A method of generating cursor motion signals for improved usability is
provided. In one embodiment, the method comprises detecting object motion
in a sensing region and providing cursor motion signals in accordance
with cursor motion values generated responsive to continuation of the
object motion in the inner region. This embodiment further comprises
providing cursor motion signals configured to generate cursor motion that
combines incremental cursor motion with additional cursor motion
responsive to the object moving from the inner region into the outer
region, where the incremental cursor motion comprises motion toward an
edge of the display correlating to an edge of the sensing region
proximate the object, and where the additional cursor motion comprises
cursor motion indicated by cursor motion values generated responsive to
continuation of the object motion in the outer region of the sensing
region.
