JOURNAL FREE ACCESSAlthough it is generally said that the makeup color that best fits facial skin should be of the same type of color, professional makeup artists sometimes use the opponent color to emphasize the beauty of skin color. The present study demonstrated how the colors of eye shadow changed perception of redness or yellowness in the face. Three face colors, neutral, reddish, and yellowish, and 7 typical colors of eye shadow covering all hues were examined. The brightness of the faces was fairly high. Sixteen female students compared the color of faces and ellipses to evaluate their redness and yellowness. Serial and simultaneous presentation of the face and ellipse were implemented. The results showed that only some reddish eye shadows, like red, pink, or purple, enhanced the redness of reddish as well as yellowish faces in the serial presentation of face and ellipses. Examination of the chromaticness index of the colors that had a significant effect of color induction revealed that the colors with high positive values of a* and medium positive values of b* showed an assimilation effect in complexion.View full abstractDownload PDF (1372K) -

JOURNAL FREE ACCESSMany past studies have shown the effects of music listening in many domains. This study aims to investigate the effects of listening to music related to design project on designer's idea generation. The within-subject design was adopted in the experiment. The subject carried out lamp design under listening to music related and unrelated to design project. After the experiment, they performed retrospective reports. The results indicated that listening to music related to the design project can create an atmosphere with the design theme and provide hints to the hearing resources, helping designers guide the direction of idea development. Moreover, while listening to music related to the design project, the majority of subjects can generate more ideas associated with the design theme as well as the episodic memories. Consequently, they tend to express their ideas by the things relevant to design project they usually contact. However, in the situation where music not related to the design project is playing, subjects generate fewer ideas related to the style of design project and they tend to develop their ideas based upon the design elements required for lamp design.View full abstractDownload PDF (1456K) -

JOURNAL FREE ACCESSThis paper makes a case study of Moka Pot through four stages. The first stage is data collecting, which uses KJ method to select 20 samples. The second stage is data analysis, which adopts factor and cluster analysis of product samples and research words to generalize five representative Green Kansei modeling words: "natura", "leisurely", "harmonious", "reliable" and "easy-to-use". The third stage uses morphological analysis to classify test samples into five items and four levels. A total of 1024 forms are generated and then Taguchi method is utilized to generate 16 test samples L'16 (45). The fourth stage is analysis and verification. As per S/N ratio (signal to noise ratio), this stage uses Taguchi method to find out optimal modeling scheme of each Kansei word. This study introduces green conceptions, adopts Taguchi quality design method, integrates innovative design approaches of Green Kansei products, as well as uses Taguchi method to investigate Green Kansei words and main points of Kansei modeling factors.View full abstractDownload PDF (1686K) -

JOURNAL FREE ACCESSDue to the diverse user requirements of products, it has been important to develop the products to satisfy them. Human design technology (HDT) constructs a structured concept of a product and clarifies and evaluates the product functions required by users. However, this design method is mainly applied in the early design process and is not so effective in the late one. This paper proposes an improved HDT using Quality function deployment (QFD) that enables the designers to extract the design elements considered in both early and late processes and to analyze the relationships between them. The proposed HDT enables the designers to consider the engineering characteristics of design objects and to comprehend the relationships of the whole design elements regarding the product development in order to proceed to the late process of design. Additionally, a design example is presented to demonstrate the proposed HDT and to indicate the method seems to be effective not only in proceeding to the late process of design but also in generating new product concept.View full abstractDownload PDF (1257K) -

JOURNAL FREE ACCESSInteraction Design has different definitions in different areas. Generally, it is the creation of physical and emotional dialogues between a person and a product, system, or service that can be experienced during the action and reaction between form, function, and new technology. User-product interaction describes the behavioral relationships between user and product, which are analyzed to understand the tangible actions and apply that knowledge to product design applications, including the design of the symbols that help the user understand the product's intended use. In any kind of interaction, affordances (characteristics of a product that help users perform tasks) play an important role. Proper evaluation of the role of affordances in these interactions can result in better-designed objects and consequently better user-product interactions. Current methods of evaluation in the user-product interaction design process have not been fully explored, and new, more scientific approaches are needed. In this study we focused on a statistic evaluation model of the behavioral relationship between user and product. By studying theoretically reviewed, multi-disciplinary papers and projects dealing with affordance and related fields, we summarized and systematically explained how to evaluate user-product interactions by analyzing the affordances, which are generally focused on cognitive, physical and functional information. This paper proposes a new analytics-based, user-product interaction evaluation (UPIE) model which can provide product designers with more informative and reliable interaction data, and ultimately help them redesign and improve user-product interaction.View full abstractDownload PDF (983K) -

JOURNAL FREE ACCESSThis paper investigates how a new approach to evaluating user-product interaction can benefit the product designer's interpretations of evaluation results. It describes an experiment that studied users' interactions with a high-end coffee maker, through the lenses of human science and user-product evaluation by using a combination of affordance theory and Structural Equation Modeling. The concept of our proposed User-Product Interaction Evaluation (UPIE) model is derived from identification of relationships between human experience, affordance, knowledge and context-of-use, and consequently reveals the relationships that influence designers' and researchers' concepts of evaluation in product interactions. These relationships and concepts were used to form a hypothesis that certain evaluation principles of statistics can inform the evaluation model of a design, especially with regard to the aspects of affordance that trigger people's understanding of a product's use. In this paper, we describe how the User-Product Interaction Evaluation model was created, and how it can aid designers in the design process.View full abstractDownload PDF (1189K) -

