ABSTRACT:
A system for tracking and replicating the operation of a cursor manipulation device in a computer system is disclosed, wherein the computer system includes a monitor and a cursor manipulation device having an icon representing the location of a cursor on the monitor. The system for tracking and replicating includes recording apparatus for capturing a plurality of data points transmitted by the cursor manipulation device and a first multiplicity of events on the monitor. The datapoints and the events on the monitor occur while the icon travels between a first location and a second location on the monitor and the recording apparatus is also operative to identify the first and second locations. The system also includes apparatus for replicating the movement of the icon which includes apparatus for replaying the data points, apparatus for identifying a third location of the icon on the screen as a result of the replay of the data points and apparatus for causing the icon to move from the third location to the second location, if the third location is not generally identical to the second location.
