Access interface strategies.

Individuals who rely on augmentative and alternative communication (AAC) devices to support their communication often have physical movement challenges that require alternative methods of access. Technology that supports access, particularly for those with the most severe movement deficits, have expanded substantially over the years. The purposes of this article are to review the state of the science of access technologies that interface with augmentative and alternative communication devices and to propose a future research and development agenda that will enhance access options for people with limited movement capability due to developmental and acquired conditions.

Evaluation of a speech recognition prototype for speakers with moderate and severe dysarthria: a preliminary report.

This study described preliminary work with the Supplemented Speech Recognition (SSR) system for speakers with dysarthria. SSR incorporated automatic speech recognition optimized for dysarthric speech, alphabet supplementation, and word prediction. Participants included seven individuals with a range of dysarthria severity.

Use of safe-laser access technology to increase head movement in persons with severe motor impairment: a series of case reports.

The purpose of this article is to describe the impact of an intervention involving safe-laser pointing technology on six persons with locked-in syndrome. When these individuals were invited to participate in this project (4 weeks to 18 years post onset), none were able to speak and none were able to access an augmentative and alternative communication (AAC) device. All communicated using eye movements (e.
