The purpose of this study is to analyze the satisfaction and requirements of users' devices after development of tablet based AAC(Augmentative and Alternatice Communication) application for Android. The purpose of this study is to evaluate the satisfaction and the requirement of tablet - based AAC application, Were assessed using the Korea Assistive Technology Assessment Tool (KAAT). As a result of satisfaction evaluation of tablet-based smart AAC device, all the items including device, service, and everyday life showed positive response satisfying from 5 point scale to more than 4 point scale. However, it was relatively low in the items of effectiveness, manipulation and convenience. Some of the improvements in the application include the enlargement of the symbol sound and the simplicity of symbol editing. The results of the study suggest that continual updates of m Smart AAC applications, the simplicity of symbolic editing, application usage and training should be improved. The satisfaction evaluation results of this study and the feedback of potential users will be the guidelines for improving and complementing the functions of existing smart AAC devices.

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.

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.
