Picture Exchange Communication Systems (PECS) are a form of augmentative and alternative communication that uses pictures to help individuals express their needs and desires. This system is especially beneficial for those with speech or language difficulties, such as individuals with autism or other developmental disorders. Users learn to exchange pictures for items or actions, promoting communication through visual means. PECS typically involves several phases, starting with simple exchanges and gradually increasing in complexity. As users become more proficient, they can create sentences with pictures, enhancing their ability to communicate effectively. This method fosters independence and encourages social interaction by allowing users to express themselves clearly.
