Nothing really new here
A while back I did a patent search for any patents of my grandfather and found a pair of them from the late 20's when he worked for the Western Union Telegraph Company. One was a device with a keyboard that used a rotating cylinder with a slot cut in it, a light, and a photo detector to turn typed letters into Morse, then there was the companion device which converted Morse into text.
This is pretty much a 21st century version of the same thing... and I sure wish I could tell him about it. (never mind how I found out about his patent, that would really blow his mind!.
