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.

The purpose of this study was to investigate targets to use measurement tools to communicate developed in Korea and factors consisting of questions, to examine how measurement tools to communicate applied for AAC subjects were. In the case of measuring language and communication skills targeting people with disabilities, aphasia was out of common, in the case of applying to different types of failures, it showed rare. While factors consisting of questions on measurement tools to communicate had many factors on communication limitations and many factors on impairments in body functions that limit communication, they didn't have a lot of factors on restrictions in participation caused by communication limitations and lots of environmental factors that serve as barriers or facilitators for communication. AAC intervention was applied in the order of physical disabilities, autistic disorder, mental retardation, developmental disabilities, communication disorders, although "PPVT-R", "REVT" were widely used as measurement tools to communicate used in AAC intervention experiment, there were much more cases of relying on observation than standardized tools. Based on the results, we discussed that the need of evaluating to provide ACC application and individualized education(IEP)'s grounds and the research on evaluation criteria and measurement questions should be tried.

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.

In this paper, we implement an AAC(Augmentative and Alternative Communication) system based on image dictionary in order that speech defectives can easily communicate their opinion to others by using images. Normally, those who have a speech defect use only a few limited words to express their intentions and it is an effective way to use images in their communication because they have a difficulty in speaking. Therefore we make verbal images of verb and adjective that play an important role in expressing the speaker's intention, define pattern of semantic relation between the verbal images and noun images, and construct the image dictionary. In this AAC system, when a user clicks a verbal image, the system generates a sentence by selecting noun images which are component parts of corresponding pattern based on semantic relation with the verbal image. We evaluate the implemented system by how efficiently children of speech defect can express their intention and the result shows more than 70% of success rate in communication.

The purpose of this study was to find out the recent trend of high-tech AAC intervention studies for individuals with disabilities. Electronic database searches were completed to identify studies published between 2009 and 2016. 46 studies were identified for inclusion in this review. The studies were classified as participants, research design, intervention settings, independent variables, dependent variables, communication skills by High-tech device, type of high-tech AAC device. Across these studies, intervention was provided to total of 126 participants. Most participants are aged 6-11 and the most common diagnosis was autistic spectrum disorder. Most common study designs were multiple probe design and multiple treatment design. The majority of studies implemented interventions in a special education school(classroom) setting. The majority of studies implemented interventions to compare the effect of high-tech and low-tech AAC device interventions. The majority of targeted behavioral outcomes were communication skills. Tablet PC was the most frequently used for intervention in both domestic and foreign studies. The most common softwares were 'My talky' in domestic studies and 'Proloquo2Go' in foreign studies. The synthesis of evidence describing views of users and providers and the implementation of high-tech AAC device can provide valuable data to inform intervention studies and functional outcome measures. Suggestions for the future research are discussed.

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.

본 논문은 작업 현장에서 청각장애인의 의사소통을 보조하는 한국 수화 메시지 보드의 개발에 대하여 다룬다. 청각 장애인은 일상적인 직업 현장에서 의사소통이 자유롭지 못하여 업무에 잘 적응하지 못하고 사내의 인간관계에 많은 어려움을 겪고 있다. 문자를 이용한 정보 전달을 통해 모든 의사소통을 대체할 수 있을 것이라는 일반적인 생각과는 달리, 청각장애인의 경우 비장애인과 비교하여 사물의 개념 습득에 어려움이 있을 수 있으며 마찬가지로 사용하는 어휘수도 제한적인 경우가 많아 문자를 통한 의사소통에는 명확한 한계가 존재한다. 실제로 청각 장애 근로자가 이직하는 사유로 의사소통이나 인간관계가 높은 비중을 차지한다. 수화 메시지 보드는 크게 사내 네트워크를 이용한 공지 사항 전달을 위한 용도와 복수 개의 메시지 보드 간 문자 송수신의 용도로 사용 가능하다. 비장애인이 청각장애인에게 문자 입력으로 의사를 전달하면, 전달된 문자는 문자-수화 번역기를 통해 자동으로 수화로 번역되어 아바타의 수화 동작으로 화면에 출력된다. 전체 시스템은 수화 아바타를 포함한 그래픽 유저 인터페이스 (GUI), 수화 데이터베이스 및 한글 형태소/문장 분석기를 포함하는 문자-수화 번역기, 그리고 TCP/IP 기반의 문자 전송기의 세 부분으로 나뉜다. 본 논문에서는 수화 데이터베이스의 단어 선정을 위한 대상 작업 현장을 청각 장애 근로자가 타 직업에 비해 많은 비중을 차지하는 전자 부품 조립 업체로 한정하였다. 수화 데이터베이스는 자음 14종, 모음 17종, 숫자 15종, 일상생활 용어 1000종, 전자 부품 조립 업체에 특화된 단어 50종 및 직업 교육 관련 용어 50종으로 이루어진 총 1146종의 수화 단어를 포함하며, 수화 데이터베이스에 등록되지 않은 단어에 대해서는 지화로 표현하도록 한다. 이 중 전자 부품 조립 업체 특화 단어와 관련하여서는, 현재 동일한 분야의 작업 현장이라 하더라도 각 사업장 간 사용되는 수화가 통일되지 않아 문헌 조사 및 현장 조사를 통해 사용 빈도가 높고 형태가 공통적인 50종을 추려내었다. 본 연구는 실제 업무현장에서 청각장애인이 겪는 의사소통의 문제를 효과적으로 해결함으로써, 청각장애인이 직업 현장에 보다 쉽게 적응하도록 도움을 줄 뿐만 아니라, 일을 통해 자아 실현을 하도록 돕는 방안이 될 수 있다는 점에서 중요한 의의를 갖는다.

The purpose of this study was to examine (1) the influence of the word-prediction function on the sentence generation speed and (2) the necessity, convenience, and satisfaction of the word-prediction function of the AAC keyboard. A total of 10 adults with cerebral palsy participated and the word-prediction function of the Korean high-tech AAC device called "MyTalkie Smart" keyboard was used for this study. Participants were required to generate sentence as voice outputs using a word-prediction function and letters direct-input function respectively, then they were required to evaluate the necessity, convenience, and satisfaction using a five-point Likert scale. Other user requirements were examined using a free feedback. The results of this study presented that the sentence generation speeds were faster when participants used a word-prediction function than using a letters direct-input function. However, there was no statistically significant difference between these two input methods, and it might be due to the lack of time to practice the new device. Participants showed positive responses for the necessity, convenience, and satisfaction of the word-prediction function.
