Abstract
A method is provided for operating a bar-code system. A system has a screen that displays a graphical user interface that contains at least one control element. The method selects the control element to trigger an associated control command. The control element is a bar code that corresponds to the associated control command. The selection of the control element is performed when a bar-code reader reads in the corresponding bar- code from the graphical user interface, and the corresponding control command is generated and communicated to a device controller.
