Sip-and-puff

Sip-and-puff technology is a method used to send signals to a device using air pressure by "sipping" and "puffing" on a device called a "straw" or "wand." It is primarily used by people who do not have the use of their hands. It is usually a type of wheelchair mechanism for people with quadriplegia with very high injury.

The mouth-controlled input provide people with quadriplegia a simple and effective way to control mouse movement. Movement and operation of this joystick is similar to that of a 'Mouthstick'. Mouse button clicking is accomplished with the help of sips or puffs function of the joystick.

A sip-and-puff input device combined with scanning software means many keyboard-accessible programs can be used with this device.
