A simulation experiment was conducted to collect cases of decision making. Then, a modeling method using the decision tree was applied to the experimental results. The obtained decision tree enabled the authors to visually identify the differences in Kansei depending on the person. Finally, the authors compared and examined the differences in the number of nodes in the decision tree according to whether there was a particular attachment to the products. The results confirmed that the differences in Kansei were reflected in the differences in the structure of the decision tree. Using this Kansei decision tree method, it was possible to extract and quantitatively evaluate the factors that influence its structure. This was attained by expressing the Kansei decision-making process using the decision tree and comparing its structure.","PeriodicalId":41579,"journal":{"name":"International Journal of Affective Engineering","volume":"1 1","pages":""},"PeriodicalIF":0.3,"publicationDate":"2020-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"70687769","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}

This phenomenon is known as diffuse alpha pattern. This study aims to extract and compare the features of the connectivity between the parts of the brain. The EEGs of healthy individuals and mental disorder patients with the diffuse alpha pattern were analyzed using wavelet-crosscorrelation analysis. Five epochs of 2 seconds were analyzed for each subject. Wavelet-crosscorrelation coefficients were calculated for frequencies in the alpha band for all epochs in each subject. The results showed that the WCC values were higher in the patients with diffuse alpha. The highest wavelet power spectra in the alpha band of the patients occurred at a lower frequency. Our results suggest that the connectivity strength along the sagittal and occipital orientations in the brain of the patients could be stronger than healthy individuals.","PeriodicalId":41579,"journal":{"name":"International Journal of Affective Engineering","volume":"1 1","pages":""},"PeriodicalIF":0.3,"publicationDate":"2020-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.5057/ijae.ijae-d-18-00034","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"70683562","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}

To address this problem, we propose a context insensitive definition of security from a phenomenological perspective as well as its mathematical model through which we can understand the essence of security. Formalized syntax on security can be viewed as maintaining smooth operations even in the face of disturbances. Applying information theory to this syntax, we derive a mathematical model applicable to any situation where the term “security” appears and can understand what security is. Syntactic similarity between communication and security allows us to understand the essence of security and also to quantify security. These understandings free security from ad-hoc ways or best practices, limited to a single domain and not well-defined, depending on the Kansei, or intuition of the person in charge.","PeriodicalId":41579,"journal":{"name":"International Journal of Affective Engineering","volume":"4 1","pages":"177-187"},"PeriodicalIF":0.3,"publicationDate":"2020-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"70684031","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}

We focus on systematic study for kawaii products in terms of such physical attributes as color, shape, and material perception. In this research, we proposed a method to obtain effective attributes for kawaii cosmetic bottles. First, we collected evaluation results of the kawaii of cosmetic bottle images and constructed a model using deep learning. Then we modified the images focusing on particular attributes and evaluated them using our model to obtain effective attributes. Finally, we verified those attributes by experimentally evaluating the modified images. The novelty of this research is our new method to obtain effective attributes, which can be applied to other products and other kansei values.","PeriodicalId":41579,"journal":{"name":"International Journal of Affective Engineering","volume":"1 1","pages":""},"PeriodicalIF":0.3,"publicationDate":"2020-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.5057/ijae.ijae-d-19-00001","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"70683445","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}

And the aroma of peppermint was found to moderate the tension caused by the blocks-building task and contribute to maintaining participants’ vigor. Notwithstanding, the aromas did not have noticeable effects on people’s degrees of liking for the toy blocks and their evaluations of the product due to the sensory dominance in the multisensory product experience. The potential roles of aromas in product experience remain to be investigated.","PeriodicalId":41579,"journal":{"name":"International Journal of Affective Engineering","volume":"1 1","pages":""},"PeriodicalIF":0.3,"publicationDate":"2020-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"70683578","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 method designs two types of playlists with smooth transitions for audio track impressions: mood-boosting (uplifting) and mood-stabilizing (relaxing). Both these impressions have four patterns with different structures that alter the listener’s mood. To create a playlist, the proposed method calculates the probability of impressions for all audio tracks using a multinomial mixture model adopting a Bayesian approach and chooses audio tracks based on these probabilities. This study uses two psychometric evaluations to evaluate sample playlists for all four patterns of both playlists, i.e., whether they can positively influence a Japanese listener’s mood. The results indicate that the proposed method can achieve both these objectives concerning the audio tracks.","PeriodicalId":41579,"journal":{"name":"International Journal of Affective Engineering","volume":"1 1","pages":""},"PeriodicalIF":0.3,"publicationDate":"2020-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"70683709","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}

These inefficiencies have caused time loss and cost and interfered with market expansion. This fact strongly prompted us to study which physical features of metallic prints induce the metallic taste and then construct the index. We now suggest a metallic taste index (MTI) possessing a linear correlation with the perceived magnitude. To construct the index, we focused on the lightness distribution of the reflection as a feature of the unique metallic appearance. Figure 1 a)-b) shows a comparison of the lightness distribution property between the common colors and metallic colors. Regarding the common colors, almost all the incident light is reflected as diffuse light and the distribution becomes nearly isotropic. On the other hand, the lightness distribution of metallic colors is quite anisotropic, and the incident light is predominantly reflected around specular. This is significantly characteristic for metallic images, and a recent study demonstrated that specular, roughness and Abstract: As one of the high-value-added prints, embellished metallic prints via digital on-demand metallic foil printing have been of interest. Due to their eye-catching appearance, they are suitable for commercial prints, such as cosmetic packages and advertisements. Despite an expanding market, color management of the metallic prints still depends on visual judgment and the prescribed index of metallic taste has not yet been defined. Since the absence of an index has decreased productivity of people involved in this market, such an index based on perception has been needed. Thus, we suggest an index calculated from the lightness distribution of the real metallic images. The index possessed a linear correlation with perception and distinguished several appearances of the metallic images. It should be useful for several creative scenes in this market.","PeriodicalId":41579,"journal":{"name":"International Journal of Affective Engineering","volume":"1 1","pages":""},"PeriodicalIF":0.3,"publicationDate":"2020-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"70683993","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}
