Wireless Sip and Puff Switch (WISP)

WISP uses the power of your breath!

WISP uses breath to perform switch closures. It uses a very discreet air tube that mounts on the ear with a mouthpiece that you sip or puff on. The tube connects to a pager-sized battery-operated transmitter belt-pack. This transmitter sends switch closures wirelessly from more than 40 feet away to a receiver (usually a Tracker) whenever the user sips or puffs on the tube. The receiver plugs into Tracker and performs the mouse button functions: puff for left mouse button, sip for right. It can also be used independently of Tracker to provide sip/puff activation to anything requiring a single switch. WISP accepts up to two regular ability switches (1/8” jack) allowing it to double as a wireless switch transmitter. Fully FCC certified for use in the home, hospital, school, or workplace. All you need is a switch interface, such as the Tracker, into your computer system.
