    Subject:  Perceived or actual complexity of systems
    I am seeking pointers to papers etc on the actual or perceived complexity 
    of programming languages, systems, interfaces, or processes relating to 
    computers (debugging, editing, etc).  Are there any good dimensions along 
    which to measure perceived complexity?  Have any experiments been done to 
    measure this?  (Note that the kind of complexity that we are interested in
    is not directly related to complexity of algorithms whose metric is of the
    sort: NSquared, or NLogN.  Rather, we are looking for measures in terms of 
    learning curves, or funnction use statistics (or anything else that might 
    indicate this sort of "human" complexity, not "mathematical" complexity)).
I'd reccomend looking at a paper by Beau Sheil of XEROX Palo Alto
Research Center "Coping With Complexity", CIS-15 (ssl-81-4) April 1981.
Also someone else at Xerox did a recent PhD thesis about the
complexity of using text editing systems (maybe Terry Roberts?); probably Beau
can give you pointers.
