As a way to help children dealing with cognitive and motor-skill disabilities, researchers from Georgia Tech have developed a rehabilitation tool that pairs a robot and an Android tablet. To demonstrate this system in action, the research team used Angry Birds to let kids teach the humanoid how to play Rovio's popular game. Essentially, the robot is smart enough to learn by simply watching each move the child makes while flinging those birds toward the iconic green pigs. "The robot is able to learn by watching because it knows how interaction with a tablet app is supposed to work," writes project leader Ayanna Howard, a professor at Georgia Tech. "It recognizes that a person touched here and ended there, then deciphers the information that is important and relevant to its progress."
