Abstract
Communication is a basic need for all humans. It allows us to transfer our own ideas to society and in exchange learn new things from others. Most of humanity uses speech to communicate, however, around 1% of the population is not able to do so including those with developmental disabilities, neurogenic disorders, and degenerative neurological conditions. Augmentative and alternative communication (AAC) refers to any communication that is done without talking and is necessary for all people regardless of their ability to speak properly. Naturally, however, people with speech and language problems rely on AAC more than those with regular speech abilities. A popular form of AAC are digital communication boards, categorized grids filled with pictographs allowing the user to point and convey their thoughts. This thesis, Chatterbox, is a framework for a low-budget AAC application. It demonstrates that AAC mobile applications need not be expensive, allowing communication to be easily attainable by as many people as possible.
