Canadian Researchers are working on the nose-mouse, and other unorthodox ways of moving a cursor. From The New York Times
“The nouse, as the system is called, is among the latest in cursor-control methods designed to replace the hand-operated mouse.
Most of these systems, which are generally intended for disabled people, track head movements, and often require that the user wear headgear or attach a marker to the face. The nouse and another method that relies on tongue movements inside the mouth represent attempts to make such systems simpler and more useful.
“It’s not to replace the mouse,” Dr. Gorodnichy said of his invention. “It’s to add extra features to the computer.”
