Study: Stroke victims may retain continuous motion ability
...its own sake. "Suppose you are trying to design a device to help a brain-damaged patient interface with the world," he said. "Many such devices make use of 'point-and-click' technology, such as many of us use at our computers. But pointing and clicking are just the sort of interrupted, discontinuous motion...... alternating baths of clay and polymer. A robotic device performed the 200 dips, with each dip producing several plastic-clay layers--each clay and plastic layer is, on average, only 24 nanometers thick.
