquid laundry detergent depending on each one's lifestyle. Also, these results mean we need to survey more the condition of laundry space in Japan to propose a new bottle package design as future work.","PeriodicalId":164502,"journal":{"name":"Kansei Engineering","volume":"50 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133940590","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

{"title":"Evaluation of Elements Layout Design of Ink Painting Posters Based on Aesthetics Model","authors":"Xiangyu Ma, Chen Xue","doi":"10.54941/ahfe1001759","DOIUrl":"https://doi.org/10.54941/ahfe1001759","url":null,"abstract":"With the development of the times, perceptual design, as an important part of humanized design, has received great attention. Through experimental research, people have repeatedly verified the correlation attribute between sensibility and rationality, and confirmed that there is a strong correlation between the beauty and usability of design. Aesthetic evaluation is a calculation method that abstracts the interface elements that affect the user's aesthetic experience from the interface layout by using the theories and methods of perceptual engineering, graphics, system engineering and psychophysics. It includes 12 evaluation indexes such as balance, simplicity and symmetry. Aesthetic evaluation has become an important research direction in the fields of graphic design, product design and interface design.Ink painting is a painting made by mixing water and ink into different shades of ink. It is a form of painting and is regarded as traditional Chinese painting. Chinese painting has a long history and is a powerful carrier for the Chinese nation to inherit culture. It embodies the national consciousness and aesthetic taste of the Chinese nation. Due to its characteristics in materials, writing and artistic conception, it is unique and systematic in the field of world art.With the return of local consciousness, more and more designers choose to obtain design inspiration from their own culture. The ingenious application of ink elements in modern poster design shows the broad space for the combination of ink elements and graphic design. Ink transportation by lines is a traditional Chinese painting form. It combines with graphic design to show a unique national language and show the profound cultural connotation and spiritual heritage of the Chinese nation to the people of the world.Through the research on the attractiveness of graphic poster design with ink painting as the background, this paper abstracts the interface elements that affect the user's aesthetic experience from the interface layout, studies the main constituent elements in ink painting as modules, and obtains a unified result by means of quantitative calculation of the public's aesthetic investigation and beauty, in order to obtain the key factors affecting the attractiveness of ink painting form posters. The experimental results show that the most significant factors affecting the beauty of poster typesetting with ink painting as the background are symmetry, integrity and rhythm. In addition to the \"degree of balance\", they all correspond to the application of the law of formal beauty of ink painting. This conclusion can be applied to provide quantitative optimization basis for the typesetting form of the combination of ink elements and poster design, so as to better integrate traditional art into modern design.","PeriodicalId":164502,"journal":{"name":"Kansei Engineering","volume":"80 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134346087","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Because the music live has been canceled or postponed by the influence of the new coronavirus infection. Even now that the number of infected people is decreasing, hybrid live performances with both concert and live streaming are being held. Live streaming can reduce travel costs and time, so it has the merit of being able to watch it easily. However, it is difficult to feel a sense of unity and presence, and it does not create more excitement than concert. It has become a problem in the music industry. In order to solve this problem, we think it is necessary to pay attention to the presence or absence of audience sharing the same place and voice, which is a big difference between concert and live streaming. This study examines how to make it satisfactory live where we can feel a sense of unity and presence even if we are alone at home in a live streaming. To this end, we clarified the behavior of the audience watching concert and analyzed how to cheer.Therefore, we conducted a survey of the excitement of it based on the pyramid of Freytag.We investigated the behavior of the audience from concert videos of idols, singers and rock bands. As a result, audience’s cheering method has three types of cheering: those using voice, those using hands and those using entire body. Cheering using voice plays an important role in deciding the excitement.Live streaming has comments, social tipping, and posting on SNS as a service. However, none of them share the voice of the audience. This analysis clarified the reason why live streaming is not more exciting than concert. Thereby we considered that sharing emotions aloud between the audience create a sense of unity in live streaming. From the above, we produce a live streaming cheering system using voice. This system uses the call program to communicate with other audiences, visualize the voice of the audience and project it on the screen. It’s mechanism that increases the number of effects that express excitement as the audience’s voice gets louder. We produce it to use TouchDesigner. Moreover, subjects watched the concert video with this system. we experimented with whether the subject felt a sense of unity and presence compared to conventional live streaming. Subjects were able to shout even more by sharing voices with other audiences and visualizing their voices. In addition, conventional live streaming shared emotions by discussing their impressions