Some dude from Ottawa has invented a nose-operated mouse, called a “Nouse.” The Register had this to say:
For 3D orientation, two webcams track the user’s snout and cunning software works out the distance from the PC, blah blah blah.
Excuse our sudden loss of interest in the scientific background to this earth-shattering innovation, but it is without a doubt the most singularly pointless waste of technology since someone bolted two wheels to a pogo stick and called it a Segway.
