[ACT-R-users] Model of writing

[Bonnie John]

We have a lower-level model of typing implemented in ACT-R tht is 
"under-the-hood" of CogTool. It is a mixture of my ages-old PhD thesis 
and what we cold do in ACT-R without changing the entire structure of 
its hand and fingers. So it still has remnants of ACT-R's typing 
assumptions, like the the hand always goes back to the home-row between 
each keystroke, but we have relaxed some of the other assumptions in the 
standard ACT-R typing model and so have sped it up to being about a 40 
wpm typist instead of the 20 wpm typist it is in the general release.

It was always on our ToDo list to make this code available to the ACT-R 
community similar to how EMMA is available, but I guess that has fallen 
through a crack. But we would be happy to share what we have.
Don (Morrison), can you please respond with an explanation of how 
CogTool produces ACT-R code that types as fast as it does and how that 
ACT-R code does what it does?

Thanks,
Bonnie
