IC60 Controlling a Speech Generating Device Through a Power Wheelchair

Program ID Number: CRS000712
CEU Course ID: P294.15
Webinar Length of Time: 1.0 hour

Link to view the lecture presentation:


For clients with limited motor control, finding an access method for both a speech generating device and for a power wheelchair can be quite challenging. If a client has limited switch sites, one or more switches may need to be "shared" to provide access to more than one assistive technology device. This course will present how a speech generating device can be accessed through a power wheelchair driving method using either switch or mouse input.
