How to unlock an iPhone with a ring. A man named Michael Knuepel has come up with a way to make an iPhone screen accessible with a secret ring. It sounds like something from a spy movie (a bad one) but he is perfected the proof of concept, as seen in the video after the jump.
I'm not certain how the ring works. Perhaps there is some sort of chip in there that sends a message to the iPhone that the key is in the lock so to speak. It reminds me of the days when messages had to be sealed with wax and a specially molded ring.
Granted, the ring in the video looks like something that only Green Lantern would wear, but if it could be put on a normal-sized ring, like a wedding ring or class ring, then we have a marketable iPhone accessory with the bonus of some added mobile phone security!
