Operate on a beating heart

The New Scientist describes a robotic system which can compensate for the motions of the heart, allowing surgery to continue while the heart beats (gently). The surgeon wears eyepieces which track his gaze. He first scans over the heart; then tracks the beating motion of a single region; and the machine calculates the topography of the heart and its motion from that point forward. This means that the surgical tools stay stationary with respect to the heart.