with other audiences using SNS. By contrast, this system can share emotions directly through the call program, which makes it more exciting. On the other hand, subjects have an opinion that it would be better to project effects tailored to the concept of songs and concerts on the screen so that the audience would not get bored. Therefore, this system is room for the development. From this experiment, the remote cheering system using voice improve the concert experience at home.","PeriodicalId":164502,"journal":{"name":"Kansei Engineering","volume":"101 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123997400","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Ishihara","doi":"10.54941/ahfe1002988","DOIUrl":"https://doi.org/10.54941/ahfe1002988","url":null,"abstract":"Methods of Kansei engineering help the design process by surveying users’ latent Kansei, then reflecting it on product and service development and continuous elaborations of them (Nagamachi, 1991, 2012). Through our applications of Kansei engineering to product development, we have learned that there are several common difficulties. 1. Evaluation samples’ lack of variety: products in the market have limitations in design. 2. Everyone is encouraged to participate in the design process with Kansei engineering: non-designers participation greatly contributes to successful products. 3. Designers are few and too busy: designers’ efforts should be reduced and make time to think more innovatively. In this study, to ease these problems, we have applied AI image generators, a recent development of artificial intelligence, to the Kansei engineering design process.Milkcarton Kansei studies result (Ishihara et al., 1996) is the starting point of this study. First, we examine StableDiffusion (Rombach et al. 2021), an image generation artificial intelligence system. StableDiffusion (SD) seems to lack milkcarton’s shape knowledge. Then we made incremental learning of its shape with the “Hypernetworks” framework. A common method to make innovative ideas is borrowing ideas from neighboring areas. Milkcarton in red is quite a few. On the other hand, our Beer can Kansei study (Ishihara, 1998) shows that Red color has strong relation between Kansei of Premium, Gorgeous, Affected, and Showy. Then, we try to apply a red color. The AI-generated “Red flower milkcarton” is nicely designed. Our 1996 study showed that blue has the preferred color for milkcarton. Blue abstract shapes are too often used for it; then people have Kansei as “simple”, “proper” and “monotonous”. In this attempt, we seek a “modern” and “refined” touch to blue and abstract design. The AI-generated design successfully incorporated modern touch to blue-based design. Also, we have tried more novel ideas of “Colorful painting modern milkcarton”. Milkcartons have different colors and have been implicitly or explicitly intended for “Juvenile” and “Tender” Kansei. This trial also adds modern touch, and novel designs are obtained. Finally, “Jackson Pollock painting milkcarton” was examined. The result reflects his abstract painting in the 1940s, before his invention of “drop painting”.In its long-year quest for Kansei engineering, KE methodology shows its stimulating role of innovative and problem-solving design. This study challenged the use of cutting-edge AI technology to boost more innovative designs. Along with AI technology extends, further methods for boosting innovative creation interacting with humans.","PeriodicalId":164502,"journal":{"name":"Kansei Engineering","volume":"37 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132399225","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The response time of the LEDs is shorter than those of halogen bulbs and incandescent bulbs, therefore it has become easier to control lights temporally and complex lighting patterns are being used for live music shows especially in pop music. Due to the COVID-19 pandemic, internet distribution of concerts has become popular. Especially, virtual idol’s live shows (-e.g., Hatsne Miku’s live shows-) have become very popular in the two years in Japan. In the present study, audio-visual stimuli with different areas of the stage illuminated by lights and the various colors of the illumination were prepared and live pop music shows performed by a virtual idol, Miss Monochrome were synthesized using the software SHOWMAKER. In Experiment 1, the color of the lights was fixed at light blue, and the area of the lights illuminated on the stage was varied for the live music stage performed by the virtual idol. These 30 synthesized videos were used as stimuli in a perceptual experiment. Fifteen participants rated their impressions of the video stimuli using the semantic differential method. The results of factor analysis showed that the impressions were spanned by three factors, power, tension and tightness. It was also shown that the wider the area illuminated, the more powerful and tighter it come to be perceived. In Experiment 2, nine different areas of illumination on the stage were selected from the areas used in Experiment 1, and twelve colors of the lights were selected from the color wheel. Then 97 stimuli were constructed. Fifteen participants were presented the stimuli through a computer monitor and headphones, and requested to rate the impressions of each of them using 24 paired semantic differential scales. The results of the factor analysis showed that the impressions of the stimuli were illustrated by a three-dimensional space spanned by power, tension and lightness. The results also showed that the wider the area illuminated, the more powerful and tighter it come to be perceived. Moreover, a warm color of the lights was perceived as tense and a cool color was perceived as loose. A prime color was perceived as heavy and a mixed color was perceived as light.","PeriodicalId":164502,"journal":{"name":"Kansei Engineering","volume":"8 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115192502","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
