I developed the following PowerPoint presentation as part of my graduate certificate in assistive technology study at Northern Arizona University. It documents my first expereince with the Impulse Switch and using it in combination with an onScreen keyboard and a head mouse, see links below.
The combination allowed me to control my laptop and create a simple MSWord document with only head movement and a forearm muscle twitch.
