Sorry if this is a bit of an esoteric request but I'm hoping someone
can help - I'm not even sure what keywords to use for these searches.
(All the results I get back are talking about multiple windows in
standard desktop OSes or applications. It's even more frustrating
because people are inconsistent in what they call a 'screen' or
I'm looking for research on rates, types, and descriptions of errors
made by people who have work environments with multiple screens. In
the domain where I work (financial services) it's common for people to
have two side-by-side displays and some people have as many as six
(often stacked 3 wide by 2 high).
I've begun working in such an environment myself, having two
side-by-side screens and I observe that I make a number of errors in
this format that I do not make in single-screen situations. For
example, it's VERY common for me to shift my gaze and mental focus
from one screen to another and begin typing as though the
cursor/window focus had followed my gaze.
Informally I feel like I make this category of error much more often
than I make the comparable error with two windows side-by-side on one
physical screen. But of course informal self-observation isn't highly
reliable data. So as a designer I wonder if there are such data that
would aid me in designing better multiple-screen interfaces.
