Nouse: A nose-steered mouse

Sore hands? How about taking the strain off them with a mouse you control with your nose? A Canadian team has come up with the "Nouse". The Nouse uses face motion, specifically zoning in on the nose, to control computer applications. It works with a USB or Firewire camera. For now, it looks like you need to run Windows to make use of the software. If you want to give it a try, check out the Nouse downloads page.
