Somewhere very high up on the list of dangerous inventions - just below the electric bath-water reheater - you'll find the Nouse, a new nose-steered navigation system for PCs, as featured today over at New Scientist. Apparently a camera is used to watch the user's nose-navigation movements, interpreting them with sophisticated image-analysis algorithms. Blinking an eye, meanwhile, acts as the equivalent of clicking a conventional mouse (presumably the right eye is for right-clicks, which could prove tricky for those who aren't very good at winking). Some commentators suggest that the invention, dreamed up by Dmitry Gorodnichy, will fail to achieve mass-market appeal due to the fact that users might feel somewhat foolish winking, blinking and waving their conk around to compose a document. But Sneak foresees a slightly more dramatic drawback. Who wants to suffer a sneezing fit and then open their eyes to find that they've accidentally replied to that spam offering a lifetime's supply of cut-price pharmaceuticals, sent eighteen messages of gibberish to the HR director, lodged a £20,000 bid for a signed photo of David Hasselhoff on eBay, and clicked "yes" to that "Format C: Are you Sure?" prompt...
