In this study, specific elements and functions in modules of the AAC (Augmentative and Alternative Communication) application for children with severe and multiple disabilities were elicited, and screen interface was designed accordingly. As results, screen configuration, communication display edition, audiovisual output, and switch and scanning modules were defined. Screen configuration module consists of communication category, spelling board, favorites, screen lock, and setting function. The Communication display edition module includes communication categories, symbols, and favorites edition. The audiovisual output module provides the ability to adjust the pitch, intensity, speed, and tone of the voice individually in the form of auditory output. In the form of visual output, the background color and size of the frame, border color and thickness are adjusted. The switch and scanning module provides a function to select by pressing the switch when the symbol cell is highlighted audibly and visually. The development of the AAC application designed in this study is needed.

Recently in the mobile market, the communication technology which bases on the sense of sight, sound, and touch has been developed. However, human beings uses all five - vision, auditory, palatory, olfactory, and tactile - senses to communicate. Therefore, the current paper presents a technology which enables individuals to be aware of other people's emotions through a machinery device. This is achieved by the machine perceiving the tone of the voice, body temperature, pulse, and other biometric signals to recognize the emotion the dispatching individual is experiencing. Once the emotion is recognized, a scent is emitted to the receiving individual. A system which coordinates the emission of scent according to emotional changes is proposed.

According to the Ministry of Science, ICT and Future Planning's survey of information gap, smartphone retention rate of disabled people stayed in one-third of non-disabled people, the situation is significantly less access to information for people with disabilities than non-disabled people. In this paper, we develop an application, CallHelper, that helps to be more convenient to use mobile voice calls to the auditory disabled people. CallHelper runs automatically when a call comes in, translates caller's voice to text output on the mobile screen, and displays the emotion reasoning from the caller's voice to visualize emoticons. It also saves voice, translated text, and emotion data that can be played back.

The purpose of the present study was to compare and analyze the differential effects of in-vehicle electronic device usage types(searching for targeted destinations in navigational purpose, watching TV in entertain purpose, and dialing a cellular-phone in phone-usage purpose) on driver's front-to-rear-end collision avoidance behavior, and to find effective collision warning format for this behavior. The result indicated that (1) the drivers showed more impaired collision avoidance performances when they were asked to search the name of targeted destination than the other task requirements, and (2) auditory warning appeared to be most effective among the other types of warning. In particular, it was suggested that the "Visual-Only" collision warning could induce most undesirable result when the drivers were engaged in both visual and auditory information processing.

멀티미디어(Multimedia) 시대에 있어 메시지(Message)를 통한 사회적 상호작용, 즉 커뮤니케이션 (Communication)은 시각적인 요소, 색채, 형태, 시간, 움직임 뿐 만 아니라 청각적인 요소도 메시지를 전달하는 표현요소로 자리 잡고 있다. 왜냐하면 시각이나 청각 어느 하나만으로 메시지를 전달할 때보다 시 청각을 조화시켜 메시지를 전달 할 경우에 인지도가 훨씬 높기 때문이다. 그리하여 본 연구는 영상 커뮤니케이션이 가지고 있는 시 청각적 요소들의 연관성을 찾고자 하였다. 오늘날 TV 이나 영화 인터넷 등등의 멀티미디어에서 우리는 정보전달과 설득의 영상 메시지들을 쉽게 접할 수 있다. 그 중에 특히 영상메시지의 역할을 극적으로 나타낼 수 있는 광고영상에 속한 시각적 요소 타이포그래피와 청각적 요소 사운드를 통해서 시 청각적 요소의 연관성에 대해 연구하였다. 먼저 다양한 광고영상을 소구방법과 내용에 따른 분류를 통해 분야별로 나누고 그 분야에 따른 시 청각요소의 사용 빈도와 유형을 조사하였다. 타이포그래피는 전달방법에 따라, 사운드는 사용 유형에 따라 나누어 빈도와 유형을 조사하였다. 영상의 시각요소와 청각요소의 적절한 사용이 수용자로 하여금 선호도 및 인지도에 높은 효과가 있다는 분석 결과를 가지고 국내와 국외 광고영상의 시 청각요소의 분포도를 조사, 분석하였다. 그리하여 향후 효과적인 영상 커뮤니케이션의 역할을 하기 위해 시 청각요소의 연관성을 고려한 효율적인 광고영상 제작방향을 제시하고자 한다.

