From a cognitive model towards an assistive and augmentative written language
Résumé
This paper presents a discussion about assistive and augmentative natural language processing designed for certain disabled persons unable to communicate. Several approaches have been proposed, according to abilities of the writer. Here we distinguish two cases in the writers capacities: the writer knows alphabetic writing, or (s)he does not know it. In the first case, the idea is to assist the writer by completing the words or the group of words which are initially written. In the second case, pictograms are used instead of characters, but it must be decided if these pictograms represent concepts or words in a new writing system. If the pictograms represent concepts, the produced text may not correspond exactly to the wishes of the writer; whereas when the pictograms represent words, the writer has to change his (her) mental approach to write the words that (s)he has chosen in another way.
