시각장애인의 보행을 유도하기 위한 전자보행기로, 소닉가이드, 모와트센서, 바이오닉 지팡이 등이 개발되었으나, 가격이 비싸거나, 훈련이 어렵다는 이유 등으로 국내에서는 거의 보급되어 있지 않고 있다. 따라서, 본 연구에서는 청각에 의한 장해물을 인식 개념을 고려하여 주변의 장해물의 파악에 특별한 훈련이 필요치 않으며, 저렴한 가격의 전자보행기의 개발 을 위한 기본 연구로 시각장애인의 장해물인지특성의 검토 및 장해물 인지특성을 고려한 초음파형 전자보행유도기의 프로토콜을 통한 보행시험을 실시하였다.

인터넷의 급속한 발전으로 다가온 디지털 시대는 인간의 삶을 더욱 비접촉적으로 만들어간다. 촉감은 시각과 청각에 비해 중요성이 크게 인식되지 못하지만, 제품의 질을 결정하는 중요한 역할을 한다. 본 연구는 촉감이 중요한 요소이지만 촉감을 직접 느낄 수 없는 환경에서 시각과 청각을 통해 촉감을 느낄 수 있는 방법을 연구하여, 시/청각적 촉감 인터페이스를 구현하는데 목적이 있다. 따라서 본 연구는 시/청각적 촉감 요인을 규명하고, 이를 인터페이스 디자인에 적용 및 평가하였다. 이를 위해 우선 시/청각적 촉감인터페이스의 개념을 제안하고, 시/청각적 촉감인터페이스를 이해하기 위해, 촉감의 신경학적, 생리학적 메카니즘을 연구하였다. 두 번째로 시/청각적 촉감의 요인을 11가지의 감성적 촉감요소와 여러 가지 디자인 촉감요소로 추출하고, 두 요소의 상관관계를 분석하였으며, 이를 시/청각적 촉감 인터페이스 디자인 체크시트를 통해 손쉽게 적용할 수 있도록 하였다. 마지막으로 인터넷 쇼핑몰에서 의류 및 용기를 대상으로 실험 한 후, 13% 상승된 신뢰도를 얻을 수 있었다. 따라서 시각과 청각을 통한 촉감 구현은 가능성이 매우 높은 것으로 평가되었다. 본 연구는 인터넷 쇼핑몰, 가상 현실 등과 같이 촉감이 중요한 요소이지만 실재로 만져볼 수 없는 대상에 매우 유용하게 적용될 수 있을 것으로 전망된다.

The concept of human emotion is recently demanded to be imbedded in industrial product and environment for enhancing quality of life. Human emotion is attempted to be qualified and quantified by physiological measurements. EEG variation, one of the physiological measurement, is observed to characterize psychological response in this study. This study is to find function and process of brain according to emotion. Twenty university students participated in this study and experienced positive and negative emotion by auditory stimulus. Delta, theta, alpha and beta waves showed characteristic variation in normalized sense according to positive and negative emotion. Local area showing significant difference between positive and negative emotion decreases with stimulus duration. Delta, theta and beta waves increase with negative emotion while alpha wave does with positive emotion.

Psychological action is physiological response of outernal stimulus. Physiological response is accompanied b physiological signals which are EEG, EMG, GSR, ECG, BP, and tec. Physiological signals are recently studied for determination of human phychological state. Psychological activity causes electric potential of brain. Physiological signal is considered as measurement of human psychological state. Aditory sensibility which is one of the sense of human may determine differences between positive and negative feeling. EEG and GSR variation with auditory quality of stimulus can be define human negative and positive mental state. This study is to characterize parameters which can determine negative and positive psycholigical state of human.

This paper presents a method for conversion of muscular sense into both visual and auditory senses based on synesthetic perception. Muscular sense can be defined by rotation angles, direction changes and motion degrees of human body. Synesthetic interconversion can be made by learning, so that it can be possible to create intentional synesthetic phenomena. In this paper, the muscular sense was converted into both color and sound signals which comprise the great majority of synesthetic phenomena. The measurement of muscular sense was performed by using the AHRS(attitude heading reference system). Roll, yaw and pitch signals of the AHRS were converted into three basic elements of color as well as sound, respectively. The proposed method was finally applied to a wearable device, Samsung gear S, successfully.

