US 2010/0060571 A1 · KVM SWITCH USING A TOUCH SCREEN

Abstract

A KVM switch system having a touch screen for interacting with multiple computers is disclosed. The KVM switch processes coordinate data from the touch screen and transfers the processed data to the controlled computer either as absolute mouse coordinate data or as relative mouse coordinate data depending on the operating system (Windows, Mac OS, SUN, etc.) and mouse data interface (USB, PS/2, etc.) used by the computer. Thus, the touch screen can interact with all computers connected to the KVM switch, achieving a multi-platform and multi-interface application without requiring device drivers on the computers. The KVM switch stores necessary parameters for each computer so that when switching from one computer port to another, or when the display resolution of the computer changes, processing of the touch screen data is automatically adjusted accordingly. The touch screen also works within the OSD of the KVM switch.

Dependent claims

A KVM (keyboard-video-mouse) switch comprising:

a plurality of computer ports each for connecting to one of a plurality of computers;
at least one console port for connecting to a user console which includes a touch screen;
a switching section for selectively connecting one of the plurality of computer ports to the console port;
and
a control section connected to the switching section for controlling the switching section,
wherein when a type of operating system of the computer connected to the selected computer port is determined, the control section receives touch screen coordinate data from the touch screen via the console port, converts the touch screen coordinate data to absolute mouse coordinate data or relative mouse coordinate data or both, and outputs either the absolute mouse coordinate data or the relative mouse coordinate data to the selected computer port depending on the type of operating system of the computer connected to that computer port.
