Senate Staffer asks: "I am doing some research for U.S. Senator on technology advancements, specifically in the field of computer interfaces. Human-Computer interface tools have not changed for quite some time. The keyboard was grandfathered from the type-writer, and although there have been advancements (ergonomic designs, different key layouts, even different shapes), the basic function has not changed. The mouse was a major new advancement for computers, and again, although there have been advancements (track-balls, optical mice, trackpads, etc) the function has remained the same. What cutting edge technologies are being researched today and where? What technologies are currently available to consumers, and what technologies are on the horizon?"
