Powerful, portable, off-the-shelf handheld devices, such as tablet based computers (i.e., iPad®; Galaxy®) or portable multimedia players (i.e., iPod®), can be adapted to function as speech generating devices for individuals with autism spectrum disorders or related developmental disabilities. This paper reviews the research in this new and rapidly…

This study combines multi-mice technology (people with disabilities can use standard mice, instead of specialized alternative computer input devices, to achieve complete mouse operation) with an assistive pointing function (i.e. cursor-capturing, which enables the user to move the cursor to the target center automatically), to assess whether two…

This commentary includes a brief discussion of issues raised by the articles and systematic review contained in this special issue addressing technology applications for persons with severe developmental disabilities. Topical areas include a discussion of: (1) a need to compare "high tech" with "low tech" applications, (2) procedural fidelity, (3)…

The number of children receiving cochlear implants (CIs) with significant disabilities in addition to their deafness has increased substantially. Unfortunately, children with additional disabilities receiving CIs have largely been excluded from studies on cochlear implant outcomes. Thus limited data exists on outcomes in this population to guide…

This study compares use of the Picture Exchange Communication System (PECS) and a Voice Output Communication Aide (VOCA) with four preschool children who were either non-speaking or limited in their ability to speak and did not use an AAC system to communicate functionally. An alternating treatment single subject design was used to measure…

This paper provides an overview of the literature dealing with the use of the Picture Exchange Communication System (PECS) and voice output communication aids (VOCAs) for promoting the performance of requests by students with developmental disabilities. Computerized and manual searches were carried out to identify the studies published during the…
