title: AAC systems: obstacles to effective use.
abstract: This paper investigates some of the issues which contribute to the lack of use of Augmentative and Alternative Communication (AAC) systems. It presents findings from a two-year research study which examined the communication of 93 adolescent and adult AAC users with cerebral palsy and 186 of their communication partners. The methods of data collection were questionnaires, interviews and field notes. The results show that some of the obstacles to effective use of AAC systems include lack of availability and accessibility of AAC systems, communication partners' lack of knowledge of AAC systems, insufficient amount of therapy provided, type of vocabulary in AAC systems and other modes of communication available to AAC user.
