In this paper, we implemented a speech emotion recognition system that can distinguish human emotional states from recorded speech captured by a single microphone and classify them into four categories: neutrality, happiness, sadness and anger. In general, a speech recorded with a microphone contains background noises due to the speaker environment and the microphone characteristic, which can result in serious system performance degradation. In order to minimize the effect of these noises and to improve the system performance, a MA(Moving Average) filter with a relatively simple structure and low computational complexity was adopted. Then a SFS(Sequential Forward Selection) feature optimization method was implemented to further improve and stabilize the system performance. For speech emotion classification, a SVM pattern classifier is used. The experimental results indicate the emotional classification performance around 65% in the computer simulation and 62% on the ARM platform.

최근 제품에 있어서 가치는 기능성을 제공하는 측면에서 점차 사용성과 감성을 중요시하는 방향으로 변화하고 있다. 최근의 혁신적인 제품을 보면 사용성과 감성적인 가치가 기술개발의 방향성까지 결정하는 등 제품개발에 있어서 감성과 사용성 가치의 중요성은 더 더욱 커지고 있다. 또한 감성과, 사용성에 대한 정확한 예측은 제품의 개발 방향뿐만 아니라, R&D의 방향성을 결정짓기 때문에 이와 같은 Value를 표현할 수 있는 정확하고 신뢰성 있는 모델의 중요성 갈수록 높아지고 있다. 하지만 제품개발에 있어서 감성과 사용성으로 대변되는 User Experience 가치 제공은 기능성, 신뢰성 등의 기존가치와는 달리 소비자, 사용자로 대변되는 Human에 대한 더 높은 이해가 필수적이나, 관련 지식의 부족 및 통계적 정량화, 객관화 어려움 등으로 제품의 가치로 연결시키기에는 많은 어려움이 있는게 사실이다. 본 논문에서는 감성과 사용성 등을 고려한 제품 가치 체계(Product Value Structure)에 대해서 살펴보고, 아울러 이러한 가치를 고려한 제품개발 패러다임의 변화에 대해서 살펴보고자 한다. 또한 기존의 감성 사용성에 대한 방법론에 널리 활용되는 통계적 귀납적 방법론 외에 인지과학(Coginition Technology)을 활용하여 연역적 방법론에 대해서도 고민해보고자 한다. 특히 Iphone의 UI 특성을 통해 Innovation Company가 인지과학적인 Approach를 어떻게 제품개발에 적용하고 있는지에 대해서 알아보고자 한다.

With the shift of consumer’s spending behaviors further into emotionally-driven purchases, the role of brand is becoming even more important, which in turn, expands design’s role in the brand image strategy. The contact point between the consumers and the brand is the primary channel for building strong brand image through experience. Therefore, it is critical to comprehensively plan and manage the consumer contact point for any brand. Given the changing market conditions, the objective of this study is to define and structure an integrated design development and management system for building successful brand image. In order to do so, the research analyzed the characters of brand image, the conditions for consumer experience and the roles of emotion. The analysis into the correlation between images and emotion process model yields three natures of an image. The image 1) is based on empirical decisions, 2) expresses and conveys emotional aspects and 3) builds mental values through a sense of sympathy. Through case studies of successful designs that meet all three characteristics, the roles of a brand icon in building strong brand image and the needs for integrated design approach for implementation are defined. The methods for integrated design include 1) providing a focal point through brand image positioning, 2) utilizing visual themes based on brand image plot, 3) building a Total Identity Program to holistically manage brand images and 4) developing brand icons for brand image reinforcement.

Dynamics of Sijo was regarded as a genre of 'closed nature' once. But ironically thanks to the 'closed nature', today dynamics of Sijo is refocused in diverse fields. Sijo is quoted not only in its original field of literature, but also in writing study. Quite remarkably, it is often referred to in the field of literary therapy, further in emotional healing. This article discussed the dynamics of Sijo as a manifestation of emotion especially called Gamsung in the process of the refocus. It is to show effectively that as a literary genre, Sijo can interact and share what is reasonal as well as what is emotional and sentimental in a poem as an emotional container beyond the lyricism Sijo has. Of course, it is also clear that the concept of lyricism may limit the dynamics of Sijo itself. Thus, the key word 'Gamsung' mainly referred to in this article was used to show the dynamics which Sijo has as much as possible, overcoming the limitation. That is, the purpose of the study is to prove that Sijo is the genre to represent human emotion most dynamically by reviewing the reasonal aspect of Sijo in addition to its emotional disposition which has been estimated to focus on sentiment or emotion. In the process of reinterpreting the structure of Sijo, the specific analysis on such emotional disposition and reasonal aspect was conducted by structurizing that as '(1) Facing, (2) Feeling dynamical, (3) Interpellating by feeling, and (4) feeling by sensation'.

