This paper deals with the construction of database system for the human sensibility evaluation.Recently, although a great deal of research efforts have been made to find out the relationships between products and emotion, the main focus of studies have been on visual and auditory sense and less on human sensibility evaluation. Therefore, we think that continuous and systematic studies on odors and the construction of database system are strongly needed in order to enhance the competitive power of products related to them.In this paper, we developed a human sensibility evaluation database system fitted with the characteristics of our country. 쏜 design procedures of database system are presented. According to these procudures, a new database system is implemented on personal computer using MS Access and Visual and is validated.

Categorization in a vital means for dealing with the multitudes of entities in the world surrounding people. Among others, the perceptual and the evaluative similarities factors strongly affect categorization. The conventional SD-type procedure are insufficient in this regard, since it requires an individual subject to make isolated judgments about each stimulus to identify categorization in terms of a group tendency. It disregards the individual categorization in which the similarities are of great importance. Thus in this study the phased emotional evaluation method is suggested based on the intuitive categorization of stimuli and on the similarity judgement of representative/ non-representative case in each category. To verify the effectiveness of the suggested evaluation method the scanned jewelry images are selected as test stimuli for emotional evaluation experiment. As a result of the evaluation experiment, the conventional SD-type procedure is complemented by the emotional evaluation method in phases of the task of intuitive categorization, the selection of the representative images and the setup of the evaluation score of the representative images to internally supplied anchors of evaluating non-representative images.

In this paper, the comparison of speech feature parameters for emotion recognition is studied for emotion recognition using speech signal. For this purpose, a corpus of emotional speech data recorded and classified according to the emotion using the subjective evaluation were used to make statical feature vectors such as average, standard deviation and maximum value of pitch and energy. MFCC parameters and their derivatives with or without cepstral mean subfraction are also used to evaluate the performance of the conventional pattern matching algorithms. Pitch and energy Parameters were used as a Prosodic information and MFCC Parameters were used as phonetic information. In this paper, In the Experiments, the vector quantization based emotion recognition system is used for speaker and context independent emotion recognition. Experimental results showed that vector quantization based emotion recognizer using MFCC parameters showed better performance than that using the Pitch and energy parameters. The vector quantization based emotion recognizer achieved recognition rates of 73.3％ for the speaker and context independent classification.

본 연구에서는 쾌, 불쾌, 긴장, 이완의 네 가지 상상을 통해 감성의 변화를 유도하였고, 생리 신호 분석을 통해 감성의 변화를 변별하고자 하였다. 20명의 피험자를 대상으로 네 가지 상상을 각각 30초씩 수행하게 하면서 EEG, ECG, GSR, PPG, RSP, Skin-Temperature를 각각 측정하였고 측정 종료 후 주관적 평가를 실시하였따. 주관적 평가 분석 결과, 피험자는 뚜렷이 구별되는 네 가지 상상을 한 것으로 나타났고, 쾌도는 “쾌 > 이완, 긴장 > 불쾌” 상상 순서의 3단계로, 긴장도는 “긴장 > 불쾌, 쾌 > 이완” 상상 순서의 3단계로 뚜렷이 구별되었다. EEG 분석 결과에서는 쾌와 불쾌, 쾌와 이완 상상 사이에서만, 자율신경계 반응 역시 약 2.5 단계의 긴장도 감성 변별이 가능하여 정확한 3단계의 감성 변별에는 어려움이 있었다. 그러나 향후 비선형 분석법을 적용하고 피험자 수를 증가시킨다면 생리 신호 분석을 통한 감성 변별 민감도를 증가시킬 수 있을 것으로 사료된다. 본 연구로부터 쾌/불쾌와 긴장/이완의 2차원의 감성 영역의 각 축을 EEG와 자율신경계의 생리 신호를 통해 변별할 수 있다는 가능성을 확인하였다.

This paper presents two kinds of new approaches, one of which is concerned with recognition of emotional speech such as anger, happiness, normal, sadness, or surprise. The other is concerned with emotion recognition in speech. For the proposed speech recognition system handling human speech with emotional states, total nine kinds of prosodic features were first extracted and then given to prosodic identifier. In evaluation, the recognition results on emotional speech showed that the rates using proposed method increased more greatly than the existing speech recognizer. For recognition of emotion, on the other hands, four kinds of prosodic parameters such as pitch, energy, and their derivatives were proposed, that were then trained by discrete duration continuous hidden Markov models(DDCHMM) for recognition. In this approach, the emotional models were adapted by specific speaker's speech, using maximum a posteriori(MAP) estimation. In evaluation, the recognition results on emotional states showed that the rates on the vocal emotions gradually increased with an increase of adaptation sample number.

Objective: The aim of this study is to find the optimal values of sliding factors which influence the mechanical emotion of users when they use sliding type mobile phones. Background: There are various researches that study the emotion of using mobile phones. They focus the correlation between emotion words and design factors and use the commercial products by the subjects in the experiment. However, it has a limit in finding the optimal point of emotional factors because we can search the restricted values in the mass production of the products. Therefore, we will find the optimal points by realizing the full range of the user's mechanical emotion. Method: First, we need to get the detailed factors which can describe the mechanical emotion in sliding up and down the mobile phone. Next, we find the control factors by considering the correlation between the factors of the sliding emotion and the possibility of quantitative design. To find the optimal points on the control factors, we make a sliding evaluation system which can help users feel the sliding mechanical emotion by realizing control factors. Finally, we find the optimal points by doing the experiment the system being used. Results: The critical values of the factors which are the main variables of this study are Open Max Force and Dead point Ratio. The optimal point of the Open Max Force is 200~250g/f, and the Dead point Ratio is 40~50%. Conclusion: In this study we develop the sliding evaluation system to realize the control factors of the sliding type phone and find the optimal values of the critical factors. Application: The results can be used as the criteria for designing sliding type phone.
