ABSTRACT:
A non-intrusive cursor synchronization system is described that does not change or modify the existing system or application. The cursor synchronization system is used for synchronously displaying a cursor on a plurality of display systems connected together via a network without requiring database or shared memory. The cursor synchronization system includes a plurality of agents, each being coupled to one of the display systems to cause the respective display system to display a consistent cursor movement, and to trigger concurrent execution among a number of existing applications. The cursor synchronization system also includes a cursor synchronizer that captures and compresses the cursor movement generated from one of the display systems within a time interval that is adjustable based on the speed at which the user moves the cursor. The cursor synchronizer synchronously sends the compressed cursor movement to each of the agents such that the cursor movement is synchronously displayed on each of the display systems with minimized network traffic through the network. A method for synchronously displaying a cursor on a plurality of display systems connected together via a network is also described.
