Innovations in computing sensors for touch, sight, hearing, taste, and smell are, according to IBM researchers, “the five technologies that are likely to advance remarkably over the next five years.” These innovations are key to what is called cognitive computing. “The idea is that in the future computers will be increasingly able to sense, adapt and learn, in their way.”  Source: “IBM Looks Ahead to a Sensor Revolution and Cognitive Computers,” by Steve Lohr, The New York Times.
