Researchers Design a Breath-Operated Computer Interface
From: IEEE Computer Magazine - 02/2008 - page 25

Two Georgia Tech University researchers have developed a way for users to
blow at their PC or laptop screens to control interactive applications. 

The Blowable and Localized User Interaction interface that doctoral candidate
Shwetak Patel and professor Gregory Abowd developed could help people work
with computers when they can't use their hands because they are either busy
with other tasks or have a disability or injury. 

BLUI lets a user blow at the part of a screen on which an application control
- such as a button, cursor, or even scroll bar - is located.
