As robots become more artificially intelligent, one might assume that someday they could be programmed to read your very thoughts. This would make for a very frustrating game of rock-paper-scissors (or roshambo or janken depending on who you talk to).
Engineers in the Ishikawa Oku Lab at the University of Tokyo already developed this rock-paper-scissors master, but, as Popular Science explains, "there’s no algorithmic wizardry or predictive computation here." The robot is cheating. Using a high-speed camera, within one milisecond the robot hand can figure out what shape you'll be throwing down with your hand.
Watch the video and see if you can tell:
According to the experiment's website, this technology shows "a possibility of cooperation control within a few miliseconds," with the vision of it being used for humans who need some sort of robotic help or for tasks that are done in cooperation between humans and robots.
