While mind-control interfaces are all well and good, sometimes a simpler solution makes a bit more sense, and that's where this so-called Copycat Arm comes in. Developed by a group of researchers at the University of Tsukub, it makes use of a high-speed camera to monitor a person's movements, which are apparently instantly (and creepily) mimicked by the robot arm.Eventually, the researchers say the same system could be used as a computer interface, which they say could eliminate the need for a mouse and keyboard. Unfortunately, there doesn't appear to be a video of the arm in action, but those heading to SIGGRAPH 2008 will apparently be able to check it out first hand.
