<i>"He resumes typing. Only this time he is typing on…nothing. Just the flat tabletop. Yet the result is the same: The words he taps out appear on the monitor. The text on the screen is being generated not by his fingertips, but rather by the signals his brain is sending to his fingers. The armband is intercepting those signals, interpreting them correctly, and relaying the output to the computer"</i><p>This is a pretty neat idea, but I feel not being able to see the keyboard is kind of going to ruin this one. Even with touch typing you need some feedback as to where the 'F' and 'J' are, and even then you can't reach the whole keyboard. I suspect you can work around that with some sort of 'finger swipe' language though.<p>But what about the mouse? Being able to put your hand on something is lot more comfortable than, for example, using a touchpad on a laptop. The problem with these sort of devices (reminds me of the wii remote) is all the stress is moved to the fingers and wrists, which doesn't pay off well in the long run.
