Communication is an important and required activity to everyone in our socieity. In general, people use oral language to communicate. Our language ability is improved by interation with others from we were babies. Using language to communicate is the easiest and most convenient way. However, there are still many people in the corners of our socieity lost this communication tool by diseases, heredity, or injury. According to the statistics of Ministry of Health and Welfare, the disable population in our country is more than 1.1 million by 2013. The communication disable population is over 135 thousands. If the mental retardation and learning disability population are added together, the total number of potential communication disability population will exceed 300 thousands. These people have only limited ability to describe their necessaries. It causes problems of them to communicate with others. In the long run, they will gradually give up the communication. We use information technology (IT) to make better of this situation. Our study is to build a softwar system (or app): Icon Language Communication Platform (ILCP), on tablet computers/smart phones which using graphical icons as input units to create meaningful and completed sentences. ILCP is designed for spoken language barrier, learning disability and those who dislike traditional Chinese input methods. We have three principles in our research when designing ILCP: 1. fewer input work better; 2. helping people communication; 3. helping people express their daily life requirements Following our research results, we use 130 core vocabularies on ILCP front page. These 130 vocabularies are separated into 10 categories. These 10 categories vocabularies are scheduled from the bottom up the top on the screen. Common words can be found at most in three times of mouse strokes in general. In additions, among the 10 fringe vocabularies, each has other 86 vocabularies. The scenario category also has 10 scenarios on ILCP so far. Each scenario has 99 vocabuaries. Therefore, on ILCP, we have 130 core vocabularies on front pages, and 1691 fringe vocabularies on the second page. ILCP can help users to input and compose sentences by icons. A complete sentence then can be spoken out for communication. ILCP is a very helpful tool in the medical cares and special educations.