This study is to observe human observe human positive and negative sensibility according to modalities such as auditory, visual, olfactory and tactile sense. Twenty university students are participated in this study. Experiment is performed in the subject room specially designed. Measurement system is Spectrum 32 (Cadwell) and is capable of brain mapping. The results shows brain local areas showing statistically significant difference between the positive and negative sensibility in ergonomics.

최근, 동물에 대한 객관적 이명 유무 검사인 GPIAS (gap prepulse inhibition of acoustic startling) 방법이 보고된바 있으나 동물과 달리 큰 자극음에 의한 놀람 반응 (startling response)을 사람에게서 측정하는 것은 어렵기 때문에, 청성 유발 반응과 같은 뇌파 신호를 측정하는 것이 사람 이명 검사법 연구에 보다 적합하다. 본 연구에서는 GPIAS 방법에서 사용하는 gap prepulse 기반의 소리 자극법을 자유롭게 적용할 수 있으며, 청각 심리학적 현상인 이명과 연관된 대뇌 피질 활동을 반영하는 청성 후기 반응 (auditory late latency response, ALLR) 뇌파를 간편하게 측정할 수 있는 청성 후기 반응 측정 시스템을 구현하였다. 또한, 구현된 시스템을 정상 청력을 가진 8인의 피험자에게 적용하는 실험을 통해 gap prepulse 기반의 소리자극에 의한 청성 후기 반응의 N1-P2 첨두치 크기를 측정하였고, gap prepulse에 의한 N1-P2 억제율 현상을 확인 및 평가하였다. 이를 통해, 구현된 청성 후기 반응 측정 시스템이 향후 gap prepulse 소리 자극법에 기반한 객관적 이명 검사법 연구 및 검증 도구로서 이용될 수 있음을 확인하였다.

Jazz derived from the blacks' work songs and made the frame of Jazz reaching blues and finally arrived at the recent time propagating itself as not only the blacks' music but all human being's music. This study has a purpose to suggest the Jazz image to the fashion design by examining the historical trace of Jazz which is one of popular music received by hearing sense. As for the result of the Jazz's effects by age, rhythmical beauty stressing dresses were in fashion by dance enjoying women in 1920's and dresses giving a mature atmosphere set the fashion in 1930's. in the beginning of 1990's, newly emerging Jazz was reflected to the popular culture along with the historical mode's fashion in the general society. The design's decided with two themes of Jazz Classic and Neo Fusion to modernly and naturally express the pursuit of strong color contrast which associated fast rhythm and lax image such as the counter melody of smooth Jazz. In that result, Jazz image with auditory feelings could suggest the various design motive and new idea to fashion design.

Each reproducing speech signal has each particular signal property, because of the processing of encoding and decoding for communications through various media. In this paper, we examine the correlation between speech signal quality and sensory pleasure for the sensory improvement of that signal. In experiments, we evaluate the quality of speech signals through various media by psychological auditory test and physical features of these signals.

Although past design developments that emphasized only the outer appearances of products were mostly concentrated on the areas of forms and colors in an attempt to satisfy humans' visual needs, it is expected that future designs to come will go in the direction to stimulate more diversified human senses. This means expansions to the five senses including the auditory sense, the sense of smell, the tactile sense and the taste and even to the area of synesthesia where two or more senses are stimulated or coexist. Although the dictionary definition of synesthesia is a concept of arousing another sense through a sense, studies of synesthesia in design go one step further from here to mean compound senses, that is, the synesthesia in an expanded meaning to feel an object (thing) through many sensory organs simultaneously. The synesthesia in the expanded meaning is applying multiple senses simultaneously in recognizing one thing to comprehensively judge and feel the thing. Recent design trends are going in a direction to basically satisfy humans' visual needs through controlled forms and colors while inducing another new feeling through expressions of diverse feels of materials within existing forms. In this change of the times, studies on furniture designs are conducted through factors of in synesthesia linked with other senses and have an important meaning that can enhance the value of designs.
