It's no Picasso, but if s a start. A robotic arm that can be controlled with your eyes has just painted its first picture: a simple image of a house, grass and the sun. Developed by Aldo Faisal of Imperial College London and his team, it extends the human body by providing a third, artificial arm. "It's the first step to human augmentation with additional limbs," says Faisal. The arm uses an off-the-shelf eye-tracker to follow a person's gaze, sending instructions for movement depending on how and where the painter looks. The commands can move the arm instantly using, for example, fixed gazes and sequences of prolonged blinks. A person can get it to paint a horizontal line by staring at a start point and then an end point.
