I’m starting to design a Kaleidoscope plugin, and I’m concerned about how well it might work for very fast typists (which I am not — I probably manage no more than 40 words per minute). My primary curiosity is about keypress overlap (when one key is pressed before the previous one is released), and in particular how often (if ever) a very fast typist might have more than two keys pressed simultaneously (but momentarily) in the course of normal typing — not counting modifier keys being held.
I’m also curious about the length of time that keyswitches are typically closed (on) during a normal “tap” (as opposed to being held) — again, during the normal course of typing, not other types of input activities, like game-playing.
Does anyone know where I can find data on this topic? Even better — is anyone here interested in helping to gather that data? (I believe this could be done in a number of ways, but the best might be yet another Kaleidoscope plugin, using the serial interface)
