Scientist Invents Invisible Key

I'm not exactly sure how this will directly affect professionals in the near-term, but Japanese scientists have developed a digital key system that works similarly to the Nintendo Wii and Xbox. The technology, which they say is less than two years from commercial distribution, would allow people to make simple hand gestures, which the system would then interpret using 3-D motion sensing detection. It would be usable with virtually any kind of locks and key-based ignition systems, if manufacturers in those industries implement it. While it might be distracting to have to perform the "secret handshake" to get your car started (and I think I still prefer remote key lock clickers), it might have the uninteded benefit of decreasing drunk driving, as the occasional sot might not have the hand control or memory of the gesture required.