JOURNAL FREE ACCESSUser experience, known as the users' cognition responses to the look and feel of a product, has been evolved and recognized as one of the prominent aspects in product design and development. Theoretically, the studies of user experience have been expanding, adapting from psychological research to design research. user experience, a concept which places users as a central focus, has been used for creating products that are provide aesthetically pleasing and pleasurable to use as it focuses beyond usability and traditional design strategies. However, since the concept of user experience is still broad and arguably unclear in definition, there are a few numbers of practical researches of user experience that stress the benefit of this emphasizes in different directions, such as creation of product differentiation by user experience, brand building and longevity of a product. This study provides an understanding of user experience concept and its relationship with product design by product specific example and how roles of user experience are generated. In addition, framework and model to explain the stages of user experience in product interaction is proposed. This study identifies three main roles and contributions of user experience in product design: user experience as product differentiator, decoding of complex technology and product longevity. Finally, a framework to explain the mechanism of user experience stages during an interaction with a product is proposed. This research expects to elicit the design researchers to further explore and investigate this topic in order to compels and expand the benefit of user experience in another direction. Particular design research effort is needed for developing tools and methods applicable in design practice that would enable designers to create differentiations of their products based on user experience approach.View full abstractDownload PDF (1237K) -

JOURNAL FREE ACCESSThe use of shading and texture can add details to an image and provide an overall surface quality. When designers attempt to enhance viewers' impressions of graphics, it is based on an understanding of their emotions. Indeed, facial expressions are considered effective tools for understanding human emotional reactions. We conducted an emotion recognition experiment based on facial expressions to understand the emotional responses to two sets of sample images: (1) without, and (2) with shading and texture. FaceReader, an automatic facial expression recognition software program, was used to measure participants' emotions, and the sample images were categorized by a focus group using the Kawakita Jiro method. The emotion data were imported into SPSS, and a t-test was performed. The results revealed some differences in the participants' emotional responses for neutral, happiness, anger, and disgust. Emotional differences between two sets of the sample images and the feasibility of applying facial expression recognition to understand emotions were confirmed; i.e., physiological signals reflect feelings and correspond to people's verbal representations. This study can guide designers in establishing emotional connections with viewers by using design elements to reflect consumer interests.View full abstractDownload PDF (1526K) -

JOURNAL FREE ACCESSThe construction of Taipei City Walls was started in the Qing dynasty (1882 A.D.) by Guangdong craftsmen. It was the last city that used the concept of feng shui during the Qing dynasty and the only rectangular stone city in Taiwan's history. Taipei is the most modernized city in Taiwan, and the construction of tall buildings and skyscrapers has led to the gradual disappearance of the original Taipei City Walls. Taipei City Walls is unique in the history of Taiwan, and its design and planning are also different. This study used text analysis and case investigation to consider space according to the process of changes in the social history in an attempt to analyze the design aesthetics of Taipei City Walls as the preliminary foundation for urban design aesthetics in Taiwan. The analysis of the design aesthetics according to several aesthetic principles showed that the principles of the presentation of style beauty included: Host-Guest disposition method, Graphic harmony rule, Significant harmony rule and Landscape viewing rule, breaking through the past politics-based power distribution. Although the aesthetic principle has been called an historical inheritance, its meaning was completely different, and it initiated the city morphology of Taipei City.View full abstractDownload PDF (1451K) -

JOURNAL FREE ACCESSIn product design, sketching while designing serves various roles, but the effects of individual sketching skills, such as perspective expression, structure, and shape development, have yet to be clarified. Herein a structural model of sketching skills is proposed to unify and classify sketching skills, and the role of sketching in the thinking process of design is analyzed using the Multispace Design Model as a comprehensive viewpoint based on the effects of various sketching skills previously elucidated. The results show that in the thinking process of design, sketching is used to generate ideas for the optimum design by a top-down process, which optimizes the results in physical space using the analysis results in psychological space. Additionally, sketching is used to evaluate ideas for the emergent design by a bottom-up process, which extract new meanings in psychological space based on attribute development in physical space.View full abstractDownload PDF (1421K) -

JOURNAL FREE ACCESSThere are more and more ceramicists with distinctive ideas designing enormous masterpieces of ceramic teapots recently in Taiwan. Among them, many design forms have not only broken through the traditional limitations, but also enriched the tea ceremony culture of Taiwan. Drinking hot tea with unique teapot has been recognized as fashion image of Taiwan. However, what features or characters are really recognized as Taiwan is essentially important from the cultural aspect of point. This study focused on the investigation of design style and cultural identities of Taiwan teapots. It employs the methods of focus group and KJ method from four professional ceramicists who have won grand prizes to generate the constructs of Taiwanese design style on teapot. Samples of contemporary teapots are exclusively collected and analyzed. As a result, the reviewers have been identified some fundamental principles for the design of Taiwan teapot. Further, tentative models for the design of ceramic teapot with Taiwan identity are also proposed for the cultural identity study and future development of contemporary Taiwan teapots.View full abstractDownload PDF (1867K)
