Robot always wins rock-paper-scissors
The purpose of this study is to develop a janken (rock-paper-scissors) robot system with 100% winning rate as one example of human-machine cooperation systems.
Here's how it works. The robot includes a high-speed camera that watches its human opponent's fingers. Think HAL from "2001," only not as homicidal. The incredibly fast camera determines whether the person is about to use a fist (for a rock), palm (for paper), or two fingers (for scissors). The robot makes its choice accordingly, well before the human opponent lays down his or her choice. If the robot's camera sees you forming a fist, the robot's going to drop a smothering piece of paper -- and there ain't a darn thing you can do about it.