With its history of two thousand years of studying the human mind, Confucianism may be applied to contemporary emotional science for its unique perspectives and methodologies in understanding the origin of the human mind. By examining the Confucian understanding of human mind according to general Confucian ideas as well as the scholar, LEE Whang's, an idea similar to contemporary 'emotion' in Confucianism was discovered. Importance of the sentiment was not in the resulting goodness originating from one's fundamental nature, but rather its goodness was only achieved when human nature manifested itself without any distortion. This good emotion, namely 'sensibility', presents the essential difference Confucian understanding bears in comparison to the contemporary concept. And the system for grasping the human mind was considered to be the viewpoint of examining the contents and subject of function than a formal system of functioning human mind. It assumes the stance of looking into thehuman mind from the general and synthetic view of contemporary cognitive, emotional, biological and philosophical perspectives. Overall, the researchconcludes that there existed a long history of high-level research into the human mind in Confucianism that may satisfactorily provide partial reference and understanding as well as consequent perspectives and knowledge for discovering the common denominator with the emotional science.

As the Production technology Progresses, the necessity to consider consumers needs being complex and diverse in the phase of developing product is being more important. However, existing system of consumers needs being structured with the view of marketing is too abstractive and categorical to apply in the phase of developing product. So, the goal of this study is to establish method that structuralize customer's needs for applying practically in the phase of the product concept development and to suggest guidelines to needs structuralization with emphasis on the view of cognitive science/cognitive psychology. The major findings of this study is summerized as follows. First, to structuralize not only customer's needs category which being used as standard to assort needs in existing way but also practical needs features, it must contain the concept of emotion that is actual product's meaning to customers in its structure, and for this reason, the structuralized needs with emotions can be defined as emotional needs structure. Second, categorization of concept will be divided as essential concept and referential concept centering around symbolic concept, and from this supposition, emotional needs structure can be composed as benefit concept(essential concept), customer needs(referential concept) centering around emotion(symbolic concept).

Since the domestic introduction of iPhone in 2009, use of smartphones rapidly increased and many tasks, previously performed by various devices, are now performed by smartphones. In this process the importance of reading little text using small smartphone screen has become highly significant. This research tested how display factors of smartphone (pixel density, sub-pixel structure, luminance) and environmental factor (illumination) affect legibility related discomfort in text reading. The results indicated that legibility related discomfort is largely affected by pixel density, where people experience inconvenience when the pixel density becomes lower than 300 PPI. Illumination has limited effect on legibility related discomfort. Participants reported more legibility related discomfort when stimulus presented in various levels of illumination rather than single illumination level. Sub-pixel structure and luminance did not affected legibility related discomfort. Based on the results we suggest lower limit resolution of smart devices (smartphones, tablet computers) of different sizes for text legibility.

This study analyzed the shot pattern through the tempo of segmented shot duration and studied the relationship with the unique emotion of the story. The structure of the story was classified into 3 chapters, 17 sequences, 83 scenes, 287 beats, and 1636 shots. Shot density is a method of visualizing tension in visual storytelling, and since it is a result obtained by mathematically calculating the density of divided shots, it can be helpful in designing tension delivered to the audience. Nine shot density patterns were extracted. The ascending(+) type was classified as A, B, C, D, 4, the descending(-) type, E, F, G, H, 4, and the maintenance(/) type, I, 1 type. Based on the spatiality of the 17 stages of Campbell's heroic narrative and McGee's story structure, the narrative level of the tree structure was proposed, and the symbolic meaning of the shot rhythm in the practical aspect of the story function was proposed to present a systematic methodology in the direction of production.

The purpose of this study is to define the emotion that expressed in step animation and to quantify the intuitional expression of emotion that related step for using extract, measure, analysis the stimulate element about step. The survey of relation with 27 word of emotional expressions and 36 moving pictures of step sample is used for method of this test. The emotional mental structure is transferred to 2 dimensional planes as applying the results of analysis of integrated data using Quantification Method 3, which the integrated data is composed two axial - confidential axial and stabling axial. Analysis of distribution of 2 dimensional diagram shows that the second of the plane and the third of the plane have much data. However, the first of the plane and the forth of the plane have a little data. Through this kind of analysis of graph, it is difficult to express a different emotion between unstable the timidity mind and stable feel the timidity mind using only step analysis. Six difference types about physical elements affecting to emotion are selected and analyzed such as the paces of step, the rate of step, the movement angle of pelvis, the swing range of arm, angle of backbone and the lean angle of body. The result is that the rate of stop and the lean angle of body are the major element that effects to emotional stimulate of stop. This thesis argues about methods transforming subjective expression to objective and quantitative expression with the state of delicate emotion of character apply to step animation naturally. Those data to apply to multi-contents in future are the main target in this study.

Rational sense is affected by emotion. If we add the factor of estimated emotion by environment information into robots, we may get more intelligent and human-friendly robots. However, various sensory information and pattern classification are prescribed for robots to learn emotion so that the networks are suitable for the necessity of robots. Neural network has superior ability to extract character of system but neural network has defect of temporal cross talk and local minimum convergence. To solve the defects, many kinds of modular neural networks have been proposed because they divide a complex problem into simple several subproblems. The modular neural network, introduced by Jacobs and Jordan, shows an excellent ability of recomposition and recombination of complex work. On the other hand, the recurrent network acquires state representations and representations of state make the recurrent neural network suitable for diverse applications such as nonlinear prediction and modeling. In this paper, we applied recurrent network for the expert network in the modular neural network structure to learn data pattern based on emotional assessment. To show the performance of the proposed network, simulation of learning the environment and behavior pattern is proceeded with the real time implementation. The given problem is very complex and has too many cases to learn. The result will show the performance and good ability of the proposed network and will be compared with the result of other method, general modular neural network.
