응급 의사소통 시스템(ECS)은 세심한 계획, 설계시공 및 사용이 요구된다. 음성으로 메시지를 전달하는 시스템은 수많은 사용자, 관계당국, 종사자 및 전문가와 관련된 수많은 도전에 직면해 있다. 관련 당사자와 전문가가 결정되고 응급 의사소통 시스템(ECS) 프로젝트의 초기 설계 단계부터 포함되도록 하는 것이 중요하다. 음성 전달 시스템은 통상적인 화재 경보 시스템과는 많이 다르기 때문에, 엔지니어는 새로운 기술을 적용하고 새로운 설계 기법 또는 경험이 있는 새로운 전문가를 찾아 협력해야 한다. 관계 당국과 건물주는 응급 의사소통 시스템(ECS)의 설계에 적극 참여해야 한다. 응급 의사소통 시스템(ECS)의 음성 메시지를 무시하거나 부분적으로만 전달하는 것은 응급 상황 시 음성을 이용한 의사소통의 효과와 품질을 위태롭게 하는 것이다.

정보사회와 함께 무선 인터넷이 발달하고 모바일 기기를 이용해 많은 정보들이 교류되면서 교육분야에서도 모바일기기 및 첨단 매체들이 활용되고 있다. 본 논문의 목적은 자폐아동의 의사소통 기능을 향상시키기 위하여 여러 논문을 성찰하여 강화된 환경중심 언어중재 (Enhanced Milieu Teaching : EMT)를 활용하여 의사소통을 신장시킬 수 있는 모바일 프로그램을 설계하였다. EMT는 아동의 기능적 의사소통을 촉진하는 환경 조절 전략과 상호작용을 촉진하는 반응적 상호전략을 결합하여 중재하는 것으로서 본 시스템의 특징은 다음과 같다. 첫째, 학교생활에서 의미있게 반복될 수 있는 5가지 상황을 주제 내용으로 선정하여 의사소통 목표어와 상황의 유기적인 관련성을 갖고 의사소통 능력을 학습하고 효과를 높일 수 있도록 설계하였다. 둘째, 시간과 공간의 제약을 벗어날 수 있는 모바일 시스템을 활용하여 무한하게 반복할 수 있음으로써 의사소통 목표어의 일반화에 도달할 수 있는 시간을 절약할 수 있다. 셋째, 학습자의 수준에 따른 개별적, 수준별 STEP을 제공하며, 의미 있는 상황을 통해 의사소통 목표어를 학습하게 되므로 자폐성 아동의 자발적 의사소통에도 긍정적인 영향을 제공할 수 있다.

Augmentative and Alternative Communication(AAC) is the widespread supporting plan to solve the communication problem of the people with communication disorder. AAC means various types of non-verbal communication methods that are used to augment or substitute the communications of using speech. With the increasing number of potential Korean AAC users, the demands for AAC are also increasing. In spite of the increasing demands, AAC is not being actively and practically used. In this paper, we implemented a web-based AAC board making system, where the board-makers (special educators and speech therapists) can create and share the customized boards to help the board-users (people with communication disorder). The web-based AAC board making system contributes to the application of AAC in many societies, such as hospitals, schools, companies, or anywhere the AAC intervention is needed.

The person who gets a ALS(Amyotrophic Lateral Sclerosis) has language disability and physical disability together. A common first symptom is a painless weakness in a hand, foot, arm or leg, which occurs in more than half of all cases. Other early symptoms include muscle weakness of speech. In the early stage of this disease they can communicate with other persons, but it will become increasingly difficult. In our research we have designed and implemented communication tools for them. We have implemented Chunjiin(the Korean computer keyboard) at PDA(personal digital assistant). And we have also implemented software which is consisted of frequently used words.

It takes a lot of time or is even impossible to communicate for people with physical disability and/or speech impairment. Augmentative and Alternative Communication System is an important computerized tool that makes it possible for those people to communicate. Since not only speech impaired people, but also people with other physical disability cannot use conventional computer input devices easily such as keyboard and mouse, so more simple input devices are need for them to communicate. Thus, in this paper, I designed and implemented a communication aid system, with which they can communicate with simple inputs. I collected frequently used sentences by people with disability and categorized them into 9 everyday language groups. With these categories, they can select any sentence with few simple selections. If none of these categories includes the sentences they want, ChunJiIn keyboard is provided so that they can input the sentences, which can be added to the existing language groups for later use. The priority levels of the sentences in each group is constantly readjusted based on usage frequency so that the number of inputs can be reduced.

