I need to prepare a presentation on the latest I/O devices. I selected infrared/virtual/optical keyboard, but when I researched a bit, I found that was invented and patented by IBM engineers in 1992. :/ Although I read about it in a magazine as one of the latest innovations.
So, much for LATEST....
Can someone elaborate that...
and if infrared keyboard is not a latest technology can someone name any latest I/O device?
