Multiple Sclerosis sufferer Eileen Brown from Braunton in Devon uses assistive technology in the form of sip-and-puff to write short stories and a novel after seven years of not being able to write due to her condition. Sip-and-puff uses air pressure by inhaling by sipping or exhaling by puffing through a special mouthpiece or wand which controls the typewriter and is based on the principle of morse code.
