Subjective correspondence among visual variables, auditory variables and vibratory feedback to a hand was experimentally examined to improve usability of a remote controller. First, we studied the correspondence among visual variables represented on a screen or auditory variables and the duration of vibratory stimulus to the subjects' hand by subjective evaluation. Subjective rating method was used in ten items; suitability, comprehensibility, ease-to-use, naturalness, variety, activity, usualness, interest, wish-to-use and feeling of pleasure. Second, to show the effects of multi-modal interface using visual sense, the sense of auditory and vibratory sense, we combined positive stereotype of visual variables and auditory variables provided with the first experiment. The results showed some stereotype between visual variables or auditory variables and duration of vibratory stimulus. Some of the variables such as size, direction of motion, hue, brightness of color and volume of sound had high correspondence with the duration of vibration.

In situations of spatio-temporal perception about visuo-auditory stimulus, researches propose optimal integration hypothesis that perceptual process is optimized to the interaction of the senses for the precision of perception. So, when the visual information considered generally dominant over any other sense is ambiguous, the information of the other sense like auditory stimulus influences the perceptual process in interaction with visual information. Thus, we performed two different experiments to certain the conditions of the interacting senses and influence of the condition. We consider the interaction of the visuo-auditory stimulation in the free space, the color of visual stimulus and sex difference of testee with normal people. In first experiment, 12 participants were asked to judge the change in the frequency of audio-visual stimulation using a visual flicker and auditory flutter stimulation in the free space. When auditory temporal cues were presented, the change in the frequency of the visual stimulation was associated with a perceived change in the frequency of the auditory stimulation as the results of the previous studies using headphone. In second experiment, 30 male and 30 female were asked to judge the change in the frequency of audio-visual stimulation using a color of visual flicker and auditory flutter stimulation. In the color condition using red and green. Both male and female testees showed same perceptual tendency. male and female testees showed same perceptual tendency however, in case of female, the standard deviation is larger than that of male. This results implies that audio-visual asymmetry effects are influenced by the cues of visual and auditory information, such as the orientation between auditory and visual stimulus, the color of visual stimulus.

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.

Background and Objectives: The integration of auditory-visual speech information improves speech perception; however, if the auditory system input is disrupted due to hearing loss, auditory and visual inputs cannot be fully integrated. Additionally, temporal coincidence of auditory and visual input is a significantly important factor in integrating the input of these two senses. Time delayed acoustic pathway caused by the signal passing through digital signal processing. Therefore, this study aimed to investigate the effects of hearing loss and hearing aid digital delay circuit on sound-induced flash illusion. Subjects and Methods: A total of 13 adults with normal hearing, 13 with mild to moderate hearing loss, and 13 with moderate to severe hearing loss were enrolled in this study. Subsequently, the sound-induced flash illusion test was conducted, and the results were analyzed. Results: The results showed that hearing aid digital delay and hearing loss had no detrimental effect on sound-induced flash illusion. Conclusions: Transmission velocity and neural transduction rate of the auditory inputs decreased in patients with hearing loss. Hence, the integrating auditory and visual sensory cannot be combined completely. Although the transmission rate of the auditory sense input was approximately normal when the hearing aid was prescribed. Thus, it can be concluded that the processing delay in the hearing aid circuit is insufficient to disrupt the integration of auditory and visual information.

Such is an elective affinity between literary studies and psychoanalysis that the latter sometime serves as a form of literary pedagogy. The affinity mainly consists in their shared concern for language. The signification of language in psychoanalysis is much similar to that of literature. Many of psychoanalytic terms and theoretical tenets bear witness to its dependence clinically on speech phenomena and theoretically on language in general. It is most true of Sigmund Freud, for whom the unconscious is in effect the linguistic unconscious. The Freudian unconscious, compressing and displacing through images and ideas, works as a text for psychoanalysis, which approach has not only paved one of the ways to poststructuralist anti-essentialism but with which literary studies also feel uncanny familiarity. Freudian psychoanalysis, starting empirically from clinical observations, discovers that words exist independent of meanings in the form of things in the unconscious system. Out of the various sensory elements of a word-thing, in psychoanalytic terms, the auditory is central. Now with the auditory imagination cultivated in the clinic, Freud figures out compression and displacement as the chief unconscious works, of which my main argument is that they are based phonetically on heteronym and homonym associations respectively. Compression and displacement work to be masks, which excites Freud's sense of challenge: his is a kind of poststructuralist approach, in the sense that the closed interrelatedness of words without external referents determines the signification in a given situation. But the works of compression and displacement, viewed in auditory terms rather than mapped on to metaphor and metonymy, can provide a new insight for a literary reading of Freud. Pursuing Freud's auditory imagination is not only an attempt to read his writing as literary text rather than for theoretical discussion, but also an experiment with the possibility of literary reading of a theoretical text in the age of after-theory.

The purpose of this study was to examine the effects of sensory stimulation type on the learning of the elderly. The study implemented elderly verbal learning test by evenly dividing a total of 40 elderly people into auditory stimulation followed by visual stimulation group(AVG), visual stimulation followed by auditory stimulation group(VAG), simultaneous visual and auditory stimulation group(SG), and auditory stimulation group(AG). The result are as follows. SSG showed highest results in most of the test, followed by AVG, VAG, and AG. In particular, SG showed a statistically significant difference in immediate recall total score and short delay free recall score(p<.05). In the post-hoc test results of immediate recall total score, SG showed highest score with a statistical significance. AVG showed the second highest score, followed by VAG and AG and all showed a statistic significance(p<.05).In the post-hoc test results of short delay free recall score, SG and AVG showed a statistically significantly higher score than AG(p<.05). The results suggest that simultaneous stimulation of visual and auditory sense is more effective for improving the learning of the elderly people than visual stimulation followed by auditory stimulation or auditory stimulation followed by visual stimulation.

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.

본 논문은 공감각의 공학적인 응용 및 표현방법에 관한 기초연구로서, 인간이 인지할 수 있는 감각들 중 근감각을 시각 및 청각 요소로 변환하는 기본 시스템의 구축을 목표로 한다. 구축방법으로서, 근감각 신호를 3축 가속도 센서 및 2축 자이로센서로부터 계산된 롤(roll), 피치(pitch) 신호를 통하여 근감각 신호 데이터를 획득하고 그 데이터에서 시각적 컬러 정보와 청각적 정보로 변환하는 방법을 제안한다. 롤 신호는 HSI 컬러 모델의 명도(Intensity)와 청각의 요소인 옥타브(Octave)로 변환하고, 피치 신호는 HSI 컬러 모델의 색상(Hue)과 청각의 음계(Scale)에 대응하여 변환한다. 추출된 HSI 컬러모델의 요소성분들을 기반으로 RGB 컬러모델로 변환한 후 실시간 컬러 출력신호를 얻는다. 또한, 청각의 요소인 옥타브 및 음계 성분을 기반으로 MIDI 신호로 변환, 합성한 후 실시간 사운드 출력신호를 얻는다. 실험에서, 신체의 움직임 즉 근감각을 표현하는 롤과 피치 값에서 색과 음 사이의 유사성에 기초한 변환관계에 따라 정상적인 색과 음이 출력되는 것을 확인하였다.
