Gary writes with a link to a Wired article about a brain-machine interface that may eventually have practical purposes. Though right now it simply allows a user to move a train on a track by performing math in their head, someday it may result in more serious applications. "Honda, whose interface monitors the brain with an MRI machine like those used in hospitals, is keen to apply the interface to intelligent, next-generation automobiles. The technology could one day replace remote controls and keyboards and perhaps help disabled people operate electric wheelchairs, beds or artificial limbs. Initial uses would be helping people with paralyzing diseases communicate even after they have lost all control of their muscles. Since 2005, Hitachi has sold a device based on optical topography that monitors brain activity in paralyzed patients so they can answer simple questions - for example, by doing mental calculations to indicate 'yes' or thinking of nothing in particular to indicate 'no.'"
