This paper presents the novel feature selection method for Emotion Recognition, which may include a lot of original features. Specially, the emotion recognition in this paper treated speech signal with emotion. The feature selection has some benefits on the pattern recognition performance and 'the curse of dimension'. Thus, We implemented a simulator called 'IFS' and those result was applied to a emotion recognition system(ERS), which was also implemented for this research. Our novel feature selection method was basically affected by Reinforcement Learning and since it needs responses from human user, it is called 'Interactive Feature Selection'. From performing the IFS, we could get 3 best features and applied to ERS. Comparing those results with randomly selected feature set, The 3 best features were better than the randomly selected feature set.

This study researches the effectiveness of interactive TV advertising focusing on the factors of audience involvement and interaction. The study began with the effective measurement of interactive television advertisements. Interactive television advertisements have different concepts than existing television advertisements. This study mainly focuses on the characteristics of audience interaction and experiments based on the data of 78 persons for measurement. In the experiments, the characteristics were categorized according to search time, specifically the number of searched pages about interactive television advertisement. Hypothesis 1 reveals that the interaction of the audience increases when the advertising attitude, brand attitude, and purchase intentions also increase. Hypothesis 2 finds that the involvement of the audience increases when the advertising attitude, brand attitude, and purchase intentions also increase. By studying these consumer characteristics and behavior, a new method of effective measurement for interactive television advertisement is uncovered. The new method includes not only existing measurement elements of television advertisement which include attitude about advertising and brand, and customer purpose, but also the features of interactive television advertisement like customer search time. According to this research on interactive television advertisement, the interaction with and involvement of the audience are highly influential variables.

Truck dispatching is one of the most commonly occurring problems of transprot management. We developed an interactive decision support system named IDSSTD, for the truck dispatching problem where two conflicting objectives are treated and travel speed varies depending on the passing areas and time of day. The IDSSTD aids the decision-making process by allowing the user to interact directly with the database, to direct data to a decision model, and to portray results in a convenient form. The IDSSTD is consisted of two major interactive phases. The pre-scheduling interactive phase is to reduce the complexity of a given problem before applying the BC-saving heuristic algorithm and the post-scheduling interactive phase is to improve practically the algorithmic solution. The IDSSTD has the capabilities of its own manipulation(analysis and recommendation) and diverse graphic features in order to facilitate a user's interaction.

Purpose of this study is to analyze the meaning of the hybrid digital culture and to find out the features of digital fashion shows appearing in the period of the hybrid digital culture as there have been almost no studies on the hybrid cultural values in the fashion shows and on the diachronic socio-cultural viewpoint of fashion show. The characteristics of hybrid digital culture were identified through the analysis of cases, and they were organized into three for this study; 'non-economic creativity', 'interactive communication' and 'transcendence'. Based on these characteristics, the features of hybrid digital cultures in the modern digital fashion shows were classified into the digitalization of presentation form and the acceptance by audience of digitalization using case studies. The features of digital fashion shows which appear through the presentation form in the digital fashion shows are as follows; 'Expansion of presentation media of runway' and 'Destruction of component factors of runway'. The features of digital fashion show in the perspective of audience's acceptance of digitalization are as follows; 'Audience's field experience through the live video', 'Participation by audience in interactive manner' and, 'Immersion in the virtual reality by the audiences'.

Interactive art is implemented by participants interaction, characterized by the virtuality, immersion, interactivity. Among these features, immersion is important factor to absorb in the interactive art. From now, Interactive art measurement methods are mainly used in interview, questionnaire, and physiological methods. But these methods are difficult to measure the exact immersion, can give interfere with viewer's participation in the interactive art. In this paper, we propose the immersion measurement method which based on participant's moving lines, observation time with mobile devices, camera. This paper can help to analyse degree of immersion on interactive art.

The ideologie of modern society as per something to phenomenology problem is to show various different looks. The community space is spring from Greek and Roman of community place by agora and forum is make a active communicate to interpersonally. Subject to centrically In the context, this paper is study on the Sustainable development for community space about interactive space. and focusing is Response to human of interact in each other intelligent space. And this paper suggestion is composition method of community space in technology advanced, Interactive interface form for human, sustainable to community space direction elements. First, I'll rearrange the distinctive features of modern society through references of various scholars. This is to understand how interactivity affects the whole society and what is the importance of this interactive wave. Second, I'll analyze several trends of modern community space and figure the change of methodology of design based on the advancement of design technology. This is to understand the interactive relation of the subjects. Third, I'll seek how community space design has changed in modern society and under which process design is made. This is to clarify the fact that the portion of interaction will increase in future design according to the intervention of equipment, which is one of the objects of interaction space.

Media art is developing the art of 'interaction' that get meaning through communicating an audience. Now, media art got the title named interactive media art, but its concept is not clear In this study we divided into two classes - passive and active interactive art. Passive interactive art had the interaction 'participation of communication' and had flat and limited features. Active interactive art meant that an audience played with works actively and found significances between artworks and themselves. Through analysis of case study, we verified a propriety about own interactive art's division. Especially, the active interactive art was very important. The western classical metaphysics seemed to be not perfect in analysis of active interactive art. We tried to analyze active interactive art more perfectly by using the oriental philosophy.

Recently, in the field of Speech Emotion Recognition (SER), many studies have been conducted to improve accuracy using voice features and modeling. In addition to modeling studies to improve the accuracy of existing voice emotion recognition, various studies using voice features are being conducted. This paper, voice files are separated by time interval in a time series method, focusing on the fact that voice emotions are related to time flow. After voice file separation, we propose a model for classifying emotions of speech data by extracting speech features Mel, Chroma, zero-crossing rate (ZCR), root mean square (RMS), and mel-frequency cepstrum coefficients (MFCC) and applying them to a recurrent neural network model used for sequential data processing. As proposed method, voice features were extracted from all files using 'librosa' library and applied to neural network models. The experimental method compared and analyzed the performance of models of recurrent neural network (RNN), long short-term memory (LSTM) and gated recurrent unit (GRU) using the Interactive emotional dyadic motion capture Interactive Emotional Dyadic Motion Capture (IEMOCAP) english dataset.
