Interaction design rules of thumb - do they exist?
- Just now a coworker asked me a question on inputing numbers into a text
box... the form is asking for a number that can be up to 8 digits
long. He asked what seem like simple questions:
do you restrict data entry to only digits?
do you restrict entry to only 8 digits?
The very unsatisfying answers I give to questions like these are "It
depends." I'll ask "how is number entry handled elswhere in the
application?" "Are the users doing heads-down data entry, or are they
filling out the form more interactively?" "What are the numbers being
entered? - what do they represent?" This line of questioning usually
gets in the way of the hard and fast answers people are looking for.
So my question for this group is: does a book/reference of boilerplate
UI/IxD rules of thumb exist?
Or, secondarily, is there a good place to track down usability research
on specific topics - such as the best way to enter numbers into form
- For me, I found sequence diagrams work well. Buy it may just be my style.

BTW, one of the things that doesn't work often enough is asking the users to report what they were doing. Many times I have seen users do one thing and then tell me that they did it differently. I would have doubted my sanity if I hadn't had co-observers with me.
Does this happen even in talk-aloud situations?
