| Sip/Puff Switches
|
| |
| A switch is an input device used to control assistive devices and computers. Sip-and-Puff Switches are activated by the user’s breath. For example, a “puff” might generate the equivalent of a keystroke or the click of a mouse. A sustained “sip” might be the equivalent of holding a key down. With an on-screen keyboard the user puffs out the letters while they can navigate the screen by sustained sipping. |
