Comment Re:Chord Keyset? (Score 1) 140
Doug was using the buttons on his "keypad" to type, as well as issue commands. It has a very limited input set, not as large as a standard keyboard. But, within that input set, some people have been able to get about 25 words per minute.
It works like this: each individual key has a value. And each combination of keys has a value. So, for example, pressing the button under your thumb may correspond to the letter "a". While your other fingers may be "b", "c", "d", and "e".
Pressing both your first and second finger may input an "f". Pressing your first and third finger may input a "g".
If I remembered enough combinatorial mathematics, I could tell you how many combinations there are in 5 buttons. But, I'll just leave it as something between 26 (the alphabet) and 110 (a normal keyboard).
On a side note, I'm really glad to see that this video is getting such wide distribution. I haven't seen it in a while. But in case they don't mention it, this was done across a wireless network! The packets were transmitted between trucks parked on top of hills.
