When adapting the Picture Exchange Communication System (PECS) for an individual with significant motor impairments, the MOST critical consideration is ensuring accessible and functional communication through alternative methods for picture retrieval and exchange, prioritizing augmentative and alternative communication (AAC) strategies that bypass or minimize motor demands. PECS, at its core, is a system where individuals use pictures to request items or activities. However, significant motor impairments—meaning limitations in movement and coordination—can make the standard PECS procedures, which involve reaching for and exchanging pictures, extremely difficult or impossible. Therefore, direct adaptation of the original PECS protocol is often insufficient.
The primary challenge lies in the physical act of accessing and transferring the picture cards. Standard PECS typically requires the individual to reach for a picture, hold it, an....
