PC users follow their nose

摘要

Tired of using a mouse to control your PC? Perhaps there is another option for when your arm starts to ache: your nose. A novel PC control system lets users nudge a cursor around the screen with gentle movements of their nose. Blinking the left or right eye twice takes the place of left or right mouse clicks. The inventor, Dmitry Gorodnichy of the Institute of Information Technology in Ottawa, Canada, calls his nose-steered mouse a "nouse". In addition to giving people a change from the keyboard and mouse, he hopes it will make using a PC easier for people who have a disability. And it could also provide more intuitive ways for people to explore computer-generated environments or play three-dimensional video games, he says in the journal Image and Vision Computing (vo1 22, p 931).
