Who is in favour of empirical research approach?

Colleagues,

As far I know, there is only one article targeted to designers
 that presents clear arguments in favour of empirical research
(direct observation followed by statistical analysis)
as a way to guide design practice:
"To picture or not to picture: how to decide"
by Judith E. Sims-Knight.
Visible Language, v26 n3-4 p324-87 Sum-Fall 1992
*
Do you know any other one?*

I am sure that your suggestion will help
all academic researchers that follow our discussions.

Many thanks.
