Abstract:
A feedback subsystem may be used to control the positioning of a local cursor of a display in response to receiving remote cursor movement information from a remote computer system. The feedback subsystem may send the remote cursor movement information to an operating system (OS) which may send local coordinate information to a graphics controller. Local coordinate information from the graphics controller may be used to compare with remote coordinate information received from the remote computer system. The feedback subsystem may repeatedly send the remote cursor movement information to the OS until it is determined that the local coordinate information from the graphics controller is consistent with the remote coordinate information received from the remote computer system.
