People can develop their own PCS for certain needs or if the needed symbol is not available. PCS symbols have been translated to 40 different languages. The PCS set comprises a core library of roughly 5,000 symbols, supplemented by general-purpose addendum libraries and country-specific libraries for a total of 37,000+ symbols. The communication interventions for individuals who have little or no speech have used PCS successfully for individuals.

Because of high transparency, PCS symbols are easy to learn by children with little or no speech. A graphic symbol is transparent if "the shape, motion, or function of the referent is depicted to such an extent that meaning of the symbol can be readily guessed in the absence of the referent" (Fuller & Lloyd, 1991, p. 217). Several studies have found PCS to be more transparent than other graphic symbols such as Blissymbols (Mizuko, 1987).
These AAC systems may be high-tech (Dynamyte) or low-tech such as a communication board. Picture communication symbols ( PCS) are a set of colour and black & white drawings originally developed by Mayer-Johnson, LLC for use in augmentative and alternative communication (AAC) systems.
