Alternative access methods for accessing AAC systems for individuals with severe physical impairments
by Thompson, Ginger Kay, M.S., THE UNIVERSITY OF TEXAS AT EL PASO, 2007, 47 pages; 1444074

Abstract:

Access Methods have been a major issue in the field of augmentative and alternative communication (AAC) for many years. There are studies about teaching access methods which have focused on operating scanning as an access mode. Utilizing scanning as an access method, however, is time consuming and often fatigues the individual who uses AAC. New technology has been developed which utilizes brainwaves and/or minute electrical impulses associated with minimal muscle movement. Cyberlink is a system in headband form which senses facial/eye movement and brainwaves as an access method. This investigation studied the effects of instruction cues on the acquisition and implementation of access skills while using Cyberlink by an individual with severe physical disabilities who used AAC. A single subject design was used to reveal that after a period of instruction the participant was able to utilize the Cyberlink to create predetermined sentences. Limitations and future research directions will be addressed.
