Perspectives on AAC systems by the users and by their communication partners.

The study examined the perspectives of augmentative and alternative communication (AAC) users and their 'formal' and 'informal' communication partners in relation to two areas of relevance to AAC: firstly, communication strategies, and secondly, advantages and disadvantages of AAC systems. With respect to communication strategies, it was found that formal communication partners thought that more vocabulary for communicating social purposes was actually available to AAC users and they were less aware of daily routines within day and residential environments. With respect to advantages and disadvantages, three main areas of concern emerged: the effect of the AAC system on the users' communication; features of AAC systems; and the effect of AAC on the users' quality of life. Both high- and low-technology AAC systems were seen as having advantages and disadvantages. This study demonstrates the important contribution to be made by AAC users in the provision of a new set of priorities based on their user experiences.