The present study implemented AAC(Augmentative and Alternative Communication) system using images that speech defectives can easily understand. In particular, the implementation was focused on the portability and mobility of the AAC system as well as communication system of a more flexible form. For mobility and portability, we implemented a system operable in mobile devices such as PDA so that speech defectives can communicate as food as ordinary People at any Place using the system Moreover, in order to overcome the limitation of storage space for a large volume of image data, we implemented the AAC system in client/server structure in mobile environment. What is more, for more flexible communication, we built an image dictionary by taking verbs as the base and sub-categorizing nouns according to their corresponding verbs, and regularized the types of sentences generated according to the type of verb, centering on verbs that play the most important role in composing a sentence.

This study aims to develop communication devices and interfaces to address the communication needs of the hearing impaired. Through three FGI (Focused Group Interview)s with deaf persons and sign-language interpreters, we studied the communication methods, devices, and needs of the deaf. On the basis of our analysis, we propose a communication framework to improve their means of communication with normal or other deaf persons. We have designed a communication system that is based on the proposed framework: this system suggests functions for remote sign-language interpretation services for conversations in close-range and over the phone. Details are presented regarding the design of interfaces for video calls, text messages, and digital memos, addressing the conversation patterns of the deaf. The system includes hardware form factors for video phones that facilitate sign language conversations and also mitigate other auditory problems in daily life, such as problems with door bells. The design concept has been verified through a test with six deaf users.

Augmentative and alternative communication(AAC) is a communication tool for those with impairments or restrictions on the production or comprehension of spoken language. Traditional AAC has used a portable board with pictures and texts with which disabled person could be supported by it. Currently, smart phone based AAC researches and developments are actively studying. With emerging concepts of context-aware computing, the mobile devices can provide mobile users with timely information and location based services. We proposed a adjustable AAC system for disabled people of which has variable layouts and selectable items. We also implemented context-ware application for AAC systems including time, location and click count informations on smart phone. The system can adaptively change its layout and select AAC items depending on various situation of disabled persons.

우리가 다른 이들과 만나 대화하는 것은 극히 평범한 일이다. 하지만 대화뿐만이 아니라 의사소통마저도 힘들어하는 이들이 있다. 이들은 언어 장애를 가진 이들이다. 언어 장애에는 태어나면서부터 장애를 가지는 선천적 장애와 사고와 질병으로 인한 후천적 장애가 있다. 그 중 후천적 장애는 언어장애와 더불어 신체적 장애를 가진 이들이 있다. 이들을 본 논문에서는 중증 언어 장애인이라고 분류하였다. 중증 언어 장애인의 장애정도를 크게 글자 표현이 불가능한 상태로부터 4가지 단계로 나뉠 수 있다. 글자 표현이 불가능하지만 개체 선택이 가능한 1단계, 손 혹은 발을 이용하여 가부 결정만 가능한 2단계, 지체를 이용하여 표현이 불가능한 3단계, 그리고 마지막 4단계가 3단계의 표현마저도 불가능하여 의사소통이 전혀 불가능한 상태이다. 사고로 인한 후천적 장애인 경우 위의 4가지 단계중 하나의 단계에서 머물러 있지만, 루게릭병과 같은 병은 위의 4가지 단계를 몇 년에 걸쳐서 진행되기 때문에 일반적인 장비로써는 이 들과의 의사소통이 불가능하다. 본 논문에서는 위의 1,2,3단계의 중증 언어 장애인을 대상으로 그들이 의사소통을 정확하고 신속하게 전달하기 위해서 어떠한 인터페이스를 사용하는 것이 효과적인 방법에 대해 논해보고, 향후 발전될 방향에 대해서 그 방향을 제시하였다.

A communication is one of the most important factors for the human beings. Therefore, people who have some problems in communication need an Augmentative & Alternative Communication (AAC) intervention to live in the human societies and several AAC systems have been developed to help the people. Lately, smart-phone is widely used to people as a communication device which can connect between persons. It can provide many useful methods and Apps to the user. If the AAC system is unified to the smart-phone, it is very effective device to the people with disabled because they can reduce the excessive expense and easily accommodate themselves to the AAC system. In this paper, an AAC program which is installed in the smart-phone or tablet PC is introduced. It has basic AAC solutions and can send SMS message to other people. We expect that the developed device can help the communication of the people with disabled and solve the social isolation of the disabled person.
