Communication disabilities means the case that one cannot express one's intention or that one cannot accept other's speech. Most of severe and multiple disabilities that the disability degree is serious, or that have more than two disabilities have communication disabilities. The augmentative and alternative communication device to promote these students' communicative competence can be a big help to improving disabled students' competency.
Though the necessity of the production and distribution of the electronic augmentative and alternative communication device using the modern information and communication technology for the disable students is being presented, it is difficult for the disable students to purchase and use them because most of them are foreign products and are not suitable for Korea's cultural environment, or inconvenient for the use and the considerable prices.
This paper aimed at designing a low-cost augmentative and alternative communication device of an intermediate level of portable communication board form equipped with picture symbol and voice-output capabilities, USB Interface for the students with severe and multiple disabilities. It adopted the System on Chip of C8051 system for this, and supplied and the conveniences such as the addition, deletion, editing and audio file management through the supply of the soft sound quality and the linkage with PC by supplying MP3 level of audio and USB interface.
But, the augmentative and alternative communication device developed in this paper is a fixed structure to be unable to change or rearrange the picture symbol, so, requires additional researches for these things because having difficulties in changing the instrument shape and producing a generalized symbol according to the various disability characteristics.
