METHOD AND APPARATUS FOR SYNCHRONIZING VIRTUAL AND PHYSICAL MOUSE POINTERS ON REMOTE KVM SYSTEMS

摘要

A method and system is disclosed for synchronizing the virtual and physical mouse cursors of a local computer and a remotely controlled computer. Video signals generated by a host computer are transmitted to a client computer in order to allow the user of a client computer to have a virtual presence on the host computer. However, the signals transmitted by the host computer may contain errors that can cause a physical mouse to lose synchronization with a virtual mouse. Therefore this virtual presence architecture uses USB protocol and human interface descriptors that support the movement of a mouse to an absolute position in order to synchronize a virtual mouse cursor with a physical mouse cursor.

主权项

1. A method of providing mouse synchronization, comprising:
utilizing universal serial bus (USB) protocol to provide movement of a mouse cursor on a host computer to an absolute position, and synchronizing the position of a logical mouse and the position of an actual mouse using the absolute position information without operator intervention.
