Abstract

The invention discloses a key-screen-mouse KVM switch system having a touch screen for interacting with multiple computers. The KVM switch processes coordinate data from the touch screen and transfersthe 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 ofthe computer changes, processing of the touch screen data is automatically adjusted accordingly. The touch screen also works within the OSD of the KVM switch.

Description

technical field

[0001] The invention relates to a keyboard-video-mouse (KVM) switcher, in particular to a KVM switcher using a touch screen as a user interface to interact with multiple connected computers. Background technique

[0002] Touch screens are widely used in the interaction between users and electronic devices, such as automatic teller machine (Automatic Teller Machine; ATM) systems in banks, automatic ticket vending machines in mass transit systems, tablet computers, and the like. Conventional touch screens are designed for specific electronic devices and generally can only be used in corresponding electronic devices. For example, the touch screen used in the ATM system can only operate in the mode of the ATM system. Therefore, due to hardware differences in different electronic devices, the traditional touch screen cannot interact with many different electronic devices.

[0003] One example of a touch screen being applied to a KVM switching system is the "KVM d...
