OH how true!!!!!
The sad truth is for all of us eye tracker designers that fondly imagined a
super duper eye controled computer was just around the corner, it turns out
that the eye is hardy EVER conguent with the mouse. An eye controled
computer would have to use a competely dedicated user interface and so is
unlikel;y ever to be a mainstream product. It can be wonderful of course for
people that have no use of the arms but it is never a "natural" wa to
control an interface. The two areas that terminally defeated our efforts
were spreadsheets and drawing programs. Where due to box dragging and other
inputs the ee is in fact only congruent with the mouse for five percent of
interactions.

Michael -
Although eye movements almost always precede reaching / grasping movements
to objects in the world around us, the reverse is not true (e.g., we don't
reach to everything we look at). In the lab at the University of Rochester,
we see the same pattern in graphical interfaces: eye movements to objects
presented on a computer monitor which slightly precede the mouse cursor
pointing / clicking. But, as you would expect, we also see eye movements to
other objects on the screen that are not accessed with the mouse-driven
cursor. These other eye movements - even in very routine tasks - seem to
play an important role in short term memory.

Subject: [EM_LIST] gaze and mouse-tracking behaviour
Hello!
I am looking for empirical evidence for the relation between gaze behaviour
and clicking behaviour for internet usage.
I suppose that in the field of graphical user interfaces eye and mouse
movements are somewhat related. If so, complicated eye tracking could be
substituted by mouse tracking at least for some research purposes.
Does anyone know studies that tackle this argument?
