Hi Mauricio,
Thanks for the references.
Your PhD dissertation is very interesting and has points in common with my
work, since one of the phases is the redesign of the layout of blood test
analyses. And it's one of those issues, what better option(s) in terms of
elements graphics. Easily, we are conscious of what could be more
appealing, more readable, but why is another question.
Another issue is, how do we know which design elements should be used to
achieve this plurality of patients in the national health service, with so
different social, economic and cultural features , at the same time
providing with more personalized information, and therefore more credible,
about their own state of health? Which, hopefully, will lead to behavior
change.
I really would like to follow your work.
best,
Monica
