||(left) When trying
to move the mouse pointer straight to a target on the other screen
of a multimon setup the pointer gets warped, because (middle) the
reason is that the system is oblivious of resolution differences and
gaps. (right) Mouse ether eliminates warping, allowing users to
acquire all targets on the direct path.
When acquiring a target located on a different
screen, multi-monitor users face a challenge: differences in resolution
and vertical and horizontal offsets between screens cause the mouse
pointer to get warped, making the attempt to acquire the target
difficult. Mouse ether eliminates warping effects by applying
appropriate transformations to all mouse move events. In our user study,
mouse ether improved participantsí performance on a target acquisition
task across two screens running at different resolutions by up to 28%.
7 of the 8 participants also strongly preferred using mouse ether to the

ether, users need to perform only three drag interactions.
||Another benefit of
mouse ether: Without mouse ether, the mouse pointer can get blocked
at screen borders on the way. Mouse ether avoids that by allowing
the pointer to temporarily travel through off-screen space.
