I've read most of the threads related to increasing typing speed, which include many opinions and sound arguments on this topic. I want to make a new thread to consolidate and potentially find a greater degree of certainty.
Some things we can probably agree on to frame the importance & inspiration:
1) Keyboards are the highest bandwidth input device
2) Bandwidth is limited by your typing speed, for one.
3) Your typing speed is limited by factors we'll discuss here:
A) Ergonomics need to be great, but let's skip that preference related discussion to focus in. (I'm partial to the Kinesis design.)
B) The nervous system needs to know when to stop pushing/pressing & not over-do or under-do it
C) The tactile bump is only a hindrance if one can't get used to linear switches. The bump increases joint impact.
D) Typical 4mm travel keys are too deep to optimize for typing speed for anyone.
E) Butterfly switch-like travel are too shallow to optimize for speed - especially because you're bottoming out, which violates the above principles (worse than tactile bump).
F) Something less than ~3.4mm total travel seems ideal.
G) Spacer rings seem ideal: reduced stress from bottoming out, reduced travel.
H) Can we get used to very light linear switches to optimize speed? Maybe.
I) Can we get used to heavier linear switches to better use our entire muscular coordination without "holding back"? Maybe.
J) Should we use different springs (heaviness) for different fingers (at least thumbs)? It seems so.
That's what I have for now... Please state your full argumentation if you're going to enter this discussion/debate
Thanks - have a splendid & productive day!
P.S. Perhaps this should be in the keyboard forum and not ergonomics forum... Can we cross-post? Anyway, I'm trying to differentiate between "top speed we can type" versus "top speed the body will end up typing due to constraints, body protecting itself against RSI, etc..."