Artificial cochlear implant system is known as the most efficient and widespread device to patients who have cochlear disorder. However, current commercialized artificial cochleas have inconveniences because of large volume size and high power consumption, requiring further research on improvements in terms of the size, power, and performance. In this paper, we will introduce our fully implantable artificial cochlear implant system, where small-size sensors and actuators are wirelessly connected, focusing on communication system design and its performance simulation.

A new form of media is changing the expression and content of fashion. In this paper, fashion films that have appeared since 2010 - when digital fashion communication was increasing - will be discussed and explored to consider how technological transitions in fashion media are changing the appearance and role of fashion. A literature review was conducted to derive characteristics, types, and expressive elements of new media fashion films, which were defined for this study as fashion films produced and distributed since 2010 using digital media. Films were categorized into three types: promotional, editorial, and independent fashion films. Furthermore, elements of the films were identified as fashion mise-en-scene, auditory structure, and content structure. Types and expressions of digital fashion images in 40 fashion films were analyzed according to these elements. The results showed that promotional fashion films maximize various narrative and sensory effects on fashion products, whilst editorial fashion films strengthen the role of entertainment. Independent fashion films expand the area of fashion and promote the diversification of fashion systems. Moreover, the results show that fashion films are not a secondary form of media that just expresses fashion; they provide a tool for the creation of new fashion content. New media fashion films promote the expansion of expressive spectra and boundaries, offering various multisensory experiences of fashion, and enhancing creativity and the aesthetic values of fashion.

This study is study regarding system implementation that a ruler maximizing an autoimmunity effect supported it as I stimulate I am visual hearing so that treatment ability is possible. As I am known in a lot of conspiracy mental problems by being disproportionate for a direct reason to be connected to an action, the brain whom emotional, govern spirits through fragrance to stimulate sense of smell so that, specially, an ARoMa treatment is effective. I will inquire into changes and an influence around alpha of the rear wave object before watching this system.

Emerging trends in the area of digital very large scale integration (VLSI) signal processing can lead to a reduction in the cost of the cochlear implant. Digital signal processing algorithms are repetitively used in speech processors for filtering and encoding operations. The critical paths in these algorithms limit the performance of the speech processors. These algorithms must be transformed to accommodate processors designed to be high speed and have less area and low power. This can be realized by basing the design of the auditory filter banks for the processors on digital VLSI signal processing concepts. By applying a folding algorithm to the second-order digital gammatone filter (GTF), the number of multipliers is reduced from five to one and the number of adders is reduced from three to one, without changing the characteristics of the filter. Folded second-order filter sections are cascaded with three similar structures to realize the eighth-order digital GTF whose response is a close match to the human cochlea response. The silicon area is reduced from twenty to four multipliers and from twelve to four adders by using the folding architecture.

In this study, multi-channel digital hearing aid algorithm for low power system is proposed. First, MDCT(Modified Discrete Cosine Transform) method converts time domain of input speech signal into frequency domain of it. Output signal from MDCT makes a group about each channel, and then each channel signal adjusts a gain using LCF(Loudness Compensation Function) table depending on hearing loss of an auditory person. Finally, compensation signal is composed by TDAC and IMDCT. Its all of process make progress 16-bit fixed-point operation. We use fast-MDCT instead of MDCT for reducing system complexity and previously computed tables instead of log computation for estimating a gain. This algorithm evaluate through computer simulation.
