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.

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.

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.

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.

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.

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.

Smartphone have become the very important devices in our daily life and provide various roles on impairment and communications of developmental disabilities, acquired neurogenic disorders and autisms. Due to the growth of the technology, an Augmentative and Alternative Communication (AAC) also meets needs and wants, including user customization, configurable layouts and registration of new core vocabulary for individual users. This paper describes the research conducted to design the smartphone-based AAC system. This AAC comprises of a form of communication types such as picture communication boards and sophisticated computer and mobile based devices that can speak in the phrases and sentences for their users. We deployed our AAC system on various sports situations using smartphone systems and also provided user customization method for AAC user's disability levels.

This study is about Augmentative and Alternative Communication as handicapped people actively pursue their life. Especially, although there are many ways and devices for communicating the same as a normal person, descriptive supplementation and sustaining studies are needed for perfect communication as a normal person. The purpose of the paper is to help handicapped people who have hardships about communication. This study develops the function of Smart Workflow AAC(Augmentative and Alternative Communication) and IR sensor_based context aware function that can offer services convenient to classified handicapped people for helping them to communicate effectively. This system from an experimental basis has improved efficiency to communicate more harmoniously within individual handicapped situations to schedule management and communication of handicapped people.

We conducted a user-centered usability testing on the Android-based Mobile Augmentative Alternative Communication(AAC) Software. In this paper, we examined functionality, satisfaction, and ease of information searching for a specific function using a task scenario, and we investigated appropriateness of development purposes, contents, instructional strategies, usability, functions of management mode, and user interface of the mobile AAC to the communication needs of children who are nonverbal. We also examined user requirements, preference, satisfaction, and other personal opinions for the mobile AAC using an open feedback. In addition, we investigated users' preference for the size of mobile devices using 4.3", 5.0", and 7.0" mobile devices.
