(a) The
problem: at high mouse speeds, the mouse cursor seems to jump from
one position to the next.
(b) Solution: High-density cursor makes the mouse cursor appear more
continuous by inserting additional cursor images between actual
cursor positions. |
As bigger screens and multi-monitor configurations become more popular,
users employ higher mouse accelerations in order to traverse the screen
reasonably quickly. The faster the mouse cursor moves, however, the more
it seems to jump from one position to the next, as it is updated only at
the refresh rate of the monitor. This lack of visual continuity
increases the risk of users losing track of the cursor. High-density
cursor addresses this issue by filling in additional cursor images
between actual cursor positions (temporal supersampling). Unlike
existing techniques, such as the Windows mouse trail, the
proposed technique preserves the responsiveness of the mouse cursor. In
our user study high-density cursor improved participants’ performance on
a Fitts’ law task by up to 7% for target acquisitions across long
distances. Moreover, the conditions of the high-density mouse that were
tested were subtle enough that they were often not even detected, and
were never considered distracting.
