Abstract
A system and method wherein touchpad input including movement of a cursor and mouse clicks are inhibited until two events have occurred, namely, a timeout interval has elapsed and detection of movement of a pointing object a predetermined distance on the touchpad, wherein the system and method may also be implemented in touchpad firmware or hardware so that touchpad functionality beyond functions offered by an Operating System will travel with the touchpad and be available even when a software driver offering extended touchpad functionality is not installed or available for use.
