The document discusses a concept coding framework called CCF-Droid for symbol supported augmentative and alternative communication (AAC) on Android mobile devices. CCF-Droid allows users to communicate using Blissymbols and ARASAAC symbols with text-to-speech. It also enables vocabulary editing by looking up words and symbols from an online CCF Symbol Server. A pilot test of CCF-Droid is upcoming to evaluate face-to-face communication and indirect messaging with the tool. Integration with alternative input methods like Tecla will also be added.
