Sensor Operated Augmented Fingers

In CACM:  More in the sensor and robotic space space.  The advances continue.  Human augmentation.  " ...  Massachusetts Institute of Technology researchers have developed a robotic extension to the human hand that could make common, everyday tasks easier. The extension, which is essentially two extra fingers, could be used to grasp, leaving the hand free to do other tasks. The extra fingers use sensors attached to the human hand to measure the position of the wearer's fingers, and an algorithm controls the output from the sensors to the robotic fingers.  ... "
